DKC2 sd2snes bugs (no opening title sound)

Ok experiencing a very odd bug/glitch/issue. On snes9x I have absolutely no issues with sound. However, on sd2snes i get no opening audio (can actually hear a pop were it seems to try to load the msu) and then like dampened spc there after. I have been testing to the point I patched four separate complete folders and placed them in different locations on the sd2snes to keep track of them and discovered something truly weird. I got the audio to actually load/work in one folder but if I try to move it the msu patch no longer works. This defies what I understand as the patched file and its contents are in their own self contained folder and just moving that folder inside another shouldn't have any effect (as it never has for any other msu patched game). Any insight is appreciated.

Hmm, i think considering the popularity of this game, somebody would have complained months ago if there were sd2snes issues.

I have the following advice, requests:
- somebody else with a sd2snes can you countercheck?
- there are 2 versions, 1.0 and 1.1, did you check whether both have the issue?

Other than that.... it's not my code and we have no source from mattrizzle. Furthermore, tracing sd2snes bugs is impossible, it's only anticipatable. I'll look if above questions are answered, nevertheless

Must be a firmware issue then I'd assume. I am almost positive (would have to test it again ugh) but I believe I have had both 1.0 and 1.1 working so long as they aren't in the one folder. What baffles me is that the aforementioned folder has almost all of the MSU patched games i have in it and they all work.

Matt uses a different coding style but checking his code:

$B5/8536 8D 04 20    STA $2004 ; store pcm #
memory is in 16 bit mode, so 2005 also gets 00
...
$B5/84EF AD 00 20    LDA $2000
$B5/84F2 29 40 00    AND #$0040
$B5/84F5 D0 F8       BNE $F8 ; wait for pcm loaded
...

and all else is inside to ensure sd2snes compatibiltiy... so from briefly looking at the code I don't see anything weird.

we need to figure out now whether you are the only one having the issue, means somebody else must countercheck on sd2snes.

Well thanks for the swift replies. Like I said I do have it working, just not in the folder I'd like to have it in so no rush or anything. I would love to know whats going on though. I even had two exact copies of the subfolder and swapped between the two locations and it only didn't work in the main msu folder.

Ah I see. So if you have it in a specific folder it works in sd2snes, but if you e.g. move it in a subfolder, it won't.

That's no issue with the code then but with sd2snes itself and you need to ask Ikari.

What is the best way to contact him?

@Highblade7777 Can you provide me your sd2snes firmware used? Also the CRC checksums for the ROMs you used (to make sure I’m using the same ones). This way I can test on my sd2snes to see if I encounter the same issue.

You say this happens when both patched DKC2 ROMs are in the same folder on the SD Card?

@Highblade7777 Can you also provide an image of your folder structure where DKC2 is kept too?

I should be on the current rev 1.9 I'm not sure how to get the checksum for you.

Ok here is a start, currently the rom is in the Platformer folder but if it is moved to my -Top 20- it no longer works with msu audio

Is this the checksum info?

I sent you some mail addresses from ikari via pm.

What might be a reason is that you maybe have too many folders now containing dkc2 on your sd? Ok, chance is little but maybe it tries the msu from a main folder and you load the game from a subfolder or something. Try maybe with only one dkc2 folder.

@Conn Yeah, I agree with you. Maybe the FAT32 character limitation has been reached (including the subfolders).

@Highblade7777 I would follow Conn's recommendation (lower your folder characters, keep names folder simple).

Only one copy atm and it will still present the same issue.

@Highblade7777 Ok, so your DKC2 folder is in the:

- Top 20 - Hall of Fame

What is the DKC2 folder called, attempting to reproduce the exact same conditions. I will need to get the latest sd2snes firmware as well (still running the beta SDD-1 one).

@Highblade7777 Best way is to test different firmwares (work your way down). Just rename your sd2snes firmware folders accordingly.

I think you both are onto something. I do have long names for virtually all my files. Kinda OCD that way

@Highblade7777 I do know FAT32 has a 255 character limitation (including sub-folders). It will do weird things to different software applications when this limit is reached.

For example, your current folder

x:\- Top 20 - Hall of Fame (uses 23 characters)

* below as another example, keeping your main folder
x:\- Top 20 - Hall of Fame\Donkey Kong Country 2 Tropical Freeze Edition (uses 68 characters)

and so on...

So within each folder I need to make sure that the subfolders that hold each game add up in total among all games to less than 255?

@Highblade7777 Yes, you got the idea. See the example I gave in my previous post (updated it while you responded).

Yeeeaaaah sooo this is how the top folder looks. I think like 30 characters are used just for the first game...

@Highblade7777 Below is a video I captured from sd2nes with firmware 1.9.0 on my original SNES (both DKC2 versions).

sd2snes 1.9.0 DCK2 v1.0 and v1.0 Example

@Highblade7777 Here is another video example using a similar filename structure from your last image post.

sd2snes 1.9.0 DKC2 1.0/1.1 Example (Longer File Names)

Ok, trimmed all of the file names patched a clean 1.1 rom and applied the appropriate patch. I'll test this when I get home.
