Visual glitches in GBC mode

Open joeldipops opened this issue 6 years ago • 2 comments

Watching the intro to Zelda Oracle of Seasons, there are numerous visual glitches such as the wrong tile or colour palette being displayed. Suspect this is due to unimplemented gbc features, such as VRAM banking.

One issue that was affecting all cartridge types but I think was part of what I was seeing here was the LYC interrupt not being implemented correctly. Fixed the bug there, but there are still others.

The Window using the wrong tileset thing in GBC could be the interrupt not firing on the correct line due to "double speed mode" not being implemented correctly.
