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
