I got my Pi version 1B (256MB) many years ago and have not used for anything in a long time, so now I found time to test Amibian 1.4.1001 on it.
First thing I found was that if I tried to use the uaechipsp1 the GUI starts, but it will quit back to the terminal if I try to start the emulation. So I set Amiberry to be the default emulator.
Setting up the emulation system was easy enaugh using the midnigt commander. I had a few WinUAE setups already, a basic OS3.1 install and a customed WB39.hdf which was a recreation of my old A4000 setup.
The basic WB3.1.hdf did work to boot from, but I had trouble booting from the WB39.hdf. What I did then was to create a new hardfile in amiberry, then tranfer it over to WinUAE and copy across all files. Now I could read the WB39.hdf on amiberry, but not boot from it. Then I managed to boot from wb39.hdf as hd1 if I had the WB3.1.hdf as dh0, set as not bootable. After I had this running, it suddenly booted happily from the wb3.9.hdf drive without any other drives present.
Now adding some WHDLoad games to test, only to find it was dreadfully slow. JIT does not seem to work for this emulator on the pi1, everytime I have tried to tick on JIT it never boots up. Perhaps this is due to that my pi only have 256MB ram. I tried various setups to improve the speed, but it looks like the speed is the same if I launch a game just using a A500 floppy disk setup with a Harddrive and WhdLoad.
To get it into a near usable state I set the overclocking to high, which seem to run stable.
I used a couple of plattform games to test, JamesPond and Superfrog. They are playable, but comparing to a WinUAE setup I have I can see that they are slower. I found they perform best using the setting Fastest, or just 7 mhz.
WhichAmiga reports highest Mhz if I set the cpu to 25 Mhz. Setting it to Fastest, it says I have 4,7Mhz. Turbo makes it report 1,8Mhz.
Looking at the game performance, I'd say that 4,7Mhz feels most accurate.
To sum it all up... I have just ordered a Pi 4B
