Neo Geo AES to Neo Geo CD Project

This forum is for discussion pertaining to homebrew and indie software for the Dreamcast, such as homebrew games, emulators/interpreters, and other homebrew software/applications. Porting requests and developmental ideas are not to be made here; you can make those here. If you need any help burning discs for homebrew software, this is the place to ask as well.

No. Only Capcom Vs. SNK (which was made by Capcom). SNK Vs. Capcom was made by SNK Playmore.

By the way quzar, would it be hard to make NeoDC do the cartridge-to-CD conversion on the fly (byteswapping, trimming, etc. the ROMs), thus eliminating the need for the user to do all this work?

I think it would be easier to just make NeoDC support MVS ROMs. It would then support all of the possible conversion games and quite a few more.

I think quzar has hinted that NeoDC (or its spiritual successor) will do this eventually as well as CPS emulation. Unless I misinterpretted the hints.

CAPCOM VS SNK CHAOS
SAMURAI SHODOWN 5 AND SPECIAL

Most of those games won't fit into the dreamcast's ram, so that's pretty much not possible.

Unless they'd work on NGCD as then they'll work on DC =P

I have a NeoGeo CDZ if anyone needs to test any conversions.

Well, that is true if you load the game at a time, but there is a more advanced way to make the conversion.

Actually some games like Metal Slug (NeoGeo CD version) has loading points. When the game encounters one of them, stops and loads some files from the CD, to play the next mission or whatever.

The point here is we have a one time loading rom (MVS/AES) that will require loading points. Of course, that means program code modification and some research.

Some games are very big so they will require many loading points. This could make these games unplayable, but i think Metal Slug X could be played well, for example.

The key thing is the size and complexity of the working set for a given "level" or "area" or "round". ROM size is one variable, but the more "natural" sequence points (or arenas+characters in the case of fighting games) there are in the game, the easier it should be to hack CD support into it...

Support for something like that could be fairly easily written into the emulator itself. i'm sure many games would become unplayable at some points, but any that have an organized layout for rom data would most likely run fine.

Even if some games became unplayable like you say, I'd still be great to implement that, specially because no one would ask "Where can I find the hacked version of X game to run with the emu".

If I were to do it (i have a fairly well thought out plan on how) it would be on a game by game basis, so it wouldnt really break any games, nor have any uplayable games, some games simply wouldnt be supported =P.

Grimlock wrote:The link is spanish, but basically it says (according to freetranslation.com) that a way to convert AES roms to CD images has been developed. Yes yes i know this is touchy because it suggests warez. But if we can just ignore that aspect of it and focus on the concept of conversion, this topic may remain alive. Do any of you think this is true? And if so...where can we get it? This would make Quzar's (and the other author's) work even more valuable.
Hi, you're right, the article was only focused over the concept of conversion. But I've reading original coder license and you can read that the emulator can't be used in same NeoGeoCD game or Media. The article has been modified in order to keep the rules alive.

Also I would like to say that you will never be able to find any warez at my site, we don't support piracy and there's always a respect for licenses and copyrights.

no sense in getting too excited about this.. let's not forget that some of the most-loved late neo games (SvC and slug 3) are both >60MB..

Oh crap, in my desire to actually think about the nature of the problem, I forgot to embrace the icy bosom of defeatism. Guess I was being careless. :roll:

:guffaw: oh, that was a much needed laugh after the little hit from the first post. kudos to you.

as for huge games, i think that even some random huge games would work, since they use multiple files that are called at individual times.

So that'd be the future of NeoDC, yes? :o A MAME like 16bit arcade emu with NeoGeo and CPS1 emulation? Tell me more :D

Make sure you include Strikers 1945+ and Shock Troopers somewhere on top of your list :wink:
