I ran Generations with the Hedge Mod Manager utility https://gamebanana.com/tools/6311 and its the "System - Allow Controller Hotplugging" code this time; didn't have any controller de-sync issues, so, maybe good?
I wish the game didn't give you your instructions for a Challenge by overlaying your personal space with a orbiting flying creature and huge subtitles, and throwing a high-pitched explanation at your ears, just as you're starting a race and trying to accelerate to maximum speed and see upcoming obstacles. : PPP
It also loves to make it easy to jet-boost Sonic to his own demise; heck, in the second boss battle, it makes it look like that's the way you're supposed to go. Aggravating.
Those doppelgänger races are giving me anxiety, I think the sore shoulder was coming from crushing down on the d-pad too hard while running stages like those. Gotta chill! BP
