      @gamez-fan sorry, but please don't mention rom sites: https://retropie.org.uk/forum/topic/2/forum-rules

      The site in question is not a download site per say it's an Xbox dev forum, anyway please just remove my account from here as i've had two reprimands
      in the space of a couple of weeks now and yet i've never had one telling off on the many other sites i've been a member of for over a decade now!!!.

      A website with a draconian attitude to Romlinks and where you get a ban threat for a miner sweary word is not a somewhere i wish to hangout
      over and out.

        you see @darksavior
        this topic is about adding "non standard" mame 2003 drivers. i do know exacly which rom set mame 2003 supports ;)
        but since kind people adding more unofficial drivers then its clear we need roms other then from mame 2003 set (good example is mslug 4 and 5 which not appear on official list). thats why i've asked (kindly) from which mame set are new added roms ?

            @mitu thank you
            i saw a list, i was reading github about mame2003 etc, but i cannot find anything about changes which are made here.
            the list is only about official 0.78 romset. i just dont know where to look for it.
            thank you anyway ;)

                Big update for Kaneko16 : https://github.com/libretro/mame2003-libretro/pull/284

                @gamez-fan Code via iq_132 reworked for MAME-2003 here is the full WIP.........

                Kaneko Toybox and Calc3 MCU simulation added to the driver which gets some more
                games playable, i then added a couple of extra games some rare prototypes that were dumped
                a couple of years back and finally updated the sound and video handling for some nice
                improvements in that dept.

                when rolling the driver back i made a point of keeping the original Roms from MAME78 for the
                games that worked previously that means only Roms for the new working games will be required

                Original working games no functional change unless stated

                The Berlin Wall
                Magical Crystals
                Blaze On
                Great 1000 Mile Rally (Fixed the parent as it didn't work new Rom required)
                Great 1000 Mile Rally (Evolution Model)
                Great 1000 Mile Rally (USA)
                Sand Scorpian (I fixed the background gfx game now playable)
                Mille Miglia 2: Great 1000 Miles Rally

                New Working games Roms will be needed unless stated

                Bakuretsu Breaker (Rom hasn't changed)
                Bonk's Adventure
                Blood Warrior
                Pack'n Bang Bang
                Wing Force
                B.Rap Boys..??
                B.Rap Boys Special..??
                Shogun Warriors..??
                Fujiyama Buster.??

                ?? denotes im unsure if those ones will work as they didn't in my test build but they may do
                when using this MAME core i guess we'll find out if or when users give em a go.

                Forgot about this driver for Pocket Gal DX https://github.com/libretro/mame2003-libretro/pull/288

                @gamez-fan Might as well add it here to further take advantage of the recent Data East update, i'll need
                to hook in the prot and declare the new games and driver.
                This is the last Data East driver which is backportable from my sources as with deco_mlc.c
                and deco156.c the Arm CPU is not compatable with changes required to make the games
                work, and with regards to backfire.c and dblwing.c some incompatable port tag to handler
                code is the fly in the ointment.

                Bubble Bobble and Operation Wolf https://github.com/libretro/mame2003-libretro/issues/292

                Im not going to add support for any more new games to this core but i still have many
                improvements i can backport like say an updated Bubble Bobble driver which has the
                full dump of the MCU meaning the Emulation of this game would be 100%.

                In this MAME core when playing Bubble Bobble the enemy movements are all wrong
                plus some bonus pickups and the timer dont act correctly it's a similar story with
                Operation Wolf i have a full simulation of the MCU which amongst other things means
                the enemy has found you special levels and the boss at the end of the jungle level will
                now trigger plus there is kill count in each level and when you hit it a barrage of new
                enemies will come at ya.

                This code for the above should be easy enough to add to this core or was that just
                famous last words :)

                Add proper MCU dump for Bubble Bobble https://github.com/libretro/mame2003-libretro/pull/293

                0.107u3: Trinity and Nicola Salmoria added support for real Bubble Bobble MCU. Added M6801 (1MHz) CPU4 and TAITO JPH1011P MCU rom (a78-01.17).

