Donkey Kong Jr Graphics Glitches - Help needed
« on: December 11, 2014, 11:26:51 AM »
Hi All,

My DKJR had graphics glitches from the start, now is the time to get fixing it.

If any of you know why I have a blue Mario, and why Kong looks odd, please post me some pointers.

I've already reseated every chip I can, I went from vanishing sprites to blue mario...so it's an improvement, at lease ti can play it now, but it's not right..

I know next steps are voltages, and to be honest the power supply in there is so rusty it might just be a no brainer and I should just rip that sucker out, but I thought I'd post this anyway, you just might know this board and can say hey it's 3E from just seeing a vid.

Enjoy.
