This is the easiest way I found that lets you emulate the Olympus remote control RM-1 using an old PocketPC:
 * download the trial of "RemoteControl II" at http://www.wincesoft.de/html/remotecontrol_ii.html
 * download the RM-1 theme here http://rs216.rapidshare.com/files/50733665/Olympus_Cam.zip (found [[http://www.remotecentral.com/cgi-bin/mboard/rc-pda/thread.cgi?1151|here]])
 * install everything on the pda. Thats all.

Info: If you don't already have a pda running PocketPC/Windows Mobile it's usually cheaper to buy an RM-1 clone on ebay.
