The Neo Geo AES is fully region free. Basically all versions of the game is contained on a home AES cart including the arcade code.
All Neo CD pads and AV Cables work with the AES too. The pads are really good too, the d pad works much like an arcade stick, though the old-style Neo stick IS the best way to play these games. Still, I often use the pad instead.
If you have the money the AES is the one to get.
All I care about is RGB
Excellent (clasps hands together like Mr Burns), so do I.
Unfortunitely this varies drastically according which batch of machine you end up with. Later serial number machines have the worst RGB output as SNK tried to improve the system' s dire composite out. late Neo Geo consoles RGB output has faint horizontal lines, and a mesh like grid over the picture, washing out the colours and weaking the sharpness of the picture.
Try to get one with as early serial number you can, though these can go for higher prices, especially if you are buying from someone in the know. The only real downside with earlier machines RGB out, is that it is a little dark.
Failing that you can get a pure RGB mod done to your AES which will take the video directly from the video processor rather than the AV out chip. Most people will also do a pure stereo mod for the system which works in the same way.
In terms of games the Jap versions are much cheaper to buy than their US/English counterparts, and with later games you can usually change the language in the options screen. Sadly earlier ones like the first Samurai Showdown do not have this option.
Sorry if my response feels a little rushed, thinking about everything at once.
If you need any other info, feel free to ask.
