I guess you didn't manage to launch the game. If you see this message : How many files(0-15)?, it means your game's rom is bad.A USB keybord did the trick
Thanks again
You can check if the game is inserted by opening the emulator's menu (pointing wiimote on screen and press +). Go to "DISK" tab (don't copy kanji1.rom, kanji2.rom for English menu!), if below DRIVE [1;] there's only "< EMPTY >" written, it's a wrong game rom.
You won't need a keyboard if the game is in a good format.
Some games require another Basic Mode too. For instance Punch Ball Mario Bros. only starts on N88 V1S. I should have made it the default one in quasi88.cfg but now it's too late. This option is in the RESET tab.
So, in short, find another game!
