    NG.DEV Team MVS Carts - Nuances/Issues

    If it's working for you then consider yourself lucky, as it's really a crapshoot whether the games will work together or not, especially once you start getting aftermarket carts involved. You even mentioned they crash sometimes.

    Convert PAL Neo Geo AES to NTSC? (NEO-AEC)

    3.58MHz for NTSC, 4.43MHz for PAL Unrelated to the above crystals by the way, I prefer the slightly faster crystals to the 24 Mhz ones for better picture quality, but they will both work, and won't cause the stability issus you're having. You can build replacement oscillators that customize to...

    Did you reflash the same chip? Could be the chip.

    Convert PAL Neo Geo AES to NTSC? (NEO-AEC)

    The "-PAL" is marked on the AC adapter, but not on the bottom of the console. After all, the console only cares what voltage it's getting, not what kind of mains you're using. Here's an example PAL console: https://www.neostore.com/PAL-220V-Neo-Geo-AES-console-system-boxed-p/569.htm Again...

    Isn't this a PAL system? PRO-POW is only for Japanese systems. https://www.firebrandx.com/aespsuguide.html

    MV1FT Watchdog repair

    Wow, that sucks. It's got to be something really minor. These boards are old, but leaving them on all night shouldn't hurt anything. I would gently re-seat the bios to start.

    PGM multicart interest check

    lol. Same two games I'm missing. I gave up on completing the set, as it's not that important to me.

    Yeah, I think most aftermarket shells are pretty crummy.

    Aliexpress MV1B expansion board BIOS?

    Oh, I see. So this is meant to sit below an MV1B. Someone really needs to basically just create one like the NeoTurfMasta one for CMVSes that has a smaller form factor and a socket for the bios.

    Aliexpress MV1B expansion board BIOS?

    Thanks for sharing, didn't know about this. It's massive for what it does. NeoTurfMasta's memory card support board for 1B/1C that never went into full production was quite a bit smaller, and had a standard socket for the bios. The inclusion of the LED display makes it seem like this is meant...

    Aliexpress MV1B expansion board BIOS?

    Thanks for sharing. Do you have the Aliexpress listing? I don't think I've seen these boards before. I kind of wanted to buy one of those CMVSes on Aliexpress just to see what it was. The ones with the memory card slot sticking up on top. Do you have more photos and info on this expansion you...

    You mentioned getting a Unibios recently. Did you reset the backup ram after installing it?
