To dump the bootrom/bios from the final retail GBC, a hardware modification technique called Clock Glitching was used. The system clock was briefly made to run much faster, causing the CPU's program counter (PC) to glitch outside of the bootrom area, and begin executing code from the cartridge instead. Normally the bootrom removes itself from the memory map, and is not readable when running code from the cartridge. But glitching the program counter (PC) into the cartridge area causes the bootrom to remain mapped in memory and be readable. From there, the program on the cartridge would copy the Bootrom contents into the save memory on the cartridge, then you could back up the save memory.

I heard recently that its possible to create gameboy roms in a similar way. By crashing a gameboy and waiting around 20 minutes the game cartridge's data begins to "leak" in such a way that it is played as raw audio. By getting a good recording of the gameboy speaker's beeps, it is possible to reconstruct a full rom of whatever game is in the system.

The contacts above the CPU are a footprint for a zero insertion force socket - this board has been likely used to qualify pre production multi project wafer test runs of the CPU and these sockets allow to switch between samples without soldering. The soldered on chip without the markings is likely also a pre mass production version and some of the glitches you see in more modern games might be hardware issues fixed in later retail versions of the processor.

The early GBA and even 3DS development kits were large PCBs from Nintendo, created by Intelligent Systems. With the GBA the amount of RAM was a lot smaller. When Nintendo got spooked with the rumours that Sony was entering the market with PSP they replaced it with a new PCB with a larger RAM. With all the prototypes we had to send them back to Nintendo. They replaced them with regular IS systems. The 3DS PCB even had the two screes on the PCB.

The NVC-VUE is a custom tweaked version of NEC v810 CPU. If I had to guess why it was on that board, I'd edge towards it being used as a coprocessor for handling the debug harness. Edit: From a little research the SCSI controller is an NEC chip, which requires a NEC CPU to be run in tandem

@lilkitsune 4 месяца назад

Also the nvc 810 had been used in the snes development kit so I assume Nintendo already had debug tools to work with it (memory seeks/mapper and the likes). Also the predecessor of the v810 were commonly used in dev kits to implement stuff like lockstep and this could function as one when paired with the attached gbc dev kit

We actually had one when we were doing one of the early GBC games (Quest for Camelot) for Nintendo US. The one we had was a bit different though (the screen was in the middle of the board as far i remember, but that was last century so my memory might be fuzzy here). They sent us the actual devkit afterwards but i'm pretty sure they never asked for the early kit to be sent back.

Worth mentioning for viewers before misunderstandings spread: the FPGA inside is not at all doing the same job as what's in a MiSTer or Pocket. The CGB "EMULATOR" is only emulating the cartridge itself. The probe is basically just a long extension cable you could plug into any Gameboy, which is why it worked with the prototype GBC. Hell you could use it with a Super-Gameboy or Gameboy Player! The CGB-CAPTURE however, is it's own standalone thing with video output and a dummy system as a "controller".

I doubt the glitches are from firmware incompatibility. The firmware is really only present during booting to verify the ROM header and display the logo. After that, it's no longer present in memory space at all. There's no BIOS or OS, games talk directly to the registers inside the CPU. My theory is that either something in the chip itself changed, or that on this revision there was an issue with the LCD not being able to handle the faster clock timings of 8MHZ mode. Try playing a game that is compatible with both CGB and DMG, those typically leave the system in 4MHZ mode, even when running on a CGB.

You must look at the two devices separate. One is software development and the other was BIOS and hardware development. on the H/W board Connector US2 is the BIOS chip and you can dump and write a current GB bios , but do take note that within the bios is the code that controls the lcd (initital setup etc) and games use that to work , some coders included their own code instead of using the bios and thats where your LCD issue comes in, if you check the lcd on that board you will see it has different timings to a factory retail lcd. On the Software box the ram was changeable so it could support newer models even though they not been designed yet and also gimp you on features(upsell whats already there) , some units could just emulate carts and others would do a form of dual access ram giving you full debug of real time memory.

