/* im not sure how to write the base for this function
* Repeater/Patch Code
* 5000XXYY ????
* 8ZZZZZZZ VVVV
* Used to make extremely long, sequenced codes shorter.
* XX is the number of addresses to be written,
* YY is the offset between addresses,
* ???? is the amount to increment the value (VVVV).
* Note that this increment is signed, so values higher than 0x8000 will
* subtract from VVVV rather than being added.
* These can be preceded by any 'D' code type (EG 0xD0144604 0022)
* to enable them on demand. The code to be repeated is not limited to constant writes.
* Any 80/81/88/89 code type appearing below a '50' code should work.
