Timeline of events: ACE9921 & Villahed94 developed the original Mega Amp 1.0. Inception for a mod board that combines the Mega Amp with an RGB video amplifier was Bob from RetroRGB's idea. Rene from db Electronics designed the first build. Tienfeng designed the second with a modified version of the then new Mega Amp 2.0, on which Jose Cruz helped with testing. That became the Triple Bypass v2.
