How do i build this?

In order to build Toystar, you will need:

• A x86_64 cross compiler and NASM
• Git
• Xorriso
• WSL or a linux VM (if you are on windows, like me)

Clone this repository and replace the variables in the makefiles containing the name of the tools to be used. After that just type make. This will download Limine and create an iso file, which then can be run using QEMU.
