Hi, I use always QT version, I asked Metal Gear Solid mods and they said QT is totally okay. My TEKKEN saves are on QT, I tried to export them to a new memcard to be played on NoGUI, but doesn't work... Is QT okay for TEKKEN too? Or relly only NoGUI? I hate NoGUI not gonna lie.

Is there really a difference between them?

QT is fine, NoGUI is no longer supported by DuckStation.

As long as you can get the special menu up which is requested (there's a hotkey where you can do this it's assigned to Escape on default) then you're generally fine.

Waaah thank you so much Spikestuff!! Now I'm ready! And I just found the hot key, makes things so simple to navigate!

Thanks for the quick answer, I did'n expect it would take that fast to get a response ^w^
