    AES Multi Cart Troubleshooting and help

    Power the unit on with the AES Multi connected and measure the voltage across that capacitor. Measuring the resistance between the cap pins on this context is meaningless.

    CPS2 Roll-Up Packs: All roms for the CPS2 kit

    Not really, some of the newer hacks are patches made on top of encrypted sets so they can be used on original protected boards by just swapping EPROMs out. Beware of that. Only the CPS1Q conversions are 100% sure to be decrypted.

    Samurai Shodown V Perfect on real hardware?

    it was ack who posted a quick set of linux commands to scramble the rom using the same scramble as samsho5sp.

    Samurai Shodown V Perfect on real hardware?

    We had to scramble it to run in MAME, nothing more, nothing less. Samsho 5 and Samsho5 SP use different scrambles each.

    Samurai Shodown V Perfect on real hardware?

    That does not exist in the form you are expecting because it's the result of applying patches to the ROMs we're playing with right now and we're quite not sure how to get these patches out of the emulator right now... :)

    Samurai Shodown V Perfect on real hardware?

    It does not, we already know that. It matches a location test photo from circa 2004 (check thread backlog).

    Samurai Shodown V Perfect on real hardware?

    Yep, that is why I put screenshots with both japanese and english logos. Well we need to figure out how to patch the CROM and SROM then...

    Samurai Shodown V Perfect on real hardware?

    Okay, I just made this work on the MVS multi. I was assuming the P ROM from the release was scrambled, which is not the case. You only need it scrambled to make it work with MAME. Because of the C-ROMs not being CMC encrypted it might not even be a good idea run it on MAME with the Samsho5sp...

    Samurai Shodown V Perfect on real hardware?

    it works better if you change the banks at the second chip like this: cat prom.ak prom.ad prom.ac prom.af prom.ae prom.aj prom.ag prom.al > 272-p2.sp2 Thank you for figuring out how to convert the scramble. Unfortunately you swapped out a single bank pair on wrong positions. Now it works...

    Samurai Shodown V Perfect on real hardware?

    Guys, focus on de-scrambling the program roms first. old MAME release neocrypt.c, this code de-scramble the released samsho 5 Special, This ROM has a different scramble which is why it tosses a bank error when you try to boot it on mame while using the scramble from another game. void...

    Samurai Shodown V Perfect on real hardware?

    SSVSP has PCM2 with P-ROM scramble. The right way of going about with this (if the goal is run this as SSVSP on mame) is figure out this particular rom scramble first, unscramble it and finally scramble it with the correct scramble for the old SSVSP ROM.

    New CPS2 Multigame Firmware with Key Writing!!!!!!

    You don't need to remove the wires to update when using a SD card. Only if you're updating the bootloader using the discovery board (because the testpoint pins are the same ones used by the discovery to connect to the STM32).

    New CPS2 Multigame Firmware with Key Writing!!!!!!

    If you update the firmware you have to update the wiring too because the pin assignments changed. If the wires are connected wrong the CPS2 board may not reset during flash load or key programming. If the key wires are not set up correctly the encrypted roms also won't boot since the CPU won't...

    card dispenser capcom

    Actually some games you can just change a byte somewhere on the rom to change the region. I suggest you instead write all brazilian roms because if you don't do that the memory test may fail.

    card dispenser capcom

    Nothing is inserted. The USA/JPN/EURO ROMs have the code to access the card dispenser, they just don't use it. Change the ROM region to BRAZIL and the card dispenser function will become available.

    CPS1 Strider Hiryu - rom swap possible to make USA version?

    Because your game is a bootleg, I suggest you take out the roms 22 and 23 (CPU program) and check against the MAME files. If they are identical then it is unpatched and the USA ROM will work straight. If the rom is patched, you will need to use a patched set as per the suggestion given...

    CPS1 Strider Hiryu - rom swap possible to make USA version?

    Actually, you can use unpatched PRG ROMs but you will have to shuffle the GFX EPROMs around the sockets (chip numbers do not match the board sequence numbering labeled on the mame zip, which pertains to the original board the game released on...) because the B BOARD may be electrically different...

    Multi sound cutting out or hanging

    I can't help anyone on Facebook because I've never been on Facebook. I've been helping on Twitter at most because it's the only social media I use.I don't check this site often but when I do I look all the threads with mentions for me.

    WTB: Ricoh RF5C68 (or ASSP 5C68A) to fix my Moonwalker

    MEGA-CD/SEGA System 32 use a bespoke variant of RF5C68 called "RF5C164" (315-5476/315-5476A) which SEGA has the Ricoh datasheet for it included on the MEGA-CD programmers kit. While it is a improved RF5C68A chip, it has physical differences on how it outputs the audio. It is meant to be...

    Multi sound cutting out or hanging

    I've never seen the issues you mention on my multi and I used many different B boards with it. A boards too. Perhaps your multi unit has a faulty buffer on the Z80 portion? Also the Z80 on the CPS2 is running at 8Mhz, the Neo Geo one is rated for 4Mhz and it runs at that speed. I don't see...
