Jojo's Biz. Adv. rgb/scart fix

[GL]

The problem is I don't have the original image (.bin/.cue), but instead found a .cdi image somewhere. Most of you will probably know that the specific patches are restricted to the original images.
Anyone got a clue on how to apply the fix in another way?
I was thinking of using hexedit, maybe the necessary hex info is in the patch. But I can't open the .ppf format.
Maybe only the 1st_read.bin has to be adjusted?

Any help would be greatly aprreciated TIA

Unless you know the position of 1st_read.bin in the original image, hexediting won't help. This is (more or less) how ppf files works :
_ position | length | bytes to change
_ position | length | bytes to change
_ position | length | bytes to change
...

You can't know the original value, so you can't look for them in your image. Position is the position in the original image, so if your image isn't build the same way as original, it won't help more...
