hints and tips please, stuck playing Waixing games.

[prince tomato]

hi,
some of you are probably wondering why i even bother playing the Waixing Famicom games,
well, i have them, and i quite like some of them.
but because i can't understand Chinese some parts are quite hard.

Pi Nuo Cao De Fu Su:
i've been in every part of the overworld, spotted a locked chest,
some golden crest type thing,
and a rock with Chinese characters on it (?),
i probably need one or all of these but i can't figure out how to interact with them, pick them up or whatever.
also, the sumo guy with the diaper that is by the bridge won't let me pass.

Heal The Century:
(the game that looks like Beyond Oasis)
i'm running around in my parachute pants, going in and out of every building in the first screen,
trying to talk to folks, but i just can't get out of there.
i wanna get to the fighting part!

Hero on Devil Lands,
i've been to the place with the practice battle, visited the shops, but i can't leave the first village and cross the desert or anything.

Tunnel Warfare:
(Di Dao Zhan)
i leave the village,
spot the incoming Japanese soldiers,
and stand my ground, shooting them left and right,
but it is a survival type thing where waves of soldiers keep coming until i'm out of ammo and die.
where do i go when the soldiers come?


Zelda, Link to the past,
i think i need a complete walkthrough for this one...

Diablo II ,Nanjing:
i got my gear equiped,
got up to a solid level 8 after 3 hours of grinding,
can't beat first boss on the cemetary, Andariel?
he does more damage as i level up, it just ain't happening.
what's up with the tree?
no scrolls or town portals?
no waypoints?
where do i buy weapons?

surely some of you have tried to play these before,
so, any hints or tips are more than welcome.
