Buena_PrizeMenu has "rept NUM_BUENA_PRIZES", which needs NUM_BUENA_PRIZES to be already defined. BuenaPrizeItems and BuenaPrizeItemsEnd are needed to define NUM_BUENA_PRIZES; but BuenaPrizeItems is defined after Buena_PrizeMenu. I don't see a way to avoid hard-coding its value of 9.
Contrast that with the NUM_MOM_ITEMS constants, which are not used as "rept" arguments and so can be defined within their code file.
(This is not expected to be their final location, but it makes them easier to relocate when necessary, and easier for users to edit until the whole project's file structure is finalized.)
