        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 Breath a sigh of relief it's my final commit .

                        Speedup hack for Street Fighter : https://github.com/libretro/mame2003-libretro/pull/221

                        @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.

                          Big performance boost for Midway V-Unit : https://github.com/libretro/mame2003-libretro/pull/222

                          @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.

                            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.

                              Attempt to fix some reported performance drops : https://github.com/libretro/mame2003-libretro/pull/224

                              @gamez-fan Add in the V-blank changes which were coded at the same time as the video changes happened for the FixEight bootleg i assumed maybe wrongly they were not needed, with a bit of luck this will sort the performance hit in batrider which has been reported on the forums.

                              Also since i was at it i added support for Knuckle Bash 2 which is just a bootleg of Knuckle Bash but
                              unlike that game this one does have full sound.

                                Please can you clarify what is going on with this core? It looks like a lot of untested changes are being submitted, and a lot of reverts for many of them. There are people reporting new issues with the core, and I am considering forking and rolling back this core due to this.

                                eg

                                https://github.com/libretro/mame2003-libretro/pull/204

                                Revert because it broke all the games ? Why was a change submitted in the first place that had so many problems ?

                                    If we can choose what MAME core we want to use in the ES-SETUP ... why not, it's a good idea.
                                    But it is not important for the common users. Nobody is using MAME core from source, it take time to compile, users are using BINary version.
                                    Only testers are trying the source version to try games and compatibility.
                                    If you only make a build when all is done, like you do for ES, it will be enough.

                                      In regards to retropie that is not true. Binaries are updated all the time and I cannot be expected to just know when things are "unstable" - master branch should not be used for experimental and untested changes imho. Also for many platforms retropie is source only. From X86 to ODroid c2/xu3/tinkerboard and RPI on ubuntu etc.

                                      For EmulationStation we have a stable branch - which I specifically manage so that's not comparable.

                                      I'm not going to have a conversation in two places with you so please just reply here.

                                        @buzz Yes for sure, if you update BIN all the time it is a problem.
                                        Adding a DEV branch like we have some on ES can help.
                                        Maybe you can add the dev branch to RP-SETUP like you add the emulationstation-dev last month.

                                          What issues exactly..?? as far as i can tell there were "two" one was infact a problem with a users build rather than my code changes per say,
                                          the other problem was related to the Williams sound core which has now been fixed and BTW i have tested all the code personally.
