Unemulated systems

I know there is an unemulated MAME games site that shows games not yet emulated. I was wondering about the systems that haven't been emulated yet. Like for example, Bandai's Playdia, Phillips CDI, 3d0, etc. Is there any place that keeps track of these systems?

Free3DO is an emu that's currently being developed. I think there are beta releases out there. Check the main ZD site it may have it.

hey, and also all of those gooberish little game & watch-engine type things like "wwf wrestlemania" and "double dragon" and "the little mermaid" and whatever else that you used to see in the toy department... "handheld games" ...you know, that had probably about 2k of code, and 4 or 5 little sprites that had maybe 3 different positions each.. :)

haha, for some reason, i'd love to see those emulated. :) complete with scans of the original... unit or whatever...
mm, nostalgia.

I always wanted one of those, just to see how shitty the Zelda sequels really were.

The two unemulated systems that I am most interested in are the Saturn, for which Saturnin is progressing quite nicely, and Sega's System 16 arcade board (and close variants), which apparently was once partially working in MAME but was removed so it could be rewritten.

I've been really curious about MegaLD games for a while now. For those who don't know, back in the days of the Genesis, Sega licenced out their hardware designs to other companies which would build their own variants of Sega's consoles. The most famous is probably the JVC X'EYE, a Genesis/SegaCD combo unit. Pioneer released their own Genesis/CD combo that was part of a laserdisc unit, and a few games were made to run off laserdiscs instead of CDs. These were mostly just FMV games and the like, but apparently there was an RPG and a shmup for the system as well.

I suspect adding MegaLD compatibility to Gens wouldn't be terribly difficult, relatively speaking, but it will probably never happen anyway.

Oh yeah, classic LCD games. I had Double Dragon and a few others. Boy did they suck ass or what, almost has bad as the Tiger R Zone, which I doubt will ever be emulated. But that doesn't matter since I own two of them and two games, Batman Forever and Mortal Kombat.

Yeah. I still love playing Sonic on it. Even if it IS impossible to beat the first few levels due to the poor control reaction, screen ghosting (like the blurring you're talking about, between frames), and the crappy ass music. Bwahahaha.

The problem is that most of those games use glop-tops for the CPU and ROMs to cut down on costs, so they're totally undocumented and undumpable - the best you can do are simulators.

Wrong, the games are sitll there, it's just that some of the X-Board and Y-Board games are unsupported simply because they never were in the first place. Furthermore, the games are emulated in Final Burn Alpha, if I recall correctly. Of course, their being emulated in Final Burn Alpha has no bearing on the MAME rewrite, since the MAME System-16-and-its-variants rewrite is concentrating on accuracy. Also, you still won't see some System-16-and-its-variants games emulated simply because the games are encrypted in a rather powerful way. Basically, the 68000 is encased in an epoxy block with encryption circuitry within as well as some RAM that contains the 65536-bit (you heard me, that's more bits than any encryption scheme on the market at the moment) key and a battery so that the RAM doesn't lose its contents. There is an effort that has been started, however, to find some way of reading the key out of the RAM chip, since the algorithm is already known.

I bet one of those games is Turbo Outrun. wow 65k encryption...I wonder if we can ask Yu Suzuki nicely for the key

Yep. Turbo Outrun, Crackdown, Super Monaco GP, and others use the "Hitachi brick". There's already an ongoing effort to try to read out the key, basically it just involves trying to read the key out of the SRAM chip, the problem is that it's surface-mount and very delicate and old.

I used ot owna CDi and all the Zelda games. Honestly, if you ignored the horrifically bad "video" scenes, they weren't half bad. I kind of wish I could still play them :-/

CDi games had the coolest cases.
