The current official (new) Cash Shop interface and it's used item_cash_db.txt gives us 0 possibilities to make anything dynamic at all.
Maybe i'm unaware about some specific features, but as of now i wasn't able to find anything even related to the cash shop system that could be usefull.
So the only settings we've got are: // Type,ItemID,Price
But there's no way we could possibly set a time limited offer nor anything "Special" about the special section itself such as limited quantities or wha
I shared all that I had done with Lemongrass when they asked me about it via PM, however, no extra progress has been made beyond what I posted above.
I could only get packet 0x8ca to change the amount of pages displayed for the other tabs (including the results tab) but that was it. It could just be a red herring, or it could actually be a clue to make this whole thing work.
