Tekken2 + lr-pcsx-rearmed = vertex explosions

[pxi]

Hello all, this is my first post here. :-)

Last Friday I ran a full update of a Retropie running on a pi4. This updated several emulators, among them lr-pcsx-rearmed.

The problem is that now my Tekken 2 ROM has distorted graphics similar to the ones on this post on reddit. The OP there solved the problem by reinstalling everything, but I think a simple downgrade of lr-pcsx-rearmed could do the trick?

I've checked and there are no other emulators for PSX available for armv7. PCSX ReARMed and lr-beetle-psx complain about incompatible tags and lr-duckstation is nowhere to be found in the package lists.

Any help on the subject is greatly appreciated.

i can confirm this issue.

I find a working version that looks that is working with the game. To downgrade follow this steps :

From the terminal run this command :

sudo nano /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-pcsx-rearmed.sh

change the line :

rp_module_repo="git https://github.com/libretro/pcsx_rearmed.git master"

to be :

rp_module_repo="git https://github.com/libretro/pcsx_rearmed.git master e007af2"

then press Ctrl+O and Ctrl+X to save the change to the file.

In the end choose, to install the packages from source .

For lr-duckstation you have to install it manually because it is removed from RetroPie.

From my personal back-up, you can download the lr-duckstation package and install it, instructions:

1. Downoad the zip file from here( after 24 hours, the link it will expred) : https://easyupload.io/gmyq1e / unzip it.

2. Put the folder lr-duckstation here :

/opt/retropie/libretrocores

3. Put the lr-duckstation.sh here :

/home/pi/RetroPie-Setup/scriptmodules/libretrocores

4. From the terminal run :

cd $HOME/RetroPie-Setup

sudo ./retropie_packages.sh lr-duckstation configure

You are ready. You can delete the lr-duckstation.sh to not have the error messages during the updates.

It may also be helpful to file a bug report here: https://github.com/libretro/pcsx_rearmed/issues

Since it looks like the emulator has been getting more updates recently, hopefully it can be fixed.

@windg thanks so much for your help!

I've installed lr-duckstation and it works like a charm. I also ran the downgrade of lr-pcsx-rearmed, but so far no luck.

[EDIT: I'm an idiot, I forgot to compile it from source. On a side note my controls have been reset, all though my saves still work.]

As @quicksilver suggested I've copied and edited version of this post on their issues tracker here. And hopefully I can assist them if they need more information to fix the bug.

Thank you again for your help :-)

@pxi You can add a verbose log to the issue - toggle debugging from the Runcommand menu and you'll be able to get a verbose log. This should help to confirm there's no other issue involved (wrong BIOS, image, etc.).

@mitu I've asked them if it would make the situation clearer, and I'll revert the changes to provide a log if they request it.

Out of curiosity I tested Tekken 3 (I don't have Tekken 2) and I did not experience this issue. Do you have Tekken 3? If so could you test to see if it has the same issue for you?

Scratch that looks like there should be a fix now: https://github.com/libretro/pcsx_rearmed/issues/613

You should just need to restore your script module to original version and update from source to get it.
