Here's the updated version of this tool that extracts ROMs from Konami's Game Collection disk images:

Download it here: kgc2roms1.1.zip

It works on MSX-DOS and Win32, and can create both SCC+ and SCC versions of the ROMs.

v1.1 changelog:

Fixed boot-code bug (was causing issues on openMSX).
Support for original 64KB SD Snatcher cartridge.
New SCC detection pattern added (pause in TwinBee now mutes the sound).
Added padding option. 128KB makes all ROMs work fine in openMSX and blueMSX.
Changed the "patching-letters" indicators.

Here's the help file for more details:

KGC2ROMS 1.1
============

coded by Louthrax in January 2015

KGC2ROMS is a tool to extract ROM images from Konami's Game Collection disks.
Created ROMs can be either SCC or SCC+.

Sources are provided under the Creative Commons Attribution-ShareAlike 4.0
International license (<a href="https://creativecommons.org/licenses/by-sa/4.0/" title="https://creativecommons.org/licenses/by-sa/4.0/">https://creativecommons.org/licenses/by-sa/4.0/</a>).

Compared to the existing ROM conversions:

* All 26 ROMs are dumped, in both SCC and SCC+ mode (some games were
previously not available in SCC mode).

* No more random crashes in Knightmare or TwinBee (these crashes were
happening only on non-Turbo machines, it now works on all MSXs).

* Correct set-up of SCC or SCC+ mode at boot time (no more need to specify
it in your ROM loader).

* Unified and more compact loader.

* Support for original 64KB SD Snatcher cartridge. Gradius and Twin Bee
can't be converted in this mode.

MSX-DOS 2 and Win32 versions of the tool are provided (KGC2ROMS.COM and
KGC2ROMS.EXE respectively). Just type KGC2ROMS at the command prompt and
select the SCC mode to start extraction. You can also select a padding for the
SCC ROMs size. 128KB will make your ROMs more compatible with emulators.

You must have the following disk images files in the same directory as
KGC2ROMS:

* KGC1.DSK
CRC32: 113fe20c
TOSEC name: "Konami Game Collection - Volume 1 (1988)(Konami)(Disk 1 of 2)[SCC]"

* KGC2.DSK
CRC32: b5a0f2b3
TOSEC name: "Konami Game Collection - Volume 2 (1988)(Konami)(JP)[SCC]"

* KGC3.DSK
CRC32: 6575f8da
TOSEC name: "Konami Game Collection - Volume 3 (1988)(Konami)(JP)[SCC]"

* KGC4.DSK
CRC32: a3f9a236
TOSEC name: "Konami Game Collection - Volume 4 (1988)(Konami)(JP)[SCC]"

* KGCS.DSK
CRC32: faacf3a6
TOSEC name: "Konami Game Collection Special (1989)(Konami)(JP)[SCC]"

The following ROM files will be created:

kmare.rom.rom Knightmare
aadventu.rom Antarctic Adventure
yieark1.rom Yie Ar Kung-Fu
yieark2.rom Yie Ar Kung-Fu 2

boxing.rom Konami's Boxing
tennis.rom Konami's Tennis (non-SCC)
vhustler.rom Video Hustler
holymp1.rom Hyper Olympic 1 (non-SCC)
hsports2.rom Hyper Sports 2

twinbee.rom Twin Bee
scobra.rom Super Cobra
sjaguar.rom Sky Jaguar
tpilot.rom Time Pilot (non-SCC)
gradius.rom Gradius

soccer.rom Konami's Soccer
pingpong.rom Konami's Ping Pong
golf.rom Konami's Golf (non-SCC)
holymp2.rom Hyper Olympic 2 (non-SCC)
hsports3.rom Hyper Sports 3

pippols.rom Pippols
hrally.rom Hyper Rally
rfighter.rom Road Fighter
tsururin.rom Tsururin Kun
hsomen.rom Hyper Somen
tawase.rom Title Awase
goboard.rom Go Board

Warning: The new ROMs might not be recognized correctly yet in emulators using
CRC checks. You might have to specify the ROM type manually.

