Nilex, Avenger and anyone else,
Thinking of this game again made me realize that I could adapt my Outlaws Mouse Helper to this game, so I worked on that tonight and it seems to work well. If you're interested in testing it, I've attached it. Copy it to where your dosbox.exe is and run it, then run SkyNET (unless it finds it and runs it for you, which'll it'll try to do).
There are only two features (since the game is quite a bit simpler than Outlaws... no reload, no inventory, etc.):
* Cycle weapon types (#s 1-7 on the keyboard) by scrolling the mouse wheel up/down.
* Cycle weapons of the same type (i.e. weapons that share the same # key) with the middle mouse button or scrolling left/right.
To really test it, you might care to use the game's cheat code to give yourself all weapons: press Alt + \ then type in Arnold and hit Enter.
If you try it, let me know if it works well, has issues or if you can think of features to add or other ways to improve it.
