      @bobharris @tiagop I tend to compress them to PBP files (PSX2PXP files). Saves space and I haven't had an issue with loading times despite the compression.

      I'll give TR2 NTSC a go, see if I experience slowdown. I'm sure I've got it somewhere :P

        @stoo Thank you, by the way I still haven't mention that I'm using the ROM Tomb Raider 2 (v1.3), I can't remember which version I used on the PSP

          @tiagop That's exactly the version I'm using.

          Ok, the slowdown is the game itself. Tried it on my gaming PC which can run lr-psx-beetle without any problems. Native resolution, native everything, there are HUGE framerate drops in the training section.

          Game should be called Tomb Raider II - Starring Least Optimized Engine and Least Responsive Controls

            @stoo Thanks for testing it, then surely the problem is in the ROM? Glad the problem wasn't on my RPi, I will try to test it later but just the Tomb Raider II (no version thingie) @quicksilver is this the ROM you used since you had 0 problems?

              @tiagop It's the exact same version as I use. There is some judder when panning around in a new area, but that's it and that is normal. Can't you post a video on youtube showing the slowdown?
              Preferably at the worst spot (speedboat venice?).Then we can see if it's normal or not.

                  That's me playing. I had fun, it's been 20 years since I played this part, which you can see as I got lost at the end. :-)
                  But the point of the video is: No noticable slowdown at all when riding the speedboat. And I even enabled enhanced resolution (with speedhack), bilinear filtering (smoothing) and a scanlines filter (which combined is often too much for the Pi 3 to handle on many ps1 games without overclocking).

                  Does the game also gives you the option to play demos of Chicken run and Timesplitters? (Then it's exactly the same version).

                    @bobharris Yes it is the same version, Is that a 1080p TV? My raspberry is rendering at 1920x1080 (defaults), could it be this? In that same zone as the video I notice minor slowdowns on my game yet on your video I don't see them. Thanks for testing it

                      @tiagop Yes 1080p tv and yes 1080p resolution. I only play N64 games on a lower resolution.

                            @quicksilver @bobharris @tiagop @quicksilver I think maybe I've cracked tiagop's problem:

                            tiagop are you using the emulated BIOS instead of real PSX BIOS files?

                            I just deleted my BIOS files to test and the slowdown increased for me like 2x. Put them back and it's fine again.

                            You need scph5500.bin scph5501.bin and scph5502.bin in /home/pi/RetroPie/BIOS/

                              @stoo I only placed the SCPH1001.BIN in /home/pi/RetroPie/BIOS, I will try to get those 3 files and put it there later today, fingers crossed!

                                @tiagop I don't think it will make a difference though as I am also using SCPH1001.BIN

                                  @bobharris It absolutely does. Try it. Play Lara's Home with the 3 BIOS files I mentioned and without. You'll see a huge difference, particularly around the water and trellis climbing areas.

                                    @stoo That's exactly where I have problems! I'm gonna delete the SCPH1001.BIN and get scph5500.bin scph5501.bin and scph5502.bin. I will tell you guys how it went, it can't hurt :)

                                      @tiagop Cool. There are still some framerate drops whenever the mansion is in view (like in the vid below at around 3mins 20secs), but I've tested and that is present in lr-psx-beetle as well, which means it's present on a real PS1.

                                        @stoo Yeah at the area at 3min and 20sec I get the same kind of stuttering and I'm OK with it. But the Venice level for example is horrible, I remember playing it on the PSP and having no issues on any level (can't remember if I played Lara's home there).

                                            @stoo I believe you when you say there is a difference between an emulated bios and a real ps1 bios, but why would there be such a difference between two real bios files? As I said before: I don't notice any of tiagops slowdowns and I share his bios file.
                                            ButI agree it can't hurt for him to try it out.
