Question about the 4 x 2MB sdram
Posted: Sat Nov 23, 2024 7:40 pm
What happens when one or all 4 of them go bad?
The games will still run and get glitched graphics?
I'm asking because:
1. at boot, the dreamcast logo has 2 flickering letters.
2. when I enter the settings menu, the console crashes.
3. It doesn't run any games.
4. gdemu displays the game list, but when i select a game, the console restarts back to gdmenu.
5. the audio has a strong buzz.
This happened after connecting the console to a faulty monitor through vga. That monitor killed 2 consoles. I was able to fix one, but I have no idea where to start on this one...
gdemu, power supply, disc drive, yamaha ic and its ram are tested on another console and are working.
I have dumped the bios and it's identical to v1.01d
