|
|
hi there ^^
i can't help myself anymore :>
i have a question about my doctor v64 which isn't working as it should be.
when i load a rom and start the n64 nothing happens
the screen stays blue (my tv stays blue if no signal is there)
exept for a crazy nations bootloader
boot.v64 http://ul.to/87a7kja6
the file is very tiny about 250kb
that rom is fine, there is a picture and sound
the first thing i tested was the black connector (v64<->n64)
i tested the circuit from the v64 mainboard through the n64 up to the
bung boot adapter -> everything is fine with the connection
my next step was testing the ram:
the internal check says all is ok
than i uploaded a rom into dram und downloaded it with my pc again
and compared the files -> everything fine, too
if i put a cart directly in my v64 and upload it to my pc the rom
dumps well nothing special
even if i dump super mario world 64 (pal) und try to run that rom
nothing happens.
as far as i know sm64 has no copy protection and i should have no cic problem in that case
----
things i have and could use to test something
- super mario kart (pal)
- super mario world (pal)
- dk64 und some motocross game
- Doctor v64 128Mb (the second 128Mbit ram is broken maybe a hint? some of the little brown smd Capacitor are blown up)
on the Doctor v64 mainboard come Caps lost their plastic sourrounding
mybe some of them are broken?
- N64 pal and a N64 ntsc (but no ntsc tv :> so only sound is testable)
my question now is, why is only one bootloader working and nothing else?
ah before i forget to mention it, lac's bootloader is loading too but only with a black screen
i would be very happy if anyone have a hint for me ^^ |

Have you tried using only the 128m ram module that doesn't have broken caps? |
