Donkey Kong 3 Glitchy & Broken - Part 2 [FIXED]
47WE MADE PROGRESS! DK3 is fixed! Big thanks to those who helped. I'm not going to lie, access to other boards helps! I was able to swap ROMs and try out a high score saves/free play kit which eliminates ROMS. By doing that we were able to determine that it was a bad ROM before I had an EPROM programmer. Thanks go out to Jay at FreeplayRI, NEMike and Rob.
Here's the TL;DR version: a program ROM was bad and 6H for sound was bad. NEMike sent me a burned ROM for 6H to fix the sound issue. Jay from Freeplay RI when I was down helping out allowed me to test my board in his DK3 and use his HSS kit to 'verify ROMs'. That essentially eliminated my ROMs and narrowed it down to that area. One/Two of the four ROMs in that area were bad. I purchased a HSS Kit for DK3 from www.highscoresaves.com and that fixed the issue without having to burn new ROMs or replace sockets.
