I'll need to either patch BASIC, or check if R14 is within BASIC and the previous instruction is MOV PC, Rx at the SWI vector. Tried this earlier and it breaks BASIC in various places, so is a non-starter. The Dungeon is failing because it makes assumptions about the position of the Voice name in a...

I've got it to the menu on RO5 SA, its failing beyond that because BASIC's SYS command isn't being intercepted and hypervized. I mistakenly thought BASIC used OS_CallASWI for SYS but it instead writes an SWI instruction to memory and branches to it. I'll need to either patch BASIC, or check if R14 i...

A more future proof method would be to modify the 'janitor' Module to handle re-entrancy on FileV and call OS_File, so it's not dependent on the OS behaviour - essentially how it should have been written in the first place. This isn't particularly complex, however at the minute there's no means to ...

Unlikely as the protection doesn't play well on RO5, the game essentially takes over all filesystem vectors and decodes all reads. Any read to a file other than one it's expecting, or any * command causes the protection to lock the machine. I had a look at the protection this morning to see just ho...

Inferno hangs here after I press 1 to start game. Wimp support may have broken it, it's broken a few games for no apparent reason. Its looking like it may be a compiler issue, but I've not managed to track down the root cause yet. Will we see "The Dungeon" supported soon? Unlikely as the ...

The latest obey.zip / adffs500 Module on the dev site get Arcade 3, Pipe Mania and Spheres of Chaos working on the Pi. It now has feature complete 26bit Module support, basic Wimp support (which needs debugging on the Pi, it's working on SA RO5) and SWI flag preservation.

I've posted a video of Minerva's Battle Tank on YouTube, having spent three days fixing most of the issues with it: Uses *ScreenLoad which on RO2 preserves the cursor state, on RO3.5 and above this is no longer the case Speed regulation is done by small code loops, designed for a non caching ARM2 Th...

LDR's are interpreted only once to see if they're touching Page Zero, if not the instruction is copied. Yes it's hideously slow, hence why I want to get rid of it. I think the way forward is to switch the CPU to Abort on misaligned read/writes and interpret them when they trigger an Abort. Ironicall...

ZIP up your !Boot.Loader directory and email it to me so I can try it on my Pi: jon at jaspp dot org dot uk

Another think you can try is a clean boot, by holding SHIFT during the boot.
