Welcome. It's rather quiet around here these days, as you've probably noticed!

I don't know if you're aware of my website: http://www.proggies.uk/

You will find links and various other resources there.

New BBCSDL games website/web page?

I'm thinking of adding a new section to my website called ' BBCSDL Games ', dedicated to games (and perhaps some other software - libraries, etc.) written for the cross-platform version of BBC BASIC. Would anyone reading this be interested in contributing BBCSDL-based games? Contributions would NOT ...

Re: Dark mode for IDE

I was using BBCSDL on Linux Mint (64-bit) pretty much all night in my dark little shed, and the 'Dark Mode' was deeply appreciated! So much easier on the eyes. With my eyes adjusted and relaxed to the dark theme, when I then occasionally had to open a PDF file (or browse a website) it was like sudde...

Re: Request by Richard to return

I had considered myself a 'retired' member (concentrating almost solely on RISC OS-based projects), which is why I didn't respond to this thread, but then I went and posted that plasma demo.
