I forgot I posted this. In the meantime I found that Virtual Nes runs this game almost perfect.
I came across by a friend sending me this video clip. http://www.youtube.com/watch?v=zYcf2yUgblc
It looked really advanced for the NES and being a sucker for stuff like that I wanted to play it. I noticed that all the different NES emulators I tried didn't run the game properly. There were some sound channels not being emulated and it really did affect game play for me. After some research I found out this game had a special sound chip built into the cartridge. I figured I could just find the game and buy it but turns out there's no NTSC version of it because it was never released in America. I guess the SNES was starting up and developers at the time were shifting their attention to the new system.
Here's some technical data on that sound chip. http://www.x68000.de/soundchips/fme-7/
