Sega Naomi games working in MAME?

[arcadecab]

I have not updated my mame set for awhile, but I noticed that several Sega Naomi games were added to the rom list around 0.114 or 0.115.  They seemed to be listed as preliminary, but just wondering if these games, in particular, Virtua NBA are at all playable using the latest version of MAME?  If not, how long until you think these games will be playable with MAME?  What size processor will be needed to run them at full speed?
Thanks.

No
7 years (plus or minus one order of magnitude)
C4D @ 1 THz

Okay, maybe the last one is a little bit of an exaggeration , but the Naomi had a 32 bit RISC CPU running @ 200 MHz, a tile based video chip @ 100 MHz (no current PC GPUs do it this way), and a sound system that used a RISC CPU @ 45 MHz.  Even if you use the very bad estimate of needing 20x to emulate, that's almost 7 GHz just for these three parts.

Actually wasnt there a tile based PC video card a few years back? Completely bombed of course. Name escapes me.

Was it the Videologic VividXS Kyro 2?

Since the Naomi was Dreamcast based and Dreamcast emulation is coming along so nicely these days, do you really think it will take that long???

Kyro! Thats the name. Thanks Red. That would have bugged me.

That being the case, why not use a Dreamcast emulator like NullDC to play them? NullDC works rather well in a cabinet too and with AtomicFE or some fiddling with MaLa you can get the games to appear all in one list so it's seamless. Playing Ikaruga and Power Stone 2 on the cab is a blast

There is always that.

Yes, dreamcast emulation is a way to play the ports that occurred from arcade games.  However, not every Naomi game was ported to the dreamcast.  The point is that for those with MAME cabinets, it is a great convenience to have MAME emulate the Naomi games directly and further expanding the gaming experience for MAME emulation.
My question is; if it is sooo far away, why would MAME emulators even bother with adding it to the rom list and getting us excited about future capacity if it is "years" away from any functionality?  With the speed and efficency of processors getting better all the time, is it so far fetched that a high-performance PC could run a game on a system that is 8 years old using MAME?  It doesn't seem that far fetched, but maybe it is just me.  What has been the track history on this:  When a game is listed in the rom set, how long until it is "playable"?  If I remember correctly, some CHD games have taken some time to gain enough speed to run, but not that long.  Right?
Thanks.

The thing with mame is, they are trying to preserve the technology and have it properly emulated, being playable is a whole other matter.  Take zinc for instance, those games are pretty much all in mame, but Zinc uses 3D acceleration and some hacks to make the games playable, the mame team is only concerned with correct and proper hardware emulation, so no #D accel or hacks are used to make the games work properly.  And if you consider Blitz and Gauntlet from midway in MAME, the emulation is pretty good but the speed sucks.  In a stand alone emulator with the proper tweaks they would probably play just fine.

Common misconception, but ZiNc actually doesn't use any "hacks".  Just the good old fashioned combo of a dynamic recompiler and hardware rendering.

Naomi will be comin' round the mountain when she comes.  We gotta finish Model 2 first.

When will we see a Zinc update?  Hopefully soon.

I need to look into this...   would I need an analog joystick to play though?
