ScummVM
This page contains a custom ScummVM build along with the source code. The custom build will skip the copy protection on Indy3 and Monkey1 EGA in addition to the usual behaviour. The source files were downloaded from the GitHub repository, the only source file modified is "\engines\scumm\script_v5.cpp". The Windows binary was built using MinGW and compressed with UPX. The binary is a drop-in replacement, to use it simply extract the binary and place it in your ScummVM installation folder overwriting the original "scummvm.exe" file.
