Hi there,
my friend and I are currently on a project for school. I don't want to get too much into details, but it's about a GPS and air pressure sensor module which sends the data to the gameboy.
Currently we have a simple circuit board, just an EPROM connected to the pins on the Gameboy (can be viewed on attachement).
We already coded some programs (simple games, color text, etc) with the Gameboy Code Editor and the GBDK and transferred it to the EPROM - worked like a charm.
Now comes the tricky part:
For our project, we need to access to the Address Bus (A0 - A15) via the program on the EPROM. That means, we have to be able to set a certain Address line (e.g. A1) to either 1 or 0.
We have been looking for hours, but still couldn't find some commands or hints. We would be very grateful if anyone could provide us some information
Many thanks in advance
