Uxn is a simple virtual machine. A Uxn program file is loaded into the virtual machine's memory starting at address 0x0100, and then execution starts at address 0x0100.
[edit] Identification
Any valid uxn file will have the first byte being a nonzero multiple of thirty-two, other than thirty-two itself.
A uxn file with metadata will have A0 xx xx 80 06 37 as the first six bytes, where the second and third bytes are a big-endian 16-bit address of the metadata (where the beginning of the file is address 0x0100).
