Known issues

Battle Chess - !Battle.NOTHING won't play (worked around I believe by changing the !Run script)
Manchester United - !!MUFC!!.ZilchMus won't play, so the music doesn't stop when you start a game
Lemmings 2 - hangs during loading
Nebulus - music isn't starting (it was in 0.05, so I've broken something)
Quest For Gold - samples are the wrong pitch
The Krisalis Collection: Terramex - no sound when using the old music


Outstanding development

Mus_Patch - Requires QTM extending to support this (entry R0=songpos, R1=songpos). When songpos hits value in R1, jump to songpos in R0
Mus_Sector - Possibly protection related
Mus_Effectcontrol
Mus_Instruments - Requires QTM extending to support this (no entry values, exits R0-R3 containing the instrument no. currently playing in channels 1-4)
Mus_FXonly

Manchester United - !!MUFC!!.ZilchMus won't play, so the music doesn't stop when you start a game

This isn't the cause of the issue. I've modified the code so no error is reported when loading this file and the music still doesn't stop. Will investigate further.

[JonAbbott]

The reason the music doesn't stop when starting a match in Manchester United is that it issues the following calls:

Mus_Sector &38E, &BB, 0 (which calls the Teque_Hackers SWI in TeqMod)
Mus_on

I believe this reads 187 (&BB) sectors (95744 / &17600 bytes) from &71C00 on the disc, which must be a music track. I'll disassemble TeqMod and see if Teque_Hackers can be implemented in the shim.

Another interesting observation is that when on the menu it issues Mus_Laidback after every animation change, I wonder if this is used to slow the game down.

- QTM is now initialised to 8 channels as Mus2QTM initialises (fixes Omar Sharif which doesn't have music)

Try using QTMv1.44a and only 4 channels again, with QTM_PlaySample R0=-1 - this should now work perfectly!

Battle Chess - !Battle.NOTHING won't play (worked around I believe by changing the !Run script)
Manchester United - !!MUFC!!.ZilchMus won't play, so the music doesn't stop when you start a game

These might/should work now with QTM v1.44a

Mus_Patch - Requires QTM extending to support this (entry R0=songpos, R1=songpos). When songpos hits value in R1, jump to songpos in R0

This will need big work... Which games does it affect?

Mus_Instruments - Requires QTM extending to support this (no entry values, exits R0-R3 containing the instrument no. currently playing in channels 1-4)

Try using QTM v1.44a SWI QTM_ReadChannelData

I actually preferred it as it was, I'll put both modules up so you can compare and see what you think. BlowPipe is the worst case scenario, so give that a go.

I'm not sure which games use it, it's been there since MusMod1 so must be there for a reason. I'll retest all the games and see if any call it.

Try using QTM v1.44a SWI QTM_ReadChannelData

Now implemented and working just great. I've used this to also implement Mus_Effectstatus correctly. I'm just trying to implement Mus_Sector and will get 0.07 up later (in 4 and 8 channel modes so you can give your opinion)
