Gatsu on the Lantus-X forums has been working on a ZSnes port using SDLx!

"I started trying to get ZSNES to run on the XBOX last night, and due to the SDL port available already for linux I was able to get this going last night with SDLx! :)"

more WIP screenshots are available at this thread here: http://www.lantus-x.com/forum/topic.asp?TOPIC_ID=823
