Grand Theft Auto: Liberty City Stories

[FrozenDevilz]

Does anyone can help to figure out how to make it stop slow-mo & lagging?

I have these configurations, maybe some of them wrong

And I do know we do not have the same PC

I just need some suggestions / recommendations on the configurations

So it can run it better on my emulator

Thanks before~
