Well, either that or the deton levels out far enough behind eggman that his speedup doesn't occur and they both just scoot forward really slowly. Otherwise overflow to negative numbers, yeah.Well, presumably the game would either overflow error or you'd max out at 2^16-1 or whatever the cap is. For those that don't know, Detons have a variable speed based on the max speed of whatever they're chasing. This would lead to a clear feedback loop if Eggman on foot was playable =P
