v1.5 increased the size of GSaveLightMemory by 0xC each; with 160 entries, everything stored after this field (at 0x2F84) increased its offset by 0x780.
GSaveItemName ClothesPTops; // @0x14c size 0x8, align 4

Should be possible to convert the first revision of villager data to the current format and vice versa. Someone would need to document how they pre-fill these new fields (listed above).
Change friendship here.
Can also cheat all friendships (of all villagers, for all saved players) to 255 by shift clicking the drop-down button instead.
jp/en/zh -- only english has been translated (duh)
keep in mind this translates the text in the program, not the internal flag names.
not sure if other languages need to be supported; from PKHeX's experience, only spanish is updated (besides jp/zh), as most users speak english or are fine using the program in english.
pls localize villager names and item names for non-english :P -- preferrably automated from raw game dumps
