Title: Dk Jr PCB issues, sprites and sound
Post by: Pinge on April 11, 2017, 11:27:49 AM
I know there is hundreds of threads about DK/DK Jr problems on Klov, I just cant be arsed to look through them so I give you guys a chance to point me in the right direction.

I have recently got a feew issues with my Dk Jr Pcb.

As you can see a few sprites has color issues, Donkey kong are not supposed to have green eyes and teeth (even though it looks kind of cool), and Dk Jrs clothes are also supposed to be white and not green.
Regarding the sound there is a quiet "whirring" sound, like a piece of the jump oe deathsound that never cuts off, it just loops in the background all the time... barely noticeable during gameplay but annoying in attract mode.

where to start? I know fuck-all about pcb-fixing but are eager to learn!

(As a side note I have a Double Donkey kong board on the way home so Im not panicing but would like to have this up and running aswell)

If you listen reaaly, and I mean REALLY REALLY careful when I film close to the speaker you can hear the backgroundfuckedupsoundthing... (or is it only in my head)

And the speaker works normal on other games?

the speaker has no ability to loop a sound like that... but as you can see in the video the speaker is not really a permanent installation... its hooked up with alligator clips  ;D

Look at the memory of the pcb for not correct colors
