For some reason this patch corrupts my ROMs. Any ideas?

EDIT: Wait, this patches to Demo World 3. Whoops.
EDIT 2: Still doesn't work - freezes after "Nintendo Presents..."

---

This patch puts the SMB2 music data over SMW's music, and fills the ending music bank with FF. Unless you have extra stuff in the 70200-7FFFF and 1E600-1FFFF ranges, it shouldn't be crashing.

Oh, I designed this to patch to a ROM with normal SMW music, so the problem may lie in the high bytes of the SPC pointers. To correct this, change 2F3, 308, 319, 353, and 364 to 0E, 0F, 0E, 0E, and 0E respectively.

With my next release, I'll add a readme to the zip.

Interesting... this suggests I should list four rather than three people when asked about the N-SPC in the future...

Instead of changing every single change instrument command, you could have assembled a new instrument table that would allow you to keep the old instruments unchangedly. Bouche did that when porting the Corneria tune from Star Fox.
Oh yeah, add Star Fox and Star Fox 2 to that list.

While I, being at school, can't really get to have a look at it yet - good work.

If you want to assemble a number of premade alternate music patches, I could provide you with a number of dumps of readily converted to N-SPC Cave Story and Secret of Mana music... (while I am working on SD3, the amount of commands I have figured out doesn't suffice to create anything reasonable out of most tracks yet sadly)

---

That's odd, because upon when I tried searching for N-SPC data in an SPC dump of Star Fox, I did find the bytes that usually signify the start of the engine (20 CD CF BD) couldn't find anything that resembled N-SPC commands(track data). I thought it may have used a variant of the engine, as I know BS Mario Excitebike does, as it probably has more commands.

The only thing here is that I'm looking for music that sounds like Mario. I don't know if those do.

I figure I may as well ask you a question here, blackhole. Did you ever find the location in the SMAS N-SPC engine that tells how many tracks to allow? I've expanded the table and moved it to a different location, but any tracks with a value higher than 24(0x18) behave like track 00(nothing). Also, I cant can't pinpoint the locations of sounds written to 1DFA(Mario's jump, turning around, etc.)

How did Bouche do that? I added a bunch of old SMW instruments that didn't have matching SMAS ones to the end of the instrument table, but I never have made extra instrument tables for different tracks. I can see how it might be possible to have different instrument and sample tables in each bank, but until someone has the guts to make a patch in which each level track is in a separate bank, I'm stuck in the dark on this.

As for the marioness of music, I have some old Cave Story conversions in here... I think some of those might work, but eh, figures.

---

Yeah, Moon Song sounds like it would work nicely in cave levels.
When I heard the Hell track, it brought to my mind a type of level where Mario has to move quickly from platform to platform, with enemies coming for him in all directions. It seems to be a great candidate for the Athletic level track.

I'd like to thank everyone for their ideas, and blackhole for his SPC files! Here's a list of tracks for the updated SMB2 music patch, with tracks not currently added to/shifted in the patch in boldface:

06: Cave Prototype
07: SMK: Ghost Valley

15: Final Battle Pt. 2
16: Final Battle Pt. 3
17: Zelda 3: Death Mountain (I had to get rid of the instrument used in the final part's melody in order to make room for more tracks)
18: Yoshi's Safari: Pipe Island
19: SMW: Castle
1A: SMW: Bowser Zoom Out
1B: SMW: Bowser Zoom In

0F-18: -unused-

Title Screen/Ending Music (complete)
01: Title Screen
02: Ending Pt. 2 (Mario sleeping)
03: SMW: Rescue Egg (used during Yoshi Eggs hatching cutscene)
04: DDP: Ending Part 2 (used during enemy sequence)

Sound Effects: $1DFC (complete)
I've changed my mind. I'll add all of the SMAS sound effects back in.
4A: Charge Jump

Sound Effects: $1DF9 (complete)
1B: NES-style Stomp (Edited from Yoshi's Safari)
35: Mario kidnapped by Bandit/Toadie/Swinging ghost (SMW2)

Anything without a game title is from SMB2.

The congratulatory music from Dr. Mario might work for an underwater song, but the little virus riffs probably disqualify it.

---

Actually, the virus sounds would be fairly easy to get rid of. If you listen closely, they aren't there when the track loops around for the third time. It would just be a matter of changing the part pointers to start at the part where the virus riffs are gone, and deleting those unneeded parts. If all else fails, I could add in the SMB or SMB3 underwater music(though SMB3 music is way overused).

I forgot to mention that the only map tracks I want to keep in are the SMW2 map and the SMAS menu.

As for the Athletic music I've been thinking that Yoshi's Cookie: VS. Music C may be a better alternative. It just puts in my mind a picture of a vast area, high in the sky as many of the athletic levels are. But it also seems that it could be used, for a cold, mountainous, wintry area. I like music that sounds like it could be used for multiple purposes.

For an extra bit of icing on the cake, I could throw in the Yoshi's Cookie: Action Interlude for use in the castle destruction sequences.

This is awesome. Now we need someone to hack the bank switching, so we can add tracks instead of replacing them. I assume there's just pointers to an SPC700 program in the ROM, one for the overworld and one for the levels, and the game simply uploads the appropriate program? Expand the table to one entry per level and one per map. As a bonus, you can have longer songs, since you only need one in the bank at a time.
Though it seems to me if it were that easy, someone would have done it by now...

---

There are a total of five blocks of data, I wouldn't really call all of them programs.

SPC Pointers (in SNES format)
70200 SPC Engine/SFX/Instrument Definitions/unknown 24-byte table
2E9 [00] Low Byte
2EE [80] Middle Byte
2F3 [0E] High Byte

78200 SPC Sample Pointers/Samples
2FE [00] Low
303 [80] Middle
308 [0F] High

71AB1 SPC Music Bank 1 (Map)
30F [B1] Low
314 [98] Middle
319 [0E] High

730D6 SPC Music Bank 2 (Levels)
349 [D6] Low
34E [AE] Middle
353 [0E] High

1E600 SPC Music Bank 3 (Ending)
35A [00] Low
35F [E4] Middle
364 [03] High

The addresses above are from the actual subroutines that load in the banks. I believe the SPC engine and samples are loaded in at startup, then a jump to the one of the other three subrountines determines which music bank is loaded in. Games like SMK and SMW2 load in a default music bank, which has the global tracks (death, game over, invincibility, etc.), and then load in an different block of data with level music on it.

No, man... use the theme from Zelda when you warp between dark/light world.

---

The only thing is--I want this to primarily be a SMB2 music patch. I don't want to get rid of any of the SMB2 tracks, but I do want to replace all of the repeated tracks in the pointer table. Possibly, if I made a Zelda hack(doesn't necessarily mean I will) I'd put that as the keyhole exit.

OK, so those low/middle/high bytes are the pointers to the music banks? Then you'd just have to change the routine at 730D6 to use a table indexed by level number. (Nevermind the overworld, I forgot that music banks can hold more than one song, durrr. )

---

Those addresses aren't the locations of routines, but the starting addresses of the actual SPC data blocks.
From what I can see, a subroutine that starts at 2E8 loads the SPC engine from 70200, then it jumps to a subroutine at 279. Another subroutine at 2FD loads the sample pointers from 78200, and so on. All of the subroutines are in that general area.
