it's too bad you couldn't get ahold of some of these:

this thing for some odd reason can hold 8 original gameboy games on it

Sounds like you may have missed out by just one pin. I have gotten a full size eprom working before, but I'm just looking into what sort of smaller surface mount parts I can use to make the whole process simpler.

Here's some of my earlier attempts from around 10 years ago:

I also tried to make a gameboy eprom cartrige. I used this schematic (lower left corner of the page):

It did not quite work, I have no idea what went wrong. When I burned an eprom and turned it on, most of the nintendo symbol came up, but there were a few missing pixels and it did not work. I know the eprom was good and the burn was sucessfull.

If you do find a plcc eprom/eeprom/flash chip that is 32k and 44 pins, you can not just replace the masked rom. it is a different pinout, you have to get the cart connector pinout and wire the chip according to it.

I was looking through the only hard copy resource I have available (Nintendo Authorized Servicer Technical Training Workbook), and the only Game Boy schematics I found were for the system and the rechargeable battery pack...

Hi guys, I've recently been investigating puting the original Chunkout onto a GBC cartridge, and was wondering if anyone new much about gameboy rom parts. It would seem to be simplest if I could take a rom only cartridge as a donor for my 32k game, and just replace the mask rom on the board with something I flashed.

The problem is looking at a Tetris board I've got here, the rom looks to be a 44 pin PLCC. The smallest rom I can find that's 44 pin is a 27C1024 (e.g. 1Mb). I'm wondering if these would be similarly pinned, but I can't find any reference material for the rom in the gameboy cart. Anyone have any ideas?
