If set, Adlib/OPL emulation will signal 'overflow' on timers after 50 I/O reads.

This is a temporary hack to work around timing bugs noted in DOSBox-X. Certain games (Wolfenstein 3D) poll the Adlib status port a fixed number of times assuming that the poll loop takes long enough for the Adlib timer to run out. If the game cannot reliably detect Adlib at higher cycles counts, but can reliably detect at lower cycles counts, set this option.

NOTE: Technically this decreases emulation accuracy, however it also reflects the fact that DOSBox-X's I/O timing code needs some work to better match the slowness of the ISA bus per I/O read in consideration of DOS games. So this option is ON by default.
