XGameStation

#1 No.

The console runs on an Sx52 clocked at 80MHz which has to handle all the game logic as well as generating the tv signal. There's no 3d hardware, in fact there's no 2d hardware support aside a little bit to help with the colour burst generation. Also memory wise, you've 262 bytes on chip ram and 256K external SRAM. That's it. Also your actual game/program has to fit within the 4K onboard flash, although with a bit of compression you can fit a good chunk of data in there and uncompress it to SRAM for later use.

The Micro is still a pretty powerful console though, you could probably do simple 3d games with it, perhaps getting as far as a wolfenstein clone if you really new your stuff. Believe me when I say just getting a single pixel to display on a TV is a significant accomplishment though :)

It's still a great little console to play around on though, but equally interesting is Andre's new console the "Hydra". Based around the P8X32A (Propeller) chip. It's an 8 cog (core) chip capable of some pretty impressive stuff. You can squeeze a complete tile engine (albeit with a few restrictions) into one cog, leaving 7 cogs for gameplay logic + audio, or split the tile engine over several cogs to run at a nicer resolution and colour depth.

Although I've not actually got the Hydra, I do have several Propellers and a breadboarded setup that is similar in some regards to the Hydra :)

#2 XGameStation at the moment is more NES/Atari based, but Andre' is now planning 8-bit/16-bit versions of the XGS which might be comparable to more NES/SNES, and like the others don't have 3D acceleration chips, but Andre' said if they get a 32-bit XGS out it probably will have 3D acceleration, but if he can make a cheap enough one that can actually one the TGE might be far from now.
