Advanced users • [Help/Advice needed] Pi Zero W as a virtual ROM

Hello fellow tinkerers!

I am working on a project, that consists in transforming my RPi Zero W into a GBA cartidge (Kind of).

My idea is the following:
- Maybe a web server to upload them (easy part)
- Connect the GPIO pins to a board as if they were the ROM pins
- Emulate ROM behaviour from the GPIO pins

The hard part (for me) is the two last points.

What I have done so far:
- Ask ChatGPT
- See that the answers are misleading (Eg: Told me at first that the GBA was working on 5v)
- Wire the "Address" and "Data" lines to GPIO pins
- Then ask myself if I should continue asking GPT
- Decide to not
Oh and I have a program that ChatGPT gave me, but I'm afraid that it may not make sense (or yes), but I can't tell right now (Pretty new with using GPIO).

So if you know good resources to wrap my head around how ROMs work, and familiarizing me with Raspberry's GPIO pins, I would be very grateful.

Thanks!

PD: I have experience with basic things like making simple programs for Arduinos and ESPxxxx modules, if that helps.
