SNES - Game Doctor SF III (Not working)

I recently got a Game Doctor SF III, like this one


And then finally got a matching power supply.

The problem is it does not seem to work.

First off, I know the SNES works 100%. When everything is powered on, and I pop in a floppy, I can hear the motor whine for about a second, then stops. The Floppy drive light does not come on.

When I power on the SNES, the TV detects an input, but all I get is a black screen.

Any one have any experience with these things? I'd love some advice.

Thanks.

 

Make sure you're using a suitable power supply for the GDSF. It must be 9-12V DC center-negative.

Reinsert the GDSF until you see a menu.

Hold R when powering on to skip auto-load.

Your games must be in MGD (header-free) or GDSF format.

 

Thanks for the reply, I'm pretty sure my power supply is ok. I've added a photo to have someone double check.



Not sure what you mean by the 2nd and 4th suggestions.

Reinsert the GDSF until you see a menu. (Do you literally mean reseating the GDSF?)

Your games must be in MGD (header-free) or GDSF format. (This one you lost me completely.)

 

Update.

So, I can get it to boot, but I have to have GDSF connected, no gamepack on top, hold R, then Power on the device.

Black Screen

THEN! I have to insert a gamepack into the top slot, 3-5 times, then suddenly. BLAM! it works.

This can't be how I have to use it on a normal basis.

Update 2

This trick seems to work half of the time with Super Mario World, but if I put in my EarthBound game, this trick does not seem to work at all.

 

GDSF will always start into a menu if it's making a good connection, that's all I meant, so yes reseat it until the connection is OK.

You don't need to have a game inserted to use the GDSFIII. Are you using a PAL or region-modded SNES? Most backup units come with NTSC lockout chips installed, so you might need to swap it.

If you don't know how to convert ROM images, you can at least backup some original games (first to the unit's DRAM, then to disk).

 

I have an NTSC console, though I'm not sure which region the GDSF is. Any idea how I can tell?

When I had the unit booted, I was able to format the floppy, dump my SMW onto the floppy, then play SMW from the floppy, and remove the SMW cart.

The fact that I got the thing to boot at all, leads me to believe that it is an NTSC version. I'm going to test another SNES that I know is NTSC, and I know has not had a lockout chip disabled.

Ok, after the same sort of finky behaviour, I was also able to get the GDSF to boot on my SNES Mini.
