Japp, and a complete description what is needed. But I can also play there by unlimited life cheat and fast forward

Your last fix pretty much put this game in the finished category. Well done.

I just checked your new pcm set:
PCM 'Darius Burst' set ver3 (PepilloPEV):

Unfortunately track 107 is missing in this set, means the normal bosses should be muted

I'll fix when I get a chance. I'm not at home at the moment

Taken care off. The missing track is now part of ver3 (as it was originally intended).

Really nice !
thanks !

On sd2snes sometimes the opening song and title screen don't play. The music of the level bosses does not play. When I got to the 4th stage the music didn't play.
Does anyone know what the problem could be?

It's important to know if you use the last firmware for your sd2snes ??
If it's the last firmware (beta for now more than 6 months.. yeah the programmer isn't very active..) , try to revert to the previous firmware.

I tested with firmware 1.10.3 and with beta 1.11.0b1. With both FW the result was the same.

Pepillopev (the author) is very precise when it comes to real hardware testing, so the problem is probably on your side. I still have no sd2snes myself but usually relikk knows advice how to tinker the adjustment...?

I've never tested it on SD2SNES, but I presume that Conn is referring to the "in-game hooks" options and that they should be turned off (if they aren't already).

I tested with hooks disabled and the problem persisted. Tested with 2 different micro sd cards. On snes9x it worked perfectly, but on sd2snes pro it didn't work properly.

@Conn Running a quick test, I was able to reproduce the no music on intro problem on my Sd2SnesPro by just pressing the reset button or leaving the game running on its own for a few minutes. Also, noticed the music does not always play in demo mode, most of the time. One of the demo stages does not play music but the rest play fine. So there is something going on. Unfortunately, I just do not have the time to troubleshoot this and find the cause.

If it is working on snes9x w/o issue but not on FxPak/Sd2snes; my suspicion points to 'msu status ready' code not properly implemented on my end. I would have to hunt the source code down. I recently redid my PC after a massive hard drive crash. I have backups; just have to sort through my crap to find it.

@pev
Oh l see. There's a ASM file inside the patch folder, maybe this helps, so you don't have to find it on your hdd?

Thanks Conn. I must have overlooked it. I will look into it as time allows. Right now work is a PITA. Don't have much time anymore like before. Worked picked up a lot after Covid restrictions were removed in my area.

I'm on vacation right now, even abroad after 2 years covid. On a short glimpse (only viewing the asm)

The problem should be very easily fixable:

Code:

   STA $002004 ; need to be $002004, will not work right if just $2004
   PHA
   LDA #$00
   STA $002005 ; need to be $002005, will not work right if just $2005, there is no STZ $002005
   STA $002006 ; need to be $002006, will not work right if just $2006, there is no STZ $002006
   PLA
loopTitle:
   BIT $2000
   BVS loopTitle ; track not ready

You notice that we have long addressing ($002004, instead $2004), so also the loop title (bit $2000) must be adjusted to long (this also explains why it sometimes works and sometimes not.
So:

Code:

loopTitle:
lda $002000
AND #$40
BNE loopTitle

should fix the problem. Let me know if you want to try that yourself and have the time to update or whether I shall take care of (it's 10 minutes imo)

@Conn Ok, revising the 'msu status ready' check with correct long addressing helped some. There is still issues with mute 'intro' after one specific demo stage plays on FxPak/Sd2Snes.

@*ka I saw your post on Discord asking others to chime in for the Darius issue. Try this patch and let me know how this works on your sd2snes.

@Conn Only other thing I can think of is the NMI mute timing. I recall this game, a NMI was used to mute the APU after it init. I wonder if it APU init phase is not given enough time for msu to play on intro.

I tested the patch. Stage boss music now plays normally. The music of the stages and title screen sometimes doesn't play, it's random. The first stage was without the FX sounds.
I recorded two videos showing how it ran here.

At least some progress I do not know how to help further since I cannot test on sd2snes (have none) and if the bug doesn't occur on emulator I cannot trace it
nmi as pev suggested might be the reason, but I cannot, as said, test it...

I may have an idea:

Code:

$0F/FB2E 48          PHA                     A:8000
$0F/FB2F A9 00 00    LDA #$0000              A:8000 
$0F/FB32 8F 07 20 00 STA $002007[$00:2007]   A:0000
$0F/FB36 AF C2 01 00 LDA $0001C2[$00:01C2]   A:0000
$0F/FB3A 22 C1 FB 0F JSL $0FFBC1[$0F:FBC1]   A:0001


$0F/FBC1 8F 07 20 00 STA $002007[$00:2007]   A:0001
$0F/FBC5 6B          RTL                     A:0001

What's happening here is that $2007 gets muted and then written again some ops later. This does not work in sd2snes.
Please check attached patch, I nopped it out

Ok, looks like you nailed it Mr Conn. So far, no random muted intro or demo game play on my sd2snes.

I played around a bit and now it's working perfectly on sd2snes pro.
Thank you very much.

Nice - RH is also only guessing to me
I renewed the patch to 1.3 in OP. Now back into retirement
