Latest revision as of 11:48, 1 September 2024

In the following you will find a number of bugs which actually already occur when using the original interpreter / .EXE. That is, those errors are bugs in the games themselves, not in ScummVM.
Still, we are sometimes able to implement workarounds, meaning that ScummVM works better than the original ;).
Also, a list of non-bugs i.e. game features that look buggy and thus have been reported by users, but are actually intentional, is provided for reference.

See also the SCUMM Game Enhancements page for bugs which have been fixed through WORKAROUNDS.

Note that none of these lists is complete.
