Request for MD+ sound patches.
« on: May 07, 2021, 02:11 AM »
Hello, I would like to know if there are plans to support MD + sound rom hacks, since I have been looking for MSU patches but there are really very few, most of them are made for MD +. The only person who is working on MSU patches is Mr. ArcadeTV and the vast majority are in MD + format. It is frustrating not being able to use all those patches.

The opposite would be true as the vast majority of patches available are MSU-MD, but most of them are pretty much untested and in a pre-release state. You can get them at ArcadeTV's GitHub.

Krikzz has stated before he's not interested in implementing MD+ for his cart, which is a shame really. It's an open standard and clearly the better of the two where having an Everdrive Pro or a  MegaSD is concerned. Seamless looping of audio is important as MSU1 set the standard and results in a 50% reduction in audio file sizes most of the time, also the code needed for patching is miniscule compared to MSU-MD and can be an important factor where ROM space is concerned (e.g. Xeno Crisis).

MSU-MD has its place, but really only for people who don't have a Pro. Using anything other than MD+ for an ODE capable flash cart such as the Pro and the MegaSD makes no sense.

Is sad that Krikzz do not wanto make support for MD+, but the MegaSD developers says tha if MSU becomes mor popular, they would be willing to support the MSU format.
I see the site of Arcade TV and even help me to do the target heart, Langrisser 1 and 2 patches, I help with the OST for them, but it seems to me that it is a lot of work just for him, I don't see that someone else is doing patches with MSU support.

MD+ format not compatible with Real Sega / Mega CD system

Real Sega / Mega CD system already supports MSU-MD since 1991

Emulator like Kega Fusion already supports MSU-MD since 2005

commercial sold game like Pier Solar already uses MSU-MD since 2015

technically MegaSD should already supports MSU-MD, if MegaSD support Sega CD Mode 1

Just google "Sega CD Mode 1" for more information about MSU-MD

I don't know where you got that from, but the MegaSD already supports MSU-MD and always has.

Ho I see, apparently I made a bad purchase, I must have bought a Mega SD then from what you tell me it has much better characteristics. A pity that  do not want to implement the 2 formats in the megaever drive pro.

I think that the more features a product has, the more attractive it becomes to its users.

Well my request was that since there are MD + games that do not have their equivalent in the MSU format

Anyway, thank you very much for your comment, there were many things that I did not know. I should have found out before making the purchase.

Is there some way to make an expansion cartridge or something that allows using MD+ on a real Mega CD?
If not, I would have to say that I agree with Krikzz that MD+ is controversial. It's not like the MSU-1 for the SD2SNES which is just a co-processor in the cartridge. That's the natural way to expand the SNES. The MD+ on the other hand seems to be an unofficial expansion of the hardware that has no counterpart in the real hardware and can not be expanded in real hardware in a natural way.

There's nothing "controversial" about it. Krikzz simply didn't implement it because it was developed by a competitor.

But it still requires an alternative to the real Mega CD right? There is no way to get it to work with burned or pressed discs?

Yes and no in that order, but I don't understand your point in the overall scheme of things. Why would you want to attach a CD unit and use burned CD's when you have an ODE capable flash cart such as the Pro or a MegaSD? That's just silly and completely redundant. MSU-MD and a CD unit makes sense for people with an X3, 5, 7 or whatever as their carts aren't capable of emulating CD hardware. MD+ is a better alternative for Pro and MegaSD users and works in exactly the same way MSU1 does on an SD2SNES.

big differences between MSU-MD and MD+

MSU-MD requires all games patch with cd driver address

MD+ requires all games header changed, to trigger MegaSD ODE CD in firmware

both reqiure asm coding to redirect audio to CD tracks

MD+ doesn't require that on MegaSD, but MSU-MD and Mode 1 hacks do need their headers changed for them to be detected. The next MegaSD firmware won't require that change.

It's an expansion of the hardware that requires a very specific setup to play the games.

I've realized that I shouldn't have said controversial. In the end it's just an unofficial expansion of the hardware, not something that causes any kind of damage.
