Here is another version with the loader screen etc. stripped out for faster loading. There are several versions included with various latencies applied which you can choose at startup. I did discover a potential mistake in the code from when I was previously fiddling with timings which may have affected the result. In terms of timers I was already using timer 1 and the OS is long gone. If people could try on a VLSI Master and let me know the results that would be great.
I'd be interested if there is a difference between Latency '0' and '1' - these both have zero latency but slightly different instruction ordering. '24' should be more or less equivalent to the owlett code above.
Many thanks for trying to get this sorted.
I have observed more screen corruption on scrolling on this version - will have a look at this later.

Re: Acorn Island
Thanks for this. It seems to work well on my VLSI Master!ChrisB wrote: ↑Sat Feb 04, 2023 8:52 am Here is another version with the loader screen etc. stripped out for faster loading.

I only had half an hour or so to try it today, ran through the different latencies and couldn't really see any difference in behaviour. I will try and spend a bit more time on it this week to see if I can spot any issues.
Re: Acorn Island
Thanks for looking. I'm intending to produce a new version with some other fixes/changes that will hopefully resolve the corruption on scroll whilst maintaining compatibility.

Re: Acorn Island
Good to see that you're increasing the compatibility RE: crtc versions. It would be good to get a "post mortem" on your crtc conclusions once Acorn Island is finalised.
Re: Acorn Island
Please find attached V2. If this works with a VLSI 6845 (please can someone test) I'll promote to the release thread.
Changes in this version:
Changes in this version:
- Updated interrupt routines to play nicely with a VLSI 6845. This has included adding another interrupt half way down screen for my re-draw synchronisation to remove corruption on scrolling right.
- Code wrangling to make some more space.
- Added some new signs and added more information to other signs to provide more information early game.
- Swapped the name of the forests to save memory.
- Updated two mistakes in quests to indicate East instead of West.
- Clarified the next action on an early game quest.

Confirmed on my VLSI Master! Superb bit of rework!
