You know what? This concept would work really well on a modern game as well. I'm almost imagining a current gen game where you'd enter a robot factory and had to eliminate robots and solve puzzles in order to reach the next level. Solid concept and looking forward to it!

[@MontieMongoose]

I love that you made the difficulty setting makes the robot more angry. Reminds me of the difficulty settings in Wolfenstein3D and Doom.

[@The8BitGuy]

Indeed.. That is where I got the inspiration, only it's backwards because it is showing the enemy's face instead of the player.

[@LaskyLabs]

As soon as you have an idea for a game, you've got a prototype ready within seconds. It's genuinely amazing how with old, simple computers like this, you're making the game as you're working on the concept. Nowadays you want to think on a game for months, then do simple demos... Then years later it's done. But this will be done in what... A year? Two? Not only because you're skilled, but because it's simple. The better games got, the more points of failure.

[@baroncalamityplus]

Hello, please reconsider reimplementing the shift+wasd for movement and shoot. I don't have the use of two hands and that would be a great accessibility option. Thanks.

[@ericjianuzzi3448]

How do you game with one hand? When I radially dislocated my wrist I relearned to hold my controller and managed to push buttons with my ring and pinkie finger but I did have at least that. I'm very curious about true one handed gaming. I am aware a keyboard may have advantages but I assume there's also unique challenges by comparison to a controller.

As a modern programmer, I feel like we are missing something nowadays. I feel like your program that is "closer to the metal" has a feeling to it that you dont get any more. I was writing in python while watching this and I wish we had some of the feelings back if that makes sense.

I'd suggest remapping movement to "IJKL" instead of "PL()", as that's what many games already use when there's no numpad available.

[@SamiKankaristo]

And if you're playing the game on an emulator, you might have keyboard layout issues with ( and ), they're under Shift+8 and Shift+9 on my layout...

[@Keavon]

Exactly, WASD is the standard set of directional keys and IJKL is the standard secondary set. I'd also recommend using WASD for movement and IJKL for shooting, rather than the reverse, since that's more expected as a standard.

[@TheAio]

also () won't work on most nordic keyboards

[@deanolium]

With this setup it then makes sense to then use the number pad for firing, otherwise it’ll get uncomfortable

[@SamiKankaristo]

@@deanolium "Tenkeyless" keyboards are pretty common these days, so a number pad might not be available. WASD+IJKL would be a "safe" default layout, since those keys are in the same positions on all keyboards. (Unless you're not even on a QWERTY layout, but then you're probably used to keyboard layout issues in games, and the keyboard config is the first place where you always go).

Back in 83-84 I made C64 board game called Drunken Bum. The object of the game is the Bum travels the board to collect bottles and scrap that he can redeem at appropriate board locations, but there were challenges to that redemption along the way. There was a full simple board layout and the spaces you landed on expanded to show a specific action for that space. For example, if the Bum had collected any bottles, he would lose a randomly generated number of them if he landed on scrapyard and received the "guard dogs find you" random result instead of the "find 1 lb of copper pipe". Other pitfalls were landing on a space with police and they take you to the dunk tank and a fine is taken from you. Eventually, you ended up with enough money to go to the liquor store for a bottle of whiskey and the game ended. I had that game saved on a cassette until the 90's, when my younger brother used it for a mix tape.

[@scottwilliams895]

No kidding, you are BRILLIANT! I love to see what you're up to. I don't have any of the old computers you do, and being a few years younger, pretty much never have used them. I also have very limited (computer) gaming experience. Still always love to watch The 8-Bit Guy!

[@brianh2771]

Looks really cool. Love the portability. What about color 80-column mode for the C128? There are a heck of a lot more C128's than there are 80-column PETs or B128s, and it would have the highest color resolution of any of the Commodore platforms. Plus the C128 has independent cursor keys AND numeric keypad AND a SID chip.

[@TB-td6fx]

Brian H And 2Mhz in 80 col mode 😃👍

[@MartinAncher]

That was exactly the question I had. 🙂

[@javiergonzalez7104]

But the video chip for the 80 column screen, the VDC, doesn't share with the CPU the memory mapping like the other 8-bit CBM platforms do. The 8bg would need to rewrite the scroll routines and so, and I don't think there's many people out there with VDC programmings skills to help out.

[@MattKasdorf]

Please add CB2 sound to the PET versions, possibly as a small addition the the SNES User Port card.

[@BalugaWhale37]

I had no idea the PET had any sound at all, but a quick web search shows that the user community had discovered sound was available out of the CB2 pin on the cassette port in 1978. I guess this would chew up some CPU resources. If adding the resistor, headphone jack and piezo speaker parts are too costly, perhaps the PCB could just have the traces with NOPOP options on the components.

