I recently added a 60 pin connector from an old famiclone (something like subor without keyboard) to my nes. I used the documentation from the site because it seems that the connector pinout from my famiclone was the same as the famicom one. At first it worked almost perfectly except that the connector pins were a little bit dirty and there were some graphic flaws because of it. I tested it using 4 famiclone cartridges: Aladin 2, Kick Master, 3 eyes boy and Robocop 2. I cleaned the connector with some alcohol and after that when I inserted the cartridge and powered the nes the image started to tremble in some areas. I cleaned the connector using some brush this time and the image started to tremble more than the frist time and the Robocop 2 cartride froze with the title screen (that first sequence which reads "Robocop 2" with blue letters). So i verified the wiring and everything was ok. Then i read on the forum about some 470 ohm resistors connected on the PRG datalines. I connected the resistors and the image got way better but still the robocop 2 cartridge won't run. Then i added some more resistors to the CHR datalines too, and again the image improved and was almost perfect for some games but when playing 3 eyes boy the health bar still trembled a bit. When i inserted the robocop 2 cartridge nothing changed. The game freezes at the title screen. Anyway, what can i do to make ALL the games work normally with no glitches and errors? Can you give me some advices please? Thanks.
