queueRAM dd14dc9bbc Clear reset type bits in CIC seed values from PIF 
Some CIC seed values had bit 0x20000 set which is the reset type
indicated from PIF (1 = NMI, 0 = Cold Reset). Some games
follow different initialization paths for NMIs which can cause
some unexpected boot behavior during a cold reset.

Derek "Turtle" Roe 8b89df2fdc See long description 
Replaced all references to simulation with emulation
Updated copyright year
Updated .gitignore to reduce chances of random files being uploaded to
the repo
Added .gitattributes to normalize all text files, and to ignore binary
files (which includes the logo and the NEC PDF)

Seriously broken WinAPI stuff, no input, no multi-
threading a bunch of other terrible stuff (yet).