[@mrmimeisfunny]

Maybe David could use CB2 sound on all systems if the SNES card is bundled with the game. I hope if it does he uses an aux/composite port instead of a piezo speaker.

[@nuk1964]

​@@BalugaWhale37 I remember my jaw dropping when I heard the digital samples audio coming out of the Apple ][ speaker with Castle Wolfenstein -- pretty impressive considering it was done with a "push-pull" interface (e.g. you send 0s and 1s to control port to vibrate the speaker) I also remember the method of getting audio from the TRS-80 Model I by sending 0s and 1s to the cassette interface. A portable AM radio could be placed near the cassette port to pick up the RF interference from the circuitry. A better solution was to get a mini-amplifier/speaker and connect that to the cassette audio connector. Of course in BASIC the best you could achieve for audio was a low-frequency buzzing noise.

[@makipri]

Eric Hollas Later models have an inbuilt piezo speaker connected to the timer2 interrupt. And you can play back samples through that as well. Check my demo OOBC: We are computers.

So brilliant! Your imagination and the drive to improve, try something new, are admirable. I regret giving up on programming on C64 after my first failure, at age 9 or so. Didn't really pick it up till my thirties on PC. That said, I did enjoy my C64 a lot in a creative way, nonetheless. I loved doing weird little drawings of cartoon characters, right on the prompt screen. Text mode offered some cool possibilities, too. I might be remembering it wrong, but wasn't there a key that upon pressing changed whatever you typed in into an alternative set of characters/glyphs.

[@drcemdede]

These explanations really help me understand the "why" questions I had years ago when playing games on these computers. Thank you!

[@thecaveofthedead]

I think that by using the PET characterset, you've created a unique retro-nostalgic aesthetic that looks amazing and will very much satisfy C64 users IMO.

[@charlesjmouse]

Awesome! Just a (very) small thought - sound: As the non-PET versions are intended to be "flavors" of the base game rather than out and out "improvements" maybe that can be leveraged as a "feature" for the sound in all versions... ...write the best sound effects and music you can manage for the PET, it always amazes me what can be done with a computer that doesn't actually have any sound hardware! The other versions would use the exact same data, played the same way, with a little code to "emulate" the PET's beeper where a direct port won't work... ...yes the SID or TED would be virtually unused but as this game is all about "How awesome can I make a game on the PET?" ...and here's versions for people without PETs, that may add some charm. If people really, really, moan then maybe a rudimentary tracker player from the main menu on the systems than can handle it to play one's own tunes might be fun,.

[@shiru8bit]

This is kinda the plan, although VIC-20 does not really have resources to emulate PET sound close enough, so it will sound different. You can check out what is going on the technical side of the sound code development here: tinyurl.com/y6d6c5n7

The Legend of Zelda: PET of the wild Instead of compositing tiles and sprites into an offscreen buffer, why not composite the sprites as you draw the tiles? You could probably make this efficient by keeping track of a list of the start addresses of each span of visible sprite data (stored in ascending order), and every time you hit the next address in the list, draw the row of sprite instead of the next couple of tiles, and advance the “next sprite address” pointer.

I have actually considered a method similar to this. I'm still thinking about it. The trick is, as you guessed, not to take too much CPU time between tiles trying to figure out what to draw.

​@@The8BitGuy Instead of having a 1000-byte character buffer, you could work everything on the tile buffer that has the size of the amount of tiles on screen, which I guess is 77 bytes. Prepare the 77 bytes with the map information, then overwrite it with "sprite" tile numbers based on their coordinates. Only then draw the screengraphics based on the tile buffer which will do everything in one go. This can be done as I'm seeing the "sprites" are always fixed to the tile boundaries, effectively making the sprites just tile variants. This is the way Ultima games work. However if your background tiles and sprite tiles together exceed 256 variants, then you may have to rethink the tile buffer.

@@zygocact5947 It was because of the environmental setup puzzles and also wanting to make a pun on the PET. Calm down.

[@PaleozoicPCs]

@@The8BitGuy I thought I saw someone mention this in a comment yesterday but I can't find it today, so I'll bring it up again. I'm pretty sure the PET has a 60hz interrupt that fires when the machine enters the vertical blanking area. I'm curious if you're timing your screen updates to track that or just doing them asynchronously. It probably doesn't matter on most PETs because I think all models since the "Dynamic Board" have their video set up so it's fully synced with the 6502's duty cycle and non-conflicting, but I believe on the original models with very slow video RAM you can get "snow" if you update when the raster is in the active area.

[@fluffycritter]

@@zygocact5947 I am not saying that at all. Just that I was reminded of it. There's more than one game that does the same thing. It's okay for people to like different things than you.

You are my hero. Making software for these old designs is amazing. Coding for these primitive machines takes a lot more thought that for more modern computers.

