I've just downgraded back to 5.3.2 from 5.3.3 on mac osx due to errors and crashes.
Program quits when trying to auto rename a ROM and also an error is displayed when viewing ROM info.
Didn't get as far as trying to put ROMs onto the flash card.
I went to a garage sell last saturday, and the lady had a PS2 for sale, but she had a sign on it that said "Nintendo -$50", had to laugh, almost bought but she didn't know if worked, and she didn't have controller or cables, so I passed.
