Emulation What is the current state of PS1 emulation on 3DS?

Alderani · Aug 26, 2024

I just can't find a general consensus online. I see some people saying that the console simply isn't powerful enough to run PS1 titles properly and others saying that it works just fine with the correct adjustments. What do you think? I'm especially intersted in PS1 emulation on Old 3DS 'cause I don't own a New model.

Let’s be positive, I say it’s going well

(Sorry for not giving a proper answer)

I don't think O3DS can play games at full speed. I remember I played many on New 3DS and they all ran at full speed though. All the games I tried totally playable on N3DS. with the proper settings.

There are probably thousands of other very enjoyable games that you could run on an o3DS.

If you want to run PS1 games on a portable console that badly, just get a PSP or a Steam deck or something.

My friends bully me cause I use mine for ps1 games more than for 3ds stuff. I just don't really know any 3ds games lol. 3D games can be slow, and there are flashing screens in some games for me. But other games run at locked 60fps (off the top of my head, the jojo ps1 fighting game)

I have the n3ds.
Ape escape is a bit choppy/laggy for me.
Soul reaver audio skips.
FFVII has visiual flashing rly bad for me but others claim it runs almost 60fps for them.

If I have a game I can tell you how its running for me.

PS1 emulation on a (New) 3DS is a 50/50. I tried 6 games and three of them didn't work or were completely unplayable. The other 3 ran pretty good.

I don't think an Old 3DS has a chance. It's just too weak for PS1 emulation.

I use the (New) 3DS regularly to play PS1 games, I have to say the experience has been quite good for me and every title I tried so far ran fullspeed for me (although I haven't tried games with heavy use of FMVs).

It is important to note that running cue/bin images in the 3DS will introduce performance issues, this may have to do with the small amount of RAM or slow IO speed of the SD card. In order to improve performance, I recommend using MAME's CHD format that compresses multiple disc image files into a single package (this is similar to the PBP format widely used in the PSP, which is also compatible with PCSX Rearmed).

For converting discs to CHD format I found this nice guide: https://wiki.recalbox.com/en/tutorials/utilities/rom-conversion/chdman

You can also try compressing to CHD using the newer zstd algorithm which seems to be faster and smaller than LZMA in some cases, for more information you can read this GitHub issue: https://github.com/libretro/pcsx_rearmed/issues/575
