On the games that refuses to run because of lack of enough FAST RAM, simply edit the icon "properties" (in Amiga we call it "information") and put a semicolon before the "PRELOAD" option.
Expect to see a "slide show" while the games load, but they will work.
Don't know how? Easy:
- left-click once in the game icon;
- hold the right Amiga key (on the right of the space bar) & then press the "i" key;
- On the opened window, click on the PRELOAD option;
- On the under space put a semicolon before the PRELOAD word;
- Press on the return (enter) key;
- Press on "save" button;
-Test the game again.
If you don't like the screen blinking, buy a 4Mb SRAM card, but they are expensive as hell.
You'll find them very often in Ebay auctions and even on Amibay (cheaper and only "Buy-it-now"), but they are rare. Also I found those in various other sites around the internet.
