Help! Dreamcast Bricked! :(

[Pedro_Oliveira]

I installed the bios v0.74_beta.bios, left my Dreamcast make all the battery of tests, out of curiosity, and now my Dreamcast is the original bios with black logo and no longer carries any game. What to do?

---

In secondary Bios, it is this battery of tests, but when I switch the key to the original bios SEGA MPR he gets the logo in black and white and does not work any game disc much less the Dreamshell I killed my own ... original bios? If so, I'll be transplanting another Dreamcast junk that I have here and will replace the damaged bios.

More pictures of my Dreamcast.
Notice that I changed the key to the original bios and is thus far without running any kind of game! Putz! I'm very upset with this shit! = \


At the end of the loading screen CD player but does not run a disk or to any song! Much less games!
