Before Xmas I brought out of retirement an old Amiga 500+ from the attic. It had been up there for a number of years and had succumbed to usual NiCad leak, cleaning up and a repair to the FDD got it up and running and my 4yr old grandson absolutely loves it. Unfortunately time has taken it's toll on the floppies and a high proportion no longer work so a Gotek emulator was purchased. This has given the machine a new lease of life but I have problems with a couple of games which to me look like some form of memory issue.
Two titles affected are Arabian Knight (my personal favourite) and Fire & Ice which have graphics issues. From the pics below can anyone confirm if this is indeed memory related or possibly some issue with Fat Agnus? I must add that the original floppy based version which were still working and showed the same problem so it doesn't appear to be associated with the Gotek. We have two Amigas and still have the original A500 to look at but I don't think the above titles ever worked correctly on the A500+.
Can anyone suggest any memory tests?
