Okay i got you before about the literal patch you meant, but that’s what i tried to explain about it. With OpenBOR games you can’t do that like you described with xdelta or whatever. To me something like that would be cool actually and i wouldn’t mind it but that’s not possible as far as i know. But just in case there’s some compatible software out there that can do that, i have no idea of how. That’s up to you to try and find it out, i have no problem with that.
