Howdy Ninpo,

Was looking at this game on http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=redhawk&search_id=1 and seems that it is the Korean release version of Stagger 1 http://adb.arcadeitalia.net/dettaglio_mame.php?game_name=stagger1&back_games=redhawk;&search_id=1

Just wanted to let you know if you are looking for some competition / community on this game Stagger 1 is on SRC at https://www.speedrun.com/stagger_i

Not sure if the Red Hawk clone version has any rom differences though, or maybe is a different game in some way and I am not fully understanding.

Take care
