Homebrew [Release] PicoDrive for 3DS

[huntertron1]

this is realy good but i noticed that it runs at pal speeds sadly so bacicly my roms im used to running at 60 fps runs at 49.9 fps on the dot but its playable and works on rpghax (yes i managed to get that before nintendo patched it it works on 11.6) so ill give it a 9/10

Next version will make the default FPS for World ROMs be 60.

Oh also, it seems like the version of Picodrive 3DS on the TitleDB for FBI is still 0.91 instead of the latest 0.92

I imagine the next emulator port will be Yabause (Saturn emulator), but it's dynarec code needs to be reworked for 3DS, since it's slow on RetroArch 3DS.

I would be the odd ball here, but seeing bubble2k's incredible coding abilities, I would like to suggest a port of a Virtual Boy emulator for the 3DS with proper 3D.

It's like a match made in heaven, Virtual Boy emu in a 3DS, which has sadly not seen the light of day yet.

1. 0.92 isn't the latest because the one released on gbatemp is just a beta. He said that he will update it soon.

2. Retroarch has a pretty decent Virtualboy emulator. I just don't use it because it hurts my eyes.

Ya know, I'd love to see him at least try something regarding N64 or PS1, at least for new 3DS. Everyone says N64 is impossible, but given how well his are done, I wouldn't be surprised if it did decently. And PS1 runs okay on RetroArch, surprisingly enough, so a dedicated port ought to work well.

PS1 is a lot less advanced than the N64 in terms of hardware. And N64 is so notoriously hard to emulate that we still don't have a perfect emulator on computers.
And considering that I can't get SM64 working well on a computer with 4 GB of RAM and a 1 GHz processor, the N3DS has no chance in hell.

And every single time someone says this, someone says "u fcking liar the psp can emelate n64 good"
This is because the PSP and N64 share the same processor, which means there's less hardware that need to be emulated, with the processor being one of the most difficult things to emulate.

Yup. Cos there's a very nasty crashing bug in v0.92beta when opening Mega CD games that I've only just fixed. In some 3DSes you may experience getting booted out to the Home menu, in other versions, it will crash with an ARM11 exception.

So I will probably release an official 0.92 in a couple of days after more testing.

I won't want to kill myself rewriting major parts of the emulator... and not even getting it close to 60FPS. So N64 is probably out. I'd rather work on something that is likely to push to 60 FPS with just some work and there.

Isn't there one already written? My take is that the library of games are too small to invest so much time in it.

PSP is easy to emulate even on android though

The PSP is less advanced I think. N64 has some ridiculous chips in it that are notoriously hard to emulate.
There's also stuff that can't be emulated or something that causes differences between playing on N64 and emulators.
The most known thing is probably the difference in how Morpha looks on N64 and emulators.

To be honest, PSP nor Android can give a smooth N64 gaming experience, even in 2018 the best way to play the entire N64 library is an Everdrive + a Gamecube adaptor on a retail N64.

There is one which was a PoC/WIP called r3Ddragon.
https://github.com/mrdanielps/r3Ddragon

Though that one hasn't been touched in years I think, and no commercial ROM works at playable speeds.
It might be of some help or base to work on, but I don't know a thing about this nor technical stuff on emulators.

What i believe is that any non-3D console would work at a decent speed on a 3DS, since it would require less processing power, and to be honest I doubt anything from Saturn and onwards could work at good speeds on the 3DS.

In short, Virtual Boy in 3D without the obnoxious huge red visor is a dream I'd love to see.

Oh and thanks for the explanation on the beta, I will look forward for the official version in the TitleDB.
And no wonder I didnt bump into the CD issue, I have no Sega CD games in my library lol

on wiirtualboy there where filters that made it different colors, and even blue and red for 3d glasses

Not impossible but you would need a very good dynarec core and it would almost certainly have to be a HLE emulator like UltraHLE/Corn/etc which means limited game compatibility and no possibility of Rareware games.

My suggestion would be either a Gambatte port or getting mGBA working full speed on the o3ds. Also, I am not sure if you already know but someone made a simple library that will check if the dsp firmware file is present and automatically dump it (from the home menu .code section) if it is not.

Working on GameYob is a good option too.
It's mostly working, it just needs some tweaks from the DS version to work just fine, although I'd go for mGBA mostly, since that already works amazingly with almos all GB/GBC titles, and just needs some ARM specific code to get the most heavy games like Golden Sun 2 working 60 fps.
GS2 works at like 50-55 right now, dropping mostly to 45.
All other games work between 55-60 with zero to no issues.

But yeah, Gameyob, mGBA or r3ddragon would be my suggestions

these emulators are for old 3ds though i don't think mgba runs close to 60 fps on old 3ds.

 

[JohnSheridan]

I would love to have a good MSX Emulator on 3DS. I think it should be possible on O3DS. And the MSX have hundreds, even thousands, of fantastic games!

A Game Gear Emulator would be fantastic too.

Tested Final Fight CD with the latest r150 bulid on my new3ds. I can hear occasional noise on background music, and a continuous "pop" sound when stage 1 start. The noise and "pop" sound are not obvious, but they don't exist when using Retroarch Picodrive Core. If you use earphone and compare the music of these two emulators, I am sure you will notice the difference.
