    @gamez-fan Have any changes been made that might effect games made by Irem and Tatio? I have about 150 games running on mame2003 and they all work fine on a stock 4.3 image. However after updating mame-2003 a few times, not many of them work anymore and I keep finding more that don't. Mainly by those devs.

    I am using the correct romset etc. I just thought maybe some drivers changes may have caused this?

    I made a thread about it here:
    https://retropie.org.uk/forum/topic/14529/help-retropie-4-3-some-mame2003-roms-not-working-after-update

    Thanks :)

      @gamez-fan can I make a request that your PRs have all the changes needed for a particular game (or set of games) in one PR? right now it looks like every file change has one PR which makes it difficult to test.

        @gamez-fan Thanks, but unfortunately, it fixes none of the audio issues the system16 games have. Altered beast is still unplayable. Maybe the bootleg works but I haven't tried that. It made Shinobi worse. After finishing level1, the same level repeated over, I died, then level2 loaded. I was using shinobi.zip. I haven't tried shinobi in months so I can't say for sure your work caused the level to repeat.

        I'm using version bc76b23, which matches the latest commit.

        That's a real bummer as it was a ton of Work to update the Sega core and get it on a par with the Xbox MAME port in which we see none
        of the sound, graphical and game problems you mention above im at a loss here as to why with the exact same code more or less
        the games are fine on the xbox but not so much on the Rpi.

          No changes have been made that would affect the games you mention, listen though when i make any changes to my Xbox MAME project
          that involves adding new game support then we always have to delete the previous save files the Emulator creates as this can mess up Rom
          loading.

          Try removing your MAME emulator save files and then reboot it again and hopefully this should sort the issues but i'll certainly look over
          my commits again to make sure it's nothing i've done which is causing this.

                Ok i had to revert the Sega Core Update as it broke all the System 16 / 18 games i've fixed them now, a real pity as it was a fair bit of work and those
                MAME improvements would have been a real boon in the end i think some of the memory map handling was just not compatable with the
                MAME78 source.

                But hey it's not all bad news as there are two new playable games.............

                Sonic Boom

                ALTTEXT

                Runs like a dog on lesser hardware when using FBA but plays a treat in ole MAME, mind and grab the decrypted Roms
                and drop em in sonicbom.zip for this to work as we're bypassing the FD1809 encryption.

                FixEight (Bootleg)

                ALTTEXT

                The original version of Fixeight is not playble in MAME78 but the bootleg plays quite nicely after i added it

                  @gamez-fan No worries. You tried. One of these days I will have to test out speeds to see which emulator is the best for system16. I might have to go with mame2010. FBA is too slow, even after they fixed their audio problems.

                  Do you look at fba too? If so, a small request, on why the konami (tmnt1,2,sunsetriders,mysticwarriors, simpsons,etc) and banpresto games (sailor moon really;P) games are faster on fba2012 than standard fba? Missing optimizations? Just more accurate emulation?

                    Just a heads up with regards to the sound being better in MAME-2003 the Shinobi Bootleg is the version to play.

                      No hope to improve Shinobi, E-swat sound problem ?
                      And fix Altered Beast ? because this one is not playable :(

                          Ok thank i will try it.

                          https://github.com/libretro/mame2003-libretro/pull/212

                          @gamez-fan This will fix the sound and the sub CPU reset line getting lost in transet slowing the game down to a crawl

                            @gamez-fan Two new Joystick versions of Cabal which have an extra button for rolling, the bootleg has this setup also but the official versions are 100% soundwise.
                            The version i remember from the Arcades back in the day it's not the same without the roll button.
                            Anyway this change is from MAME120 the joystick version becomes the parent and the US set's 1 and 2 are now the trackball versions with just a slight Rom name change the bootleg stays the same.

                              Did you test this on Retropie/Retroarch ? I have the same issue, when you hit the enemies they freeze and you can walk through them. I think the game works fine on all systems except the Retroarch version. A lot of games in lr-mame2003 don't work properly whereas the original MAME 2003 versions work fine. Probably something wrong with the Libretro code.

                                No a MAME72 build on the Xbox, i just wanted to make sure folks weren't using the non working version 2 Romset.

                                Alotta the input and graphical code has been changed, i suppose so that it's endian safe for multiple platforms, problem is it might be these changes
                                which will likely be the cause of the Bally Midway games refusing to coin or locking into service mode on boot or the graphical problems your getting
                                with Altered Beast or as you say lots of games just plain not working all of which you dont get when using the original MAME78 build.

                                It would require some dev's with a bit of free time on their hands and a fairly large team of testers to put this right.

                                  If you can help write a description of the work in the github issues, that would allow bounties to be raised for a bigger project.

                                    @gamez-fan The games will sound way better now, but folks will need new samples which are quite
                                    easy to obtain via Twistys site FBA for example uses the same ones.

                                    • 0.86u3: Donkey Kong sample improvements [Peter Rittwage, Derrick Renaud]. Added samples (run01, run02, run03, jump and dkstomp.wav).
                                    • 0.86u3: Peter Rittwage and Derrick Renaud replaced the old climb and walk sample with three different samples. Replaced climb- and walk.wav with climb0, climb1 and climb2.wav and walk0, walk1 and walk2.wav.

                                    Code via BritneysPAIRS

                                      @gamez-fan Code is via iq_132 and gives a large speedup and reduction in the overall memory requirements
                                      when loading the graphical Roms for Street Fighter, this works very nicely on the Xbox im sure it'll
                                      be likewise for all the platforms that use this MAME core.

                                      Ok this is defo my last commit!! i simply forgot about this code which im sure you'll
                                      agree was worth porting across.

                                        @gamez-fan 0.94u5: Aaron Giles turned off debugging code in the hotspots, giving a huge speed improvement to the V-unit games.
                                        To play these games you need to map a button for "Enter" as this is used as you go through some setup configs on first boot after that these are saved for every time you start the games thereafter.

                                          To play these games you need to map a button for "Enter" as this is used as you go through some setup configs on first boot after that these are saved for every time you start the games thereafter.

                                          Would you be willing to log a github issue for this? It should be possible to set up a default key for Enter. I don't have time this month but I may be able to take care of that eventually.
