The thing is, there have been a bunch of different Humble Bundle releases, and the Humble Bundle version doesn't auto-update like the Steam version does. First there was the original December 2011 humble bundle version with the Wind Fortress timer and Sanctuary Time Attack glitches. Then there were later releases that fixed those problems. Then there were the releases that added the machine gun challenge, and then there were releases that added leaderboards that didn't work and the action replays that sometimes work. It's unreasonable to assume that the EXE file is unaltered between those versions, and it's unreasonable to assume that every Humble Bundle player is running the latest version of the game. This is a large part of why I've never been very keen on adding features for messing with the CS+ EXE; a patch for one version could easily break another.As far as I know there are only really two key versions:
Cave Story+'s Steam release, and the Humble Bundle release.
