Probably if you are well versed in BlitzMax, C++, OpenGL and MOS's APIs, then it would be easy. But I know nothing about any of them :( Let's hope your coder friend works quickly through his to-do list :-)

Ok, here's something interesting. The only part of GridWars which seems to use GL is the rendering of the grid. Since this is not essential to gameplay, I went through and commented out every line of code relating to GL. The result: the game compiles and runs fine (minus the grid) on my MacBook. I'm just installing XCode under MacOS on my PegII. Once it's finished I'll try to compile the modified GridWars and see if it runs. If I can get it running, I'll try to learn enough BlitzMax to replace the GL lines with native Blitz commands to allow the grid to render in software.

Wish me luck :-)

Hmmm it didn't work. I got loads of errors from the 2D functions when I tried to compile it on MOL :-( BlitzMax code looks very readable, so if I can learn enough C++ I might have a go at porting it to MOS.
