People who want to play Archie games with the MiST could consider this.
Since it appears that the Archie core runs at about 9x% of an original 8 Mhz Archie, you could find it interesting to replace the soundtrack player routine by the fastest available.
Most good games (and demos) used the QTM soundtracker.
It can be a good idea to replace the QTM player module in the games and démos by the latest one.(V1.45)
It's been continously improved and made faster over the years.
You could gain the few CPU % needed for your games or demos not to slow down.
You can download QTM from :http://www.phlamethrower.co.uk/riscos/qtm.php
Download the file, unpack it on the Archie, and find the QTMTracker module.
Now in the games you want to play, double click on their icons with SHIFT pressed to open the main folder, and double click on the various folders to see if you've got a QTM module.
If so replace it with the latest edition (rename it if necessary).
You can also edit the boot file or run file to directly check if the game will load the QTM tracker.
In the thread I see sbdy wanted to play Xenon II (awful, to me, again one of this poor rushed-in conversions from the Amiga).
There are 2 versions : the original one with 4 channels sound and music (it doesn't use QTM IIRC)
The second edition, distributed freely on an Acorn User diskette, with the ability to use the 8 channels of the Archies, to get 4 channels for the tune and 4 channels for the sound effects (it is intended for machines with an ARM250 or ARM3).
You can select either 4 channels or 8 channels by editing the boot file.
I recommend you use this version, with 4 channels selected, and again with the latest QTM V1.45
