Re: Interdictor on RiscOS 3

I'll have to check, but I recall seeing something similar when testing and possibly implementing a bug fix in the boot script. I may also be setting OS emulation to 2.0, in which case it's issuing an OS call that changed behaviour in RO 3.x

Thanks for the report, I’ll investigate and get the issue resolved.
Now fixed, if you want to switch to the packaged version. The game randomly performs disc protection checks whilst you’re playing it.

mounting the floppy image in ADFFS and selecting "boot floppy" works fine, the Packman version crashes randomly.

Re: Boot floppy

What have i to do? I don't want to crash my new old machine. “Boot floppy” is an option on the ADFFS Filer icon menu. After you’ve mounted the floppy image, just select Boot floppy from the menu to run the game. Quite a few of the older games mess about with BIOS setting and Unplug Modules, by usin...

Re: Thundermonk HELP!

I have thundermonk for my old Acorn but that’s just packed up and thought instead of investing in a new one that I can get it to work on my IMac or laptop PC. First off is this possible? Of course, you'll probably want to download Arculator for PC. For Mac it's not so simple as you'd have to compil...

Re: Fire & Ice (1995) (Warner Interactive Entertainment)

Could this be down to copy protection? Just a thought. Any theories would be welcome. :) That is indeed the copy protection kicking in. If you use the JFD with ADFFS, it should work okay. I think at the time I recorded the gameplay video, an update for another game had broken it, so I should probab...

Re: Asylum RISC OS 5

I compared against a A310 and it is slightly slower. Having debugged the code, the music speed is set via Sound_QTempo which is being affected by the RISC OS OS emulation in ADFFS. Change "ADFEmulateRISCOS 3.11" in the !Run to "ADFEmulateRISCOS" as a temporary fix, to turn off the OS version emulati...

Re: Asylum RISC OS 5

When I get a chance, I'll do a side-by-side comparison between the Pi3 and an original Archimedes to double check the playback speed.

I suspect the tracker is hooked into VSync, so it may sound slow compared to emulation or RiscPC etc, but should hopefully match an original Arc.
