MisterMsk created 2 ROMs for the MMC Replay/Retro Replay. This is the sd2brwse light file browser for the uIEC and the SD2IEC drives by Hannu Nuotio. It was version 0.6 that was modified.
MisterMsk (with the help of people from Lemon64 and retrohackers.com) has added a 3 second delay to the program and changed the colors a little. He also changed it so it defaults to lower case. Finally, it defaults to the SD2IEC/uIEC being drive 8 (since most games use this by default.).
There have been two updates lately. Also, 32k and 64k images have been made into CRT files for emulators.
