Less than ten years have passed since the release of IMG Pro 1.2, I wrote a new version of IMG Pro 1.4.
It is completely rewritten using OOP, STL and common sense.
The sources can be viewed on Github.
The program has fixed a bug with adding new (those that did not exist before) files to the archive, added a function for rebuilding the archive and other useful options.
Fixed: in version 1.2, when adding several new files (with
increasing the number of files in the archive), the first one (at offset)
the file is in the archive, and the game could crash.
If in GTA:SA using IMG Pro 1.2 you add more than three new files to gta3.img (those that were not previously in the archive, that is, the number of files in the archive will be increased), then the first (at offset) file bbb_lr_slv1.dff will be damaged and perhaps the game will crash sometimes. This bug is fixed in version IMG Pro 1.4.
