I got mine in the mail about 2 weeks ago and finally got some time to play with it. I have one of the 1st gen 7800 NTSC consoles (with the expansion port--manufactured in 1984). It has the Composite A/V Mod from vintagegamingandmore.com. When I use the Dragonfly cart, TIA sound can barely be heard. However, POKEY and YM2151 are near perfect. When I plug in a 7800 Cart, TIA sound is spot-on. The Dragonfly's firmware is up to date, BTW.
Is there something wrong with my console or Dragonfly? What am I missing? What could I look at? Thanks in advance!
