Lior Halphon 4e3928df81 Turns out the behavior differs between DMG and CGB – in DMG mode, the objects enabled bit is checked before halting the FIFOs, meaning that disabled sprites do not affect Mode 3’s length on the DMG. 2018-03-23 20:01:27 +03:00
Lior Halphon 48a8db233d Refinement to the last fix 2018-03-23 19:54:11 +03:00
Lior Halphon e9eeace995 The object enabled bit is checked only when popping from the object FIFO. Objects affect timing even when disabled. 2018-03-23 19:50:19 +03:00
