// WORKAROUND
// Some versions have a script bug which allows you to freely click around
// during the sequence of Bud freeing the professor in part two which even
// allows Bud to leave the room while talking to the professor resulting in
// general glitchiness. The Spanish and Polish versions (and possibly others)
// fixed this by introducing the 'mof' opcode to disable the mouse during the
// sequence.
//
// The difference is as follows:
// Buggy: 61dw buw,148,125,wsm,buw,148,132,wsm,wat,050[...]
// Fixed: 61dw buw,148,125,wsm,buw,148,132,wsm,mof,pan,01,wat,050[...]
// ^^^^^^^^^^
// To work around the issue in the problematic versions we inject these two
// instructions after the first occurence of the 'wsm' instruction (which
// proves good enough).
