      I have no idea how 4.6 runs. I accidentally bricked my Pi 4.
      :(

        @IceChes1 I'm really not trying to highjack this thread but I've got to ask. How did you brick a pi?

          Tried to attach a cooling fan to it which somehow fried it.

            Has anyone managed to get any noticeable increase in performance since installing the new v5.4 kernel? I think there are definitely incremental improvements to both kernel and emulator that have allowed me to reduce my reliance on frame skip.

            I did notice that PPSSPP's smoothing seems to have very little overhead and can be used in a few games.

            Currently running:
            Retropie 4.8.9 on a Pi Zero 2W (Overclock Settings: CPU 1400Mhz)
            ES-DE on a GMKtec K6 (Windows 11, 32GB RAM)

              Simply changing "lower resolution for effects" from off to agressive, causes 99% of the games to run full speed while looking wonderfull at 2x resolution without overclocking.

                How do you access that? It is greyed out in PPSSPP.

                  I can't think of any option that would disable it, i didn't do anything special to change it.
                  It's ppsspp not lr-ppsspp.

                    I believe the resolution has to be at 2x (or rather above 1x). It seems to make little sense, but God Of War: Chains does seem better with it... Rather counter-intuitive and I haven't played far in but this does seem to work.

                    Resistance still falls over, but definitely gets further than without the Aggresive setting.

                      In LR-PPSSPP there are three frame skip options. Auto (on/off), Number of Frames (0-9) and Frame Skip Type (0-9). Does anyone know what Frame Skip Type is? and what the 10 different settings do?

                      Also is it possible to activate the post processing effects, specifically FXAA?

                        Just messing around with the PPSSPP, how is everyone exiting their games? As I realised if you add --escape-exit to the option in emulator.cfg it lets you use whatever you've mapped to "pause" to leave the emulator, rather than having to go through the 2 menus each time.

                        The only game I've set to the 1x resolution is burnout, everything else seems to run pretty much fine on 2x with a little audio crackling but no lag and a nice frame rate of 20/30/60 depending on the game.

                          @retropieuser555 I use the center button on my PS3 controller, which I've set as my trigger for hotkeys. It brings up the PPSSPP menu and I exit using that.

                            Has anyone used the CSO format for their ROMs? All mine are in ISO, is there any significant performance issues using the compressed format instead?

                              @retropieuser555 I'm using .cso exclusively. So far, I haven't found anything that didn't work. I would guess, that using compressed files only marginally influences the emulation speed (almost all other emus load compressed files without performance issues).
                              And loading a .cso file is probably still a lot faster than using discs on a real PSP ;)

                                What kind of savings are you getting with CSO? Is it lossless?

                                  @george-spiggott Yes, it's lossless. And although I haven't measured it I would guess you save around 20% - 30% of space. You can change the compression level, but I haven't made tests. I left it at the standard setting in my isocompressor (iirc level 6).

                                    Has anybody been able to play Lunar : Silver Star Harmony with text displaying correctly?

                                    Edit : Never mind, replacing the files under bios/PPSSPP/flash0/font with original PSP font dumps and reinstalling PPSSPP from source did the trick.

                                      @ecto I went through my collection and saved myself about 10GB. I'm having a little difficulty getting some of them to scrape that were fine as .ISOs but otherwise all good.

                                      Incidentally, if I wanted to make a feature request for Lr-PPSSPP where would be the best place to go?

                                        @george-spiggott Thet's good, isn't it? You just made room for 8-10 more games :D

                                          @george-spiggott How much did you shave those 10 GB out of?
                                          I'd be interested to know the exact ratio.

                                            @zering I have 45 roms that are now 35GB combined. They were 47GB, so closer to 12GB saved.