I would hesitate to call the boot code on the CGB a "BIOS" or a "Firmware". It's more of an initialization routine and signature check. Very short in length and hidden from sight as soon as the code on the cartridge starts running.

The featured PCB is probably more for devs working on launch titles. I did a bit of GBC testing around then, and we mostly used flash cartridges. We also had a N64 with a GBC emulator for testing on a TV, although it wasn't trusted as much as the regular hardware due to occasional differences that crop up with emulators.

some of the features of the bootrom seem to align with a early document leaked in the gigaleak. the version listed happens to also allow you to open up a pallet selector similar to the super gameboy. according to the document, you accsess the menu by pressing A+B+Select+Start. if you get a chance, please test it out. and please dump the bios, it is possible and it will probably be done in a way similar to what was done for the final Gameboy color.

I had no idea what a GPU was and he showed me a GeForce 4 card making my games play better after putting it in my pc. I was the son he wanted but had to barrow from my uninterested parents.

There's something really charming about them using SNES power supplies for this. It was probably more because the power supply was quite generic (my SNES supply died ages ago and I have been using an non-specific supply I picked up in a random electrical retailer since) but them keeping it 'in the family', much like with the Virtual Boy chip there, is very much in keeping with the 'new things with outdated technology' ethos that gave us the Game Boy in the first place.

Nit pick about the IS-CGB-EMULATOR : "This device uses a Super Nintendo power supply." The jack is for a Famicom and Super Famicom power supply, the SNES connector is different. The CGB-STB-X2 of course uses a Super Nintendo power supply as stated. The CGB-STB-X2 cannot use a Super Nintendo pad on connector P9 unless you want to bypass the controller's shift register IC and wire buttons in directly. I wonder if the main chip may be faulty or has a less than complete GBC implementation, which might explain the board's relatively clean state.

@joemck85 3 месяца назад

The compatibility issues are because of hardware differences, not firmware. The only firmware in a GB or GBC is the bootloader. It's a 256 byte piece of code that's burned into the CPU when that part is manufactured. All it does it display the logo animation, load the Nintendo logo from the cartridge, display it and check if it's the correct logo data. If it is, it fully disables access to the bootloader code and turns full control of the hardware over to the game cartridge. For the GBC, it also checks if the cartridge is GBC-enhanced/exclusive. If it isn't, it puts the hardware into GB compatibility mode and lets you change the color palette if you push buttons during the logo screen. Since GBC games mostly work just fine on that board apart from the graphical issues, I would guess the hardware incompatibility is in the PPU -- GPU basically but it processes sprites and background tiles rather than polygons and shaders. Most other incompatibilities, I would expect to see the game run at half speed, have many of the graphical elements replaced by garbled Missingno-looking boxes, announce that it only runs on GBC (in the case of Crystal), or most likely crash very quickly like when you select the wrong MBC. This would also explain why non-GBC-enhanced games run better -- the GBC PPU has two modes that behave differently, one legacy mode that replicates the old Gameboy PPU, and one that has some tweaks and enhancements beyond just the addition of color. So most likely they made some late revision to the PPU between making that dev board and making the final design. Also, I would guess that dev board is probably for internal use by the team and partner companies designing the GBC hardware itself, not for developing games to run on it. Features like unpopulated holes in the board where you can add debug probes or solder in wires to connect a controller, are something you'd give a hardware dev, not a software dev. Software devs are scared of soldering irons and leery of exposed ESD-sensitive circuit boards. They also need something that connects to a PC for debugging and controls using an actual GBC to see how the game feels on real hardware.

