[@manuell3505]

x3mw: It depends on which level. A Pentium or later with just a Z80 emulator + somthing like SDL as video-framebuffer is not as complicated as porting on instruction-level to a 8086 with EGA...

[@catlover10192]

"Professional" game development was honestly often a lot like that in the 80s.

Exactly what happened back in the day.

[@madyogi6164]

Yea, I never thought C64 be that popular, after the x86 era. Hats of to those who stuck with 8 bits out there.

[@Dorelaxen]

Concerning the box artwork not conforming to the game itself, I say embrace it. Look at all the Roger Dean weirdness that defined early computer game artwork, or the boxes for the 2600. Breakout was awesome, but I don't remember there being astronauts and spaceships in the game.

[@coffee115]

Dorelaxen I always liked seeing the box, the manual, and the game as a whole, it really put your mind into that “mode’ where this was way more than a game.

[@pkaulf]

Yeah, good box art was able to really fire up the imagination in ways that the actual graphics couldn't. I must say the box art for Planet X2 looks very authentically 80s, can almost imagine it being airbrushed

[@EpicTyphlosionTV]

You could totally make an updated version that requires a RAM expansion (like 192k for a C64 and 128k for a C128), but includes many of the features and such that got cut

When I was a kid I wrote a program on my C64 that would pick lottery numbers while playing the theme from Dallas and I thought it was a big deal.

[@andrewhamop6665]

Cool man

[@UberAlphaSirus]

lol, me too, I was crap with the sound system though, so no sound.

[@rodmunch69]

I think that was the most complex thing I did in basic - I just remember having to write out the notes one by one and how long each one would play and having very little understanding of anything I was doing - but shockingly it worked. A ball would bounce around the screen then six numbers, between 1-49 would appear one by one - and as I said it did it while playing the theme to Dallas. Why Dallas? I have no idea - probably because it was the most simple sheet music I had available to work from.

As a graphic designer, I find the packaging and manual VERY aesthetic. This game looks amazing, too! You're super talented, dude!

[@winnetouch]

As another graphic designer and illustrator I think the box layout is cool (but that's not really hard to achieve since they just copied the formula of older games) but the artwork... Weeeellll... I don't want to be rude but the artwork isn't really top notch.

[@ChrissehCat]

I think the artwork is just trying to emulate the style of artwork that was often seen on games of the 80s era. They were usually really cheesy like that, and usually a lot worse.

[@davidandrew7314]

Aesthetic is not a superlative, you need to add to it for it to make sense. Something can have a good or bad aesthetic so just saying the word alone doesn't describe your feelings.

[@BoogiemanXXL]

I have been around computers for most of my life, but since I was born in 92 and really only got smart enough to use one in around 2000, I have completely missed the early home computer days. I think I know a lot about modern computers, but the really interesting stuff (like how memory is addressed or how chips process data) is completely lost on me. I love your videos for going into so much technical detail, because that combined with the older hardware has really helped me understand the basic connections to how something works. A new PC can do so many complicated calculations and has so much data moving every millisecond, that my mind just goes to "and now this software does this". Your channel has helped me to understand more of the basics of how computers work! Thank you for your excellent videos...

It makes me want to start developing my own game. Great work everyone!

[@mayravixx25]

Same. I'm hoping for an MS-DOS version too. I wonder how they'll go about that though. I'm unsure of which storage devices were commonly used with MS-DOS but all I know is that if it's not a 3.5 floppy or CD, I'm screwed :p

[@noarmtim]

This game is so addicting! I bought a broken breadbin 64 and a broken 1541 because of your channel. Just to play this game. Fixed both using your videos and after initial testing, decided it was time to buy planet X2. Couldn't be happier with the purchase(Autograph Box). The box looks so good on the shelf above my desk and there is nothing more satisfying than seeing that game over screen on a victory. Commodore is a good bit before my time but now I am psyched to build another DOS machine like grew up with to play Planet X3. Add this to the hobby list. Keep up the great work!

