Underground Mission / 地道戰 (Shanghai Paradise 1997) Full Game

A playthrough of Shanghai Paradise's 1997 puzzle platformer. If you're wondering why the player character sometimes stops and then starts no-clipping through the walls in the later levels, that's me doing some hex editing off-screen, as the game is unfortunately impossible to beat without it due to some glaring design oversights. Also, with most SP games, this is the Power Joy re-release, as the original version is once again lost media. After beating the game and showing the ending, the game loops back to the first level, so I use this as an opportunity to showcase the Game Over screen.

Judging from the Chinese name of this game shown on the intermission screen, I believe this is a fangame of the 1965 film of the same name. Assuming that's the case, that would mean you're playing as a Chinese soldier fighting off Imperial Japanese forces during World War II. You're tasked with infiltrating various Japanese tunnel systems to collect various items and rescue the captured prisoner trapped behind a wall.

The game would actually be really fun if it wasn't held together by toothpicks and bubblegum. There's a stupendous amount of things that trigger a game crash, such as collecting a medpack when you're at full health or attempting to blow up a spike using a grenade. Aside from that, the scoring on the intermission screen is still in hexadecimal, hence why the numbers seem to glitch out, as there's no proper characters for A-F. This all pales in comparison to this game's biggest flaw: Starting on Stage 10, some of the items needed to progress are inexplicably stuck in the walls, making the game impossible to beat on real hardware, and can only be beaten on emulators if you know how hex editing works. If you do manage to clear Stage 10, the levels start to deteriorate more and more as you progress, with the stage numbers glitching out, random blue chunks being scattered throughout the tunnels, and the wall tiles not disappearing after being destroyed.

I wonder if this game was cut down like Waixing's release of F-22 in order to fit onto the multicart easier and the SP version has more content and better coding. There is some evidence in the ROM that suggests that, but it might just be wishful thinking. Also, before you say it, the houses on the Game Over screen are indeed taken from Friday the 13th.
