There are two 'Felix the Cat' games released for Famicom/NES: an official one by Hudson Soft (released in 1992) and an unlicensed one by a Chinese company named Dragon Co., with a 1998 copyright date.
This movie was done using the unlicensed version, which by the way was the base for lots of hacked versions on some Famiclones and plug-n-plays released in mainland China, also for 'The Hacker (NJ049)' by Shenzhen Nanjing Technology.
Completing this game the normal way takes around 17-18 minutes, but apparently there is an alternate way to do this in less than 8 minutes, which is the main purpose of this movie.
Game objectives
- Emulator used: FCEUX 2.2.3
- Main objective here is to show an alternate way to complete all levels in the unlicensed version of Felix the Cat, especially in levels 1 and 7 where you normally have to beat the boss in order to finish them. This method implies exploiting a glitch where if the player is close to go off-screen to the right, it'll autofinish the level.
Comments
How the 'glitch' method was used in the movie: basically the player requires timed jumps while moving forward, plus using the attack button while jumping in most cases. As long as it is done properly (by avoiding walls where possible), it'll place the player at a farther distance than the normal centered position, slowly reaching the right border of the screen.
Other comments
Sadly the glitch cannot be done at the 4th level (underwater) because of the high amount of walls and enemies covering some narrow paths there. Damage was intentionally taken to save time by completing the level with Felix's initial form.
NOTE: Do not confuse this version with the official Hudson Soft one. While both are based on 'Felix the Cat' cartoon, both versions are completely different each other.
Maru: Judging.
