I sold my VS Duck Hunt chip set to bomber187. The game has worked flawlessly for me in the year+ that I have had it.

I pulled the EPROMS/PPU without any issues packed em up in their little plastic case and sent them to their new home in sunny CA.

When bomber187 got them and installed them on his VS board he said he was just getting a purple screen, he has tried a different board and still had no luck.

I talked to some folks who said he may have a bad CPU so I sent him the one from the VS board that Duck Hunt was installed/working on. Still a no go?

Any ideas? He did mention reversing the EPROMS at one point momentarily. Could this have wiped them? I know with SMB the board needs to be populated with two CPUs, is that the case with Duck Hunt?

At first I would have said a bad cpu... but you gave him a good one. Next I would have said a pcb issue but then you mentioned that he had installed the chips reversed. That probably killed the chips as soon as he powered up.
 
-vs- games the only concern is the PPU, roms are roms :p

but yeah, if he put them in backwards, there toast.
 
Power and ground pins are opposite of each other on EPROMs of that size...

As soon as you power them up backwards they go POOF!
 
You shouldn't be out money because he was a bone head and put the roms in wrong!

Tighe, it's not like that at all. This has been a really smooth transaction. I started this thread to help trouble shoot because I am not that well versed in Nintendo VS. I know they can be quirky.

I just want to see if he wanted new eproms or to send the old ones back for me to test in the old board.

Ok, putting them in wrong and wanting a refund is the same as smashing them with a hammer and wanting a refund.
 
I believe there are a few caps that must be removed in the sea of caps section of the PCB. I don't have the duck hunt manual in front of me so don't go a cutting. :)

Now that you mention it, the board they were on had hacked caps. I will let bomberman know.
