i don't know...it still has issues with the entire last level crashing the game too (the clone vats), though I think thats the steam protection not the trainer itself. I don't know which bosses they tested the fix with, I'm pretty sure its fixed with the gorog...the tram thing may not count as a boss (most guides list the gorog as the first boss of the game)
health option is not the issue...force fury did however crash my game twice...so i never turned it back on...i never had a problem with rest of the options plus the game's buggy. leave force fury off guys and gals.