[@fredrickkay4166]

Have you ever considered doing a tutorial for assembly programs on some of the more popular computers like the C64? If not you should! You clearly have a firm grasp of the hardware and techniques; I'd love for more people to be out there experimenting with and making games on these older computers.

[@The8BitGuy]

I've thought about it. But that's one of those things that I think would only be interesting to a small percentage of my viewers. So I doubt I'll ever fit that into the schedule.

[@ForwardBias]

@The 8-Bit Guy What?? Anything you put out is a good watch! I'm sure a short little introduction to BASIC or something of the sorts would be really interesting to more people than you think :)

[@ETXAlienRobot201]

I will admit being somewhat terrified of Assembly, but I also want to understand it. I'd love seeing some in-depth videos from you covering it. Honestly, you've quite piqued my interest in the C64, especially. (and I haven't yet looked-into programming for it) I feel also that maybe some of the misinformation and basically fear-mongering about programming with assembly could be alleviated if there were more clear and concise information about it out there. You seem more than qualified to provide that kind of information! I cannot speak for all of us, but I'm disappointed sometimes in where you do not go as in-depth as you could. Even here, you could've talked more about the actual code you wrote, specific quirks/limits about the processor, itself. Also, hearing more about a more interesting bug and why it occurred would be entertaining, and perhaps enlightening. I can guarantee you have an audience for this kind of content!

[@khoroshen]

That would be really interesting, even if it is not a full 6502 programming tutorial but maybe just showing the creation of planet X2 more from a technical perspective. Like how you organized the code to manage the complexitiy of a full game project in assembly, how the main loop is structured etc. you wouldn't need to explain it on an opcode level. Would be a great insight for all those people used to todays high level languages, which may not be a small percentage of the viewers. I myself am quite comfortable writing some small routines or simple programs in assembly for 8bit microcontrollers and TI-calculators back in the day, but I have never atempted an assembly project of this size.

I always watch your videos, but never leave a message. This is the first time, I hope you read it. I'm a 33 yrs old Game Developer from Venezuela living in Canada. The first video I watched from you was about a couple of years ago, on how 8-bit graphics were made back in the 80's, it was shared in one of the game dev groups on facebook that I follow, I was impressed by three things: your knowledge, the way you explain things and your lowliness and passion when you share your knowledge. From there, I think I've watched every single video you post. This one in particular made me write this comment because I'm surprised how you manage to dedicate a full year of your life to create a game by your own with such limitations... I really admire you man! Thank you for what you do, you do a great job and you are a role model. Keep it up and if you ever need a developer to help you just write me! I would love to work with you during my spare time (even though I'm not too experienced in assembly, but better with C, C++ and OpenGL)

👍 I watched your speech at PRGE 2017. This seems like an expanded and simplified version - added to favorites.

Yeah, I used that for the basis of this video. However, I was able to add more to it, while reducing the overall length.

[@ILOVESTARK]

Looks fantastic! Just a quick note about the RAM listed on the Amiga 500. It is true that the standard is 512k, but almost everyone with an A500 has a 512k expansion fitted. Making the total 1MB. This is also what almost all games require to run. So if you are planning to do a port for the Commodore Amiga 500, I would suggest to develop with the RAM limit being 1MB.

[@The8BitGuy]

Well, I was also thinking of the Amiga 1000.... but it's probably moot a this point.

[@ILOVESTARK]

The A1000 is pretty rare. Very few actually have one. Its evident in the current Amiga community. Its always a big deal when someone gets one. The A500 is the "c64" of the Amiga range. Its the one most people had back in the day and the cheapest and easiest one to get now. Hell, I have 4 :D

[@Omegakid88]

This is one of the coolest projects I have seen, the fact that you coded the game, made the music and the graphics is amazing and all while trying to stay within the limits of the hardware. It’s like the days of the old game developers when they really had to be creative to make the games that they made. It’s also great to see an older game being made with the knowledge of current game mechanics.

