Is there any way to change the NES palette? I have GM running on an NTSC tv, the resolution and refresh are perfect but the colors look nothing like my real NES. I don't know how mame generates its NES/Famicom palette but I assume I can't just load a different file like most other emulators.
Also, arcade roms like Super Game III that have NES games in them also display the colors incorrectly.
