About

MegaMod is an upgrade PCB board for the Genesis/Megadrive consoles. It started a year ago as a hobby project, but it gradually evolved to 3 versions. It’s main idea is to combine the MegaAmp circuit (created by Ace and Villahed94 members in the sega-16.com forum) for the best crystal clear sound of the console, and a way for switching the region (EUR, US, JP) and video modes (50/60 Hz, PAL/NTSC) with the console Reset button without physically adding flip switches to the console.

Two audio modes can be switched over:

  • Filtered mode – the original VA0 Megadrive Model 1 sound
  • Unfiltered mode – the full audio spectrum of the Genesis hardware

Here’s audio comparison before and after the mod:
