A small VGM Music, for Super Basketball (the game is a demo), but in YM2413 mode. The PAR code was I have used is there: 00D000:01. For some reason, some emulators, such as Kega Fusion and FrezzeSMS don't work. But work on Meka and in MESS!

Another games that have FM sound, but the game not activate:

* Assault City (only two musics work)
* Battle Out Run
* Double Hawk
* Dynamite Dux*
* Rambo III*
* Summer Games* (only Prototype, but the patch in ROM is ROM[00A3] = C3, 03, 80)
* Super Basketball*

Games what * appears, it means that it does not work in some emulators (ie: Kega Fusion, FrezzeSMS).

Have Fun!

That's very interesting! Where did you found about those games? Do they all functions with the same patch (writing 01 at D000) ?

I have used Memory Editor on Meka 0.73 WIP (on time of these RIP), and i have triggered on D003 with the value 81. Another values, are null sounds, and some values, cause the game on crash!

And the PAR codes in other games:

* Battle Out Run: 00DE00:01
* Double Hawk: 00DD00:01
* Dynamite Dux: 00D000:01
* Rambo III: 00DE80:01
* Summer Games (Proto and Original): 00C001:01

In Dynamite Dux, the value returns a 00 (SN76489) with you complete a Round, Reset or starting a game.

In Rambo III, I have found a Patch on ROM, but have a minor graphic issues on the Title Screen: ROM[00AC] = ?? (any value, except 00. On my patch, is 80).

In Super Basketball, the Patch on ROM is ROM[009D] = 01 (Sega Logo is Corrupt, but only for the first time).

There a lot of games with have a sound FM, but the sounds are incomplete. These games was not released in Japan (except Ys):

* Aerial Assault
* Assault City (two musics are fully sounds)
* Basketball Nightmare
* Dead Angle (crash)
* Forgotten Worlds
* Psycho Fox
* Reggie Jackson Baseball (with a pitcher thworing a ball or the ball down on the stadium, crash)
* Walter Payton Football (crash)
* World Games (Prototype and Original)
* Ys (american version) (crash)

Battle Out Run doesn't sound quite right, but Rambo III sounds great.

You can also enable the FM in Wanted, but it messes up the game.

Very cool stuff, thanks for posting this! I was able to use a hex editor to patch Rambo III and Super Basketball, and they worked just fine in SMS Plus. The patch to the Summer Games prototype didn't work, but then I loaded the unpatched original...and it sounds like FM sound is already enabled? Or am I hallucinating?

Is there any way to hard patch the other games? SMS Plus can't use PAR codes, and I'm still on a PPC Mac so my options for other emulators are limited. Maybe some intrepid hacker can figure out a way to patch the FM soundtracks into these games without crashes or graphical glitches? I'm curious why that one byte causes a title screen glitch in Rambo III...

You have to find out whether the Streets of Rage II has a code Hidden FM ?

Are there any prepatched roms for this? Because I don't really understand how to apply the patch.

Hello folks!

As I wanted to hear these on my Japanese Master System - and because people had voiced interest in having access to patched files - I thought I'd create the required ips as a sort of mini 'teach yourself z80 programming' project.

I've attached a pack containing patches, ROM patching software (emulicious) and a readme that will run you through the (very simple) patching process.

just for fun, here are the incomplete soundtracks too :D

I'd like to unbundle these and add them to our hacks listing, if you don't mind.

I wouldn't have known where to begin if it wasn't for you guys so I'd consider it an honour!

Hello fatnick, I'll try these games in FM are amazing ;)

I did a simple hack example using PAUSE button switching PSG/FM sound, if you like idea you can redo hacks

- Default is PSG sound
- "INgame" PAUSE only PAUSE Game, elsewhere switch PSG/FM

Rambo III FM-Pause Hack.ips (43 B)

Oh thanks for that. Personally I'm not really a fan of switching between the two - I tried playing around with values but i couldn't find a way to do it without mucking up the sound for a little bit.

Thank you for sharing the code though - as i wasn't 100% on how to do it anyway. I especially like the way you've kept the pause code in place :)

I did it first (?) for the Phantasy Star retranslation. Due to the way the engines work, you have to retry the music to switch chip, but a clean "stop music, change settings, start music" should generally work as it reinitializes everything.

For these patches, it would be nice to share source. I always use WLA DX to patch and overlay because writing assembly in hex is hard.

I'll give that a look!

The first lot i mostly did at home with your proscribed Context/WLA DX combo. As i was at work for the second lot - a i didn't have access to a PC - i used emulicious to look at the code and hexfiend to edit the hex directly (flash harry!)
