Homebrew [Release] PicoDrive for 3DS

[wicksand420]

This is the first time I try the mega CD, I'm stuck on the audio player ...

if you are in the bios and you press c on sega, which is A on 3ds, it will go to the audio player, if this happens just go to "CD-ROM" and press Y to start

Where is CD-ROM?

You're out of luck. Try 0.91b (3DSX only), which should be a few pages back, or wait for the next version.

I can't bring myself to play SMS in picodrive without FM Synth on the games that supported it (basically most of my SMS games), I know the retroarch version lacked it but is there any possibility at all to add it in this version? (Don't know why I can't but it's probably because I got so used to it in genplusgx on the wii)

Ooh I didn't know about the FM Sound Unit, but the sound is so much better, it's a night and day difference! An option to activate this would be awesome!

 

[Krem Quay]

AVGN much =]

lol yeah, I remember watching that episode years back. One of his best episodes he's done, in my opinion. I like how it was two-parter.

If your ISOs are like 128MB or lower, they won't work, but he will look into that issue.

Oh Robz, can you help to describe what happens when a small ISO is loaded? Does the emulator crash? Or it goes into the CD player?

Not sure about the FM sound unit. For me, I can't just turn it on since the code was never there. If I've to add that, it'll probably take a while to explore what this FM sound unit does, and how the games communicate with it. Is it true that it only supports specific games? Or all SMS games can play through the FM sound mod.

It goes into the CD player.
Also, it takes a few seconds before the "Press START" message shows in the Sega CD logo screen.

If the small iso is converted to bin does it still do that? Could you give some examples of small games? maybe i have one i could test.

The only ones I've tested are SonicCD++ and Sonic Megamix 5.0b.
If the .iso is renamed to .bin, I think it should have the same effect, but I haven't tested that.
Any small game should be any ISOs with CDDA tracks separate from it.

Can you just rename iso to bin like that?

Yeah. Data should be the same.

the ones i have contain the music files inside the bin

Sonic CD ++ works when converted to bin, to do so, make sure your cue is correct, burn it to cd, then use imgburn to make a bin image

Nah, here's a list: https://segaretro.org/FM_Sound_Unit
You can listen to the difference, there are numerous YouTube comparison videos around. Thanks for checking this out!

Wow, that thing was crazy expensive.

Snatcher works perfectly now.
Thank you, lovely human being.

Mine is the BIN/CUE version. Is your ISO version the one with the WAV files? I can't find such dumps online.

Thank you very much for the update.

I tested r159 build with my new3ds. The music of Final Fight CD sounds OK now. I also tested some MD roms, and found some bugs.

1. Streets of Rage (W) (REV 00) [!]: The background music sounds not right. I can hear a very quick "pop" sound. The music of Retroarch Genesis Plus GX and Picodrive cores sound good. There is also a graphical glitch. A line is missing above the HP gauge. This glitch also exists when using Retroarch Picodrive core, but in Genesis Plus GX core the graphic is normal. Maybe it is core problem.

2. Streets of Rage 2 (JE) [!]: The game runs in 50 fps and is obvious slow. Other Japanese version roms I tested run correctly in 60fps.

3. For all MD roms I tested, I feel the music of your emulator is somewhat different compared with Retroarch Genesis Plus GX and Picodrive cores. The music of Retroarch is more pleasing to my ears, while it is a little weird in your emulator.

4. Super Street Fighter II - The New Challengers (U) [c][!]: The graphic of some stage grounds are broken, which are normal using Retroarch Genesis Plus GX and Picodrive cores.

5. Can you please map 3DS L X R buttons to MD X Y Z buttons by default?

Finally can you please release a quick update for Temperpce adding a toggle for 2 and 6 buttons? This emulator seems excellent, except I can't play SF2 CE properly on the default 2 buttons layout.

Thanks again for all your effort for bringing these amazing emulators to us!

I noticed the graphic problem with SF2. Not sure why... I'll see if anything can be done with that.

As for music, do you happen to be using an Old 3DS? If so, that might explain the difference. The music is generated at a lower sampling rate which gives a noisier feel, and the high frequency tones won't sound as good. Because I wanted to offload the FM music to the 2nd core to keep things running at 60 FPS, the FM music takes a hit in quality. Unfortunately, but nothing much I can do. The Ne

iirc FM Synth on the SMS side of things make a check of sorts to determine whether to use the SN76489 (PSG) or YM2413 (FM Synth) depending on whether or not the expansion board is detected (I'm probably way off but that's my limited understanding) to be honest I don't have an entire understanding on the subject
