This repository contains GTA specific code. The library librwgta proper has Rockstar specific plugins for librw.
Under tools/convdff and tools/convtxd there is code for some dff and txd conversion utilities.
tools/storiesconv converts a number of file formats of GTA Liberty and Vice city stories to standard RW files.
Under tools/IIItest you can find an ongoing project to reverse engineer GTA III.
Currently it can render the map:
tools/storiesview is a map viewer for PS2 LCS and VCS.
tools/euryopa is a map viewer for GTA III-SA that will become an editor eventually hopefully. Since it depends on LZO, which is GPL, consider my code in this repo dual-licenced as GPL.
Set the LIBRW environment variable to point to the librw directory. Otherwise just like librw, i.e. premake5.
