Strange thing with "one time show" in emu.

Sonic CD regular version passes autosave moment now.

When no save file present, there is no error, bus very slow game because saving file thread doesnt want to stop.
In second run (probably corrupted save file) there i an error MEM: E {PPU[260] Thread (AUTOSAVE)[0x00e0f0a0]} DynamicMemoryBlock::Free(addr=0xc00f30): failed, probably this is what You said. Slow game because saving cannot stop as well.
