Describe the issue

After talking to Rose during the final cutscenes the game loses audio and has no music during the credits. The audio comes back after the credits roll and the game runs as normal.

**UPDATE- ** Audio issue seems unrelated to OPL as it happens on disc as well. I had to turn off Dolby 5.1 in the options menu (which affects the intro and ending cutscenes), switched to mono audio, then the ending cutscenes' audio and credits music worked.

Settings that worked for me:

SMB OPL Beta 1.2.0 w/ Compatibility Mode 2 - Dolby 5.1 sound OFF in MGS2 Options menu, sound set to Mono. Final cutscenes' audio and credits music working.

Broken/Freezes: SMB OPL Stable 1.1.0 - Freezes shortly after taking to Rose during final cutscene.

Console model

SCPH-75001

OPL version / revision

OPL Beta 1.2.0 2048-17efb44 [Functional] | OPL Stable 1.1.0 [Freezes]
