So, the GPU is an X1600 series. I forget right now if it's a 1600 pro or a 1650 pro. I think the 1600. It works fine with Mint so I guess my next step is to copy over the config from there although from memory, I only specify the monitors because at the time I was using a 4K monitor and having problems (I now use a 1080 monitor for Mirari). I do have an HD6570 I can put in temporarily after the weekend. Longer term that's not supported by MorphOS at this time.

The problem with Void (downloaded your image) is that despite being gzipped and around 4GB it downloads 13GB as though it is uncompressed and once downloaded the MD5 sum is not correct. It also didn't work after writing to USB (gparted did not recognise it). The other thing is that it isn't really going to prove much anyway as the contents will be too old to prove whether there is a problem with current SDL2 in PPC32 in general (unlikely) or if it is Mint specific.

The following happens very often:

The server sends:
This means:
• Server compresses transport-side
• Proxy or client automatically unpacks transport-gzip
• Only the .tar remains

This is technically correct HTTP behaviour.

The file then looks like this:
The file name remains, but the gzip layer is gone.

Solution: Prevent transport compression:

If you use an old Radeon graphics card then some 3D games don't work reliable on Linux. For example SuperTuxKart 0.7, 0.8 etc. STK 0.7 and higher needs at least OpenGL version 3.0. You can try STK 0.6.2a with old Radeon graphics cards.

For example STK 0.6.2a with an ATi Radeon X1650 SE (RV516, OpenGL version 2.1):

Unfortunately, unless I'm wrong, and there's a way to get up to date versions of software onto Fienix and Void, they aren't any use to me?

Like I say, there appears to be an issue with SDL2-devel on MintPPC and to establish whether the issue is specific to Mint, I need to try the same version or newer on another distro. If Void hasn't been updated since 2023 which is my understanding, then it won't help me because if things work then I won't know if it's because they're older and the issue didn't exist then or if it just works on Void.

Copying my X config over from Mint to Chimera leaves me with an X server that won't start as it can't find the radeon driver.

I guess for completeness I can try to boot Fienix and Void just to see what their versions of SDL-devel are.

Managed to get Void downloaded and installed to USB. Unfortunately while a simple test of SDL2 (building an app that displays a window cleared to a specific colour) works fine, it doesn't really prove much as the version of SDL2 is some years behind the one in Mint. So I have two choices, go through the pain of trying to build current SDL2 from source, or have another go at Chimera. I'll go with the latter for now.

One question, is the legacy radeon driver built into the kernel? I think I'm still using the 6.17 kernel that was on the SD card of the Mirari when I got it. X11 complained that it couldn't load it.

Yes, it is integrated.

Great! Did you download it with the following command?
