*UPDATE* With the Japanese firmware release it looks plausible again but there are still changes that were made that may make it difficult.. *UPDATE* Sorry I just found out this is a dead end they have now encrypted or scrambled it beyond hex editing, none of it makes any sense anymore. Every reference to Create ISO and sakura are gone in 1.33 and 1.34. There is very little hope that we will see an unofficial english version of those imho. -old- Ok after looking at the g6dsload.eng and jp file in a hex editor I know what bytes need to be changed. I also know that the ISO header stays the same between version 1.11 and 1.12. I assume that iso headers must contain the information that locks the firmware to specific cards, but I am uncertain if it contains any MFT information, I think it would be larger if it did contain a MFT so I think that is unlikely. Please take a look at address 0000 5BB0 or "Create ISO" and you will find that the following bytes start to change and it also shifts the data some.
