I didn't know if the ao486 would benefit the most from this because of the mentioned compatibility issues like Amiga disks on a Windows floppy drive. The following is all IIRC - I researched the whole stuff when looking at doing an USB driver for Acorn RISC OS floppies, probably in 2007. "Wind...

The result is that it almost works. I was able to briefly play both Lemmings and Ibix the Viking. However both of them only appeared in the top half of my screen (i.e. the whole game display was squashed into the top of the screen), and Lemmings had some flashing effects in the bottom half of its d...

You might have run into a problem of incompatible .hdf formats in specific cases - ADFS vs. Risc Developments IDE/MIST implementation. hubersn There's no "MIST" implementation. The Risc Developments ROM used without any change (I don't even know a single instruction/function in it). Yes, ...

However I was stopped dead when I found that the disks were mutually incompatible; I can't mount the Arculator disk in Mist, or the Mist disk in Arculator. I am not a great expert on Riscos, it's just something I've always wanted to play with, so I'm not sure where to go from here. You might have r...

The Archimedes is certainly a computer that you have to get your head around! Me (and others) would be very grateful if once a working .hdf full of games and cool stuff plus the corresponding CMOS and Risc version files are made could they be zipped and uploaded somewhere please. I am slowly workin...

OK. I can edit SVGAIDE.RAM file with a Hex Editor, but what value and position of 256 bytes I will must use? You can find the CMOS content definition here: http://www.riscos.com/support/developers/prm/memoryman.html#40894 Or here: https://www.riscosopen.org/wiki/documentation/show/OS_Byte%20CMOS%20...

I understand that it is the serial joystick and not the RTFM. I haven't tested it, but it is documented as "Acorn" joystick interface (i.e. A3010 type), so neither TSP nor RTFM. How many trigger buttons does it support? Two I think. But I am not aware of games that supported more than one...

I have verified that the Cataclysm game does not work in the last core archimedes_191102, it gives "Unable to move memory" error, however it does work in the previous version archimedes_190308. I found out that there are two Cataclysm versions - the original (1991 vintage) and a modern Ri...

I have verified that the Cataclysm game does not work in the last core archimedes_191102, it gives "Unable to move memory" error, however it does work in the previous version archimedes_190308. "Unable to move memory" sounds more like a RISC OS error than a core problem. The new...

Arculator v2.0 has been released, for those who (like me) switch between PC-based emulation and MIST:

Now with true disc drive noise! OK, that's perhaps the least impressive thing from the "Changes" list...

So I have an image for you to try: https://www.huber-net.de/riscos/archie1.zip The archive contains a 260MB file, and the IDEFS driver doesn't recognize the filesystem on it (did you create it on Riscdev's IDEFS or ADFS?) OK, next try: https://www.huber-net.de/riscos/idehd_archie1.zip Renamed the d...

Or configure "language" to the correct value for CLI which I don't remember off-hand. "Desktop" is "language 10". Don't ask. How could I forget...it is ⋅  *con. language 1 of course to start up in CLI (aka "Supervisor mode") on next reset. And, even...

I haven't had a chance to try on my real MIST, so a stab in the dark... hubersn It's not MiST specific, it's the same in Arculator (selected "old" FDD, then the IDE interface is the RISC Development one). Even tried to *Configure filesystem IDEFS, no change. Will try the other CMOS settin...

Renamed the disc to "HardDisc4" because I am a RISC OS traditionalist :-) (and to pragmatically avoid any hardcoded-path-problems in !Boot setup) Anything has to be done to load the new Wimp? SF3000 still complains about the need of 3.80. I haven't had a chance to try on my real MIST, so ...

Hi! I found a nice RTS game called TEK 1608: http://www.acorn-gaming.org.uk/index.php3?p=Reviews/Tek/index Perhaps it worths to test this title with the new core, although it's still commercial AFAIK... I fear it won't be worth it, since TEK is from the Risc PC generation of games targetted at the ...

Plain ADFS on Arculator. You're telling me that Risc Development's IDEFS cann...

And it needs the Toolbox modules also. So a true full UniBoot is needed. I'll do a proper HD image with all bells and whistles. And, as it turns out, it wants a later version of the Toolbox modules than those bundled with UniBoot. Well, if it was easy, anybody could do it :-) Have fun hubersn I hop...

I hope you can sort this out. The whole purpose of the IDE interface is to run SF3000 :) OK, so when I tell you that the core needs feature xyz to run SF3000 you would be extra motivated to implement it. How about networking support (Econet and Ethernet of course!), FPA10, the different joystick in...

I haven't tried - does Shift-Boot work with the core? But I am actually surprised that Star Fighter 3000 itself needs the "Nested WIMP" at all. All the tools surrounding it - OK, because they are newer developments. But the original Star Fighter 3000 ran on plain RISC OS 3.1, and it would...

Do you have an idea is it possible to upgrade Wimp to 3.80? According to http://starfighter.acornarcade.com/ it's in the UniBoot package, but even I unpacked one from the riscos site, I don't think it was successful. At least SF3000 didn't start. I will have a go. UniBoot contains WIMP 3.98 (which ...

Ok, it's done: https://github.com/mist-devel/mist-binaries/blob/master/cores/archimedes/archimedes_191102.rbf I'll write some description about the usage in the Wiki later on, now you can find a CMOS file to configure one IDE interface at boot, and a 512MB .hdf file zipped (formatted, and SparkPlug...

The original ICS ROM is 32k, how could ZIDEFS work only in 8k? John Kortink magic assembler coding? I have no idea, would have to look into the disassembly. But it would be not untypical that the 32k ROM is just ready to be burned into a 32k EPROM and in reality at least half-empty. Going into the ...

It seems the built-in IDE in RISC OS (with the 82c711 chip) works only if the FDC is also used from that chip. Yes, I think this is correct. It is either 1772-and-6551 or 82c710/82c711-all-the-way. If you want to keep the 1772 and support a harddisc out of the box with RISC OS 3.1, you'd need to si...
