unsupported mapper #6

I've tried most roms for super mario bros and most of them have the unsupported mapper error. Is there a specific rom that is needed?

Hmmm.. yes it is somewhat specific. I believe i used the USA version. The exact string should be in the code base. I am not well-versed in the chaos that is ROM versioning. I know it is a mess but I can't really fix that and I can't package copyrighted ROMs. Its pretty easy to make a mapping for a totally new ROM by the way; it took me just about 8 hours to add Galaga support.

Since the gamepad inputs are the same, you just have to create new mappings for the memory addresses of the inputs; namely the memory address where is 'score' is found and sometimes you may have to tweak the way pixels are processed. Once the inputs and outputs are mapped, the AI will be able to 'brute force' the game (except its more effective than brute forcing, it is directed neural network pattern evolution.)
