Super Mario Bros. is NROM (mapper 0). QND doesn't convert mapper 0, 1, 2, and 3 games properly sometimes. To get mapper 0 or 3 games to work (if they don't work), open up the converted PCJr ROM in a hex editor and change byte location $13 (HEX) to "00". If that doesn't work, then post to the board again.

Super C is an MMC3 (mapper 4) game. It should work just fine on the PCJr, so I don't know what to suggest for that. Try to find a good dump of the ROM, or get the Japanese ROM and try that in the PCJr.
