Hi, I have a PAL Dreamcast with the link83/bios-mod. Today, I got tired of the PAL50hz mode that it defaults to in some games, so I decided to do the region mod aswell (changing video-output to PAL60..). Soldiered R512 to +12V, and bridged the R422. Assembled everything together, and pressed the power-button. So here comes the fu#%d up part: There's NO startup animation or sound at all, and after about 5 seconds, the Dreamcast-logo is displayed, but it just stays there for about 2minutes and then the bios-menu appears. The drive spins when I insert a game, but there is no "please wait while disc is being checked". It's like it doesnt know wether the lid is open or closed, but I hear the gd-rom working when I insert a game. Here's a video: http://www.youtube.com/watch?v=PFNtFRNq6Vs Tried disconnecting the r512 and 12v wires, but to no success. Have I fried my motherboard with this mod or what's wrong? I also accidentally cut one of the three tiny wires that goes from the controller-board to the fan, but soldiered it up afterwards. The fan is working, so it shouldn't be that, right? As the red wire should be the +5v? Thanks.
Edit:Oh well that's what I get for not reading things properly ... Sorry -_-; The Dreamcast does that (no boot logo animation, sit on boot logo for a while) when it cannot communicate with the GD-ROM assembly. Check if there were damage anywhere around the GD-ROM assy. And finally, you should change video mode to NTSC with the region change disc if you want it to default to 60hz. NOT mod the hardware. -_-;
In order to run and save the settings from the region mod, you have to solder a wire from r512 to +12V. But anyway, its solved now, and yes, it had to do with the GD-ROM. I have spliced to wires with a (dunno what you call it in english) thing that lets you "splice" 2 wires, and it made it too tight for the gd-rom to connect to its connector, but gave it power so it would spin, but not send the info to the mobo. But thanks for your reply tho!
