/* 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.
