*Each cartridge will be tested on a shell free system to verify full functionality before shipping. *Confirmed!: All hidden characters & bosses are instantly selectable without the need of entering long codes. Prerequisite: you must have a debug bios kit installed in your AES.
No extra work is required, simply having this chip installed allows you to select all characters from the character select screen during any mode of game play (arcade, vs., & practice). You can still play the hidden characters without the debug bios, but you will need to enter the required codes manually. English version SVC Chaos flyer:
