|Console||Game Boy Advance|
Sonic 3: Fighter Sonic (also known as Fighter Sonic) is a pirate game for the Game Boy Advance.
It uses music from Vast Fame though it is believed to have been developed and published by Sintax since it shares an engine with several of their other GBA games such as Digimon Adventure and Crash Advance IV.
As stated, this game uses the same engine as a string of other GBA platform games likely made by Sintax. You can move left, right, and jump. Here, your projectile attack is throwing "spin dashes" at the opponent. This engine suffers from a number of bugs, particularly with the audio.
Most if not all of the sprites in this game are ripped from Sonic Advance and its sequels. Notably, Sonic's life icon is his Sonic Advance life icon except it has sunglasses. Sintax also made something similar for the gbc using the same assets called 'sonic advance 5' in chinese and the sunglasses sonic's life icon has is retained in this version. So it probably is related since it uses similar resources.
