Castlevania Chronicles PS1 (JP/JP-PSN version)
Some additional points like the bats in block 8-2 and Medusa Boss invulnerable glitch fix in western versions are actually a painful experience for me, but I eventually get through Original mode for 10+ loops in Western version and 40+ loops in JP version
The game just has so much magic power that attracted me, made it THE all-time favorite for me in a long time, until I acknowledged the presence of Rosenkreuzstilette series
When it announced to be available in JP PS STORE last year, I was so happy that I screamed for 5 minutes. Then there are DIFFERENCE in JP PSN version that make my lone journey worthy. I'm so happy that they fixed most of the glitches, but in dark-side, damn! The Medusa Boss invincibility also fixed thus make a more difficult battle than I remembered earlier, but for overall experience I really enjoyed the game, for my past, for now and forever.
EDIT: Found my progress, it has issues loading with Psxjin emulator (I played mainly on the PSP with custom ROM) and I can't remember the exact number how many loops I get through in the past 3 years