[@NickCharles]

This is absolutely fascinating. As someone who's dabbled in making simple games in Unity before, it's really cool to see how you designed your game around such strict system limitations. It's something we often don't even need to consider today, but it was so important back then to squeeze every last bit of performance and memory out of these systems.

Wow, my kudos to you. People may not appreciate just how much effort goes into writing a game of this level, on a limited spec machine like this. I remember trying to make a game on my C64 back in the 80's, and it was definitely not easy. Coding in assembly language on 6502/6510 is definitely challenging, and I remember having to contend with memory issues and interrupts. But most of all, I'm so impressed with the game concept. If this game existed in the 80's, it definitely would've been one of my favorite.

[@FrazerSmithsChannel]

My favourite video of yours, great achievement on that hardware and really demonstrates how the 'bedroom coder' explosion was even possible.

[@heidirichter]

Fantastic, thank you so much for this look into the development, I really appreciate it. For me, this is where the magic always was - in the limitations and finding ingenious work arounds to fit within the limitations. This is why, for me at least, a large chunk of the magic has now gone, as there aren't really limitations now for people to try to work within on modern platforms. This is why I appreciate this so very much. Personally I'd love to see an Amiga (OCS/ECS, so perhaps 512K Chip, or perhaps 1MB total and single floppy, KS 1.2 and above, 7MHz 68000) and Atari 8-bit versions (130XE or other 128K system), but I can see the appeal of an MS-DOS version with CGA/EGA and 640K.

[@heidirichter]

And yes, I admit to having a strong preference for the Jay Miner systems, LOL

[@KuraIthys]

mmh. I used to own an 800XL, and while I never had one, I was fascinated by Amigas. I only just recently realised how much those two systems look alike in some ways. The Amiga basically is a 16 bit version of the atari 8 bit systems, when you consider some of the design similarities it's almost spooky...

[@heidirichter]

Oh absolutely, and the SIO port on the Atari 8-bits is a direct predecessor to our modern USB, designed by the same person...

What a clever use of banked ram/rom! And how clever of the C64's designers to allow the CPU to write to the ram under the rom and (I assume) automatically read from the rom, without having to fuss, and to allow the video chip to read from that ram! I'm an old Atari guy and they have different sorts of tricks, but yeah, it's good to remember all those clever things we used to have to do with such limited computers.

Fantastic video, one of the best on the channel so far, and TERRIFIC JOB on the game! Just a couple of questions: 1) how much programming/design work has been done on a real C64 VS an Emulator (e.g. VICE). On the latter, text editing for ASM would be easier, of course… 2) Why using a TV with composite when you have a fantastic 1084 monitor, with the Chroma/Luma input?

[@OscarInAsia]

For a DOS port, I would say definitely consider targeting a 286 with EGA and Adlib for sound, as that's the era PC games started really taking off. Anyone with either a retrogaming rig or using DOSbox can meet those requirements. Lots of interesting things can be done in EGA, later Sierra (and other companies) were doing graphics dithering giving (what appeared) to be far more than 16 colors using this method.

[@The8BitGuy]

I plan the first version to work in CGA. Because I want the game to run an an XT. I will then add at least EGA and Tandy support to the final product. Possibly VGA as well, if there appears to be any advantage.

[@4KbShort]

Best part of the entire video was when you were discussing the maps and all the programs you crafted to put them together. I could hear the pride in your voice and it's totally justified. I never had a C64 and don't go back that far in my retro adventures, but this was fun to watch and you did an awesome job.

[@retrotechnerd3124]

Love the video. Wish I could buy a copy, but sadly (as of 11/28/17 circa 10:00 pm cst) all copies are sold out. However, if I must make one comment on the hypothetical MS-DOS port it's the color choice of the CGA color mode. As much as I love your vids & games, I tend to not want to buy a game if it's forced CGA-mode because of the teal & hot pink choice. If it does happen, I hope it's in EGA mode. Best wishes, RetroTechNerd, aspiring retro tech reviewer

[@frechjo]

Ah yes, hate that cga palette. But IIRC, you can define different palettes in CGA? I think you can define *other* 4 colors to use.

