For me, the music is fantastic in Dynastic Hero, I actually tend to model some of my songs in the same vein as the music done for it, not to mention the Ys series & Dungeon Explorer 2, among others.  
BTW, speaking of Wonderboy.  Of all things, I decided to look to see what games are available for my cell phone, primarily looking for Double Dragon, well, I find that, but, I also notice a game called Super Adventure Island.  Well, I figured it was a choppy version of the SNES game, so I download it, & what does it turn out to be?  I know, you're thinking it's just Wonderboy aka Hudson's Adventure Island..........wrong, it's Wonderboy in Monsterland, with Master Higgins!  The levels are pretty much untouched, as are the enemies.  The bosses, well, I made it to the first one, is totally different.  As are the characters in the houses, & ofcoarse, you're Master Higgins.  Plus, instead of a sword, that you slash, you throw an axe that fly's back at you!  How awesome is that?  Anyways, it has armor & shields & boots just like Wonderboy, but, I haven't been able to afford them yet.  I'll have to play it again, & save my money.  It seems like atleast some of the hidden coins are still in the levels.  But not all.......not that I remember every place where they are hidden.
