gdemu flashing led with or without sd card

[suntftl]

as of recently my gdemu has decided it no longer wants to work as intended. games will randomly crash or become super slow, or it'll just become a black screen.

the red led flashes like crazy regardless of if an sd card is inserted. every sound is super low pitched, and no matter what i do (re-inserting card, power cycling) nothing fixes it anymore. i'm a bit hesitant to open up the system because something tells me i'll end up ruining everything.

what could be the issue here, though? i'm honestly not sure if i have a clone or an official gdemu, but just a few days ago it was perfectly fine. should i just get a new gdemu or what?

here's a video showcasing what happens with the led and what happens if the system manages to boot: https://www.youtube.com/watch?v=OefmLGxiXkg

I had the exact same thing recently, for me it was the psu.

was sent a video about it in another thread and sure enough that was the issue. turns out taking apart and putting back together a dreamcast isn't all that hard lol
