Hi, do I need to have an NTSC-J console to play Super Mario 64 Jap? Or Modding my PAL N64 to play NTSC games is alloud for Speedruns?

Hi, excuse me I have a question, I'm about to buy a Sega Master System-II PAL and the seller tell me that he can do a Switchless modd, is it allowed for Speedrun?

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?