If I recall it went something like, you wire up the address, data, and some modified clock lines from some accessible address space (WRAM/ROM or something) and I think all the address accesses would show up there as the CPU executed, with exception of if the address space was within the actual IROM space, and then since you can now externally control the clock, you then tick the clock and count the clock cycles and wait for the lockout register address to show up on the address lines where it goes to write to some internal register to disable the IROM access, and that address I believe still shows up on the address lines (I could be wrong) and then now knowing how many clock cycles into the boot process the lockout register write happens, you do the process again, only this time now knowing how many instructions you have to clock in before you get to the clock cycle that executes the instruction to write to the lockout register, you then do a very quick extreme overclock at that exact moment to glitch the CPU to NOT execute the actual lockout register write instruction, which then will eventually fall into user controlled code on the cart with the BIOS still actively able to be read out. I'd almost be sure it could be achieved today more easily with a RPI Pico.

what a cool prototype. Didn't think anyone would see prototype hardware that's this early in development

Nice, so we can make a Gameboy XXL Maxi in future? 😆

That NVC-VUE chip is a VRAM chip. The same one is used in the Virtual Boy because internally they are basically the same as a GBC, the 3D effect is just a mirror trick.

Given that one of the debugging units uses a retail board, can you hook up the cartridge plug from the emulator to a retail Game Boy Color?

If it is possible to dump the firmware of the big prototype board, do it, and upload it online, as it would be interesting to have this unique firmware available to use and tinker with.

@ifrit05 4 месяца назад

NVC-VUE is a modified NEC V810 CPU. I think it's being repurposed here as a general purpose microcontroller. (SCSI stuff perhaps?)

The music in the background on 4:20ish is from a video game, right? It's in my head, but I can't work out where it's from.

This hardware, or at least the idea of it is in the film “Tetris” on Apple TV, I had assumed that it was an over the top idea but I guess it’s nice to see it did exist

I wonder if there's a BIOS update out there somewhere that could potentially fix the issues with newer Gameboy Color game and/or enable the use of Gameboy Advanced games.

I didn't know paper Mario wasn't intelligent game. When I think of games that use your brain I think of stuff that you could apply the word puzzle to. Like for example Dr Mario and puzzle League. Thats where i usually see the intelligent systems logo.

Have you tried loading up a Virtual Boy game/rom, considering there were traces on the board for Virtual Boy? Wondering if it would load a game on the dev board.

@landonfitzgerald5044 4 месяца назад

I think that chip you asked about is Nintendo experimenting with 3D graphics since the game boy advanced is technically 3D capable possibly they were trying to push something like that on an earlier console

@gizaha 4 месяца назад

7:30 I don't think there is a firmware on the board, it's just hardware that runs code from the cartridge. The "bios" just checks nintendo logo and locks if failed, nothing more. The glitches might be created from something else, like hardware differences.

try flashing that early firmware to a finished game boy to see if it works

Virtual Boy chip might have been a cost saver? When V B system didn't take off & was discontinued, the may gave had a ton of extra chips leftover...

@reverseretro1961 4 месяца назад

I'm REALLY interested in this early GBC hardware, especially since it has all the test pins broken out, INCLUDING the normally unconnected (NC) pin 39. If you have a multimeter, if you can, I'd probe that pin on the board on the diode setting to see if it's connected internally. If it is, then call me crazy, but this early hardware may be what the GB Boy Colour is based on. I got some hardware test ROMs I'd like to see run on it too!

@danieljimenez1989 4 месяца назад

It would be great to run the tests on both the current bios and then try a retail one. Why dos the presence of pin 39 here point yo this being the origin of the GB Boy Colour and why does this pin do in that unit?

Just wondering if this is consistent among boards of this vintage or if the glitches are present because of some hardware deterioration. Seems rather odd that a test board that was shipped and used for gbc dev couldn't actually play gbc games..

I have an earlier version with a different box design. I also have a rare board where there are two screens and two slots used to test the link cable system. Two carts are inserted and two screens show each game.

Nintendo prototypes are X units... NX is the Starfleet registration for prototype starships. NX is also the Nintendo Switch's project name. NX-01 is the USS Enterprise, pre-Federation. Rambling over.
