"Could not disassemble" on Windows

[andrigamerita]

Hi, I'm sadly experiencing that there is a breaking issue in your program:
On my amd64 Linux machine, everything seems to work just fine, but on Windows I get an error every time I try to disassemble any ROM (nessemble rom.nes --disassemble). The same ROMs obviously disassemble fine on Linux with the latest build.
No matter if I call the program from cmd or msys2, I always get:

Could not disassemble `rom.nes`: Could not read `C:\path\to\rom.nes`

I don't get any other output from the program, and I can't get a clue at what in the source code could ever be making this issue arise on Windows but not on Linux.
