Another old GTA 1 map editor. It has almost the same functions as Junction25. May be useful because... it has its advantages.
M1 v0.95b. M1 was the first GTA map editor, but was originally created for DOS. Following the release of Junction25, Sam created a new Windows-based version of M1 in 1998 and added a full 3D map view to the program. Sam later teamed up with the guys from J25 and created a beta version of J25-2.0, also available on our website.
System requirements: M1win works best on windows98. It’s not a fact that this relic will run on modern Windows, but nevertheless, you can try, maybe it will work. I can't guarantee that it will work properly.
