I reverse-engineered
TETRIS, created by
Alexey Pajitnov and
Vadim Gerasimov at
AcademySoft (
Computing Center of the USSR Academy of Sciences, Moscow) in 1986.
The original was written in
Turbo Pascal 3.0. I adapted the source code for
Turbo Pascal 7.0.
The code was restored from the original
TETRIS.COM, preserving the program structure: the same procedures, variables, and formulas as in the original.
