Csabo's 1K Memory

A game in 1024 bytes for the Commodore C16 or Plus/4.
Written by Csabo/LOD.
Finished 2002.09.15 - submitted for the 2002 1K GameCompo.


The computer plays a sequence of lights and sounds for you.
You have to repeat each sequence as it was played. There are
4 distinct sounds and colors. The length of the sequence
increases each time you successfully repeat it.


(in the 'menu') Return to play, or ESC to exit.
(in the game) 1-2-3-4 for each light/sound.


Any Commodore C16 or Plus/4 (or an emulator of course).
The game works with both PAL and NTSC systems!
This software runs fine on all known Plus/4 emulators.

Technical details:

This was a very easy game to write. I remembered the idea
from the time when I was living in the United States. There
was a pizza place where they had a game machine like this.
You could play for a quarter. For repeating 15 sounds, you
got a free pop. For 21, you got a free pizza... I could
never go up to 21.

I saw that someone has also submitted a similar game for
the C64, referring to it as 'Simon'. I guess it existed with
that name as well.

Writing this game was my 'break' of coding. My other 3 games
are highly optimised, in this one I had lots of free space.
I used it to make the game look snazzy (e.g. raster bars).

The development time was one afternoon!


Use 'POKE 4878, [speed]' to adjust to speed of the game
before staring (e.g. if you find it too fast). The default
speed is 7. Lower values mean a faster game.

Use 'POKE 4386, [number]' to start the game from a longer
sequence. The default starting length is 1. Higher numbers
mean a more difficult game.

Type 'SYS 4127' to restart the game after Reset.
