The corruption is caused by the source of Yellow MissingNo.'s front sprite, at 0x0006 in the ROM. Here the dimensions of Yellow MissingNo.'s front sprite are 0x0 which is apparently interpreted as a size of 256x256. However, in the base structure it is $AD (10x13). Yellow MissingNo.'s back sprite pointer is at 0x0D0C in the ROM where its dimensions are specified as 6x6.
