INFO

The Chip8 system could be considered as the Flash player of the 70's. It allowed making games and animations that would run on different machines.

Chip 8 was introduced by RCA in 1977 on the Cosmac VIP computer. The little blue machine ran at a whopping 1.7609 Mhz processing speed and had 2 KB of RAM storage.

It was a "hobby computer", sold at $275 that you had to build yourself!

Over the years, CHIP8 has been
emulated in many devices.
This particular version was
coded in Actioscript 2.0, based
on Chip8 documentation.

Early game consoles such as the Atari 7600,
the Intellivision, or even the NES, were
programmed is a similar (albeit more
complicated) fashion. You thus can see what
hobbist game developers did back in the day
with the games and programs presented above.
Some of them are almost 30 years old!

The Chip8 became popular again
in the late 90s, as hobbist
HP48 calculator programmers not
only emulated but massively
enhanced the Chip8 platform.

The "Super Chip8 " (schip8) doubled the screen
resolution (128x64 pixels instead of 64x32),
introduced a few scrolling routines, and
allowed for larger sprites. This overhaul was
followed by much nicer looking games.
SCHIP8 support in this emulator is still being
worked on and about 70% done.

To understand how emulators
work, you need to know a few
things about "computer speech".
At their core, computers only
know about electricity.

Like a lightbulb, they only know if something
is on or off. All our modern computing power
is based on how we can encode enformation with
this premise. We call these basic atoms of
information "bits", which are either on or
off, either true or false, or as we commonly
write them, either 1 or 0.

As you can imagine, getting a
computer to do something with
just 0s and 1s would require a
lot of time furiously working
with a light switch...

To make the task easier, we can encode the
information in another format. If we group
four bits together (from 0000 to 1111), we can
make up to 16 possible combinations. We call
this group of bits a "nibble", and they can
contain any value from 0 to 15.

Using nibbles, we can reduce
four characters into two when
talking to the PC. But wouldn't
it be convenient if we could
use only one character?

Enter hexadecimal notation. It's a way of
counting numbers with sixteen fingers! That
is, you can go up to 15 before having to add a
character to the left, and going back to zero
with you first character. We write the "extra"
(from 10 to 5) with letter, i.e. A to F.
Starting to look familiar?

A nibble is still too basic to
represent many things. They are
therefore used in pairs, which
everybody knows as bytes. 8
bits allow up to 256 values.

Thanks to hexadecimal notation, we can write a
byte using two nibbles. This is why graphic
programs usually ask for color information in
hexadecimal. They encode each color component
with one byte, in RGB format (e.g. #FF003C)
This allows choosing one from more than 16
million possible colors!

Bytes are used by much  more
than colors. ASCII text encodes
each character in a byte. This
text uses one byte per letter,
space, or punctuation!

Computer programs are also written in
hexadecimal, what is commonly called "machine
language". Anything that a programmer writes
has to be converted to Machine Language before
the PC can run it. Even Actionscript!
But although every CPU will use hexadecimal,
they all understand a different flavour of it.
A PC won't understand a Mac.

An emulator is a program that
understand the machine language
of a CPU, and can translate so
another can run it instead.

In the past, most emulators were hardware
based. But today home PCs can emulate many
older systems purely in software. We make the
hexadecimal program believe that it runs on
its native environment by providing an
accurate simulation of what it can perceive
(guess where the Matrix got the idea).

In practice, we run a virtual
CPU that reads a program from
memory. The memory itself is
built to simulate the behavior
of the original chip.

Each address in memory is coded by a number
(like a mailbox). This measures how large
memory is; RAM of 1 MB means it has one
million mailboxes that contain one byte each.
The CPU will then go back and forth in memory
looking for the next instruction to run. How
complex or complicated these instructions are
depend on CPU.

Let's take as an example the
"goto" function in Chip8. We
need to tell the CPU to jump to
a specific location in memory
and continue to run from there.

Since "goto" is one of the native Chip8
commands, this is easy to do. Hex value #1e12
will tell the CPU to jump to addres "e12" in
memory. And that's it!
Notice how the command shown above is only two
bytes in length. Chip8 only recognizes
commands this long, which makes it easier to
read its programs.

You may have noticed that, if
you can only give commands
using four nibbles, the maximum
RAM 'mailbox address' you can
try to reach is "fff".

FFF is exactly 4KB of RAM though. Since the
original COSMAC VIP shipped with 2KB... that
was more than enough! The whole thing would
crash if you tried to read outside of memory
range. These sizes are laughable today (my
laundry washer packs more memory), but mere
kilobytes were expensive back them!

In addition to native commands,
the CPU needs to know where to
read and write information. The
most efficient way is to store
the values inside the CPU.

Every CPU has a set of special 'mailboxes'
where it stores temporary information. A few
commands will copy data to and from memory,
but every other command will never access RAM
directly. These are called registers. Modern
processors also have a "cache" - a few KB of
super fast RAM for more complex operations.

The Chip8 registers are fairly
simple. It has sixteen 8-bit
registers (called the Values),
and one 16-bit register used to
point to a memory mailbox.

Machine language progams then have to use the
registers as best as possible, using the CPU's
limited instruction set.
For example to sum 9 and 25 in Chip8 we would:
1) Set value register [0] to 9:  (#6009)
2) Add 25 to value register [0]: (#7019)
3) Copy result to memory at address FF:
(#A0FF then #F055)

Let's quickly analyze our
program. It was 8 bytes long,
but half of it was to write the
result to memory. Good thing
that we have many registers!

The first instruction (#6009) is decoded as
follows: [command][register][value].
6 is the "set" command, the register's name is
0, and the value to set is 9.
The second command (#7019) has the same
format. '25' is written #19 in hex.
The last two commands are a bit different.

The last two instructions are a
good example of different
command formats. (#A0FF).
[command][memory address].

This command tells the CPU to set its "memory
mailbox pointer" to a specific address.
Predictably, the next command tells the CPU to
write to whatever address is being pointed to:
(#F055) is: [command][register][save].
All the different formats are described in the
CPU's documentation.

This emulator effectively reads
each one of the CHIP8 commands,
and runs it on a virtual
machine. It also makes flash
simulate screen output.

You could actually write your Chip8 programs
and run them with this emulator if you were so
inclined. The sheer complexity of it would put
most off it though. Nonetheless, many like to
code in machine language (also called assembly
language) because of the challenge and high
performance that can be obtained through it by
a skilled programmer.

If you would like to see the
commands being decoded by the
emulator, you can activate the
debugger by clicking on the
appropriate button on the left.

The debugger will show you in real time what
is contained inside all the CPU registers. It
will also show the command it is currently
running. You will be able to see how complex
games such as Tetris make the CPU jump all
around memory. You can also use the debugger
to find out if a program is doing anything or
if it is waiting for keyboard input.

The Chip8's keyboard has 16
keys. They are mapped to keys
on the left of your keyoard
(see the cheat sheet under the
CHIP8 box on the left).

Since games were programmed in different
platforms, the keyboard layouts will be a bit
different. Presented here is the original
COSMAC VIP layout, but some games use the keys
a bit differently. Try to find out which keys
are being used if one doesn't work.

As a closing note, note that
Flash also uses a special kind
of machine language, and so the
Flash player is a bit like this
emulator.

The "bytecode" contained in SWFs are
hexadecimal commands converted from
Actionscript. It is even possible to write
Flash programs in assembly directly. You can
google for a program called "Flasm" which
allows you to write Flash programs directly in
bytecode. Somebody has even created quite an
impressive 3D engine using it!
