What a day ... the 3 emulators I currently have configured on my CAB PC (mame, vice and z26 (atari 2600)) I have just managed to get all compiling successfully (the produced exe's even run !)
Now I can start tinkering ....
I have to say, it only took me about 2 nights to get all 3 done. I was surprised at how easy it all was, well done to the authors !
The hardest bit was finding a copy of masm (to compile z26) on the net, and even that was fairly trivial.
After such a satisfying day, just thought I would send this post.
