Boots into games, but runs quite slow with broken graphics and sounds hiccuping.<br/>Long-term MAME Contributor [https://old.reddit.com/r/emulation/comments/12zx5xw/mame_0254/jhwix6z/ "TheMogMiner"'s comment] with 0.254 release about Namco System 23: "In order to more easily debug the rendering pipeline on System 23, I've written (and am continuing to work on) an offline tool called "PIXXIII" - the Packet Inspector for (system) 23. [https://youtu.be/7y6fcdiedc4 Here's an unlisted demo video] of it playing back (and me messing around with) a frame capture from Rapid River. It's already turned up some good results, and has already indicated the potential meaning of an unknown portion of the game's model data, I just haven't had time to dig further into it. With any luck, things should get better reasonably quickly once July rolls around. Hopefully that answers any questions people had about NS23 as it pertains to this release."

===Raw Thrills PC Based - Fast 'n' Furious Arcade, Guitar Hero, Doodle Jump===Doesn't even do anything yet, TeknoParrot boots directly to game unfortunately. ==Bootleg=====Bounty Hunt===

===Sega Master System/Game Gear/Sega System E===- And '''Sega System E''' arcade too.

Pretty SlowDriver Marked as "Imperfect" as of 0.262. it's ARM CPU is fairly demanding to emulate, so you will need a fast PC to run it at Full Speed.

Reverse engineering isn't quite finished on the geometry DSP, so don't expect every game to work. Regardless, Virtua Fighter works and Virtua Racing work fine.

Again, reverse engineering hasn't been finished on the first model's DSP, but there are plenty of other problems that also need to be worked out. Last I checkedAs of 0.262, a reasonable amount of the games work, Virtua Cop 2's textures just display blackbut your mileage will vary on the performance side, since not all of the working games run at full speed. (Moto Raid, Virtua Fighter 2 just freezes after a bit due to bugs in and Rail Chase 2 are the DSP comms.same ones as ElSemi’s attempt)

It's in better shape than [[Sega Model 2]], but it's slow and has lots of bugs. Virtua Fighter 3 either hangs runs at around 50%-60% speed with a few texture glitches (Japan, Revision D) and Emergency Call Ambulance has a similar speed to Virtua Fighter 3, but textures glitches are slightly less frequent. The Lost World: Jurassic Park shows a broken menu displaying "coins" multiple times around the screen and in-game, the game does not actually play, it gets stuck in a sound loop and no models or crashes textures load in after the menu, if a bit into gameplayplayer 2 is brought in it will crash MAME. Dirt Devils boots after a long network check, depending on what set you useand plays at a low fps and it feels like it is played in slow motion.

====Sega Naomi NAOMI Arcade====It's okay, there are just too many bugs. It's also quite slow, as you can expect is expected from most 3D games in MAME. As of MAME 0.262, a few of the games can run, like Crazy Taxi and 18 Wheeler: American Pro Trucker, but not well enough for an accurate or fun experience, but performance may vary on your hardware.

Basically an arcade [[Xbox emulators|Xbox]]variant. It boots OutRun 2, and others but sound is not much elseimplemented in a few of them yet.====LindBergh Lindbergh Arcade====Doesn't even do anything yet, Video has been marked as video"Ok" on many games, audio and IO is yet to be implementedbut sound remains unimplemented on quite a few games.

- Namco System 246/256 arcades (PS2 hardware ISN'T emulated in MAME. Just these two PS2-based Namco System or at least dumps of their games are designed for [https://github.com/mamedev/mame/blob/master/src/mame/namco/namcops2.cpp MAME]. Nothing works yet.). [http://members.iinet.net.au/~lantra9jp1_nbn/gurudumps/system246/index.html Dump list].It shows just a blank background covering the attract mode

Doesn't even do anything yet. It's not a good idea to emulate PC-based arcade hardware itself either. Loading them via compatible layers e.g. [[TeknoParrot]] is a more viable solution, but it boots directly to game unfortunately.