[@retrotechnerd3124]

Just so long as my DOS game has more than 2 colors, I'm happy.

[@johnfrancisdoe1563]

fede I think if you run CGA mode on a later style card (EGA, VGA etc.) you can redefine all 4 colors. On CGA hardware there are only a few combinations to choose from. But the game could use well chosen colors on VGA, close approximations on EGA and fall back to one of the CGA palettes on real CGA+clones. This would be simpler than the traditional choice of including code variations for each card generation, but would limit you to 320x200 even on modern hardware.

[@frechjo]

+John, as long as it's not the one with the super bright cyan-magenta-black-white eye raping combination, anything is better. I remember this game called Metal Mutant I had back in my 386, not because of the game, but because of the scars in my retinas. ;)

Man... Paint shop pro! Very interesting video, and I like the fact that even if in these days we have such powerful computers, that simple graphics plus the characteristic music are still loved. I don't define myself as a gamer, but I definitely had more fun on a Gameboy than on a ps4.. Maybe was the age... Nah! Those games were just stimulating your fantasy more.

Beautiful!!! Congratulations David!! Maybe someday I'll aquire a C64 thanks to your passion.

[@machinedgod]

Can't upvote this hard enough. Very inspirational! I am going through the Photon from Scoopex tutorials about Amiga Hardware Programming past weeks. Its great seeing there is a community that is not willing to abandon old machinery. As a long time professional game developer - programming resource-hogging software like games on old machines was just so much more fun!!

[@dbuezas]

Wow great work! My nerd-OCD side can´t stop thinking about the fact that 24k of memory are used by the map :P I would love to know more about how it is stored! The least memory efficient strategy I can think of (a bitmap) would only allow for a 156 by 156 tiles mini map (note 1). I´d gess you used something like an alphabet of unique "structures" (like trees, etc) but still a bitmap (note 2). I`d love to get a map to play with it and see how much I can compress it without a monster algorithm or loosing constant read write times :) I´m thinking of a sparse representation like "trees from tile 23 to tile 30" or something of the sort, maybe even huffman coding (to encode the structure's and different sizes of terrain) for the initial state of the map (with an index for constant time random access) and a sparse representation like a list of coordinates for what changed during gameplay. I bet something should work saving a lot of space for the cool but discarded features. Who knows, maybe it works and it helps the sequel! (note 1) alphabet is 192 unique tiles = 1 byte per tile is plenty. so 24kB = 24576 tiles ≃ 156 x 156 tiles (note 2) assuming an alphabet of 16 structures = 4 bits per structure (a structure would be for example a tank, an alien, a tree, etc) so 24kB = 49152 structures ≃ 221 x 221, from the video it looks that may be the size of the map (?) Anyway, i love your videos!

[@musaran2]

A compressed map still accessible in real-time would be no small fry, especially with that processing power. But note sprites are handled separately, thus don't need to be stored on the map, freeing some symbols. This could be extended to special buildings, or anything rare on the map really. The next step would be procedural enrichment : Store a very simplified terrain (only 8 or even 4 symbols), and have code add at run-time random details (trees, ruins etc). Even further would be full procedural generation of the terrain. But then you need to store any dynamic changes by the player.

Your videos are great!

[@BeyondTheScanlines]

The behind the scenes was great. I've had real life interfere meaning I've not spend enough time with it, but so far, I'm certainly impressed with what you've done on the humble C64! (Plus, the physical aspect of the packaging is top notch indeed. Quite impressed with that. Not to put some more time into it!)

[@henrydave6603]

This was really neat to see ^_^ have to say that's some creative use of memory. Showing this really demonstrates how much work went into a game back then. Heck back in the C64 days there was no Email or other modern computer luxuries. Now I may an old Atari 130XE and not a C64, but would love a copy of this just for that box art! Just looks classic ^_^ Anyways, sweet video! Have to see about getting mine ^_^ Keep up the awesome work man, love this stuff!

