About a couple decades back I wrote a graphics/game programming tutorial (https://solhsa.com/gp/index.html) based on SDL 1.2. It used to be a major driver of traffic to my site, so one or two of you may have come across it.
Time has passed and because of the old SDL (and old compiler suites) the tutorial has been more or less obsolete.
I've started to revamp it - not completely rewrite, as it still uses much of the old material (as basics don't really change). I'm basing it on SDL3, so it should be relevant for a while again. Well, as relevant as plotting pixels goes.
As of this writing the first 10 chapters are here: https://solhsa.com/gp2/index.html
If someone does drag themselves through the tutorial, feedback and inevitable bug reports are welcome.
