So I'm planning to play a certain hack of FireRed (namely Ultra Violet) and from what I've heard v1.1 has some bugs fixed compared to v1.0. Thing is, RomHacking.net doesn't tell me whether I should patch it to v1.0 or v1.1, they only specified that it should be the US version. Now, are the differences in v1.1 actually substantial enough that it would make hacks made for v1.0 incompatible or not? If yes, which version is more commonly used for hacks?
