Dang. I was hoping that maybe there was a way to mess with the really big rom chips or something, since the multis don't have all the games I want. Yet. I'm kind of getting tired of these that have 10+ versions of the same game.

Part of the reason multiple versions of the same game happen is you can add them at lower cost. The reason being that many of those games will have identical Sound or Graphics data or atleast some duplicate that could be reused.

I really wish they would do a separate multicart with games not found on the other multicarts and be done with it.

I wish they would just take the MAME romset of official NeoGeo releases (no hacks, but maybe prototypes) and put that on one cartridge. Then you'd just need one cartridge for your NeoGeo and that's it.

Just wondering, but what does a rom dump look like of one of these? I'd love to be able to replace the roms on one of these with my own multi-game cart. Neo Geo had lots of good stuff besides king of fighters.

It would look like a lot of ROMs appended together... The mapper works by masking the incoming address for the specific ROM size and then it adds an offset depending on where the game is in the series. It would be probably be pretty easy to change the games in these but the only way to do so is to remove the flash and manually reprogram them which is definitely not easy; the flash used isn't going to be supported by any reasonably-priced programmers.

With that in mind, could one of these be easily hacked to just remove the unneeded hacks/dupes, and then just insert the missing games? I know you'd need to buy the appropriate programmable chips, but that should be the only added cost, right? Is there a bios or something that would need to be rewritten on these carts to tell it what games are then on there?

There wouldn't really be any added cost, it's just a matter of reprogramming the chips, but that's no small feat. You'd also have to hack the menu program for the updated games but I suspect that could be understood pretty easily. Debugging however not so much ;)

Good to know it's not impossible. It'd be nice if someone figured this out. I'd immediately buy 2 carts (one?) that had the complete collection with no hacks. I don't even own a Neo yet and I'd buy them.

So you couldn't use SD, CF, etc, but would it be possible to have something like the old GBA flash roms that used a USB writer?

Yup, but you'd need a number of them.

That'd be funny, a NeoGeo cartridge with a ton of GBA cartridge ports to plug in a dozen or more GBA flash cartridges. It would just look so insane.

I meant the technology, not the actual carts silly. Could we have something like that where there was an external writer that flashed the cart?

Not really, it could be done but it'd be ridiculously clunky and expensive opposed to designing it like a V64 Jr. The easiest way literally would be to flash 4 GBA carts (multiplexing a few buses) with the game's ROMs.

I'd guess you'd need 2 GBA cartridges for the C-ROMs since NeoGeo maxes out at 512mbit and a GBA cartridge maxes out at 256mbit without bankswitching. Then one more for the V-ROMs, another for the P-ROMs, so there is your four. But you'd still need a M-ROM and possibly an S-ROM but I'm not sure.
