0.7.1 released.
I tried sims urbz with %130 overclock. It's worked. %150 and more probably gives more fps and smooth gameplay but it's enough for long term play.
I tried on few devices.
Android(samsung galaxy Tab FE) - works good.
Switch - works good(But secret garden scenes not works sometimes)
Win11(10 gb ram with rtx 3050) - works smoothly.
Yeah, when only active the fastforward. I think it's a bug. Try to delete old file and replace the new one. Try to 7.2, 7,1 or 7.0.
These versions works all pkmn games with zero problem on save files.
