Ben Heck's Game Brains Part 1

[@PauloSilva111]

The Ben Heck Show 5:15 this happens because games are not dependent on bios routines (as most of MSX games are) - all Master System and SG-1000 games starts on 0x0000 (Z80 interrupt vectors included in the game rom), so there is no need for bios rom at all, and this also allow Master System games run on SG-1000 Mark-III without problems (unless the game used newer dsp features like 224 or 240 lines)

[@Scanlaid]

Really excited to see this through, great project! Series just keeps getting better :)

[@G1itcher]

God I miss this show. Woefully under appreciated

[@Pawl0solidus]

Hi Ben! Is there any schematic of this project you would share?

[@xanthis5413]

On the Saga Master System, there was a game on the ROM, that was a Maze game. Also the Master System read from either the Cartridge or a Card, so the rom may have done the select between the two.

[@ScarredToons]

Great video! Really looking forward to seeing the rest of the project!

[@TheBrightPixel]

Mr Heck, if anybody ever needed a CNC board router, it's you!

[@fab1604]

This project is gonna be insane! Great job, Ben!

[@dan_loup]

The reason why there are so many similar Z80/TMS9918 systems is due the fact it was the best cost/benefit back then. You had to pick between the Sram chips that were veryexpensive, or the Dram that was (and still is) cheap but required a lot of extra circuitry to refresh it (basically the Dram "forgets" its contents if you don't keep constantly accessing every "block" of memory) and both Z80 and the TMS chips do refresh dram by themselfes. So, if you used em, you could reap the benefits of the cheap dram price, but none of the drawbacks of having the extra circuitry or some fancy memory controller chip.

[@allluckyseven]

Just watched the trailer for the second part (coming out this friday), and I must say that this project is brilliant. And I can't wait for friday.

[@PauloSilva111]

The Ben Heck Show 5:09 don’t forget that Sega SG-1000 Mark-III is a (Japanese) Master System without that bios rom - what that bios rom mostly has is a checksum checker (i think is to avoid running SG-1000 Mark-I and Mark-II games (very similar to ColecoVision and MSX1), so we need to fix the checksum from these games for running on Master System ) - i actually think that Chase-HQ is a Mark-III game that, by default, doesn’t run on Master System because this checksum issue

[@himselfe]

I've been thinking about doing something like this for years, so it's nice to see it being done! Although what I was thinking was an ultimate retro computer that contained both a Z80 and a 6502 so it could emulate the vast majority of 8-bit consoles and home computers, and a modern arm chip to control the system and interface with modern peripherals and media. Instead of using expansion boards to configure which system it emulated, you could either emulate the custom chips on the arm chip, or to keep it retro use a 68k to emulate the custom chips! Alternatively, another project I've considered is a 'Retro Shield' for the Pi, that has a Z80 and a 6502 and perhaps a 68k to 'accelerate' emulators running on the Pi.

[@Scribblersys]

Connecticut Leather Company, not Colorado.

[@G00DwillHUNT3R]

Sizik I was going to say something about that too, but I knew someone else would have caught that :)

[@cooliofoolio]

***** nice icon

[@APOTwixx]

Same thing I was going to say!

[@patrick74161]

Sizik Being a Nutmeger, I Felt the same way. At Least He didn't say California! XD (Nice Icon G00DwillHUNT3R)

[@BrightSpark]

Oh, since the Master System's Z80 is also used in the Megadrive/Genesis for backwards compatibility and sound output, would it be possible to make a Megadrive Add-on for the Master System that contains most of the Megadrive' guts? You might have to use a seperate cartrige slot and probably use a seperate video output for the Megadrive-portion, but would it be able to get the Genesis working when hooked up to the Master System?

[@tfraiseo]

Really cool project! Can't wait to see more on this one.

[@mirabilis]

I miss Allison. :'(

[@josephmarlin9827]

mirabilis I wish we could have her AND Max

[@allluckyseven]

Joseph Marlin AND Felix. And NO BEN! (heh, j/k.)

