Dumb, nooby question: How do you find the syntax error? I don't see a line 0 when I'm in the edit screen. I'm assuming this error message is saying it's the 2nd character? For context I found a site with old BASIC games so I typed in a Russian roulette one because it looked shorter.

The former is the slot number, and line number in which the error occured is the latter.

If you press the 4th function key, (the one that says "LIST ERR") it will take you to the editor and put your cursor on the line that made the error. Also, most BASIC games won't work at first because of differences between BASIC and SmileBASIC​.
