Ok, so I bought the "wrong one" Wink Anyway to easily disable the mod? I feel reeeaally stupid now Sad

Don't disable the mod, as it allows you to run more things. As it is, you can run a lot of good games, including:

- Xevious
- All 32 Compile DiscStations
- Golvellius 2
- Gorby's Pipeline
- Rune Master 1
- Rune Master 2
- Bomber Man
- Pumpkin Adventure II
- Pumpkin Adventure III
- Pentaro Odyssey

And very nice demos, like:
- Unknown Reality
- Raytrace Demo

And why would you disable the mod!??

Also, almost all Dutch MSX software (demos, games) after 1992 or so supports MSX-Audio.

Bas just sent me this info:

"With esc you start the program (Toshiba)
With _audio you can use the sound in basic
with tab you disconnect the audio basic. (some programs need that), but you can listen the music by audio (some compile games)"

Hey, BAS! Which games don't run with the MSX-Audio BIOS enabled? I would like to have a look at that.

I really don't get this. Bas told me that a combination of msx-music AND msx-audio is great. Ok, made some tests: msx-audio games are ok, but (apparently as it should be) msx-music games don't give any sound from the module (only the internal psg if both of them are supported). The number of msx2 games with (only) msx-music is about 180. The number of games with msx-audio is only something like 25. That's why I was wondering about disabling the mod. If you ask me, I prefer an extension with better support in games. I don't need/want demo etc compatibility. People keep telling me that I'm better off with this modded version than the original, but if I "loose sound" for almost 200 games, I think it's not a good thing.

Sorry about this b*tching here Sad

olliraa: I think you are still confused Tongue

MSX-Audio and MSX-Music are totally different things. You won't get any support for MSX-Music even if you remove the mod from your MSX-Audio module. In theory, you could modify the existing software made for MSX-Music to work with MSX-Audio, but no one has done so. You could have used the poke mentioned above, but if I understand correctly, since you have the MOD, the poke command is not needed since the BIOS installed in your mod makes the games and disk magazines that benefit from the poke, already recognize the MSX-Audio (I might be wrong with some details, I don't own any MSX-Audio, jsut two MSX-Music modules LOL! )

So by removing the mod you won't gain anything Big smile. In fact, if I'm reading this documentation correctly, you can disable the MOD by holding TAB while booting. But this is for extremely rare cases where (in theory) something might conflict with the MSX-AUDIO BIOS in the mod.

MSX Audio is made by Toshiba, Philips and Panasonic. All three have different specs, but all have an OPL1 compatible FM synthesizer on board with 9 channels.
For the Philips and Toshiba versions the cartridge was mainly developed for the built in software in combination with a musical keyboard.
The Toshiba version was the most stripped version of the three versions since it didn't come with any sample RAM.
Philips released its music module with 32kB sampleram.
In the mid 90s some scene guys upgraded this to 256kB sampleram.
The Panasonic version had some bios thing which I'm not familiar with, but at least the cartridge is supported by some compile software thanks to this bios.

Now, to give the quite stripped Toshiba a big boost in the right direction some scene guys (forgot who, sorry) made a little mod which puts the best of all three versions in one cartridge.

So, it's still a music cartridge with only MSX Audio compatibility.

MSX Music was released in cartridge form by Panasonic as FM-PAC, just before MSX2+ got released. Since Panasonic integrated MSX Music in their MSX2+ (and later MSX turbo R) computers, the FM-PAC cartridge got obsolete and therefor Panasonic discontinued the production of the MSX Music cartridge called FM-PAC.
Because of that a lot of hobbyists started making clones. Therefor it's needless to name a list of all the versions.
MSX Music has a different music chip on board than the MSX Audio, namely the OPLL. It has 6 channels of FM when drums are being used and 9 channels of FM when drums are not being used.

MSX Music was quite popular in Japan. Therefor most companies used it. MSX Audio has always been a bit rare. MSX Audio is not supported by Japanese games (just the few titles mentioned by the other guys do).

So, MSX Music and MSX Audio are two physical totally different standards. No matter what one solders on your Toshiba, Philips or Panasonic MSX Audio, it will always be an MSX Audio.
Same thing as if you put more ram, more speed, an extra diskdrive and what not in your Sony MSX, it will always be a Sony MSX and not a Philips.

If you were expecting to play all those Japanese gems, you got quite fnooked indeed, cuz it won't work and never will.

But you didn't buy crap either.

Like the other guys said, loads of software from the mid 90s up to now do support MSX Audio. Just because some sceners from that era found that MSX Audio was worth its attention and use.

Ehr... That's all...

Ok, I'm going slightly mad Big smile Big smile Big smile I just realized the whole thing: Somehow I had the impression that the HX-MU900 actually was a msx-music module... And with this mod it would also get the msx-audio capability. As the Toshiba is an msx-audio module, the whole thing and your friendly advice makes sense. Goddamn I've been a real moron here. *apologizes all the suffering msx lovers* ;D

I rest my case Smile

The mix up might be because of the name Philips gave to its MSX Audio cartridge: Music Module (not sure what name Toshiba gave its cartridge).
Music Module is the name of the product, not the name of the musical standard.

FM-PAC => MSX Music
Music Module => MSX Audio

Clear explanation.
But what about the signs/symbols used for it?
