Hello Mr Mugo :-)
It worked with almost every single game before you purchased it from me. I believe you may have to upgrqade your WHDLoad to the latest version (16.2?)
Also run SnoopDOS for the ones that freeze before the WHDLad splash window opens.
I never had to change anything in the WHDload games Tooltypes Icons except adding NTSC....since I play my Games in NTSC mode if possible.
But Run SnoopDOS.its excellent and might help you locate the problem.if you dont have it...get it on Aminet I think.
If that doesnt work...try another type of 32MB SIMM
Also of course make sure you have everything that is required by the WHDLoad package in your C: directory..........VERY IMPORTANT!
