Sadly, not. This core remains the last "big" one on the 15 kHz frontier. Its output is not that simple but I hope one day somebody will tackle it too.

dbr wrote: ↑Mon Jul 04, 2022 12:20 am Also wondering if anyone remembers an old Archimedes game. I used to play it at school but cant remember what it was called! It was like a top-down maze kind of game. I think it was a medieval fantasy theme, or something similar, with knights/swords, etc. I could be wrong about that. I remember it being pretty colorful, and think it was almost like an RPG where you would collect keys and things.

Any ideas?

Btw, if anyone was wondering -- I tried the RISC OS 4.02 and RISC OS 3.70 ROMs to see if they work -- they do not. I kinda thought they would, since IIRC they were compatible with the older Archimedes models, but I expect I'm wrong.

RISC OS 3.70 - 4.00 are for the RiscPC or A7000 series, these were later machines. The Archimedes series (A3xx up to A5000) support up to version 3.11.

In reality up to RISC OS 3.19, that's the German version.

And no one has ever translated 3.19 rom into English?

Just checked out the latest core (Feb 21st). It seems there have been a few improvements, but 15KHz monitor support still seems broken so I'll have to stick with an old version on my setup.

Has anyone managed to get this core to work on a 15KHz monitor with the latest build?

Paul a workaround is to edit your mister.ini file and put this at the bottom:
[Archie]
video_mode=640,6,56,66,224,14,8,18,12000
vscale_mode=1

Edit: Games do not work as they often launch their own special video modes which the core scaler settings do not seem to obey. Hrm.

You must also in screen settings, first set "supervga" with automatic mode type detection turned OFF, as well as automatic mode selection OFF.

[ao486]
video_mode=640,6,56,66,224,14,8,18,12000
vscale_mode=1
-works to force the PC core to 15khz as well. Text is a bit compressed and off at first, but games look brilliant. Archie's text looks spot on.

I have a bunch of files I'd like to copy into a hard disk image I can use with the Archie core. Is anyone able to share the rough process or any tips? Thanks.

I've used OpenRiscOS on a Raspberry Pi

ARM2, so A3000, A310, A420..

I would be nice to have an ARM2/ARM3 option, so I can run some more old scene demos

Is there a way to get the "|\" key and the "£¤" key on this core from a standard keyboard?

The \| key should be available in most keyboards; for me it's to the left of the Return key. As for the £¤ key, US keyboards don't have enough room for it, but British and most European languages keyboards do have an extra key. That needs a change in Main_MiSTer, though. Archie is the only layout that doesn't have that key defined.

This:

        NONE, //86  KEY_102ND

(line 912 as of this writing, but that can change between versions) needs to be changed to this:

        0x1d, //86  KEY_102ND

The same key was changed for most cores long ago: https://github.com/MiSTer-devel/Main_MiSTer/pull/172 but Archie and Amiga have special keyboard handling; Amiga already has it defined, but not Archie. That's why it still doesn't work for it.

Maybe someone can submit a pull request with that change.

Edit: The numeric keypad # key has a similar problem - there's no room for it.

Game compatibility for this core seems to be very hit and miss. I spent most of this afternoon going through my collection, and many of the best games on the system don't work (e.g. Bug Hunter 2, Fervour, Inferno (Paradise), Overload (Paradise)), and even when they did there were often technical issues (Legend of the Lost Temple, Zelanites). I also had some issues with keyboard input. If a game uses Z & X to move left / right, inputs seemed to be not always registered, and sometimes keys would stick or act erratically. Not had this issue on other cores so it's not an issue with my keyboard. Additionally, many Archimedes game rips use jfd or apd format disc rips, which this core doesn't support.

Can't say I put this core through a stress test, but your issues surprised me a bit. I could run Bughunter 2 and Fervour and play those games on the Archie core. I don't have images of the other games you mention. Note that I do use an older core version v201101 because that supports 15KHz monitors.

What issues do you run into if you try to run these games?

The traditional way of reading jfd or adp images on an arc is to use !ADFFS on the Arc, which I use on this core and works fine. Would be cool to be able to use the format natively from the MiSTer menu though.
