Bootix v1.2

A few small additions!

• Adjusted DIV timing to fully match up that of the original bootrom
• Added bootrom-variant for Gameboy Pocket (MGB)

Bootix v1.1

Lots of Fixes!

• Optimizations for code size, allowing for more space for potential future additions
• Fixed DMG initial register states (don't know how I could miss that one)
• Adjusted timing so DIV register now has the same value as with the original bootrom

Bootix v1.0

Initial Release of Bootix!

This includes a custom bootrom for DMG models. Apart from the registers DIV, STAT and LY all I/O registers result in the same values as the original bootrom. (Tested using mooneye-gb test ROMs)
