osPiReadIo was stubbed to return 0, so token.c's cartridge-token read
always produced an empty string and N64 debug switches (-level_09,
-hardN, -m*) were silently ignored -- the game could only ever reach a
level via attract-mode demo playback. Synthesise the token string from
argv[1..] (sysGetTokenString) and serve its bytes from the 0xFFB000
range in osPiReadIo, so -level_09 now boots straight into BUNKER1.
Empty when no args are passed, so no-arg (attract) runs are unchanged.
