What DISP_MODE are you using?
Hi,
Mostly Mode 6, but I also tried Modes 2 and 3. All gave the same results. It DOES work in Mode 0, so it would seem that the problem is with the 16-bit colour modes.

I'm currently collecting error reports for a "final fix" mid January, that will also make the interlaced mode work on more platforms and a slightly improved colour threshold between pages (I have a version here that shamelessly steals the IPC comms code from SMSQ/E to make the keyboard work (by bypassing the ROM) on Minnie ROMs.

I finally came around to
Publish the source code on Github
Fix some nasty bugs
Implement proper on-the-fly Floyd-Steinberg dithering for MODE 8 graphics - looks much nicer now on a real QL. (activate with "-f")
(I'm pretty sure I meant "mid January 2022" in my previous post. Thus, I'm only 4 months late...)

Downloaded and tried it on QPC II yesterday evening. Never played The Pawn before, thank you very much for this excellent contribution to the QL community!

You mean, like in source code shared on GitHub or something like that?
It's in ql_c function RGB8ToQLiFS

Amazing work! Unfortunately I'm poor in actually playing, but it is very impressive!
