On the XBox, some commercial games could run third party fan-made mods (provided the XBox was modded), which was amazing. I remember games such as Morrowind, the Grand Theft Auto games, Star Was Battlefront 2, etc, supporting this. The big limitation was memory, of course, as the XBox only had 64 MB of RAM (which was also used for video RAM), but I have had my XBox upgraded to 128 MB, so I was wondering in anyone had released a patch for any of these games to allow the game to access more than 64 MB of RAM, and so allow more mods to be used with applicable games.
Also, or course, fan-ported games such as Duke Nukem 3D (using 'XDuke'), Shadow Warrior (using 'ShadowX), Doom 1 and 2 (using 'Doom-X'), and I think ports of Quake 1 and 2, etc (I don't like the Quake games, so I can't speak from experience), can use third party mods, and with these ports being written specifically for the XBox, then they would see more likely to maybe receive 128 MB support upgrades. Have any of these ports been upgraded, to allow for the support of more demanding mods.
