METAL SLUG X - "ALL SECRETS" Speed RuN

I played and finished this game on Mame Plus+ with a keyboard on my PC. I "absolutely" did not use any cheats or TAS (tool-assisted speedrun) program. The main achievement here is not finishing the game the fastest and breaking a world record; the main goal is showing you the details overlooked for years, the location of secret prisoners and bonus points by the fastest way.
Thank you very much for your interest and good reviews. See you in the upcoming videos...
