Here are some ways you could get key items if you don't have them:
* Cheating: You can use a Game Shark or other cheating devices to add key items to your inventory. However, this is considered cheating and can be against the spirit of the game.
* Trading with a Friend: If you have a friend with a copy of Fire Red, you could ask them to trade you the key item you need. This would require both of you to have a link cable and to know how to trade properly.
* Using an Emulator: If you're playing on an emulator, you can use save editing tools to add key items to your game.
* Finding Duplication Glitches: There are some glitches in Fire Red that allow players to duplicate items, but these are complicated and risky.
Important Note: It's important to note that using these methods to get key items could be considered cheating and might spoil the experience of the game.
If you want to play the game fairly, you will need to obtain the key items through the game's intended methods. These usually involve completing certain tasks or finding them in specific locations.
