There should be a way to manually fix the tv-out, but I need to do some tests and I don't think it'll be in 0.6.
BTW I was wandering through squidgesnes code and I found out that it supports command line. It was mentioned in the readme but it didn't work.
Reading the sourcecode I found that the parameter to launch a rom is "load=/path/to/rom" and not "loadrom=/path/to/rom".
That readme needs to be fixed.
