How to Play Barcode World
Quick start
Prepare Barcode Butler II and a dedicated connection code, and start by collecting multiple 13-digit barcodes that can be read. The first two will compare their HP, ST, and DF, and will also look at the roles of warrior and magic type. On the map, advance by defeating the enemies in front of you, and at the space station, talk to the doctor twice before registering your friends and equipment. If the next enemy is stronger, return to the previous planet and fight again, concentrating on training the main force that will grow well.
Controls
Use the cross keys to move/select items, and press A to confirm. B opens the command menu and is also used to cancel. On the map, move the cursor to your destination and press A to move, then select battle, tools, change allies, equipment, warp, save, etc. from the menu on B. On the character and item registration screen, data is sent to Barcode Butler II through a code.
Barcode World — About this game
"Barcode World" is an RPG that connects Barcode Butler II to the Famicom using a special cable and creates characters and items from the 13-digit barcodes of products and attached cards. In the scenario, you register the first two main characters and advance through the 20 worlds of the Barcode Nebula in the order of enemy stars, space stations, and bosses. You can have up to 8 companions, but battles are one-on-one, and you choose normal attacks, recovery, magic, and tools to reduce HP. Instead of a general experience point system, your abilities may improve after victory, and if you can't progress, you can refight previous enemies. It also supports two-player matches, and the process of searching for real packages and testing unknown ability values becomes a game in itself.
