Gamemagic is not opensource, so that one is out of the realm of possibility.
All of those games are Java also, and unless Java is ported to the xbox(eww!) then don't expect too much.
FYI Gamemagic is not needed to play those games on a pc as far as I understand. From another forum:
Many people have asked, "can i play java (j2me) games on my computer?"
the answer is..."YES"
This is how you do it:
First of all, you will need Java 2 Platform, Standard Edition, v 1.4.2 (J2SE)
you will find mirrors to the download here:
http://java.sun.com/j2se/1.4.2/download.htmlNext, you will need to get the software that lets you play the j2me apps (the mobile java apps) J2ME Wireless Toolkit 2.1
you will need to register to download here:
http://sdlcweb2c.sun.com/ECom/EComAc...MLoadBalanced=takes about 2 minutes, pretty simple
now when u install that, it will ask you where the virtual machine is, if u installed the previous software by default settings, it should be here:
C:\Sun\AppServer\jdk
now, you are almost good to go
now to run the game, u will need to run the *.jad file, u cant run the *.jar file
to make the *.jad file if you dont have it already, download this software
http://www.subfuture.com/nokia/jadgen.ziphere is an example of what youd type in:
if you saved a game called "game.jar" to the C drive, you will type in:
C:\game.jar
now you can play the *.jad file in the software called "Run MIDP Application ..." in the folder called "J2ME Wireless Toolkit 2.0_01"
So its likely possible to play them via linux on the xbox. Java is certainly available for just about every OS.
But don't hold your breath for any native java .xbe's, thats a project thats far too complicated to delve into...
