| snk6502.c: Adjusted Nibbler board clock rate to use actual known master clock and a logical divisor. [Tafoid] Comment: Still needs 100% verification from actual PCB but this fixes an issue with speed of game and sound effects not matching video output (specifically when snake is first drawn in 3 parts - the sound effect now match the drawing). |
