CPS3 CHDs in MAME?

[Jorpho]

So I saw a list of the CHDs in the current MAME romset and noticed that every CPS3 game is listed. Curious, I went to UnMAMEd (http://unmamed.mame.net/non_other90.html#SF3), which says:
This will never work (encryption etc.) MAME driver does NOTHING, for reference only. Anyone know what's going on here? Is it not unusual for hundreds of extra megabytes to be added to the complete MAME romset for frivolous purposes?

(Not that I have any interest in emulating any of these games myself.)

Some progress had been made on them actually, just not in regards to the encryption. There's a ton of games in MAME that flat out don't work and take up massive amounts of disk space. IIRC a complete MAMEset is like 45gigs or something, and there's really no logical reason why ANYONE should have that unless it's just one more thing you like to collect.

My guess is that they got tired of rom kiddiez begging to get the games working that they just put everything out there and decided to let someone else deal with it...meanwhile MAMEdev has made some fucking AWESOME progress getting some previously-thought-impossible-to-emulate games up and running.

Much like CPS2 encryption, it's all a matter of the right person figuring it out. Shame that CPS2 encryption still hasn't been truely "broken" by anyone other than Raz...XOR files are such a dirty hack :(

Tangent: Anyone else a big fan of M1? Arbee added Daytona USA 2 and Scud Race to the latest versions. Rock the fuck on. Say what you want about Winger being lame (which is typically influenced by that terrible piece of shit show Bevis and Butthead), but his work on those two games is fucking k-rad. Winger rocks.

M1 updated!? :eek 2: Is the new version up on R.'s personal site, or somewhere else?

Razoola is awesome. He recently said that it may be possible to fix CPS3 carts to work without the batteries, like he has done with most CPS2 games. He said it may even be possible to run all CPS3 games off the same cart, just by switching the CDs.

PS. Beavis and Butthead are hilarious.

Oh i agree, he's done quite a bit for CPS2 collectors. I just wish someone else would figure out the encryption on it so that it could be properly emulated. Thank god Neo Geo encryption was broken quickly so that we wouldn't have to put up with the same crap for that as well (the downside being that it led to the games being bootlegged and the rom dumps being hacked to work in NeoRageX).

p.s. Bevis and Butthead is even worse than Clerks: The Animated Series.

There's a good reason non-working stuff is put into MAME. It's a documentation and preservation project, not a game playing project. All the information that's available is put in there in case someone else wants to take a look at it, or if someone needs to fix their board. Besides, all but one of the CPS3 games was ported to the Dreamcast, anyway.

M1 is one of the greatest and most unique pieces of emulation software out there -- all it needs is Winamp integration, which is being worked on. :) Apparently it's a bit crashy at the moment, though...

In my book, that's a huge boon for B&B. Clerks rocked.

I thought the XOR tables were ultimately the equivalent of the data in the suicide memory (or whatever it is called) on the CPS2 board. In any case, wouldn't that data have to be dumped in order for there to be "true" emulation?

And just out of curiosity, where does the complete MAME romset come from, anyway? Are there simply people with no qualms about copyrights who have access to the same boards and dumping equipment as the MAME dev team?
