So Now that I'm "home" from "work", I can get onto Lemonamiga and Lall of Light. The box cover says you need 1 Meg of ram to play the game. This would be your Graphics memory, not your Other memory.
So if you are seeing less than 1,000K (1 Meg.) memory, you are going to have a tough time running the game. If it says something close to 1, then it should work with disabling the Hard Drives...
Also, if you get to upgrading your system, this game is hard drive installable so that would be a bonus to getting the extra Graphics memory...
