Videohelp.com has a list of player hacks, but your particular player isn't listed there. That was my best shot finding one for you.
You could start a thread in their forum for dvd players: http://forum.videohelp.com/dvd-amp-blu-ray-players-f8.html
But I doubt that will help much. Some players simply don't have hacks available.
It might be simpler to make backup copies of your dvds, which will remove region coding. If you are trying to play PAL dvds on an NTSC player though, this might not be enough. Many players in countries that use NTSC standards don't play PAL dvds.
