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 066efab985 In DMG mode, the length registers are not affected by turning the APU on and off. Why? Why not! 2017-08-11 22:23:03 +03:00
Lior Halphon 0e22ad8eb1 Noise channel support 2017-08-11 17:57:08 +03:00

Lior Halphon baccf336d7 Complete rewrite of the APU. Channel 3 is complete and passes all the relevant tests from blargg’s suite, as well as PCM34-based tests. Actual sound output is basic and limited, though. 2017-07-21 19:06:55 +03:00
