Filesystem/Race/Common.szs/ItemSlot.bin

ItemSlot.bin is a sub file of /Race/Common.szs. It contains a set of tables used for Item Box Settings that control the item roulette probabilities in race. In competitions, Nintendo also used a variant that can be used individually in specific courses, named ItemSlotTable.slt.

File Format

Bot ItemSlot.bin and ItemSlotTable.bin share the same table-based format, and the difference between them is that the latter lacks of Battle mode tables originally. However, the file would still work if replaced with a full ItemSlot.bin set of tables.

Offset	Type	Description
0x00	Byte	Number of columns C.
0x01	Byte	Number of rows R.
C + N	Byte	Item chance cell corresponding to the R row from the C column. In original files, this value is a range between 0 to 200, being each unit a 0.5% of chance, and all rows in a single column add to 200, but neither of those is required for the slot table to work.
