My latest app for Minecraft:

MCI Fireworks adds Fireworks to your Singleplayer Inventory. Each bunch of 64 Fireworks properties are randomly chosen based on your settings.

Select a World, Select your setting and Hit the button! When you load the world in Minecraft you will have an inventory full of fireworks.

- Download (Requires Windows XP or Higher)

Note: You need Minecraft v1.4.6 or higher as lower versions do not have fireworks.

Can you make a mac compatible one please?

Nope. You may be able to get it to work with Wine.

Though i have no clue as i use a PC. (Mac's should be avoided as there is less software for them, they are more expensive and Apple makes them)

What language was this written in Stucuk?
