Hey guys
Glad to see so many people trying hard to get this classic game working
Naturally I've also been having hassles, I will be trying some of the ideas listed above, but one odd thing I found was that for me to get the game to run at all, I have to open a command window and navigate to the .exe DOS-style, I dont know why but if I just use a shortcut I get kicked back to desktop...
still having plenty of other problems, the worst being that when I hold the cursor over an enemy I get a little 'Gun Shoot' debugging pop-up telling me the co-ordinates, which also causes the game world to respond incorrectly, allowing me to walk through walls and stuff, I've found that I have to reset the computer before each level, this seems to be the only way to get any kind of playability, still sometimes get odd things (pictures of checkered flags and light-bulbs) on the top level, but that level is hardly ever actually used in the game so no biggie there...
The moral of the story is: it IS possible to run it on XP, but you have to be pretty dedicated, and I'm glad there are others like me out there (and keep posting any fixes\partial fixes!)
