Help please! My dreamcast is restarting itself when I m trying to load xdp browser and few games

Post#1 » Fri Feb 07, 2020 11:33 am

Hi everyone. I m new here,
First of all I want to say sorry for my english...
I bought a dreamcast 2 months ago with a dreampi because I wanted to play online. All the games worked fine but Sonic 3d, xdp browser and Dreamkey doesnt work, my dreamcast restart itself while booting from cd and sd with dreamshell, but no results.. quake 3 arena works fine in single player, but after I make internet configurations and press dial it does the same thing, is restarting....
I also cleaned the contact pins like all the tutorials said about that random restart, but mine is not restarting random, only before I want to load certain games and browsers...
I m verry dissapointed:(
I would appreciate any help :roll:

Other than cleaning each of the pins of the PSU not sure what else to try. You need to clean of the oxydisation on the PSU pins of the motherboard better most likely. just take some sandpaper to the face of each pin itself on the motherboard after removing the PSU. Sand each face of every pin, blow out the dust and reasymble. Try it out and see if that makes it run any better.

Other than this I suggest looking into the Pico PSI mods for DC.

Your GD-ROM reader needs maintenance. If you have a serial sd card with dreamshell start Quke 3 Arena it will not reset.

Make a video, it may be the defective fan controller chip.

First I cleaned normaly with alcohol, then I soldered the pins like in tutorial. I dont know what is the Pico Psi mods.
All the games work perfect except quake multiplayer, sonic and all the browsers I tried:(

It is the defective fan chip on your VA2 board.
