Gta LCS crashes on android #11381

Closed marcospampi closed 6 years ago

I recently got my heart broken by a crash while playing this game, the mission is the one you inspect the yakuza's ammo repository, immediately after the first cutscene on stanton. Tried both vulkan and opengl.

If you save in game, and then load your save, does this still happen?

If so, can you try going to Tools -> Developer Options under Settings, and changing the CPU Core to IR Interpreter? It will be slower, but if it still crashes, the backtrace will be more helpful. If it doesn't crash, that will be useful information too.

Another thing to try (this won't lead to a better backtrace or fixing the real bug) is disabling "Fast Memory" under System. This will make it emulate slower and consume more battery, but rather than crashing on bad memory access (like the above), it will try to ignore it and keep playing the game.

That might workaround the issue, but a real PSP would crash on bad memory access. So ideally we want to fix the issue.

Also: make sure you're trying with the latest git build.

Could have been some memory overflow issue? I did saved the state just before the cutscene begin, If I go straight to the cutscene the game would crash, though I've ride around and then it didn't crashed. So looks like that the issue can be closed, I hope the error log could be handly , sorry I didn't backup-ed the state.
