How did you unzip it? You need to fist open it in RGN_Tool, you'll see 'pk_text.zip' in the first section, press 'Save' to save the zip file somewhere convenient and then unzip that to find D414900.ver file and a folder named keyboards with many .kbd files in it. Note that they are meant for the Asian unit, it might 'brick' your US before conversion if you try to use some of them.
