Mapper 7 support #28

Open kraln opened 7 years ago

kraln commented 7 years ago

This should add support for one-screen mirroring as well as mapper 7 support (AxROM). However, something is quite wrong--the mapper is pretty simple so I think this exposes some other weaknesses (particularly with the PPU). Not sure though, I've been wrong before.

Partially addresses #8

What do you mean "quite wrong"? Do you have some screenshots?

Here's some pictures. Note that MMC3 has some issues as well. Not quite sure what's up with Mapper 7 http://imgur.com/a/0gX6G
