Source Code

there is an archive of .AMOS files and an .Asc file that is updated to compare the difference between each version

the build folder has a 'make' file that compiles FxBox using a custom APCmp command that looks for the AMOS.Library in the local folder, it builds the fxbox custom config and headers and the updated music extension. note: FxBox is fully compatible interpreted with a default installation of AMOS Professional nothing custom needs installing, the customizations are during the build process only.

cd build

execute make
