I just installed mame64 version 137 on windows 7 PC. I had mame32 Ver.128 I noticed on some games when i open them up its a mini screen. i have the settings the same globally and some open up fine maximized and some open up very small Asteroids, Tempest and Discs of Tron to name a few. anyone else encounter this problem with MAME64 on windows 7. Im thinking of going back to XP. Any thoughts, is there any benefits of have 64 bit oppossed to 32bit in MAME anyway.
