Request: add Duckstation PSX emulator

George Spiggott

@clyde and @Folly I finally got round to sorting this. It took me (or rather the computer) an hour or so to convert the 45 games in PBPs to BIN/CUE and then to CHD.

CHD = 14.2 GB
PBP = 16.3 GB
BIN = 23.9 GB

Also I now need to create an M3U file for the one multi disk game I have.

Folly

@george-spiggott

Which programs did you use, eventually, for the conversions ?

George Spiggott

@folly PSXPackager and Chdman.

Nice to hear that my suggestion worked. 😊

George Spiggott

@folly I have had one failure, Tomb Raider, no doubt because of its unusual multi .BIN file system. I had to source a new copy of the .BINs and convert them directly to .CHD.

Folly

@george-spiggott
Looks like you have done pretty good then. 👍

duckstation now supports PBP, fyi

@dankcushions .pbp file not show all games in list.
Linux mint 20.4 x64.
Edit: Dont run any game in .pbp file...

Hello, does anyone know how to tell me how to compile the source code of the version for Linux?
I've tried, but I don't have the necessary knowledge.

i'm not sure what you're asking me. it was just added upstream but you'll have to manually build it yourself if you want to test the feature, but it is working for others. it is not part of retropie yet and we don't support it.

@wmarcio create a file lr-duckstation-psx.sh inside your RetroPie-Setup installation:
~/RetroPie-Setup/scriptmodules/libretrocores/

And paste this inside:

#!/usr/bin/env bash

    mkdir build

    mkRomDir "psx"
    ensureSystemretroconfig "psx"

    addEmulator 0 "$md_id" "psx" "$md_inst/duckstation_libretro.so"
    addSystem "psx"
}

Now run retropie-setup.sh and navigate to "Manage packages -> exp"
Scroll down and you should see "lr-duckstation-psx", go inside and "Install from source" like any other package.

To set duckstation as your default psx emulator, run any psx game from RetroPie interface
When this window appears, press any key, then you will be able to select duckstation.

Don't forget to save any state/memory card before switching just in case.

it runs on ARM, not just aarch64. in any case, i think this will suffer the same retroarch GLES bug as i fixed, but isn't in the retroarch version used in retropie (we're waiting for the next retroarch release).

i really would suggest people just wait for this to be added properly.

@dankcushions I agree, I just helped @wmarcio compiling duckstation code, as he's using Mint x64
My script is just a temporary solution :)

wmarcio

@ericus858 Thank you very much for your help.
In fact, I am interested in compiling the Github source code and using the emulator outside of Retropie.

I want to compile from this link: https://github.com/stenzek/duckstation

Anyway, thank you very much for being willing to help.

dankcushions

@wmarcio the github has both build instructions and
pre-built binaries. if you're running linux mint then you're sorted - just get the linux binary.
