Re: Disc errors with adffs?

I'm using this version, too, https://www.4corn.co.uk/archive/acornc5/Acorn-C-C%2B%2B-discs.zip in particular. I've just tried installing this and it installed okay for me on both RISC OS 3.11 and RISC OS 3.71 using ADFFS to mount the images. I did have to install Uniboot and install it to RAM: othe...

Re: Disc errors with adffs?

I guess it depends on the version, the installer with the version I have definitely requires the 177x disc controller to detect the disc change because it hits the hardware directly. A RISC OS 2 era version by any chance? RISC OS 3 added a legal method to detect the floppy disc controller. I can't ...

I'm not sure if this is an issue with the Acorn C/C++ installer or ADFFS, though. I could try writing to real disks, but I have not found a tool for this that actually works (I found two - one of them would not start at all, the other would write disks that are unreadable after writing them).

Re: Disc errors with adffs?

One more problem I have though is with the Acorn C/C++ compiler: When I run the installer, it tells me to insert disk 2. Once I do that, I get a modal popup to insert disk 1. Since I now learned that I can switch to the first disk with Ctrl-Shift-F1, I tried that, but it did not work. Ah, the bane ...

Are the ADF's complete? The file size should be C8000. I've seen quite a few truncated ADF's, particularly in the TOSEC set. Some are truncated on purpose to fool disc protection, but quite a lot are simply bad images. Where possible you want to grab the JFD versions of games from JASPP. We can't cu...

All games can be made to work without messing with the configuration, so I would advice leaving your machine as-is with ZIDEFS as the FileSystem if that's your primary boot. Without sounding like a broken record, either image and use the floppies with ADFFS if you have 4MB or RAM, or use ADFFS and t...

This was one of the pre-reqs for RISC OS 3.20. Although that's some way off due to other issues, this would allow RISC OS 3.11 / 3.19 to be patched and tested on physical.
