Request: add Duckstation PSX emulator

BuZz

@fcibx6r1un it doesn't work flawlessly yet afaik - there are some rendering issues. Btw @dankcushions did the Retroarch changes and some others relating to this, so we are aware of current compatibility etc. It will be added at some point when issues are sorted etc.

Any news on this?
I would LOVE to have this on my x86 Retropie system!

Although no PBP support is kind of a real downside, since PBP has the best compression and is the easiest way to have 1 file per game.

2nd Best ... CHD has better compression and is also a very easy way to have 1 file per game.

Also, CHD is compatible with Duckstation :) FTW !

@dreamcastkid Correct, and the reason for that is that CHD compresses data tracks with 7z's LZMA compression and audio tracks with FLAC, using the best compression for the resp. data type.

And yes, easy it is, too. See here for a script and a one-liner for RetroPie's command shell bash to create CHDs from bin/cue files.

@clyde I'm tempted to convert my collection to CHD. Ideally I'd need a way to convert my existing PBP collection back to BIN/QUE in bulk.

@george-spiggott

It seems this tool can do this ( convert pbp to bin/cue ) ( bulk batch processing with wildcards seem also possible ) :

It seems to work only on windows, here you can find the binary :

Found it in this thread :

@george-spiggott I have no experience with PBP, but according to this and this, they are (mostly?) identical to ISO, and you may be able to "convert" them back to ISO simply by renaming them. At least it may be worth a try.

Clyde

I searched a little and found the QPSPManager. Its available for Windows, MacOS and (alas, only in an older version) Linux.

It requires a graphical desktop environment, so even its Linux version shouldn't run on RetroPie without installing one, or using another Linux distribution.

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. 👍

dankcushions

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...

wmarcio

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

}

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.
