Interesting to see it works on OS6. Encouraging. As for the A9, this
error may be connected with a piece of ARM code to fade a 16 colour
screen, from a 1990 issue of Micro User.
You've mentioned the palette restoration. This raises an issue which
I've found really irksome. There's never been, to my knowledge, some
kind of repository/wiki for Acorn games programming, which answers
what I feel are nitty gritty questions, such as:
- how to restore a 16 colour palette reliably
- how to perform proper memory management (loading, and removing
modules, restoring wimplslots)
- how to fade a 16 colour display.
- how intermediate RISC OS developers like me who have created games
for free, can get our work to be compatible on all these systems with
minimum fuss.
RISC OS is supposed to be easy, yet knowledge certainly in cyberspace
is rather lacking. I've given myself 2 weeks off work, and I've spent
too much of it looking around for these answers, and am left
frustrated at the lack of progress.
Info like the above could encourage others to get their games
compatible.
