; Date : 1st April 2001
; TETRIS for MENUET
; Author : Paolo Minazzi (email paolo.minazzi@inwind.it)
;
; -Note-
; 1. This program requires a PENTIUM or higher because uses the RDTSC
;    instrucion for get a random number.
; 2. You must use NASM to compile. Compiling is OK with NASM 0.98, I
;    don't know what happen with other versions.
; 3. You must use the arrow key to move and rotate a block.
; 4. In the near future there will be a new version of TETRIS. This is
;    only the beginning.
;
; Thanks to Ville, the author of this wonderful OS !
; Join with us to code !
