So my Dreamcast died when I was about an hour away from finishing the second scenario of Resident Evil 2 (Leon B)... RIP.
I'll upload a video later, but I'm thinking it's a problem with the PSU: every time a disc tries to read, the system shuts down completely. It'll turn back on, and will even boot the OS if there's no disc inside. The CD tray spindle will move, and the laser will try to focus if there's no disc in there, but again, as soon as a disc is inserted and the laser tries to actually read it, POWER OFF.
I did reseat the PSU, and all the pins are aligned correctly. I also tried with a different power cord (with the same result).
Anyone have this issue before? I'd love to finish RE2 without having to replay both campaigns, haha. Even though I was planning on playing RE3 on Dreamcast, I think I'll switch to Gamecube for that playthrough regardless, haha.
