Title: Amiga Demos on my A1200
Post by: bradhansen1 on August 26, 2023, 05:54:15 PM

Hi All, I have a Commodore Amiga 1200 Labeled as Channel Z Rev. 1D.1. I have 3 different excelerator boards,
one Amiga-Kit 8mg memory board, one Terrible Fire 1260, one PiStorm 32 lite. None of them will play my
WHDLoad Demos correctly. Does anyone else have this issue and is it just a common one for the A1200?
Something that I can fix?  I am running 3.2.1 Roms and 3.2.1 software.
Any help would of course be appreciated.
Thanks,
Brad Hansen

Hey! Thanks so much for responding. I do not have demos that will run with out
WHDLoad. The ones that I have trouble with are “State of the Art” “Batman Velvue”
and “A1200 aga.” Isn’t there an application where you can turn down the CPU speed?
Really appreciate the feed back.
Thank you,
Brad Hansen

Hi, Download "Stateoftheart" from Aminet and tried to run it.
Just locked up my computer. This is my A1200 with  PiStorm32 lite.

Monitor is attached directly to the Amiga, and not to the Raspberry Pi, right?

Hi, Well I am using a ScanPlus video card. But All that does is let me run Amiga screen modes
on a flat screen monitor.
Thanks,

Erhm .. I don't quite understand. None of your Amigas run WHDLoad demos and none of your Amigas run demos without WHDLoad? Which way is it?

Does the machine just lock up, or do you get an error message?

Try disabling cpu cache in the boot options.

Same thing happens to me, when I use Musashi. Emu68k latest seems to work ok.
