Welcome thewalll28, you must be new to MSX! 
See for example some posts by user snout in this thread
Basically: a dirty fix to get some sloppy written software to work... The "POKE -1,170" was the version most often encountered, used for Philips machines like NMS8250 etc. If you encounter it (and if it's really needed to make the software work), change to:
POKE -1,(15-PEEK(-1)\16)*17
(note the backslash = not the normal, but integer divide)
,save, and forget about it. It will determine the right value to POKE for the machine it's running on. Oh btw: I take credit for figuring out above version of POKE -1 LOL! Short, and 15,16,17 sequence made it easy to remember.
