Lior Halphon a1a13c61bf On CGB, the VBlank and STAT interrupts are “delayed” by one T-cycle (relative to IF) since they’re not aligned to a T-Cycle 2017-09-03 00:41:52 +03:00
Lior Halphon 0532d2a159 A test ROM I wrote seems to contradicts some of AntonioND’s findings regrading PPU timing in CGB mode. CGB mode now behaves like DMG mode until I figure out what caused the difference. 2017-09-02 23:51:02 +03:00

Lior Halphon 86332d0311 Modifying WX and WY outside of VBlank is now more accurate, but still requires more research. Closes #6. 2017-05-12 19:33:42 +03:00
Lior Halphon c766704267 More accurate FPS capping that tracks time correctly even when the screen is off. Should also support restarting the LCD during blank to increase FPS to 63. 2017-04-21 16:00:53 +03:00

Lior Halphon a925ef130d Stabilizing API: New joypad, debugger and reset APIs; internal APIs and direct struct access are no longer available without defining GB_INTERNAL. The SDL port uses the new “public” APIs, as well as most of the non-debug Cocoa code. 2017-04-17 20:16:17 +03:00
