Nice fix, AWal! Unfortunately it triggers my crude "authorship protection" (for lack a better term) which should make the game crash when entering a battle (odd how no one seems to have noticed yet). If you hadn't overwritten the "Grond1911" right before the vectors it would have worked fine.
If anyone wants to repair the patch themselves before a fixed version is posted, just open it in a hex editor and change 0x3E-46 from "FF FF FF FF FF FF FF FF FF" to "47 72 6F 6E 64 31 39 31 31" or alternatively (if you haven't already applied the patch) delete those nine FFs and change 0x2D from 19 to 10.
Sorry for any inconvenience to anyone who may have already made a cart with this (not to admit fault).
Oh nice, wasn't expecting a response from Grond himself...
I actually just figured out that you had a signature check in place (debug caught reads to the spot)...And I fully understand why one would want to have something of that sort in the file.
As expected, I have uploaded a fixed version of the patch that can be obtained here.
Just to let everyone know, the patch is working well. There is some graphical glitch remaining at the title screen but nothing major. I finished the game and it is 100% playable.
