I'd do the same to be safe. I just grabbed the WUD and it extracted properly. You can use it to check against your dump if you want:
91 RPLs:
Size: 112,210,994 bytes
I found that MP10 freezes if you attempt to dump it before getting to the game board screen. Just start the game completely and wait until the dice is rolling, then try to read FSA but again, why bother when it seems unlikely you will be able to successfully dump all 91 RPL's. 91 RPL's is crazy. It doesn't seem likely that anyone could use TCPGecko and Dumpiine to backup MP10. I'm guessing REAL method of dumping our own games is private too or is there other tools for getting good dumps of our own games besides TCPGecko and Dumpiine?...since there is no way of really knowing how many rpl files there are without first having a 1:1 iso/wud dump. Any advice is helpful.
