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

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.
