# Drop Tables Taken from work in discord posted by PJ - Drop tables for enemies, Eddie, and Proto Man. The enemy type, stage, and location of Eddie and Proto Man, all do not affect these tables. ### What Affects Drops *One of the values that is used to determine item drops is simply a table of random values whose entry is based on the total number of enemies we've killed.* *But...the other value that it looks at is unbelievably out of our control; every frame that any button or combination of buttons is pressed, it XORs that input's value (i.e. 0x20 for left, 0x02 for B, 0x22 for left+B) with the lower byte of the frame counter, swaps the digits, XOR's that with the upper byte of the frame counter, and increments the RNG byte by that amount.* *- PJ* ### Normal Enemies
