Ok, ive managed to solve this by turning off the transitions in Simpletouch. Not sure if it was because i had it on random trans and it didn't like it or because im only running 512mb of ram but they are off and sorted. A nice to have as are swf but rather it run stable.
Im still confused on what is the best way to run the credit exe's.
As said i run itbox emu and sim on specific game launches as required but INDE platform I have running on startup and have to add credits manually, this seems to be needed for certain games.
Can I auto add credits and it seems to disconnect too.Any best setup ideas?
