I am new to this forum. In fact I just googled "atari forum" and got this as a first result so here I am
I have basic programming and electronics knowledge and have an idea to use a cheap microcontroller to replace the eprom of an atari 2600 catridge.
A few years ago I played a bit with the Batari Basic and ever since I have always wanted to have a homebrew game playing on a real system.
I plan to use an attiny85 or an atmel328p (the one in the Arduino Uno) microcontroller, some shift registers for expanding the input and output and perhaps an external storage (an SD card or a cheap memory chip). The microcontroller will read the address lines and will output the corresponding data from it's memory to the data lines. I think today it's much easier to program and interface with microcontroller than an EPROM or EEPROM chip.
Please share your opinion why this won't work or what I can do to improve it.
Also is this forum the right one for such topic?
