I too have the D2Sun on my PAL console. Ive had no problems what so ever with playing PAL backups and 9 times out of 10 ill get NTSC backups to work too. Yesterday i installed starfall (with alot of help and big thanks to wiihacks) and downgraded my firmware as i was on 3.4. Starfall works a treat as i no longer get asked to update and i can happily go on playing my collection of backups
so does this starfall downgrade your firmware? im on pal 3.4 with a d2sun chip and use brickblocker on every game regardless of region. I want to save the hassle of using brickblocker cause this starfall looks interesting and will save me messing with BB?
