I thought I’d take a little break and tear something apart, this time it’s the Super Gameboy SNES Adapter which allows you to play Gameboy games on the SNES.
Lets flip it over to see some chips.
So what do we have here, it seems some of the chips look a bit similar to something else… the actual Gameboy!
I don’t have a Gameboy Colour to compare to I do have a regular Gameboy and you can spot the similarities: both have the same sort of CPU, both have identical 2 x 64K SRAM and another chip.
The CPU of this unit which I assume would be working like the CPU in the colour gameboy does. You can see the traces of the CPU go directly to the Gameboy cartridge header.
2. 64K SRAM x2
The 2 memory chips for the CPU to do it’s work with.
3. SNES Lockout Chip
According to this website this chip seems to be used as a region lockout.
4. Some kind of ROM chip
As you can see by the traces on the PCB this chip communicates with the SNES side. According to this website might be a ROM chip?
Seems to also communicate with the SNES side too and with some lines going to the CPU. It kind of looks like a MBC chip but I probably am wrong.
So that was just a quick tear down, I thought that there would have only been 1 chip to handle reading the ROM/RAM and somehow this chip would emulate the Gameboy but I guess back then it might not have been possible, so they just stuck the guts of the Gameboy in it instead.
