    Neo carts and enhancement chips?

    Could Neo games have been able to make use of extra enhancement chips on the game's PCB like the SNES?

    A 3D chip or just something to boost stock hardware performance would have been interesting to see.

    Sure they could have done this stuff. A cart with RAM for tile data would have allowed them to do some tile (sprite) rotation, and casting or a number of other tricks. They could have even offloaded some 3D calculations to a CPU on the cart board to handle this process. It would only be limited to what the developers could come up with.

    One of the features on the first gen motherboards (at least AES anyways) was the audio pass through on the cartridge port. This would have been great to have on all motherboards. We could then use custom audio hardware from the cartridge to do things like audio streaming (mp3 game tracks), sound mixing, etc...

    That's exactly what WaterMelon are doing with Paprium. It's a neat idea, but the Neo can produce nice sound on its own, unless you really need that crystal clear PCM that lasts for hours.

    Does the MGS have the audio pass through? I still have questions about the NGDevTeam music.

    Looking at MVS cartridge pinouts, it doesn't look like there are any audio pins at all. They are present on the AES cartridges, but their use is limited to an early board revision? Get NeoBitz or some other Neo dev in here, so that we can get actual answers. NeoSD or Raz, maybe?

    The way the Neo works with graphics, I don't know if you'd need a CPU on the CHA board. Maybe to do polygons, but clearly all you need is a ton of ROM and the Neo can throw it all on the screen.

    Isn't that pretty much what NG Dev Team is already doing with their cartridges? I figured they were using a ton of ROM for rendered CGI animations. There's powerful FPGA processors in their carts too, but it's unknown if their FPGA is doing anything beyond data decryption and multiplexing, like processing game logic or graphics.

    I think it would be awesome if Cuphead was ported to the Neo (could definitely do a great port, with all the animation and such), perhaps using some chip to hold CD quality audio to be streamed, in stereo, instead of compressed audio used in later releases for the hardware.

    I have thought about this quite a bit. I have come to the conclusion that in theory anything is possible provided it is output as a set of sprites at the native neo geo resolution with the right colour set. In theory you could in effect have a mini computer in the cart producing what ever you want be it 3D or whatever. All you would need is a chip to convert the output on the fly to sprites for the neo geo to display and since high bandwidth streaming is what the neo geo is about it should be possible. Not sure about the screen lag and maybe I'm wrong but I think the architecture in effect makes anything possible provided you apply the constraints above. It's what makes the Neo such a powerful machine.

    Why would anyone want that, if Cuphead can already be played in its original quality on other platforms? To me, enhancement chips are for allowing the artists and programmers to extend hardware's original capabilities, while still being true to the platform in some way. I would totally dig enhancements which would bump up sprite animation to a CPS3 level, while offering more background layers, and maybe an extra audio channel, but things like "let's make it play Doom" are pointless from the gaming standpoint [while extremely interesting from a technical standpoint].

    Hook line and sinker! Haha

    The animation wouldn't look right with the Neo's lower resolution.

    You could have pointed out any of the 10,000 reasons that wouldn't work, but no, you chose artistic integrity above everything else. I respect that. Classy.
