* Add new error message for detecting if run on DSi/3DS consoles as this program isn't really compatible with those consoles for obvious reasons. * Add initial support for SuperCard Lite (and possibly other SuperCard varients). Note that saves are not currently functional though. * Add back initial support for EZ Flash 3 in 1 Plus. Note that NorFlash commands appear to not be working at the moment. RAM mode untested. New code added for detecting 3 in 1 Plus when detecting max allowed file size. This should allow writing 64MB gba roms to 3 in 1 Plus...once NorFlash stuff is fixed that is. :P * Tested as working properly with regular EZ Flash 3 in 1 carts. * Note that version 0.58 already exists but we do not have source code for it. (source was released only for 0.57. Rudolph could not find the last version's source code unfortunately. This is why 3 in 1 Plus support is incomplete. (it at least detects it now which original 0.57 could not do and will in theory allow writing 64MB GBA roms once NorFlash stuff is fixed for that cart)
