Almost all of the graphics from the original game are replaced, plus the intro and ending text. Bizarrely, the intro text appears to be replaced with a poorly translated version of My Heart Will Go On by Céline Dion. Aside from the title screen, the game's use of color is limited, which gives it the appearance of a Super Game Boy game. Possibly due to the colorization process, the game suffers from extreme slowdown, running consistently at about half speed in most emulators.
Pokemon Action Chapter Edit
Kǒudài Guàishòu Dòngzuò Piān (口袋怪獸 動作篇, lit. Pokemon Action Chapter) is a hack of the colorized Smurfs Nightmare release. Unlike Monster Go Go Go, most of the graphics are unchanged; it only replaces the title screen and Pikachu sprite, as well as other miscellaneous graphics.
This version is not to be confused with The Pikachu Nightmare which is an entirely separate hack, possibly homebrew in origin, with a completely different Pikachu sprite and an only slightly modified title screen. The sprites and title screen in Action Chapter are the same as in Go Go Go.
A second Monster Go! Go! Go!! game is known to exist, and it appears to be a hack of Kirby's Dream Land 2. However, it is much rarer than the first and is currently undumped.
