Ghouls n ghosts best port is most likely the X68000 version. But the MD version is spot on gameplay wise. You can practice on the MD version and play just the same on the PCB. Haven't spent any time on the supergrafx version but I don't like the way it sounds or looks.
I'm a big fan of the Supergrafx version. I personally like it better than the Genesis version.
If I'm remembering right the biggest problem with the SuperGrafx version is that it limits you to 5 continues total. Which makes it a bit of a nightmare to play through the whole game.
Supergrafx version is 8 megabit which is slightly bigger than the genesis/MD conversion at 5 megabit... but the sound on supergrapfx is just bad... compared to the genny. But the supergrafx has more animations and a lot more background detail that is missing in the genny version. But yes, x68k version is hands down probably the best conversion... the midi music is phenomenal.
You can always go into the hidden menu & change lives, difficulty & points for extra lives
also it looks like if you use the following code on the one player only push run button screen you can give yourself yourself extra credits. up up down down left right left right 1 2. For a max of 9 credits.
super ghouls and ghosts is not even close to the same game
That's because Super Ghouls'n Ghosts is a sequel to Ghouls'n Ghosts - third in the series, I think.