                  ISSUE : NMK16.c https://github.com/libretro/mame2003-libretro/issues/298

                  @gamez-fan The nmk16 driver is in a sorry state at this point in the MAME dev cycle, alotta games dont have sound
                  or bad sound plus there are protection and graphical problems in quite a few others, so im going to attempt to backport mine which will sort all of the above plus add support for a couple more games.
                  The later nmk16.c has the Afega games and code to Emulate them rolled into the driver since these
                  are rubbish games and to significantly cutdown on the workload im going to strip out this code
                  and these games will remain as they were in this core not working in afega.c
                  NMK16 WIP 5 Stages
                  Add NMK004 machine this will Emulate the sound "done"
                  Strip Afega code from the driver and video "done"
                  Rollback my nmk16 driver to MAME-2003 codebase "ongoing"
                  Test all the games after the update "todo"
                  After full testing port the code to this core "todo"

                    Hookup the nmk004 machine https://github.com/libretro/mame2003-libretro/pull/305

                    NMK16 big update https://github.com/libretro/mame2003-libretro/pull/300

                    @gamez-fan Code via iq_132 and reworked for the MAME-2003 core

                    I've updated the driver and video plus hooked up the nmk004 sound core here's a quick breakdown
                    of the changes which have been fully tested beforehand.......

                    Now playable

                    Air Attack


                    Hacha Mecha Fighter

                    Task Force Harrier

                    Thunder Dragon

                    Newly supported

                    Air Attack
                    Hacha Mecha Fighter Unprotected Version
                    Saboten Bombers (set 2)

                    Now with full sound

                    Acrobat Mission


                    Bio-ship Paladin

                    Black Heart

                    GunNail

                    Hacha Mecha Fighter
                    Koutetsu Yousai Strahl

                    Super Spacefortress Macross

                    Thunder Dragon
                    US AAF Mustang

                    Vandyke

                    Roms that have changed

                    Hacha Mecha Fighter
                    Thunder Dragon

                    The one that got away

                    Rapid Hero

                    Unfortunately i cant backport the TLCS90 CPU core which would enable full sound in Rapid Hero
                    from my core as it wont be compatable with this one.

                    • WOAW incredible update i love it, thanks :)
                      So many cool new Shoot'em up to play <3

                      It looks like @gamez-fan reverted all his work and changed his name to ghost over at Github. Kind of a shame as he had implemented some nice changes and updates. Here's the completed DAT. Not that it will do much good now.

                            Looks like support was recently added for 'Donkey Kong II Jumpman Returns'. I've been wanting to play that on the Pi for a while now.

                              Hey Media nice addition I added it to the DAT.

                              I did finish 11/22/63 a while back...finally. I enjoyed it but to much character development for me. My first King novel as I usually just watch his movies. Nothing like a good horror flick. ;) They could have cut the middle 600 pages out and kept the first and last 300. It's was a fairly long book. I am quickly reading through The Maze Runner series before the last movie comes out. I am on book 3 of 6 but I think they only plan on 3 movies as they weren't to popular. I like the books and the build up of the looking-for-a-cure-memory-wipes is thought provoking. I just hope the answer is not a let down. 3 books in and there's very little know as to the why they did it to these two groups of kids but it seems to be the main premise of each book.

                              I combed through this thread and I think I added everything from here so the DAT is current up to around January 1st. Here's the game list and ROMs of around 80 to 90.

                              There are a few ROM files I was never able to locate used for the decrypted versions of Metal Slug 4 & 5. Also Pochi & Nyaa plus the decrypted version. 1 ROM from each archive.

                              Missing ROMs:

                              Metal Slug 4 (Decrypted C) [system: Neo-Geo - folder: mslug4nd - parent: mslug4 - size: 70mb]
                              missing rom: ms4n_s1.rom [size: -] [CRC32: c4f4ed0e]
                              
                              Metal Slug 5 (Decrypted C) [system: Neo-Geo - folder: mslug5nd - parent: mslug5 - size: 82mb]
                              missing rom: ms5n_c4.rom [size: -] [CRC32: 899fb2af]
                              
                              Pochi & Nyaa [system: Neo-Geo - folder: pnyaa - size: 23mb]
                              missing rom: 267-v1d.bin [size: -] [CRC32: 1ac7db71]
                              
                              Pochi & Nyaa (Decrypted C) [system: Neo-Geo - folder: pnyaan - parent: pnyaa - size: 23mb]
                              missing rom: 267-v1d.bin [size: -] [CRC32: 1ac7db71]

                                I couldn't agree more.

                                hey could have cut the middle 600 pages out and kept the first and last 300.

