I've just noticed that GoodGen doesn't seem to have the European version of ESWAT in its database, having just the Japanese and US versions (which are versions 00 and 01, respectively). Has anybody here checked which one of those lays inside the Euro cartridges? There may be an undocumented version 02 in there, who knows.
According to no-intro the EU carts have the US ROM... (their horribly outdated undumped list from mid-2009 says they don't have a PAL dump, so I guess that means PAL was since dumped and found to be US? nothing in their log that I could see says this so it might still be unverified...)
