Can I use an emulator on my pc and still submit my runs? This will be the first time I get into speed running so I'm a pretty big noob. I was wondering if it's ok if I use an emulator..

Yes?

Don't use bizhawk or SNES9X 1.43.

where i find the rom for this game? need a german version

you would want to play the NTSC version. it's either english or japanese.
