Didn't know if anyone is interested in this but the xlink kai engine seems to run fine on the wl500g.
For those puzzled about what kai actually is wonder over to http://www.teamxlink.co.uk/
I recommend you try the WinXP client/server before attempting this, and you will need to register your xtag.
Seemed quite simple to get running, I copied over the files to my usb hdd, entered the directory and ranI already have kaid installed and the win xp install includes the java client, just run the kai config tool, and select the options listed in the screen shot below.Code:./kaid
Then select from your start menu; start kai, when the java ui pops up select file --> settings
Enter your router ip as the engine address, and the port (usually 34522), as well as your xtag details
Then you can hit attach engine and login to see the arena, please note I have not tested this with a console yet as it is in bits at the moment! :-)
