Actually, the _only_ instructions that can do an 8-bit zeropage address
with a Y index, are LDX and STX. Everything else always uses a 16-bit
address if indexing with Y (DASM will silently do that for you.) It takes the same 4 cycles in either mode, so it doesn't matter except
for the one extra byte of ROM.
