Re: Running 26 bit software on Raspberry Pi 3 B

You need to read the "Pi requirements" section on the ADFFS 2.64 download page, which detail what you need to do for legacy modes to work on a Pi.

the Star Gate is indicated by a triangle of white dots - the right way up if you're flying towards it, or upside down if flying away.
That answers my original query in the OP, thanks. I'll have to give it a try and then record a gameplay video, once I've had a bit of practice.

Download those from JASPP, if you haven’t already, and use “Boot floppy” from the ADFFS Filer.

It's the 26 bit compatibility that I am stuck on.
ADFFS handles that, provided you're either booting JFD images or manually using the correct boot script.

Is there a specific game you're having issues with?

I now have a original of the final release, but I'm unsure the default world on the DATA disk is unaltered. When loaded there's a lot of pre-build cities and it starts with 20+ mins on the World Clock.

I'm after an ADF image of the DATA disk to compare.

Re: Bug in FileCore background transfers pre RISC OS 3.5

Its possible it's actually a foreground transfer that's not had the background transfer bit cleared. Foreground scatter lists aren't terminated in the same way background lists are, relying on a 0, 0 pair instead. After further testing, a possible trigger for the issue is when the complete file bein...

Re: Archimedes Iomega ZIP drivers

The memory Error possibly means what it says. During parts of the boot sequence the RMA can’t be dynamically resized. This is normally got around by oversizing the RMA early in the boot and then reducing it after. I would guess Fancyboot doesn’t do that, so it probably just needs the RMA increased v...

Re: Archimedes Iomega ZIP drivers

The ZIP Filer is probably starting the Wimp, try just “*RMLoad !Zip.iZipFS” instead of running the Zip app.

I don’t have a ZIP, so you’ll need to do some trial and error to see what you need to load for the ZIP to be accessible.

You'll need a bootable floppy (*OPT 4,3) with the ZIP drivers copied to it and a !BOOT file in the root of type Command. Within the !BOOT file load the ZIP drivers and then boot from the ZIP, something along the lines of:
