Here are few contributions by me...
Hardware for clockport: The old rrnet revision doesn't physically fit the board, only the new one does. Also unlike retro replay and rrnet, mmc replay with new rrnet fits inside standard module case.
Q: Does it work with PAL C128D (retro replay doesn't work properly)
A: I'll test it at home when I have time :-)
Q: What are the main differences to Retro Replay (and MMC64 / Action Replay VI)?
A: Only new rrnet fits, MMC port, 8 flash banks (instead of 2), memory expansion
Q: How are the filenames sorted?
A: In the order they are copied (no alphabetical sort)
Q: Does it come with case / can I use any standard size module case?
A: There are new cases available, but you need to cut out the holes for MMC card, reset & freeze buttons, led lights and Ethernet connection (if you use rrnet aswell)
