OK folks, new release out.
SNES9x PS3 Build 4.3.7
A lot of changes. First off, much smaller pkg files. Second, no more separate '480p' and '720p' version - they're rolled into one.
That's just for starters.
Also, a word of warning on the resolution changing:
** - NOTE: You may get a black screen if your screen does not support 720p or you're not on a HDTV/monitor - in that case, try pressing Left again so you revert back to 480p
In any case, this should be a non-issue on most modern TVs/monitors, or just for those that do have problems, we're going to look at some ways of first determining whether the PS3's output device (the monitor/TV) actually supports said resolution before toggling it.
BTW - to the guy with the Earthbound controller problem, try this -
Go to the Settings menu, set 'Display button input' to ON, return to the ROM menu by pressing Circle button, then click L2+R2 to go back to the game, then tell me if you can see button characters on the screen when you press a button. This might help us determine whether this can all be chalked up to input lag of your telly, or whether it's a faulty controller.
