A bit off-topic, but for the opening_plugin.rco, it's a little weird - some languages don't appear to be compressed, but I can't really figure out what it is exactly.
Here's a manually decompressed opening_plugin.rco (I'm never going to do this again - such a pain to do >_<) but the text from the following languages is "wrong": German, Russian, Korean, Chinese (both simplified and traditional).
