You tried WHDLoad games which needs fastmem.
You could try to set in the icon properties(tooltypes) with this symbols () around Preload and you can have more games to start.
But you see when loading Games black flashes.
The best way to play WHDLoad games you need buy a memory expansion or an accelerator card. For most games is 4 MB of Fast RAM enough.
Remember when buying a memory expansion with more memory than 4 MB, you can't use the PCMCIA port. There are a few accelerator cards which also has this issue.
The best accelerator cards Blizzard, ACA GVP and Microbotics.
