Sega Saturn problems

Post by Masen »

Hi,

as you can read here : http://www.dcemulation.com/phpBB/viewtopic.php?t=84601

i bought a (maybe) defect sega saturn on ebay.
it is a us/ntsc one and it came without any cables and joypads.
but as the power cables are the standart ones i can say that the saturn runs and the discdrive is spinning too.

The main problem is that the AV out port looks very damaged, im not sure that a cable will completly fit and work with it. So i wanted to know if there is another possibillity , like the VGA mod on Dreamcast or something ?

And are there any good repair/mod pages for Saturn ? (yeah i tried google but ive only found commercial repair and mod-chip services)


thx

well you can probably solder wires on the av port pins to build a new one. You just need this port pinout : http://www.gamesx.com/avpinouts/saturnav.htm.
You could for example make a db9 adapter, fit a female db9 in the saturn case and make an av cable with just a db9 and a standard cinch av cable (I did something like that for my genesis, but used a mini din).

yeah thank you ^^
but can you explain it in more detail, or do you have any links to tutorials or something for making own ports/cables ?

well it should be quite easy, say you want to make a composite video/stereo audio cable.
cut the end of a composite video cable, you'll get an insulated wire and a shield wire.
solder the shield to gnd, and the cable to comp video on the saturn pcb.
do the same for the audio cable, solder the shields to gnd and the other cables to left/right.

If you want to use a db9 just do the same choose a pinout and make sure it corresponds on the male and it's female counterpart.

here's a nice picture :

if you want to use a db9 just solder the cables to the db9 pins and case. Do the same inside the saturn.

The colors are correct (just remember: red = right).

1. i re-assembled the saturn, put it togheter again , everthings fine ...
2. i re-assembled the saturn, put it togheter again, Power LED not working Access LED is on but not blinking as usual.
3. i re-assembled the saturn, played with this connection wire-thing connecting this LED/Controller PCB to the main board, Power LED is working again but Access LED dont ...
