About
Meteor is a high-accuracy Gameboy emulator for Windows. Meteor's goal is to emulate the origonal hardware as
accurately as possible as opposed to using high level emulation to mimic the behavior of the origonal hardware.
Meteor contains sub-cycle specific emulation code to emulate the origonal hardware even between processor
instructions. Meteor will never contain game specific fixes or patches to ensure a high level or accuracy.

Accuracy Testing
Accuracy Test Roms are programs written to validate perfection of the Gameboy's behavior. They are used by
emulators to ensure that the emulated console behaves as close as possible to the origonal hardware. While not
everything is ever known of a closed-source system they still provide a great estimate of an emulator's overall
accuracy. The following tables list the majority of the verified test roms and Meteors results.
