Switching Mods #3

Closed blitmaps closed 5 months ago

blitmaps commented 3 years ago

This player is performing very well, but I'm having trouble switching mods...

I am just removing the interrupt and restarting the configuration, as I change mods two or three times. When I build, and one of the mods that I play first plays fine, and then the second seems to play the track but the instruments are just random noise.

Am I doing something stupid?

xdef    _play_voyage_music
_play_voyage_music:
            ; Stop the playing routine
            jsr LSP_MusicDriver_CIA_Stop

        ; Init LSP and start replay using easy CIA toolbox
            lea     incbin_VoyageMusic_start,a0
            lea     incbin_VoyageBank_start,a1
            suba.l  a2,a2           ; suppose VBR=0 ( A500 )
            moveq   #0,d0           ; suppose PAL machine
            bsr     LSP_MusicDriver_CIA_Start

            move.w  #$e000,$dff09a
            rts

it's because of a bug in the relocation "is done". I'm about to fix that in next version. Before that, as a work around you could comment the lines "tst.b m_relocDone(a3)" and "bne.s .skip"

That is fantastic - fixes the issue perfectly!

Hey, is there a workaround for changing back to the same mod? The workaround above works perfectly for A->B. If you go A->A or A->B->A , the second A does not play correctly. (sorry, I am not super skilled at assembly at this is highly optimised, but it looks like allocation is happening based on the mod input).

the reloc flag has been changed recently in v1.10. the A->B->A pattern should work now