Pixel art, you say? To shreds, you say? I'd be up for that! Though, I've never drawn tanks before? I've drawn plenty of science fiction, though. I quickly mocked up a 16x16 4-color tank, using the transparent black, for added detail. The tank treads were shaded in such a way to suggest 3D depth, when moving: i.imgur.com/mEs9PpW.png

and now you get 8 gigs of video memory and 8 gigs of ram and devs are like "optimization? LOL"

mmh. And this is why ports to Nintendo consoles have suffered. 'You mean I have only 4 gigabytes of RAM total!? What!? Forget that! Can't be done!' XD

[@MrDavibu]

You have to consider optimizations costs money and dev-time, they can make a bigger and better game with the that dev-time and that's what many dev-teams prefer.

I think I just learned more about how RAM works by watching this that I did at 2 year of Vo-Tech school

[@cantankerousclankingcontra8295]

While this is an interesting documentary on the "behind the scenes" The narrator does little to discuss the continued allegations of the near slave like conditions for the members of the team. No mention of anyone being forced to work days on end with little food or water. No mention that they denied family visits during crunch time. 8Bit Industries and their shareholders have a lot to answer for. Hopefully 8bit keys is able to offer some outsider perspective into the madness that went into this release.

[@JaredConnell]

I don't think 8 bit guy and 8 bit keys are on speaking terms at the moment 😆

[@PsRohrbaugh]

The vic20 and c64 allow for "feature chips" in addition to ROM on cartridges, correct? It'd be interesting to see you release "Planet x4" as a cartridge-only version that pushes the system to the absolute limits...

[@ThommyofThenn]

Making something specifically for the Amiga is such a neat idea. Love how the Amiga draws colors and all the cool tricks you can use to create the illusion of more colors or detail

[@frazzleface753]

This really is a great achievement, David! Watching you develop your own solutions by writing custom routines and programs is inspiring. Getting a thumbs up for technical achievement from Modern Vintage Gamer is also a great accolade. 😎

[@danielmorrow5267]

I loved it on the c64 but spent most of my time programming, drawing, and composing music on Gary kitchen's game maker so was somewhat exhausted by the time I got shoot em up construction kit.!

[@JesusisJesus]

Yeah, I was hitting High School by then, and they had bigger and badder computers to fuck around with. Like 386's on a LAN. :) And there were girls, with boobs and other squishy bits. I also had a bit of fun with those Demo Makers of the era too. You know the ones where you type and there's music in the background, and you can do all kinds of other shit with them.

[@JesusisJesus]

I spent ages trying to make my own version of Slap Fight, but the real Slap Fight was just so much better, and now that i've got it on MAME, It's hard to look at the c64 version. I was also very good at 1942 and Terra Cresta on the arcade.

[@briero]

I had it on the C64 and Atari ST and I loved it. I spent hours on it and made a few good games.

[@zerphase]

Did you use any of those bit hacking techniques to get more than 16 colors on screen at a time?

[@evilgremlin]

I didn't see it in video. But bithacking is no small code, also timings should be perfect.

[@zerphase]

Evil Gremlin yeah, you might use up too much memory too make the game interactive with improved graphics. From my understanding it's more worth it for vga.

[@AiOinc1]

Doubt it, since it's using text mode.

[@ShaunDreclin]

iirc you could change the text color on the exact right scanline and it would color that line in without changing previous lines in text mode

[@KuraIthys]