                                My uncle has read all of King's books and that might very well be the criticism I hear from him the most. I've read a few myself, 11/22/63 included, and he does tend to be unnecessarily over-descriptive which adds a lot to the weight of his books.

                                I am quickly reading through The Maze Runner series

                                That series has escaped me, but I've been meaning to check it out. It sounds like something I might like.

                                  That's probably a better way of wording it. I knew more about "Jake & Sadie" then I needed to know to make for a good story and some other pieces just seemed to be background filler with nothing to do with the main plot. It's ok for books but movies just give me enough background to make them interesting/care and keep the pace moving. Make those 2 hours interesting. :)

                                  I've read almost every Louis L'Amour book and he does something similar-ish that I always found interesting. If he described a canyon, cave, water hole or a certain piece of country, etc. he made it geographically & historically accurate as possible. He would do a lot of research before writing.

                                  I can't make no promises on The Maze Runner...yet...but if you read the first book you'll know if you want to continue to the next and learn about the "Flare". Side note Ready Player One is shaping up to be interesting and looking forward to seeing it in another month or so.

                                    I'll give it a look for sure. I'm excited for 'Ready Player One' as well. Everyone I know keeps saying they hope it turns out better than 'Ender's Game', but that project was plagued with issues from the beginning. RPO seems to have had a mostly trouble-free production and as you say, it appears to have shaped up well. Here's hoping it'll rock the socks.

                                      It looks like @gamez-fan reverted all his work and changed his name to ghost over at Github. Kind of a shame as he had implemented some nice changes and updates. Here's the completed DAT. Not that it will do much good now.

                                      Thanks a lot :)
                                      You really make a good work with this DAT file, it will help :)
                                      Do you think you will continue to update it ? ...
                                      And why not add your link to the MAME GIT page ?

                                      It can be for users interesting to update this page : https://github.com/arcadez/-mame2003-plus-libretro/blob/master/README.md
                                      Add you link and explain quickly what add this MAME version from the original one.

                                      Life is game, just play it !

                                        The only way these ROMs are going to appear is if someone digs out exactly the right version of Kawaks (whether its original or coinops xbox builds) from about 2004. I don't have much hope they'll surface at large on the internet at this point.

                                          I think the work @gamez-fan does is great but he doesn't really have a "procedure" and that last big NMK update I had no idea what ROMs I needed to add/update. I don't need a lot of information but the ROM name and driver minimally.

                                          I know this a gray area but if he was testing the games as he was adding them it would have saved hours to have access to the ROMs to build out a DAT. I don't think he was testing his changes even. Building from scratch is incredibly banal. I think I spent around 40 hours total on this project as so many DAT entries were done manually without the ROM sets.

                                          Here's what one game entry looks like:

                                          When you multiply it by 90 it starts to become a fairly large file. Plus you need to tag the BIOS, clone ROMs, merge files, samples, etc.

                                          Many of the drivers only had the CRC listed (no size or SHA1). So I would hunt for the ROM and back fill the missing information. Basing the find purely on CRC (which can lead to incorrect files) as I believe that's how ROM management tools do it. They are capable of renaming files so matches are based off hash mainly.

                                          The other information is not critical but for completeness and it almost removes any chance of changed, duplicate or corrupted file CRCs due to all fields need to match for each ROM file (CRC, SHA1 & size). Again with access to the working ROM none of this information is needed as it's easy to generate the data from the files themselves. With a properly named ROM it's quite easy to build the main file and then add the other information.

                                          If you read through this thread on Github it might help explain. Some suggestions were made to try and streamline the process but not even he had access to the ROMs he was making changes for. I do appreciate his work but I think he prefers to be "spontaneous" in his project and I get that too as he's doing it in his spare time.

                                          EDIT: Shortly thereafter he removed his account. I think that's what Github does. Is rename it to "ghost" when deleted? I thought he changed his name at first as all his threads now say ghost. :)

                                            @markwkidd said in lr-mame2003 driver improvement and backport:

                                            The only way these ROMs are going to appear is if someone digs out exactly the right version of Kawaks (whether its original or coinops xbox builds) from about 2004. I don't have much hope they'll surface at large on the internet at this point.

                                            I agree I spent a lot of time looking for those last few files. Even on archive sites. I came to the conclusion they were modified originals for Kawaks, etc. For some reason many Asian sites come up in searches but I couldn't even get a hold of the programs (patch executables) to modify the original ROMs.
