If you try to run the original CD-ROM of Rollercoaster Tycoon on Windows 10 or 11, you will encounter a graveyard of issues: black screens, mouse lag, "Unable to initialize graphics," and color palette corruption that turns your park map into a neon rave.
"Game crashes when building a coaster." Fix: This is almost always a RAM limitation. On Windows XP, RCT cannot handle more than 512MB of system RAM allocated to it if using the original .exe . Use the /3GB switch in your boot.ini if you have more RAM, or simply run the game in Windows 98 Compatibility Mode even on XP . rollercoaster tycoon windows xp
