Super Robot Taisen OG Saga - Masou Kishin F - Coffin of the End [BLJS10284]

RPCS3 v0.0.4-6270-a6208d2b Alpha | HEAD
Ingame (maybe even playable).

Performance looks decent especially for an AMD A8 integrated graphics and the PSN version is playable and has been for a long time. I'm going to move this to playable.

There is an issue when you do a final attack the game slows down really bad or just straight up crashes i don't know how to fix this. This is not 100% playable.
E SYS: 'sys_mutex_unlock' failed with 0x80010005 : CELL_ESRCH [1]
E SYS: 'sys_mutex_lock' failed with 0x80010005 : CELL_ESRCH [1]
F VM: Access violation reading location 0x1c (unmapped memory) [type=u32]

Using any character's ultimate attack causes the game to freeze,

The error message in RPCS3 log is :
F VM: Access violation reading location 0x1c (unmapped memory) [type=u32]

This problem had been reported years before, both in English and Japanese sites, yet still no fixes or effective workarounds available.

This game is not suitable for "Playable" rating.

There is a fatal bug that causes freeze when you use ultimate weapons.

I've been waiting years to run this game on RPCS3, but all I can tell you is that it's never appropriate to get "Playable" rating.
