Double Dragon - video and audio problem

I want to thank everyone for their help, at this point my health is stopping me from doing any more on this board but as nauseous is interested at looking at the data on the ROMs, I'll be sending the board on for him to check them out.

 

Sincerely,

Glenn

I'd like to give everyone who was interested in this thread, a positive update about this DD PCB. To recap, these boards had a number of problems with both the graphics and sound but sadly it got beyond my current abilities (and I didn't own an EPROM reader/writer), nauseous offered to "check my boards out" for me in exchange for retrieving the data from a couple of my EPROMS to replace the corrupted data on his EPROMs.

 

Well... I have recieved the boards back from nauseous and the boards are FIXED and he cleaned them up and they look and work as good as new. Mate... you are a LEGEND!! :ty :023:

 

Here is a run-down of what nauseous fixed:

 

Replaced all of the capacitors (this stopped the board from resetting over and over),

Replaced ROM #5 (I am told this is the boot code for the CPU which gave blue blocks on the screen at start-up),

he also mentions that among a few other small tweaks, he fixed a glitch in the sprites by fixing a bad solder joint on the EL1200 custom.

 

A BIG THANK YOU to nauseous and to all the other people who helped me muddle through the initial testing, you are an AWESOME bunch!!

 

Cheers,

Glenn

Always good to see someone getting help and a positive result on here this is what the forum is all about :D