[@D3ltaLabs]

I love these types of video tuts.. I'm not sure if you have thought of it but it would be good to have a ebook, with more details on the process Etc to complement your video.. Thumbs up on the hard work you all put into these videos. Thanks :)

[@rdoetjes]

I'm confused here. Did the editor renumber the addresses after pasting it In? Because a long Jump (jmp) contains the final calculated address after macro assembler is done its work. So in order for the one bios that has been moved from low address to high address all absolute addresses for jumps need to be offset. Which means the editor needs to understand the mnemonics of z80.

[@RetroDawn]

No need, since this was just using A13 for bank-switching two 8KB banks. So both 8KB "BIOS'es" are both starting at the standard address they're mapped into.

[@RobertNES816]

So Ben would you be able to include the original Gameboy hardware into this build? I believe the Gameboy used a modified version of the Z80 processor.

[@DAVIDGREGORYKERR]

This is odd as I would have thought that it would need to access ROM for some routines that cannot be built into the ROM cartridges BTW the third system could be a Sinclair Spectrum.

[@treypop123]

would it be possible to do something like this with the Super Nintendo and the Sega Genesis?

[@loganjorgensen]

Great idea, always curious if consoles with the same "off the shelf" parts could coexist in one box. :)

[@marciolimas]

Is it possible to, today, I buy these chips an build mine mutant console? It's possible to buy some chips to build a cartridge that I could put roms on it?

[@shinji391]

What's the name of the ending theme song?

[@BrightSpark]

The "weird" ROM behavior was probably because of SEGA also selling some Master Systems with built-in games, for example I had a Master System II with the 8-Bit version of Sonic 1 built-in as a kid. Maybe SEGA stored the game on the same ROM chip as the BIOS on those units...?

[@matthehat]

Bright Spark In the master systems with games built in the games are on a separate ROM chip. I swapped Alex the Kid for Sonic Chaos in mine - because why not?

[@cakestalker]

Bright Spark Nah, those units does not have a BIOS screen to my knowledge.. Not that you could get it to show unless you hacked it and disabled the built-in game. Here in Europe where I live Master System II with either Alex Kidd or Sonic built-in, was way more common than the original model. I don't think I have ever even seen the original model in real life, but I lived in a small town so :P

[@szymon1051]

More frame in electronic14 intro?

[@FilippovM]

What is the RAM chip?

[@mduke2k]

I thought the Master System has a built in game, I believe it is a maze game. Ben mentioned that the system ROM detects if there is a cartridge installed and then boots the game ROM. I wonder if that's why Sega did it that way.

[@delvontamenyweathers4303]

Is it possible to make a fully upgradeable laptop?

[@Jeffball610]

I'm always curious why you don't make circuit boards for these projects instead of hand wiring everything. The only thing I can think of is for trouble shooting if you miswired something. The circuit boards would be cleaner and likely be faster than wiring up something by hand.

[@DavidGriffithsTweetUwrite]

Jeffrey Ball they want to show people who dont make circuit boards how its done.

[@Jeffball610]

***** I'm not sure that's true. He's modifying components that were originally made for circuit boards. He also has the ability to use modern components (which he uses in other projects) but they won't make boards? "We have the technology..." I just think it would be cleaner, simpler, and faster. Again, the only reason I could see going this route is for trouble shooting. But even a circuit trace could be cut and a wire spliced in if necessary.

[@jokerlover300]

Hi could you possibly do a build for a ps2 slim portable with disc drive?

[@cakestalker]

Master System II has no boot-screen to my knowledge, but that may be because they came with a game built-in (either Alex Kidd: In Miracle World or Sonic The Hedgehog). Maybe they had that extra rom to be present cause they later planned to have games built-in for the newer model? Strangely enough I hear the second model is kinda rare in the U.S.. maybe because since it was never a big success there as it was here in Europe (and South America). Here in Europe the first model is actually a lot more uncommon than the second smaller model! Just some random trivia for those who care :P

[@awesomefai2798]

I know that you just started a new project, but after this could you do a nintendo gamecube portable?

