Hello, gang. I came here hoping to run this issue past the experts.
A few years ago I bought a used Turbo setup consisting of the original US base unit, a turbo booster, and the white Turbo CD unit, plus cables etc. It was refurbished but looked to have been well cared-for, and it worked well for me for awhile. I bought a new Japanese System Card 3.0 via ebay, and a HuCard converter new from Telegames. These also worked well, but after a few months the Turbo stopped recognizing the System Card 3.0. So I bought a used Arcade Pro system card from a very reputable local shop. This also worked well for me for awhile, but yesterday my Turbo stopped recognizing my Arcade Pro card.
Could my converter unit be frying my system cards somehow? I can't seem to find any similar stories online. I'm still rather new to the TurboGrafx, and with all the goofy system card requirements and other quirks, I'm not sure if I'm doing something wrong. Is this a common issue? And is it safe to assume my system cards are done for? I've attached some photos of my setup below.
Please let me know your thoughts.
(EDIT: ...and my photos aren't showing up. Sorry.)
