Metroid Zero Mission: freezes at the endgame cutscene

[mrachinskiy]

Game freezes in certain point of endgame cutscene (when ship starts to blow up). But issue is not presented in older releases.

Broken: d22315c dev build and 0.6.1 release.
Works: 0.5.2 release.

Save state for 0.6.1 and later
Save state for 0.5.2

Reproduce issue:

1. Use 0.6.1 release or devbuild (d22315c)
2. Load save state
3. Unpause the game
4. Board escape pod to the right
5. Wait for cutscene to freeze

Is this broken in 0.6.0 too?

E] Confirmed broken in 0.6.0 too.

Regressed during the mTiming cutover (after e423cd4 but before 9aa6d8f). Seems to be related to either timers or DMAs.

I'm not 100% sure this fix actually fixes it, but in my testing it seemed to. Let me know if it doesn't and I'll reopen the bug.

Tested fc53fc9, no freezes in the cutscene. Thank you!

My fix for this broke a bunch of other stuff unfortunately.
