And in my case it's even more of a pain because I have to remove the
GoMMC and the WE 1.44 ROM to fit the Tool ROM before rewriting the
GoMMC, and vice verce.
Oh, BTW, I'm using a patched version of DFS 1770 on the GoMMC (FSNR 2,
from John's website) and WE in ROM.
Any more help here would be much appreciated!
Cheers
Richard
