That was an April Fool's joke, I think. (Though it may not be too implausible, if one can squeeze that out of the unit's 12MHz CPU.)
Apparently version 2.3 of the firmware is slated to have plug-in modules, allowing third-party programs/games/utilities to be added to it without recompiling the whole thing.
Works like a charm. Thanks for the tip. My Archos was lame, now it walks. The Tetris is very old skool.
But are you playing Doom on it?
