Anybody interested in porting, i don't have the source but its out there, its a set of old DOS games but before you flamers start i have tried DOSXBOX and they aren't playable with that . Anybody out there, these are great games.

According to http://forums.xbox-scene.com/index.php?showtopic=313261 they are all working perfectly with DosXbox except for a sound issue with #6.

Not to mention the official Commander Keen source code is not available. If you're talking about a clone that's open source, please provide the link.

its playable in dosxbox

i have tried every one of them, the first one doesn't support joystick, and its the only one that has sound the rest dont, only number 5 has sound and supports joystick but it needs at least 3 buttons and dosbox only supports 2 buttons and is way to hard configure

All of them work, with excellent sound, music and controls, i guarantee you that because I've played them quite some time on my xbox. Perhaps you're using an old version of dosxbox?