VGA brings with it a whole different set of problems. Among which: VGA adapters are dumb as rocks, many of them have video memory that's slow as molasses, and the ISA bus you find on most early cards is even slower. Seriously, if you have an ISA based VGA card, the bus access speed, and resultant CPU wait states are so bad that a 486 is no faster than a 286 for the majority of graphics tasks. There's a reason games like Wolfenstein and Doom started on PC... Part of it is of course that PC's, especially by the end of the 80's and early 90's had very powerful processors. But the other half of it is that EGA/VGA and even many SVGA adapters are so incredibly dumb compared to the graphics hardware in most home micros and consoles, that your best solution 9 times out of 10 is to create a framebuffer in main memory, get your CPU to do 95% of all the work in drawing graphics, then transfer that main memory frame buffer to the graphics card in short, fast bursts. And if the graphics card itself is basically not doing anything other than drawing a framebuffer to a screen, you might as well do really complicated graphics routines on a fast CPU as simpler ones... Of course, that has no real relation to the c64... But I imagine raster effects can be expensive in terms of CPU time and memory use. (not just because the effect takes a lot of CPU power, but because synchronising to the display can eat up a lot of cycles just waiting around for the right moment too.) You see all these really impressive demoscene things, but maybe you wonder why you rarely see this stuff in games? Well... Demos don't really have to do anything else... So they can devote way more memory and CPU time to graphics and sound than most games could ever get away with...

Nice to see the C64 getting lots of love, so sick of NESTube.

[@KuraIthys]

-shrug~ I keep running into people saying how much love their is for the NES and SNES while pushing Sega stuff, but never actually see this 'love' for Nintendo stuff people seem to complain about in all those videos. XD Still, in terms of homebrew, c64 is kinda mainstream. No, the ugly duckling of the homebrew community, the system nobody seems to ever do anything with, is the n64... Consoles inherently get less homebrew than home computers do. (the reason is obvious given home computers always allowed anyone to develop software by design, while consoles were all locked down), but even among consoles some consoles get infinitely more attention than others. And for a system that isn't obscure in and of itself, the n64 is way, way waaaay down the list. Of course, if you're talking about video content, then yes, there are a lot of channels that do videos about NES games compared to c64 or other such things. XD

[@loganjorgensen]

Heh you must be blind and deaf then. ^_^ Nintendo still exists as a console maker and has mainstream appeal so yeah it get's the lion's share of the media content. Atari, Sega, and Commodore have large fan bases but it's hard to gain new fans without a current generation console. Mostly we get mad because the mainstream "thinks" Nintendo invented everything video game related.

[@KuraIthys]

Ah. 'mainstrream' I see the problem already. XD I don't tend to count anything current in the same context as this. I was thinking in terms of 'retro' content. And that's quite a different ballgame entirely. Sega is still around of course. But Commodore is not. Sony has dominated the industry for a good 20 years now... I just get annoyed that people who should know better still make the same inane arguments they did 30 years ago, and parrot whatever stupid crap someone says about things without any thought whatsoever. Such as that whole 'blast processing' thing. Yes, people still bring that up. But then I guess I'm more into the technicalities of these systems than most. It has not particularly been my experience that Nintendo systems particularly dominate in discussions about older systems. Quite the opposite in fact, in many cases. But yes, if you bring mainstream gaming channels into this that mostly handle recent stuff, or a mixture of recent and semi-recent things, then you'll be overwhelmed with Sony, Xbox and Nintendo. Because that's all that's left in the console space, and the home computer space is no longer a thing at all. (so the likes of the Commodore 64, Atari 800, Amiga, Atari ST, ZX Spectrum and all that stuff doesn't just represent companies that are no longer prominent, it represents an entire category of devices that basically isn't really around anymore.)

[@loganjorgensen]

It's not really the same argument, NES is the typical "given" topic in retro gaming, even some European gamers have been having false memories of the NES being a success or loved there because the topic is popular. My best comparison for a Nintendo fan is being a cat person, more crazy than typical pet owners lol. Yeah not many people speak of Nintendo hardware because the biggest fans of it never seem to know how it works in the slightest heh, but it's "mainstream retro" to like Nintendo blindly. It's actually a topic barely scratched with all the helper-chip variety, which itself seems to hinder homebrew. There's not much to say on a technical level about current Microsoft and Sony consoles since they've become generic media boxes so I can appreciate the Switch's uniqueness. Nothing retro is truly prominent, again Nintendo minis got a lion's share of videos.
