Index 75 is one too large for AR_TABLE[75], DR_TABLE[75].
This error was reported by cppcheck.
hw/fmopl.c:600: error: Buffer access out-of-bounds: OPL.AR_TABLE
hw/fmopl.c:601: error: Buffer access out-of-bounds: OPL.DR_TABLE
Fix this by limiting the access to the allowed range.
MultiArcadeMachineEmulator has newer versions of fmopl,
but using these requires more efforts.
