Homebrew Retroarch Emulation Thread (Nightly Builds Included)

[mightymuffy]

Dunno if it's okay to ask this, but is there any chance you could add Virtual Jaguar in a future update if it's possible (I don't see how it wouldn't be able to run at a playable speed on the n3ds)? http://wiki.libretro.com/index.php?title=Virtual_Jaguar
I'd love to play Jag games on the go!

Despite not being anywhere near a PS1 in terms of raw power, the funky architecture of the Jag means it'll likely run slower than pcsx does. In fact there's never been a PC emulator that runs Jag games with around 100% compatibility!
Standalone Virtual Jaguar (I think) was ported over to the [more powerful] Wii, didn't have sound, and ran mostly at around 50% speed: after seeing how good ps1 runs on 3DS I'm the first un to say 'never say never' - but don't get your hopes up unfortunately...

FF7 ran at a decent speed on the psx emulator as a Cia right? I recently set my n3ds up with cfw and am wondering what I do to benefit from it. Just install psx rearmed as a cia? Or is there more to it?

I have the audio muted and installed as a cia on my n3ds and I just tested it out quickly and its running at 59 fps I did the first segment and battle with the guards.

And not sure how far fetch is to ask but how come the n64 isn't out for the 3ds version?

anyone wanna share their GPSP settings for .cia new 3ds users? I almost got full speed on all games I tested but the upper part of the screen is flickering and this is really annoying and I dont know which settings I have to change . thx

You could try switching Bilinear Filter On and that might help, but I found out that it doesn't help for all the games.
The tearing issue is mostly a unknown problem by now, since the developers haven't been able to reproduce it.

You can use the following build, it seems to be working fine:

Aww man... Didn't even notice it was deleted. Let me see if by any chance I still have them.

EDIT: Here it is!

My guess is because of just how hard N64 emulation is, due to its hardware. Regardless, I'm eagerly awaiting a possible future release. It would be a dream come true to have Mario 64 and F-Zero X on my N3DS. Though obviously it'd be quite a challenge since it'd need to be optimized wonderfully, after all the PS1 has a weaker processor and even that is pushing the N3DS' limits it seems. But we can be hopeful, the PSP had a barely functioning N64 emulator, and the N3DS is quite a bit more powerful than that old thing.

thx this version works great without the tearing

Good.
What about compatibility?

I'm no tech expert, just a random guy wanting to play old games on new hardware. I was wondering, though, if there was some way to let Retroarch skip frames.
On CATSFC (New 3DS, Ironhax, .3dsx), Final Fantasy 6 runs at constant 59 fps most of the time, except in some areas, where it drops to 41-42 fps. I noticed, though, that when the framerate drops the game slows down.
Now correct me if I'm wrong, but It seems to me that most games run at 30 fps on consoles. So how is it possible that the game slows down at 40?
I wanted to try and change the "Refresh Rate" value in Settings--->Video from 59.834 Hz to 30.000 Hz, but getting to 58 takes forever.

I actually think that a lot of games for the SNES runs at 60fps. So of course if the framerate drops below 60fps the game will slow down. Lowering the screen refresh rate won't help in this case. If you set the screen refresh rate to 30Hz on a game that supposed to run at 60fps then the game will run at half speed. However if a game was running too FAST then this method would probably work. But like you said, adjusting the screen refresh rate takes forever. There really needs to be a frame rate limiter in the settings menu to adjust the maximum framerate quickly. I don't know how hard it would be to implement something like this but I would love to see it in future updates.

Are .cht files confirmed working for Gambatte? Any of the pokemon games?

I didn't know the ps1 has a weaker processor. I would say for the N3DS the ps1 is pushing it, with muted audio I just manage to get 59 fps in and out of battles of FF7 from what I tested in the beginning anyway. I as well would love to be playing Banjo right on my N3DS. I'm hoping as well brother, fingers crossed

I want to try this out also, someone said a couple pages back there is a file you edit and you can set it to whatever you want

I tried this with the "retroarch.cfg" file in root\retroarch, but it doesn't work. It does let you save the changes, but, as soon as you run retroarch, the value goes back to the default one (59).

 

[ShadowOne333]

Any reason why the changes I make to the Input per core is not being saved?
I have tried exiting retroarch normally, saving the .cfg after the changes and even saving a new .cfg, but everytime I boot any core, it defaults to the previous, original button layout.

Will there be a day when O3DS will get full speed GBA emulation?

Sure, AGB_FIRM.

Joking aside, since it isn't an emulator at all, I wouldn't count on it. O3DS is just really, really weak.

Alright, anyways I'm thinking of trying AGB_FIRM and is there a chance of bricking? Is there a good tutorial?

Yeah, the N64's processor was around 3 times faster (93MHz vs 33MHz). Processor speed alone isn't a good way at all to judge the power of older consoles though since so many functions got dedicated hardware, which is why I think the SNES was the most powerful of its generation despite having the weakest processor.

In any case there's definitely hope, after all console gen 5 is around when high-level emulation becomes viable. The big obstacle is just how much of a pain the N64 is to emulate, gotta wait for the Mupen64Plus core to be worked out for 3DS hardware.

You can try setting the config file to read only, but I'm not sure if there are any side effects

 

[Quantumcat]

Can anyone give me some instructions on how to run an exe in DOS using Retroarch?

You won't brick unless you delete the wrong system files.

we never even got a n64 emulator for the ps3