[@Gametherapist]

Here's an idea I have but I have no way to make it work, sadly: Combine the processor of: N64, SNES, Sega Master System and Atari Put on 256MB of RAM. Everything on a breadboard, but with fast data lanes, like PCI. That would be an amazing system to play with 2 usb ports like a Raspberry Pi

[@top5cz794]

Hi Ben, which wire do you use to solder pcb?

[@LesterRamirez]

Hi Ben!! can you resurrect the old Capcom Power Stick Fighter via USB trough arduino uno??

[@KDP2009]

hey ben! would you ever do a project on making a custom flash cartridge for gameboy and gameboy color that can play most games, and a custom programmer for the cartridge! :D i would love a tutorial on that. im super interested on gameboy flash carts but i cant figure out how to build a flash cart and programmer with chips and parts that are actually available for purchase these days.

[@Kostos2222]

doesn't the gameboy have z80 ?

[@Crux161]

Is there a chance you guys might ever make an old school serial terminal like a vt100? Maybe with an lcd instead of the old crts' -- or maybe TV (composite) out? Lol that'd be so neat.. And I've been really needing a serial terminal, but they're not the cheapest thing right now :\ This would be a great idea for possibly hooking up to a raspberry pi..

[@SnowyPup]

this is another difrent type of combo system, basicly you have a computer with a xbox and PS3 and normal computer parts and hook them up so an emulator looking program can boot up the system, and use your computer's keyboard//mouse as a controller

[@dandragonmc]

Ben can you show us a play station 3 or play station 4 portble

[@pokey4200]

Awesome idea Ben! I like that programmer you have.. what kind was it again?

[@Alfiewow]

I only tuned in to see Felix and Max's heads sewn together. 1/10. Very let down.

[@jorenmartijn]

Ben, you'd be awesome if you could incorporate another system, but I'm not sure if it's doable: From Wikipedia: Nintendo's Game Boy and Game Boy Color handheld game systems used an 8080-derived processor with some Z80 instructions added (CB prefix) as well as unique auto-increment/decrement addressing modes. The CPU was a Sharp Corporation LR35902[65] running at 4.19 MHz in the original and Pocket models, and 8 MHz in the Color model. This processor was later included in the Game Boy Advance / SP / Micro taking up a new role as a co-processor for backwards compatibility with Game Boy / Color games (except Micro) and to add legacy 8-bit sounds to supplement the digital samples in Game Boy Advance games.

[@tetsujin_144]

jorenmartijn It gets tricky with some of these old systems that use _similar_ CPUs. Like the 6510 from the C64 and the 2A03 from the NES are both based on the 6502, but with some differences, like the sound built in to the 2A03 or the extra I/O lines on the 6510. All these CPUs also support some undocumented opcodes which *are* found in some actual production software as well. The Game Boy's Z80 is a similar situation; it is neither exactly a Z80 or an 8080.

[@brandon-butler]

Where does one learn how to build a computer like this?

[@mllarson]

Brandon Butler Pick up a copy of "The Black Art of Video Game Console Design" by Andre LaMothe on Amazon (or wherever you can find it). Should tell you everything you need to know.

[@josephmarlin9827]

Brandon Butler See the other guy, but go see if you can get some back copies of any of the old TAB publishing literature on designing 8 and 16-bit home computers. Grew up with a copy of The Microcomputer Builder's Bible ( www.amazon.com/microcomputer-builders-bible-Chris-Johnston/dp/0830624732 ) in the house as well as their fantastic Z80 programmer's manual and Z80 bugbook and those are what got me into this stuff in the first place. You'll find that a large portion of the support chips listed in the Microcomputer Builder's Bible are still manufactured, though not so much most of the memory chips. But you can pretty much use way faster modern SRAMs as drop-in replacements. Digital circuit design using big blocks like RAMs, ROMs and CPUs is surprisingly easy, once you know the basics! Just look up the datasheets and wire together the pins that need to talk, really. Also on The Ben Heck Show :P

[@josephmarlin9827]

Brandon Butler Ohh, I just remembered another awesome one I had back in the day that you should check out: www.amazon.com/How-Build-Your-Working-Microcomputer/dp/0830696849/ref=pd_sim_14_8?ie=UTF8&refRID=1K2VCV6XTANNZBEA1KQX Get 'em both. Trust me, if nothing else they're wonderful bathroom reading. I'd say I learned most of what I know just by virtue of having these stashed on the tank for years.

