I am at work and can't try the patch. But just want to say: the idea sounds wonderful. It's fascinating Nintendo didn't store dragon coins with the original game, though the code shows they seriously thought about it at one stage. Would have made the orginal a metroidvania of sorts.
A few suggestions:
1. Could you please make a version without any graphical changes? Love the dragon coin screen idea without artistic changes.
2. I'd like the 100% dragon coin collection goal to result in a message appearing on the title screen, as a simple message, perhaps
no other celebration needed imo.
