Re: Spheres of Chaos

I've not spoken to the author to see if they purchased the rights, if not, as it was previously a commercial release permission will need to be given by the rights holder before we can release a floppy image. That said, I believe I allocated an ID for the newer version so it may be possible to imple...

Re: ADFFS 2.20 released

You have uploadad an old version, 2.20, dated last year, instead of 2.40 :P This was the last fully tested release, the current versions are still in beta. There's a long list of issues to resolve, features to add, and all four versions of ADFFS will need thorough testing on all hardware platforms ...

I've done this for BlowPipe and sure enough it now works, the updated Obey.zip is on the dev site.

Re: ADFFS 2.40

BlowPipe is the closest to working, the only problem is a piece of code that tries to write to page zero. This problem only occurs on RO5, either IOMD or ARM11. The sequence of events leading up the issue are: 1. RISCOS calls the EventV handler in BlowPipe on VSync (Event 4) 2. Within the EventV ha...

ADFFS 2.40 beta

A few more games working on the Pi / StrongARM and preliminary support for RO5 IOMD. To force your Pi to 50Hz, edit config.txt on the DOS partition and add the following lines. Uncomment one of the hdmi_mode values: hdmi_ignore_edid=0xa5000080 hdmi_group=1 # #576p @ 50Hz #hdmi_mode=17 # #720p @ 50Hz...

Re: ADFFS 2.40

I've tested all the compatible games: no regressions detected :) Excellent, I'll release it shortly then. -Heimdall doesn't crash anymore on map sequence! You can move between the islands freely now! But it won't detect second disk when I change it. The hourglass appears, but it keeps asking again ...

Re: ADFFS 2.40

I've made quite a lot of changes, including several instructions encodings and the way IRQ's are entered/exited. Just need to do a final check that everything is still working, then I'll release it before I start work on IOMD 32bit. It's on the dev site if you want to test, along with an updated obe...

Re: ADFFS 2.40

With the latest ADFFS500 and obey, Freddy's Folly works. Good news. And Cannon Fodder shows intro! War.. never been so much fun! :P Music in the intro has gaps: it sounds well, but samples seem to be out of sync. It's because the inbuilt tracker doesn't take account of the buffer size the system pr...

Re: ADFFS 2.40

As soon as I click "BOOT FLOPPY" and then "YES" in the confirmation menu. It sounds like the game is missing a requirement, rather than an issue in ADFFS. I've analysed the Freddy's Folly code and have rewritten the Boot script accordingly, could you grab the latest ADFFS500 and...
