      I own an Neogeo mvs , reasons slug works slow is due to ram off the top of my head the game is 1gb ish this needs to be loaded into ram.

      The huges neo games will be a problem for the pi. Google the game you want to play look at a aes cart box via images search and it will have the my count on the cover. This will be a guide as to what games could cause issues.

      Also mslug games will have slow downs mslug 1 slowdowns are due to the code in the roms when the game was made (no fix) unless you over clock on pc .

      A lot of neogames had slow down to some degree to be 100% you need it too. I have the orignal hardware and the game will cost you over £500 alone and that's with slowdown . Much cheaper using a pi

        @Charco, do you use any shaders or filters?

            I think maybe in combination with individual gamer's tolerance and perception of "slowdown" we may have different experiences. I don't think Metal Slug becomes unplayable, it's just annoying. I definitely need to go home and try out a few things today.

              I would really like to point this out as a massive Metal Slug fan myself: These games slow-down even in the original/official arcade models. Some issues were "fixed" in Metal Slug X and XX

                No offence but I own the real cart there is no perception there is slowdown it's simply fact your emulation may be 100% accurate if it lags at certain parts (you can use it to your advantage).
                trying to run it with a no lag setup means it isn't accurate but it will sound diffrent due to spead boost and it will still lag but almost 60fps experience but not correct.

                Simple answer to the this is if the sound is still ok but you get some slowdown that's your aim . If it slow all the time it's the piq

                  @vasili that's okay, I was only suggesting that some people may not see it as apparent as others. Nothing wrong with that.

                    Sorry if it sounded aggressive it wasn't my intention. I am not a great writer to be honest :(

                      No problem @vasili.

                      I disabled smoothing and enabled the fps display. It was reporting 59-60fps constantly even when the big boss on the first level came up and caused MSlugX to slow up. I guess it is just Neo Geo doing its thing..

                        @GreenHawk84 Out of interest, have you tried gngeo as a comparison?

                        As many others have pointed out, the originals do slow down at points, so maybe check some YouTube vids to see how it looks on the original hardware.
                        I had the full set on AES and loved them!

                          The big boss battles seem to have the slow-downs for me on the original arcade.

                          Have you gotten gngeo to work on the latest RetroPie builds?

                            as said, lr-fba-next's neogeo CPU overclock option is for exactly these scenarios :)

                            1. load game
                            2. select + X to access RGUI
                            3. options
                            4. cpu overclock - raise it (not sure how much you'd need, but experiment)
                            5. exit, and reload game.

                              So last night I was messing around with Metal Slug, I overclocked NeoGeo in the Retroarch GUI as described here. I set it at 170 and Metal Slug games ran SO MUCH better. One thing though, I noticed this setting carried over without setting it to Metal Slug 2, etc. Will this affect everything NeoGeo or is this something lr-FBA-next is going to hold on to? I don't need anything else overclocked.

                                well, apparently :) you can enable per-game core configs - i forget how without looking. once enabled, at the top of the core options it should say 'save game config' or something like that. that saves it only for that game.

                                  @dankcushions , I'll have to go home and check out something else on lr-FBA-next like Street Fighter III: 3rd Strike and see if that still applies. I'm gonna try to save it for Metal Slug only.

                                    I fired up other games on lr-FBA-next last night and the overclock I did for Metal Slug was saved for the core across all games. Not sure how this affects anything if it's worth just leaving alone.
