If you plan to use an emulator to speedrun this game then I would recommend using citra, I've been informed by another moderator that an I'm allowed to link it but you must go by your own terms acquiring the game. Citra is the most worked on and stable 3ds emu at this point and I can personally confirm that Tekken 3D: Prime Edition works alright on the emulator if your specs are good enough to run it (Compare my video to SlawPro's for an example). The emu is constantly being updated so hopefully the game will be more stable for lower specs.

For those that use OBS and this game (if anyone even does) does anyone else having a problem with getting this game display using window / game capture.
For me its a huge issue im having to use display capture seens i cant make the game windowed
If anyone can find another work around i'd like to know :)
You can either use Emulator, Direct Capture or handheld camera capture as long as the gameplay and times are visible and clear it doesn't matter.
Is using an emulator allowed if so what ones i'd be interested in starting some runs for this
Anyway to disable autosave on the PC version, Looked around for a while and can't find anything on it only stuff about problems with saving.