There are many people with alot of knowledge about these old technologies, but very few share theirs. Thanks for sharing!

It’s been three weeks since the last video. Hope David is in good health

[@Elomentoplayz]

He probably not doing well his last video got alot of backlash and the comments where turned of because of that. He broke broke a VERY VERY rare pc. Shorted the pc out and it broke he didn't have enough time to fix it but he spent way more time on the more popular pcs. there is only 50-60 of those pcs and it almost hurt to watch that video. He should of spent more time fixing that pc it would be much better if he delayed the video 2 weeks and properly fixed it. It would make a much better video and he would of avoided those whole mess. We wouldn't of cared if he accidentally broke the commodore 64. Alot of fans unsubscribed and got very disappointed by that video like me. That's why I stopped watching for awhile. go to the wayback machine to see what what I mean.

[@guayabito6946]

@@Elomentoplayz Yeah that was appalling. I can't believe he did that. Then he tried to sweep it under the rug by disabling the comments. That was horrible.

[@guayabito6946]

@@Moffstarr To him it was probably a crappy old PC because he has so many. But and IBM prototype of which there are only 60 in existence is not just some "crappy old pc". What he did was inexcusable.

[@Elomentoplayz]

@@Moffstarr i know it wasn't that bad or I would of left completely never thinking about it again. But, he just broke a really rare pc but that still hurt to watch. I'm very interested in pcs and trusted him with these videos alot and when he made that video it was way more disappointing because he fixed many other old pcs that were much more common and to more time to fix them properly.

i'd like to suggest you swap the movement and firing keys. wasd for movement is so universal in modern gaming, it would be much more natural for most people if your control scheme followed that.

[@SamiKankaristo]

Was thinking of this as well, WASD is so common for movement (for a modern gamer at least).

[@joshuavincent7884]

he said he'd do user-customizable controls so...

[@TheYaMeZ]

I agree. Most twin stick shooters/FPS will have left stick as movement, right stick for aiming.

[@Danny.._]

@@joshuavincent7884 even if they're customizable, it still makes more sense to have the default be the one that makes the most sense to the most people, to reduce confusion/frustration.

[@FriedOrange]

As someone used to playing old-school Windows games with the arrow keys (games that were made long before WASD was popular) I do like the current control scheme though. In any case, user-definable controls would be the way to go

[@NathanCorleone]

I love these logic based games, your doing great stuff David!

[@TheRealShedLife]

I'm at 12:58 and telling all my middle-aged friends how awesome this is and your page. This is absolutely fascinating. Grew up programming C64, and hearing you explain stuff and show it - when I was programming, we had no money, so there was little way to get much information. I wish videos like this had existed back then lol but then again I am so happy about the mounting uptick in interest for programming on 6502 8 bit, C64 among others. I think a lot of guys a little younger than me are interested in programming on the Commodore 64 because they all had Nintendos., And they know that's the same processor, and programming on a C64 is certainly cheaper than a Nintendo devkit.

[@FeelingShred]

Duuuuuuude !!! It's amazing how these simple ASCII graphics instantly fascinate me more than any modern 3D game out there.

[@FabledGentleman]

Can i suggest something? Maybe Matt Gray could be interested in making a SID tune for the game, if he gets some good will going the other way. He has had 4 successful Kickstarters for making remixes of C64 tunes over the past years. So yeah, he is most definitively active. For those who doesn't know, he is the one who made the soundtrack for Last Ninja 2, one of the best C64 soundtracks ever made.

[@FabledGentleman]

He is doing some of the best remixes of the c64, i will link one here: Last Ninja 2 Central Park In Game kzbin.info/www/bejne/nYimdmWBeM-tbqM

[@The8BitGuy]

Well, I'm open for anyone right now. But I can't afford to pay somebody a fortune.

[@FabledGentleman]

@@The8BitGuy What i was thinking, and this is just me thinking. You do have over 1 million subscribers, and he is making money on his kickstarters and selling his remixes and other music. If it isn't too much of a hassle for him, he could maybe gain a few more sales making the game music if you help him back, with links and stuff. This is just me thinking out loud, was the first thing i thought of when i heard you mention SID music xD. I mean, i love both your videos and Matt Grays music, so for me this would be a boombastic collaboration xD. I could send him a message i guess, and link this comment. Can't hurt i guess.

Surely Anders Jenson would be able to create something for you as a friend of the channel... or... a tune by another friend of the channel, Christian Simpson (Perifractic) has done some very good music too!

[@EdwinSteiner]

You're really good at software. This almost gets lost among the many hardware-focused videos you do. I could see you doing a very interesting series of videos about 8-bit-specific programming. Just go easy on those spoilers! Don't let your enthusiasm for the new game make you spoil it too much for the potential buyers.
