beta aberdeen, beta thousand white qr were not hidden at all
Shenhua's house, Ziming's house were 'available' in cut scenes so that is way they were 'accessible' after all
Don't rush and think what have to be achieved at the moment to enter any map
Folder with specific name and contents: xxx.PKF and xxx.PKS (this xxx stands for MPK00, but let's say the name is not relevant, as we look for hidden files) and there also should be file name mapinfo.bin (just like the 'name' condition it may differ, even not be present at all).
The actual map should be put via IPAC at the beginning of file to be loaded from save. There are probably more maps inside every pkf & pks so we should test every possibility available...
After all, all of us are pretty sure this bailu village maps (if!) should be stored on GD4 disc. What about the folder? Probably also one of last we can actually explore (this would be kes1?) or folder which wasn't load while we played the game... no KSH1 (Shenhua's current house) that's for sure as we break it into pieces (Shenhua's House and Hazuki's kitchen, nothing else to search for I'm afraid)
