Rustual Boy - A WIP Virtual Boy emulator in Rust

This emulator is not quite complete, but covers quite a bit of the CPU, memory mapping, and video hardware. It also contains a basic command-line debugger supporting disassembly, mem dump, breakpoints, etc. Many ROM's are fully compatible so far, but there's still some fundamental things that aren't yet implemented, such as some floating point flags/exceptions, bit string op's, etc. There are also a few bugs lurking around :)

Performance isn't fantastic yet, but the emulator should be playable at least. YMMV. Naturally, I'd like to get the core emulation logic in place before focusing too much on that.

A more detailed status/compatibility section will be written when the emu is complete enough for it to be relevant.
