you have to create a txt file in the roms folder. use this as your rom file. so SEGA RALLY 3 would be SegaRally3.txt
follow the --profile= when you set teknoparrot as your emulator and add the system it defaults etc, once imported edit the game, click emulation tab down the bottom, tick use custom commandline parameters, and then add --profile=xxx.xml file ( for sega rally 3 it is SR3.xml ) (find this under userprofiles in teknoparrot emulator folder) for each game.
