Two of my SNES games (Asterix & Obelix + Brawl Brothers) are documented as 10Mbit games. Unfortunately, the Retrode doesn't seem to support this (latest firmware). It auto-detects as 16Mbit (2MB) and if I try to force 10 Mbit it detects 40Mbit (5MB).
There is no such thing as 10Mbit games as per the SNES header. What's wrong with the 16Mbit dumps (except that the emulator may complain about checksum)?
