NTSC and PAL Mattel versions of the NES have a different processor among other differences, but are the same pins used for overclocking the processor?
According to Nesdev wiki in reference to the processor;
" 1.789773Mhz for NTSC (System 21.47727Mhz / 12) and 26.60 MHz ÷ 16 = 1.662607 MHz for PAL
Now i have bought a 28 MHZ crystal oscillator expecting 28 / 12 = 2.3 MHZ but now realise ill only get 1.75Mhz. Therefore meaning ill need a ~36.8MHZ crystal oscillator to overclock the processor to 2.3Mhz
But from all of the information I could find relating to this subject its not that simple, ive read about the 60hz/50hz changes, other differences and pieces of information almost entirely abbreviated that have all but left me confused and lost... i'm a truck mechanic.. i can understand only simple electronics.
This is where YOU come in, how and how much do i overclock my PAL Mattel version of the NES?
Note: my machine has already got a (stupid) blue light and the lockout chip no.4 pin removed. So im not butchering an original unmolested machine. Don't tell me "don't do it" or "buy an NTSC machine"
