I actually considered this as well, as the first time it happened I had recently closed the home menu. However the last couple times it happened, I was not using the home menu =(
None of what others have suggested have been what happened to me during the freeze (Trophy acquisition for example). I uninstalled and reinstalled the game data, hoping this will fix it. I dunno. I don’t mean to sound so overly dramatic about this, but every other game in the world can have bugs and glitches in it and it won’t phase me a bit. But when it comes to my beloved fighting games, I’ll switch consoles on the drop of a hat if I have to.
The only thing that gets me is that, like stated in my original post, this all happened to me during SFIV’s launch…how come then I never heard anything about SFIV PS3 version and complaints? I know I wasn’t the only one that experienced it as I’ve had others share their similar stories. I admit I want to play the extra characters for fun on the PS3 version, but it can’t compete for a 100% bug free match if that is my only option.
