Submission Details

Name: Fix Turning On NMI
Author: spooonsss
Submitted: by spooonsss
Tool: Asar
Requires Free Space: Yes
Bug Fix: Yes
Featured: No
Description: Fixes how NMI is turned on, which can make HDMAs malfunction for a frame after e.g. level loading.

When NMI is re-enabled during vblank, NMI fires immediately. If this happens on a late scanline, we may run org $0082B9: STA $420C after the next frame has already started.
