After sitting in storage for several years, my previously working Donkey Kong has developed some graphic glitches...
Here a few pictures for everyone to peruse.....
Please notice the graphic glitches just below the score, the head of mario and the read line above donkey kong.....
In an attempt to fix it, I removed all socketed chips, lightly sanded them and re-inserted the chips....some of them were quite dirty so I had high hopes that I resolved the issue but no luck....I checked the ribbons cables and blew out any dust....I read many posts where cleaning the chips solved the glitches so I am thinking the problem lies with perhaps a corrupted prom....
I don't have any reading/burning equipment but would it make sense to simply replace the proms with known good ones? Where would one find good proms? Would a kind KLOV member with a burner and roms be willing to burn new ones and to be compensated accordingly??
Any advice on where to go from here? I did check the website that has images showing the various graphic glitches and their associated chip but did not see my specific glitch unfortunately...
For some reason my images are sideways but hopefully you guys can make out the glitches....
Thanks for any help guys.
Regards,
C.
