Genesis Plus GX

Some more information here from eke about how the MD+ addition works and is detected: https://github.com/ekeeke/Genesis-Plus-GX/issues/297#issuecomment-918468508

It doesn't appear as though the header edit is necessary. It's the MD+ specific commands detected in the CUE file that are read, as long as the ROM and CUE file are the same name. In saying that, though, I did test out Super SF2 without the header edit and the opening theme started again when it shouldn't and the audio volume was definitely lower when I started a game, compared to how loud/normal it sounded during the intro. Then again that should probably have the SSF2 header, maybe.

Ah, yes, I mis-read that.

It was this that caught my eye first

although no known games are using them, MegaSD extended SSF2 mapper and limited ROM write mapper (automatically enabled when respectively "SEGA SSF2" and "SEGA MEGASD" are found in loaded ROM header) are also emulated, according to the description in MegaSD dev manual . Note that MegaSD overlay will also automatically be enabled when these mappers are detected, no matter of the "CD Add-on" option.

That being said, it really works a treat with this new core update.
Once again, if Eke-Eke should happen to read this, thank you so much for adding support.

Definitely noticing some little bugs with the audio. The volume levels fluctuate, and doesn't seem to be quite at the same level of a MegaSD on real hardware. A little louder than my setup, anyway.

Street Fighter II' Special Champion Edition character select screen, when selecting a character the volume fades out.

Link in OP updated with latest version.

fixed MegaSD edge case occurring when 'play' command is sent while previous track fade out is still in progress

Nice. It's getting there. Thanks for the build.

There's an issue with loops. Some tracks that are specified to loop, don't loop and vice versa. If a track does loop, the loops are not at all accurate. Again, using SFII' SCE as my test.

And there's the minor issue with volume still. The MegaSD has its default CDDA volume set at 80% and that's what I would use to balance the sound packs. It sounds like the G+GX setting is at 100%. Not at all eke's fault, he probably doesn't know. Maybe a CDDA volume slider like the MegaSD would be useful, or an overall 20% reduction in CDDA volume for that particular portion of the core.

Hello.

Did you wrote an issue about this in his github?

Yes, something still isn't quite right.

In Darius II/Sagaia, the jingle when you enter options screen keeps looping until you press start and enter level 1.

It behaves correctly when played in MD+ MAME.

I have now, as I'm not sure he's monitoring this thread. Although the fade fix suggests he might be, or maybe Retroplay informed him. Anyway...

Yes, latest commit certainly improved things.

Hello.
There is a Problem with newes "Genesis Plus GX 1.7.4 2ef6f58" Core and playing MD+ Games. Its still playing only the first .wav Audio. If the Game goes to Level 2 its nothing playing. If i press pause and start the Game continues with the first Music .wav file. And this appears in all MD+ Games. Only the first .wav file is playing. Is this a known issue?

No such problems here with that exact version of G+GX.

I haven't encountered any problems in any of the available MD+ patched games.
That said, I do edit header at 0x100 to "SEGA MEGASD" in all the MD+ games I play in GX.

Try the Eke-Eke core, it's 236e783, link in first post, it's the only one I use.
Maybe libretro branch (from RA core updater) haven't caught up with Eke-Eke's recent MD+ fixes.

It caught up pretty quickly after the final fixes. About a week or so after that.

O.k. i found out that .ogg files working. I edited the .cue from wav to ogg and converted the .wav to .ogg!  Now its working fine with all Levels and Menue music. I like that, because its smaller than .wav for use on micro-sd cards.

Hi guys, how are you?
I have some mp3 files that I wanna use to update the Super Street Fighter 2 to sounds like Ultra Street Fighter 2 from Nintendo Switch, but everytime I convert the mp3 files to WAV, and put it into the right folder, the music plays slowly in-game. What could I do to make it work right? The mp3 files are at 48000 Hz. Tried the same with SNES msu-1, but the result was the same...  

You need to convert them to 44100 Hz.

Thanks work great on windows xp 32 bits, can you compile fuse core?. Thanks
