You know, it's a shame, as the first level is actually disporportionately hard, as the difficulty drops for a few levels afterwards, before becoming almost insurmountable. This means that many people get put off before they can really get into the game.
I know all the GnGs were on the Capcom Classics collection for PS2/PSP, but I don't know about the PS1, sorry.
It's a savage game, made all the more savage by the fact that when you have to redo the game with the bracelet, it notches up to the next difficulty level. It's also such a shame, as the insane difficulty means that many people haven't even seen the later stages.
God only knows why you need to complete the game twice - whose idea was that? I need to know so I can hunt him down and kill him slowly...
See I always found this game too hard so never really stuck at it and therefore never got that far into the game. I can honestly say that I have never seen most of the images above in the game
