You don't want a full list, as most of ig is stuff you don't need and would never find.
All you really need to play everything is a PC Engine Duo + Arcade Card Duo + PCE Tap + up to four extra PCE controllers.
Turbo HuCard games aren't worth a separate investment, unless you get a region mod on your system the same time it's receiving other work. Just get a Turbo Everdrive flashcart and try before you buy. There is a torrent out there containing every CD game published bitd, so again, you can try out a game on cdr before buyjng any pricey games.
