apparently replies using 1a02 are dependent on the shopid? but the game doesn't seem to care
but there's only a few of them after the first unknown value:
		80 -> send_1a02(0, 17, 17, 3, 9); %% lumilass
		90 -> send_1a02(0, 5, 1, 4, 5);   %% parum weapon grinding
		91 -> send_1a02(0, 5, 5, 4, 7);   %% tenora weapon grinding
		92 -> send_1a02(0, 5, 0, 4, 0);   %% yohmei weapon grinding
		93 -> send_1a02(0, 5, 18, 4, 0);  %% kubara weapon grinding
		_  -> send_1a02(0, 0, 1, 0, 0)
