Might not have an avatar, but I'm still counting as a Pokemon.
Also, what's wrong with just using a Windows emulator to install and run RCT2 the one time, then just running ORCT2 after.
Or just getting a windows PC because macs suck.
Ctrl+S is the screen shot shortcut, and T disables the interface. Have fun. Also, when things calm down a bit, I will work on the Mine Train, still needs a name.
I'd primarily start with reconstructed Aperture (Portal 2 main design) and maybe add some run-down and old objects after i finish the main set.
If it worked.
