Editing Existing Patch

[alexkost]

I want to dip my toe into the world of FFT hacking. I've been reading various threads on here and reddit to try and learn the basics.
If I understand correctly, FFTPatcher can be used to both create new patches and to modify existing ones. I wanted to start out by making some small changes to FFT: Emergence, but every time I try to open the patched iso under the PSP menu, I get the following error:
"an error of type FTTPatcher.Datatypes.FTTPatch+LoadPatchException occured:
Could not load patch"
Am I missing something small, or just going about this all the wrong way?

Thank you,
~Alex

I never had that error but you may be doing something wrong, like opening a PSX ISO.
Keep in mind you have to patch an EUR ISO for the Emergence patch and then you can edit it.
Maybe it is not opening because you may have patched an US ISO, it shouldn't be failing. Try to use the lastest version of the program too.
