Thanks for the Castlevania 3 download link, i envy that man Shinya Arino and his awe inspiring patience. I read the Retro Game Master wiki page, it was interesting to read that he gave up on games i assumed where easier than ones he managed to complete!
I had that game and beat the lighting guy once.....got to the "father" boss failed and ended back at the begging of the 6th stage. I then proceeded to smash my NSE with the controller forcing it to reset......I not longer talk of this game. I didn't even know of the final two bosses after that until Youtube. lol
