I had a similar experience. My brother had a tg 16 and we had like 5 games for it back in the day, military madness and silent debuggers being my favorite.
About five years ago a friend got this crazy craigslist deal and I ended up with about 80 of the US hucard library and about 2/3 of the cd games in one fell swoop. I quickly realized that this console was criminally underappreciated.
The TG-16/PCE, Mega Drive, and Neo Geo have become my holy trinity of retrogaming. So much fun stuff!
