I discovered this port of Ninja Gaiden, thanks to [2463] PCE Ninja Gaiden "game end glitch" by Bernka & Rum in 01:23.73 in the late 2010s. It is way better than the Tecmo's attempt on remaking the NES trilogy on the SNES.
Instead of the boost that the authors did (by pressing 1 and 2 on 1 frame each), I'll take a walk on the 6 stages to play.
