An interesting one to fix...it changes palette part-way down the screen and attempts to turn the video off a bit further, to hide what looks like code in the video memory.
It works under RO3.11 emulation with monitor type 0, but fails miserably on monitor type 4 or RO above 3.11. Unfortunately it doesn't work on RO2 to test on my analogue A310.
I was testing the version in PIAS1 disc 1
