Asylum RISC OS 5

Ah those, i did try those settings but they had no effect.

What is the issue exactly?

[hydro]

The music is a bit slower as are the sound effects.

[JonAbbott]

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.

I played that game for years on real machines, i am very sure it is slightly slower, doesn't effect the game play though.

[JonAbbott]

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 emulation.

Ah cool, i have spent years messing around with music and mixing as well, i was sure i wasn't wrong but nice to know my memory worked! Thanks for proving my theory, in game music is super fast though so i guess i will disable that until you figured out how to fix that.

There is a new error with the latest 5.29 ROM (not ran the game for a bit)

Statis : Unusual DMA buffer length - execution speed will be reduced

On the Pi3? I'll update and test at some point. I don't recall if that game is using my updated Stasis Module or an embedded one, I suspect it's the former as ADFFS spoofs the DMA buffer length.

I have been using a Pi 4 since Sprow got USB working, i could try later on an older Pi 3, i have one kicking around idle.