[@derpmansderpyskin]

Do you think you could maybe make a internet enabled Atari 2600? Maybe have a box that transmits video, and receives controller inputs, then have another box that receives video, and transmits controller inputs. Have them communicate over the internet and you have an internet enabled atarti!

[@resystanc3]

I can't wait for next episode. :)

[@kampaclassic]

The Ben Heck Show ***** Small note: It was Connecticut Leather Company as opposed to Colorado.

[@jarboer]

How do I do +"name" it never works can u tell me what to do? Someone

[@chici2000]

Jarrett Boersen you just need to click reply on the comment that you want to reply to. then it adds the name automatically

[@jarboer]

Ok but what if I'm not replying to that comment and I want to say +sethbling

[@chici2000]

It's really Simple, you if you are in Chrome (idk if or how it works in other browsers) you just need to write the + and the start of the name like SethBling (prntscr.com/7jihz1) and then you just click on the name of the user that you want to add to your comment.

[@anrysnail]

could you try make a wrist mounted computer like the pip-boy 3000 from the fallout games? as another project please?

[@xanokothe]

Soo... A PC with console emulators?

[@MyCrazyGarage]

This has to be the 3rd time he wanted to use coloured wires. This feels like watching the same video over and over again. (Doesn't mean its boring)

[@SenorSquilliam]

Please make a combination genesis 32x

[@FlexxVision]

You are the Magic! Best regards Karsten.

[@FantomZap]

Were you using the word simular in place of similar as a pun? If so, its a very intelligent use of the word. If not, maybe this comment might point it out to you.

[@TheMBB99]

Very nice part! When I read the title, i thought you programm an AI for solving games itself :D

[@DavidGriffithsTweetUwrite]

The Ben Heck Show Maxafelix - lol i nearly fell off my world with laughter :)

[@ScottBeebiWan]

***** dafuq u talkin bout

[@ScottBeebiWan]

The Ben Heck Show I believe that you should do a zx81 portable. My dad made one in this process: 9v battery clip connected to headphone jack (power supply) battery powered b&w tv (screen) and the zx and TV connected together. You could base it on that if you did it.

[@element14presents]

Scott Blacklock Getting hold of zx spectrums is a little difficult - suddenly they're very sought after!

[@tetsujin_144]

Nice concept!

[@Tron08]

It's amazing how many KZbinrs I watch that say, "never do this thing I'm about to do right now" lol

[@downtownriders7288]

Ok you should try doing thhis with a ps1-2-3 andxbox,360,1 you could flash the dvd drives so they can play all and use one of the gamesystems cpu and gpu so it is smaller and better somthing like that

[@1903tx]

Ben, I hope all those PCBs you stripped for parts were from eight-liners, redemption games, or something like that. I'd hate to think you killed a bunch of classics.

[@MAYERMAKES]

the titles and the channel logo interlace ....xyou should fix that by moving the channel -logo up

[@NoorquackerInd]

If you get all the EPROMs and EEPROMs you have, how much memory do you have? You never know, you might be able to store Crysis 3!

[@shadfurman]

You ripped out its ROM while it was running? And combining brains is horrible?!!! Reminds me of when I found I could hot swap hard drives of the same model, people wouldn't believe it even after seeing it. How do you know it's not being written to when you pull it? Luck.

[@shorthouse06]

ROM stands for Read Only Memory, it can't be written to.

[@shadfurman]

Please stop doing the suitcase zoom in effect. It effectively reduces my comprehension when its done especially since its normal in very technical areas where it would be much nicer to see the items Ben is actually pointing to. I also normally watch the videos on my phone and it reduces the overall video six on the parts. I'm interested in seeing how the project turns out, though!
