Double Dragon & Kunio-Kun’s menu has multiple filters AND each game gives you four save-state slots instead of just a single one that you get per game for Capcom. Also, look for the “Quality Up” tag in the corner of each game’s over, like seen here. If the game has it, that means most of the flicker and slowdown inherit to NES/Famicom hardware has been removed. BUT, if you insist on having the crappy flicker and slowdown, you can switch to that version of the game. This is a hell of a package.
