If you know them right off the top of your head, please share them if you wouldn't mind! I'd love to add them to the pack-fixing thread.

I'm having a bit of fun with these softwares so this is what I've found.

Gens K Mod Values:

Mr. Nutz Hoppin' Mad (Europe) (Proto)

Z80

01B0 - 0408

01B0 - 4DB00080 80009F00 "3rd and 4th digits rapid flick on the first line"
0408 - 00808000 00000000 "4th digit on 2nd line rapid flickers.

68k

F000 - FFB8

F000 - 00000000 0000FFFF "Flickers rapidly on the 4th digit and does some climbing like rapids on the last 2 digits of the 1st line, final 4 digits are rapid flicker on the second line"
FFB8 - 000CE866 000CE2BE "Final 2 digits on the first line are the rapid flicker, with a picture of a poo flashing which is a funny symbol for an end of the track"

Hope that helps you guys out hacking this one.

Sorry for the incredibly late reply but I have been [insert lame excuse here because I can't think of any as of typing]. Here are my latest codes to allow easier ripping and or listening to music playback. I do plan on adding the additional songs to the sets. The additional codes will stop the CPU from doing anythig except for parsing only audio related I/O in most cases they are were written in mind to play the music and or sounds and samples at the earliest most convent instances possible in the games.

I actually forgot about this version when I did Comix Zone. Also, found some interesting stuff. Several music tracks were removed most likely because this was a near final build and they needed ROM space. Still, interesting to hear some songs that didn't make it into the final version. Wonder how many songs Howard Drossin composed in total. Songs 1C, 1D aren't listed in the song table and they're duplicates. I don't hear any differences from the final song but I only listened once.

Thanks! I have more coming. I would love to spend hours logging VGM sets but there's literally no time or patience.

It's possible hacking music from EA games like Blockout, John Madden, and Streets of Rage series??

The soundtracks for these games can be found in the Downloads tab up top, by clicking the letter corresponding to the name of the game.

The soundtracks should be complete, if not, moderately up-to-date (as I have no newer versions in my packs to work on), so is there anything in specific you're trying to accomplish?

Would appreciate if someone looked into Mario Lemieux Hockey. That game has no known access to a sound test and songs either last too short or get drowned by the "crowd" during a hockey match.

Hacking for VGMs

Postby ValleyBell » Sat Apr 11, 2020 3:58 am

I did some research and have hacking info for a few games.
There are short instructions at the bottom of each code block that help you to make a sound test ROM.
The format is: [offset] [bytes in the original rom] -> [bytes after replacement] [comment describing what effect this patch has]

Ultraman
Code: Select all
sound driver calls:
038000 - Sound Driver Update [no parameters]
038004 - Stop All Sound [no parameters]
038008 - Play PCM SFX [register D0 = SFX ID]
03800C - Play Sound [register D0 = sound ID, register D1 = number of channels]
038010 - ?? (unused?)
038014 - ?? (unused?)
038018 - Fade Out [register D0 = fade speed?]
03801C - Load Z80 Driver [no parameters]
038020 - ?? [register D0 = some ID]
038024 - ?? [register D0 = some ID]

General Music List:   007172 (2 bytes for entry, list contains 14h entries = 28h bytes total)
    for each entry: 1 byte - ID [reg D0], 1 byte - channel count [reg D1]
Level BGM List:      007178 (part of the General Music List)

The sound driver has a huge pointer list 039D88. These are pointers to "track headers".
In order to load a song, it specifies the ID of the first track header (register D0) and the number of channels/track headers (register D1) to be loaded.
Then it calls "PlaySound".
So if it loads "reg D0 = 45h, reg D1 = 3", it loads the track headers for with IDs 45h, 46h and 47h.
The list contains SFX as well as songs and the game code has the "first track ID" and "channel count" values hardcoded.

playing the "Stage Select" music is done using the following code:
006C7C   70 4F      MOVEQ   #$4F, D0   ; reg D0: sound ID
006C7E   72 06      MOVEQ   #$06, D1   ; reg D1: channel count
006C80   4EB9 0003 800C   JSR   $03800C      ; call PlaySound

a search pattern for "Play Sound" routine:
70## 72## 4EB9 0003 800C


You can make a simple "sound test" patch by modifying the ROM this way:
000328   4E71 -> 6048      skip checksum check
000430   4EB9 0000 -> 4EF8 21C0   skip to "stage 1" screen [we use it for playing songs]
006C7C   704F -> 70xx      set xx = sound ID
006C7E   7206 -> 72xx      set xx = channel count


Mario Lemieux Hockey
Code: Select all
FF9458   offset to Track RAM for current song
   Note: Each song has its own (!) track RAM.
FFD406   decompressed song data

sound calls:
022086   Sound Driver Update
022452   play title music
022512   stop music
022536   play menu music
022548   play ??
0225F2   play fight music
022604   play ??
022698   play shoot out music
0226F8   play ??

I have to mention that the sound system in this game is a total mess.
Each song is in a separate "sound bank" and each sound bank has its own work RAM.
The pointer stored at FF9458 in 68k RAM tells the sound driver, which part of the sound bank RAM it has to update.
This also has the interesting effect, that the menu SFX stop working when you play e.g. the title theme on the menu screen.
In order to play a song, the game calls one of the "play XX" routines, which has all *hardcoded* offsets for track RAM and song data.


sound test patch:
000498   4EB9 -> 601A            skip title screen
0004CE   4EB9 0002 2452 -> 4EB9 0002 2512   don't play music at SEGA screen
000556   6600 -> 6000            cut SEGA logo short
0009A8   4EB9 0002 2536 -> 4EB9 00xx xxxx   insert address of "play XX" routine at xx

Nice!

Thanks for sharing, ValleyBell.

Who's in charge of keeping the Wiki updated? It would be nice to have this information neatly gathered and ordered in the Wiki.

Also, I've been in talks with the blast'em emulator dev to implement a new VGM logger on his cycle accurate emulator.
I want to put KEGA's logger to the test to see if it has been doing its work properly by pitting it against a known accurate emulator.

Monkeymook has also created a Discord server for Project2612, we'd be delighted to have you on board.