The letters displayed during the extraction process are indicating what is
patched. You should get the following output if everything goes well:

Some technical details :

Patching the ROMs to 128KB make them run correctly on both blueMSX and openMSX (result with smaller values may vary, you'll need to add checksums in your emulator database).
The "Patch for 64KB SD Snatcher" generates special ROMs that will only run on 64KB SD Snatcher cartridges. You can launch them with SCROM or ROMLOAD. Thanks to gdx for the idea of this option !
SCC versions will also work on SCC+ cartridges. I'd be cursious to see if there's a game where SCC+ really makes an audible difference.
I have no 128KB expanded SD Snatcher or Snatcher cartridges (well, I have both original ones, but I don't want to damage them !). So I have not been able to test Gradius or Twin Bee on real Konami hardware. Please let me know if someone can do that. I'd be curious to see if the "normal" dump works on a 128KB SD Snatcher ? (if pages 0-7 are filled with added RAM, it should).

You are a chief!

Is it possible to prevent the starting of game by pressing a key at launch?

I found following loaders for the Konami Sound cartridge:
- SCCLOAD by Manuel Pazos (Supports only an SCC+ cartridge extended to 128KB)
- SCROM by Sean Young
- LOADROM by Trunk

I've probably forgotten one.

I'm using ROMLOAD by TNI. If offers a /H option to add an hotkey to disable boot, but I prefer to use the /P:0,0000,00, this just erases the "AB" header and the ROM will never restart. I was surprised by the time needed for the Snatcher and SD Snatcher cartridges to completely erase, you need to wait something like 20 or 30s to be sure that the game does not restart !

ROMLOAD offers lots of options and is really cool, there just seems to be a problem if your SCC cartridge is located in a subslot (MSX freezes and game does not start).

Yes, we need to wait more than 10 seconds for completely erase the Sound cartridge. SC-LOAD (a other loader) has also a option to erase the "AB" code but it is not useful when the game is already running.

I have not yet tried the /H option to add an hotkey to disable boot.

Hi,

I don't get any SCC sound in ROMs converted into SCC+ mode in OpenMSX, if I load them directly (as if they were a cartridge). ROMs I've dumped into SCC mode do work in OpenMSX with SCC sound, however.

It does not matter if I have chosen to load an SCC(-I) extension; I've tried the SCC+, SCC, Snatcher and SD Snatcher sound carts. But if I load them into, say, a virtual MegaFlashRom SCC+, they do work (didn't try others).

Is this intentional / expected? I mean, I just can't pop a SCC+-enabled ROM with the SCC+ in another slot and play? Should I use the plain SCC versions with emulators (as there, probably, is no audible difference)?

Thanks for your work in any case, Louthrax!

It's an intentional limitation in openMSX that does not have direct support for SCC+ roms, contrary to blueMSX.

However, you can use the following workaround :

* Create a DSK file with the following files : MSXDOS.SYS - COMMAND.COM - ROMLOAD.COM - the SCC+ game rom - AUTOEXEC.BAT

* The AUTOEXEC.BAT file needs to contain this command (for the game named as gamesccp) :

romload /5 /s gamesccp.rom

* Insert this disk in drive A and a SCC-I cartridge in a slot before launching the emulated machine in openMSX

Btw, this workaround should be added to the openMSX manual !!!

P.S. In blueMSX, the SCC+ roms can be played directly, you just need to insert manually the rom and select the SCC+ mapper (because the roms generated by Louthrax tool are not in the database).

Thanks mars2000you! Ah, I never though that the SCC+ extensions actually have RAM in them to load games into =). Making a disk image is trivial, but just a little bit more work (also - just because I'm curious, I might do some automated audio dumps with SCC and SCC-I to see if there is or indeed is not any difference, as postulated bu Louthrax above - if I have the time).

mars2000you: it's not a workaround, it's how it works on the real machine...

It can viewed as a workaround because the openMSX developers don't want to add direct SCC+ support. Just like for CAS files : the Nyyrikki script is also a way to bypass the absence of direct support in openMSX for CAS files.
