Turrican 2 MS-DOS AGA conversion

[Muzza]

I used the Turrican 2 WHDLoad source for the DMA delay code. It looks like this:

DMADelay:

     move.w  d0,-(a7)
    move.w    #8,d0
.bd_loop1
    move.w  d0,-(a7)
    move.b    $dff006,d0    ; VPOS
.bd_loop2
    cmp.b    $dff006,d0
    beq.s    .bd_loop2
    move.w    (a7)+,d0
    dbf    d0,.bd_loop1
    move.w    (a7)+,d0
    rts

Huh... stupid me didn't notice that this DMAWait code was already in there, but commented out (and missing a few bits). I had added it new using the WHDLoad patch code as reference as to where to insert the DMAWaits.

The two differ slightly (WHDLoad has an extra DMAWait and calls them at slightly different positions), but both appear to work from my testing. I've changed my code to match the Eagle Player one as it seems a little neater.

For me looks good, 8 lines wait. Maybe jotd can test T2 title music under EP and check if it sounds ok or not? I think it can be problem related to interrupts handling. Perhaps the only difference between T2 code and T2 AGA code is memory used for TFMX 7V replay. Chip memory for T2 and fast memory for T2 AGA.

Where can I get these from?
EDIT: Nevermind, I think I misunderstood - I thought you were saying there are special versions of the music samples that make the higher quality mixer more apparent.

There was SMC in there still, but I just fixed it yesterday. When I first implemented this, I had problems getting it working (it was early days in my Amiga programming 'career') and I compared the source from eagle player to the raw ASM ripped from the original binary and restored what I could in an effort to get things working. So I think I have a frankenstein mix of original, Eagle Player and my own efforts. My recent changes have probably restored it to be more similar to Eagle Player.
Currently I have the new mixer on a switch (currently turned off, but I'd consider enabling it if the higher quality music is worth it).

I've noticed that when emulating in WinUAE with a 68060 and chipset_hacks=0x8 there are problems with the loading and in-game music too (which use a different player). Not as obvious as the main menu but it is there.

This is fantastic, thanks for your efforts
