Open Mugen PSP Question I NEED YOUR HELP!!!!!

ALright so I just found this homebrew app yesterday. I am using a PSP Slim with 3.90 M-33 CFW. I extracted all the files like you do with any homebrew game. When I was done I went onto my psp excited to play my new homebrew game. I went to my saved data or where ever your homebrew games go and there it was. It wasnt corrupted. I clicked on the App super super excited.It loaded just like any psp game but then I got " Game could not be started "
What am I doing wrong? Here are things I think might have caused it

1) I added characters just like you would with PC version of Mugen. Do i need the PSP character converter?
2) There was no folder called select where you could put maps and characters.

What am I doing wrong I need your Help!!!

Its likely a 1.50 Kernel app.

Slim doesn't have 1.50 Kernel.

Could you post a link, just to be sure?

I saw online that it didn't matter the CFW

That is app is indeed made for the 1.50 kernal. Like roxfox said slim doesn't have a 1.50 kernal addon. I'm not sure if you can run it in Time Machine though.

Yeah! Try to TM to 1.50. Upgrade to 3.52 and then whatever you want.
