The DOS version lacks a mechanism to regulate speed when played on systems faster than it was intended for.
The computation of sine and cosines was similarly done using only integer arithmetic. All angles were represented using not degrees, but 1/256th of a circle. A lookup table contained the value of the sine multiplied by 32767. Multiplying this value by a 16-bit coordinate gave a 32-bit value, and the 16-bit high-half of that result was used.
The DOS version was written in C.
