Re-visited Castlevania The Adventure Rebirth hard mode with better dolphin emulator (powered-up 5.0 version with 64-bit OS support) in my laptop and it sucks as always. The frame rates still drop at the "crushing wall" traps in stage 3 and I had no idea. The Grim Reaper was fairly tough, not to mention the whole damned stage 5 in hard mode, but he's cool. Also the laser attack reminds me Grolla/Raimund's super Desperation move in Rosenkreuzstilette Freudenstachel and the super Desperation move of Masked Demon/Death in Castlevania The Lecarde Chronicles.
Stage 4 succubus route in hard mode was living hell, so I chosed to get two keys to open the alternate path. The Golem boss must be defeated with one life from the checkpoint after alternate path entrance or you'll get sucked (The time players were given was too short if players die at boss fight and continue with next life)
Dracula was also tough to hell, but I love Adventure Rebirth
Played Castlevania The Adventure and Belmont's Revenge with emulators. The music was great, the games were too tough to beat that I must set emulator's save states during boss fights, but I was very satisfied for the amazing quality that they gave players at that time.
Also involved in PC versions of King of Fighters 98 UM and 2002 UM because I can use boss characters to kick some stuff, unlike original versions
