    Hi all,

    I'm a big fan of 1on1 Government on Arcade, so thought I'd give the PSX version a go. However the backgrounds don't really work - they hardly contain any detail. I thought this might be a PSX hardware limitation but I've checked YouTube and it definitely isn't.

    YouTube:

    (this level is 11 minutes in but all levels have issues).

    I've tried updating PCSX-Rearmed but it makes no difference. I've tried on my PS Classic with the built in Emulator also. I have the BIOSes on my RetroPie build, I think.

    I just wondered if there were any settings or anything that might make a difference, or if anyone has any bright ideas?

    Cheers,
    Adam

      @adambegood please fill out the read this first information in full, including the verbose log.

      are you running with enhanced resolution turned on? if so disable it - can cause such glitches as per https://retropie.org.uk/docs/Playstation-1/#video-double-internal-resolution

      another thing is trying to run this particularly game in interpreter mode rather than cpu dynarec. you can change in the same manner, although note you’d want to do that per-game, not globally, as the dynarec is typically desirable for good performance.

        @dankcushions

        Thanks for replying.

        I tried the interpreter option, that didn't seem to resolve. I tried turning some other settings on and off. I didn't have the enhanced resolution turned on at any point. The background does show up sometimes but it is not there once the game properly begins.

        Verbose log is here: https://pastebin.com/jNY2GqHi

        Pi Model or other hardware: Pi4
        Power Supply used: Pi Standard
        RetroPie Version Used: 4.6
        Built From: RetroPie website image
        USB Devices connected: PS Classic Controller
        Controller used: PS Classic Controller
        Error messages received: None
        Verbose log (if relevant): https://pastebin.com/jNY2GqHi
        File: (File with issue - with FULL path) /home/pi/RetroPie/roms/psx/1 on 1 (Japan).bin
        Emulator: (Name of emulator - if applicable) PCSX Rearmed
        Attachment of config files: (PLEASE USE PASTEBIN.COM FOR LARGE LOGS) - Let me know which config files you want and I'll be happy to attach them. I can't see a list or anything of that nature.
        How to replicate the problem: Run the ROM, and begin the game. The backgrounds will not appear correctly in-game.

          @adambegood your log is with dynarec still on FYI. another thing you could try is with the other renderers. that would involve changing the graphics plugin in the buildscript
          BUILTIN_GPU=unai or BUILTIN_GPU=peops
          line to change:https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/libretrocores/lr-pcsx-rearmed.sh#L35

          then you'd need to rebuild from source.

          ...or, wait for duckstation, which probably runs this fine, but no install script for the next few weeks at least.

            @dankcushions Hmm, that is strange. I've definitely tried it with and without dynamic recompiler. Sorry for the duff log though.

            I will wait for Duckstation and then I will try the plugin if that doesn't work.

            This is the first time I've seen any issues with PSX emulation, it is vexing.

            Thanks again!

              Great news! Duckstation will be available for the 32-bit RetroPie or 64-bit ?

              Thanks!

              My English isn't at a good level.

                Not a fair comparison, this video uses resolution upscaling, this is not how the game looks on a real ps1, the game on ps1 actually looks like this :

                  @barbudreadmon The actual quality of the characters or anything like that isn't the problem I have. It's the backgrounds, mine just does not display the backgrounds at all while in game.

                  If you look at 12:00 into the video and compare to my screenshot -

                  rps20210422_073305.jpg

                  • there is no bridge or anything apart from the trees. It is very obvious on my Pi and my PS Classic that something fundamental is missing.

                  Here is a screenshot of the same level from Google for comparison:

                    unai as the Graphics Plugin totally fixes this issue! Thanks, @dankcushions !

                      @adambegood just so I understand...the solution was "fix the code and recompile your emulator from source" or am I reading that wrong?

                        Yep, change Line 35 of the scriptmodule to BUILTIN_GPU=unai and then Update from Source. Let me know if you need more detail on how to do that, I am no pro but could just about manage this!
