does valkyrie no densetsu require knowledge of japanese to play?
Yes it does because there are some npcs that ask you questions and you need to get the right answer otherwise you be sent back a bit on that stage.. but you can get round it with trial and error. The real hard bit is killing that last boss which I'm having difficulty with..
Oh I also wanna add:
Gradius
I'll second Salamander (basically next the to the MSX version the pce's has fantastic music not to mention its one of the hardest shmups)
Bomberman '93 (mostly because out of all the bomberman HUcard games imo this has the best BGM's although '94 has the graphics and presentation)
Splatterhouse (japan version since its uncensored)
Devil Crash/crush
Magical Chase
Parasol Stars
Dungeon Explorer
Hana Tahka Dakka!?! (hope i spelt that right)
Bloody Wolf
