Changelog:
- icarus: new Firmware/ folder, which is used to import external
firmware when it's missing from the ROM image
- icarus: improved Super Famicom heuristics; including Shift-JIS to
UTF-8 encoding of game titles
Errata:
- if firmware isn't appended, it still cuts out the size from the
memory/program.rom file
- boards.bml is still missing the new Japanese production boards
