[DolphinWX games won't load]

I keep getting an "Unexpected Parameter" error when trying to launch Mario Kart GP 2 through launchbox. The games runs fine if I open it just with the emulator. Any help would be appreciated.

Some versions of BSnes handles games extremely weird. Version 0.88 is one specifically that is extra funky. I would suggest a different version like BSnes-Plus like this one http://www.emucr.com/2017/05/bsnes-plus-git-20170514.html or something else like Retroarch using the BSnes core for SNES and Nestopia or Fceumm for NES.

I appreciate the link but that version just gave me a black screen. I was finally able to get it to work with FCEUX 2.1.3. Thanks for the response.

I added the bsnes v088 emulator because it runs NES games great in stretched fullscreen. When i try to run any NES game, the emulator opens up but the game doesn't start. I have to manually start the game through bsnes to get the game to open. I verified the rom path and platform so I'm not sure what the problem is. Any help would be appreciated. 

 

Seems to be a problem with entering --fullscreen in the command line. I removed it and the game started in windowed mode. Any idea how to get it to run the game and go to fullscreen automatically?
