I thought I should let you know that I plugged in the 2Mb SRAM card with the Amiga A1200 turned off as advised, turned on the A1200 and found that my card was immediately recognised as 2Mb of "other mem".
One by one, I clicked all the little square WHDload icons and nearly all of the games I'd installed worked! These included Beneath a Steel Sky, Lure of The Temptress, Elvira Mistress of The Dark, Eye of The Beholder, and K240.
As previously under WinUAE with 4Mb, games which required the Kickstart image kick40068.a1200 wouldn't work. These were Der Clou, Der Clou AGA Profi Disk, and Eye of The Beholder II. I copied this image off my Amiga Forever DVD and have even tried copying and renaming it with the extension .A1200 as well as .a1200 with the .RTB file named accordingly, but this had no effect. Perhaps the image file got corrupted when I copied it off my DVD. I'll try to reinstall it.
Games which had some problems with RAM were AlienBreed3DAGAFixed "Can't allocate ShadowMem", and Dungeon Master 2 "Can't allocate ExpMem".
Unfortunately, while testing a lot of these games, I noticed that the screen often went black for about one second or less in the middle of the games. I suppose this is due to either the new 2Mb RAM not being ChipMem/Graphics Mem or it being 16 bit instead of 32 bit.
I'll try to tear myself away from WHDload now to get ready for a night out, but I could do some more with it while I'm getting preloaded (i.e. with alcohol), which is much easier than preloading with WHDload. :laughing:
