A pong (the 1st computer video game?) in <255 bytes;
I'll give the hexcode 1st to see if there's any takers. Needs DOS.

In a similar vein: Tetris in 256 bytes
I took John David Chapman's 1999 code & reduced it by 30 bytes
Here's the text from his source:
;----------------------------------------------------------------------------- ;
; [] TET - 256 byte Tetris [][][]
; [][] []
; [] by []
; [] [] []
; [][][] [][] James David Chapman [][] [][] []
; [][][][] [] [] [] [][] [] ;----------------------------------------------------------------------------- ;
; Here is a 256 byte version of of the all time classic game Tetris...
;
; To play, use the left and right SHIFT keys to move the current block, and
; the ALT key to rotate it. Press CONTROL to exit.
;
; I have not had the amount of time that I would have liked to write this ;program, so am sure that there is some optimization still left to be done. If ;you find a saving somewhere along the line, do let me know.
;
; Another idea for a 256 compo? - 256 scramble. Could be fun.
;
; James David Chapman 1999. ;----------------------------------------------------------------------------- ;Features:
; Cool looking blocks Almost as good as graphics mode ones.
; Random shape Taken from the timer.
; Random colours Also taken from timer.
; Rotatable shape I hated writing this bit, as expected. ; Block stop check Stops blocks when they hit another one ; Solidity Prevent sideways crashing into blocks. ; Dual loop timing Allows for multiple input per advance. ; End of game effect More of a useful side effect really!
; Full lines removed A quickly cobbled together routine.
; Frame Sets a maximum 10 block width for game. ; End program key Better than using Control-C etc.
;No space for:
; Scoring +2 for a line, +4 if the bottom line.. ; Beeps a simple beep on line removal...
; Speedup should increase in speed over time...
; Graphics mode I had a lovely graphics version, and
; Nice enlarge effect a cool block effect which was too big. ;----------------------------------------------------------------------------- [[code]] ;-----------------------------------------------------------------------------

I've used the saved space to tick off the beep on line removal [8] & a simple score [22]
(1 point per line cleared)
Here's my hexdump:

WK: used DOS int 21 for the beep, int 20 for exit
