This is a patch that I made back in 2002. It is meant to solve the following problems when trying to play SQ4 on recent MacOS versions.
– The game was forced to run in 24 bit addressing mode, like oldest system did. It no longer crashes when started up.
– Time was not correctly handled by the KGetTime function which made a wrong use of the OS Time variable.
To use this program, simply drag it into your Space Quest IV game folder and run it.
