Do you need new ColecoVision games with more RAM and avanced
In this case, will the new ColecoVision Super Game Module be hard to come
This device was to mark ColecoVision's 30 years
anniversary back in 2012.
The new Super Game Module from Opcode Games, is a
new hardware for use with our ColecoVision video game console.
There are now 2 versions of this new little wonder.
The hardware in version 1 is basically produced under public license from River West Brands in Chicago, and therefore an official
Coleco product under applicable law.
But it is a Opcode Games product, and therefore is version 2 more basically Eduardo's
The hardware from Opcode Games in both
versions is an RAM expander with built
in MSX sound.
The new MSX sound chip is far more advanced than the regular PSG found inside the
So it is a significant upgrade in terms of sound and opportunities.
A little story:
200 Super Game Modules from the first and second round was quickly sold out.
The first Coleco version from Opcode Games,
2012 to 2016 was compatible with
the U.S. NTSC, EU and Australian PAL and ADAM Computer Systems.
In December 2016, an updated version of SGM was launched, and this module
became compatible with the French CBS Scart ColecoVision.
The Super Game Module allows you to run the
so-called ColecoVision Super Games.
You can recognize a Super Game on these brands below:
These labels is to find on the package, as well
as on the
Some Super Games from Opcode Games
have a production number which always starts with SG for Super Game.
The Budget Color Line series with RC 24XX.
And in a combination together with the new
SGM, is a new cartridge PCB for all new and upcoming Premium SGM games produced
from November 2016.
This new PCB are named ColecoVision Super Game
Cartridge or just (SGC).
SGC will not be used for the Budget Color Series which for now is 19 ColecoVision games, they use instead the MegaCart 1.
SGC is powered with a very avanced Bank switching and with Save features be a lot advanced.
Save function is based on EEPROM, with data retention of 100 years and
endurance of 1 million write cycles.
With that means you are able to play the game 1 million times on
average before the EEPROM fails. So no need for battery at all.
The new ColecoVision Super Game
Cartridge can also be used with regular ColecoVision games.
The SGC will be backward
First announced Super Games from Opcode Games that get use the new Super Game Cartridge
was Penguin Adventure and Gradius.
And for this to be done, there was made a brand new PCB board for this new
The idea for the Super Game Module and new cartridge PCB is to make more complexed games for
The Opcode Super Game Module upgrades our current ColecoVision video game console from its standard 1 K RAM, with
extra 32 K RAM.
All 3 versions of the Super Game Module has also a
more avanced sound chip inside than the one inside in our ColecoVision.
This avanced sound chip was one of the most known out there in the 80's, namely the AY-3-8910A.
AY-3-8910A was already a known audio chip, for example in some MSX
computers and earlier arcade machines.
The Super Game Module is just an simple expander for more RAM and better
sound, there is no graphic chip inside.
The great games is in the Cartridge itself. (all codes incl. graphics).
Eduardo at Opcode Games has already converted several games from
MSX1 and Sega SG-1000 titles, and some of those are already available for our ColecoVision.
All titles below are converted 80's games.
Released under the Opcode Games label is: Space Invaders Collection, Sky
Jaguar, Yie Ar Kung-Fu, Magical Tree, Road Fighter, Pac-Man Collection,
Gradius and Penguin Adventure.
Non released, but originally planned was: Comic Bakery, Exerion, Galaga, Super Hang On,
Hyper Rally and Track &
Eduardo do also convert games for CollectorVision Games and Team
Some with the SGM, and also many before the SGM came out.
Many new programmers has opened their eyes and
now making their ColecoVision games for the Super Game Module.
They already know they can detect the 24 kb. of RAM, and the AY sound chip
for a nice and different sound than we were used to.
Some programmers are skilled at combining the SN and AY sound chips for
even more varied sound.
Programmers don't need to stop at the 32kb. barrier.
Is the game bigger than the 32kb., is Opcode Games ready with both the
MegaCart1, (MC1) and the Super Game Cartridge (SGC).
MegaCart1 supports both ColecoVision and the Super Game Module, but Super
Game Cartridge supports only the Super Game Module, and can not work with
an ordinary ColecoVision.
SGC and SGM is combined to each other.

Most of the games above have never been released to
our ColecoVision platform before, other upgraded for better sound.
All upcoming games from Opcode Games will be launched as expanded games, and will require the Super Game
Module to work.
All the Premium games from Opcode Games has improved sound and graphics
save game features.
Improved graphics means colors like it would have been in a real Arcade
Improved graphics only applies ColecoVisions or other copatible consoles with
either the F18A Graphic card
installed or via FPGA.
Also planned Super Games is Phoenix, Kangaroo, Berzerk and Moon Cresta, but
those games is long term Super Games
projects together with DKA.
But of course not all upcoming games will require this Module, few upcoming games from
Team Pixelboy and CollectorVision will not all make use of the Super Game
When ColecoVision was launched in the U.S. in August 1982, was it an early "unfinished" MSX-based
Right after came the first and more "finished" SpectraVideo 318
who also was an unfinished MSX machine ,but closer to the actual MSX1.
Sega SG-1000 was also built
up around the Z80, same resolution, same Video processor, 1K RAM, 16K VRAM and
even the sound chip was the same as ColecoVision.
So games from ColecoVision and Sega SG-1000 was very similar and easy to
But also games from MSX1 are close in its structure, same CPU, same Video
processor, but the first MSX standard changed the sound chip to AY-3-8910.
It was MicroSoft in Japan who starting up this
MSX stands for: MicroSoft
(an act of giving and receiving from one MSX to another MSX and vice
So practically all those "finished" MSX games from the
mid 80's can
now be translated back
to ColecoVision with very few changes.
When ColecoVision was at its highest level in 1983, came MSX to the world
as a new standard for MSX Home Computers.
All the MSX1 standards could now "talk together" in some way.
This also applies for the Sega SG-1000.
And here comes the new Super
Game Module into the picture.
We already share the same CPU and Video processor.
ColecoVision og SG-1000 has even the same sound chip, but it is the number
of RAM that which is the difference.
And with the AY MSX sound on our Super Game Modules
and converted MSX games
can we get our ColecoVision much closer to the MSX.
The AY-3-8910 sound chip is a step forward from ColecoVision
and Sega's own sound chip, namely SN
The AY-3-8910 is the extra audio chip inside of the 2 versions of
the Super Game Module, and it is
also used by lots of other homecomputers and arcades in the 80's.
The Super Game Module can detect both audio chips individually or at same

almost all upcoming games and almost all the existing games will work without any problems.
You don't have to unplug the Super Game Module from the expansion
port if you don't play the Super Games.
You can safe let it be there without any problems, except for the
following games: Bomb 'n Blast and GameSter81/Game on Expo.
With these two games will your SGM then have to be disconnected.
You can always play regular ColecoVision games with the Super Game Module plugged in at any

Eduardo at Opcode Games joined Andre Lamothe at Nurve Networks at the now
former XGameStation with his new idea, and
they redesigned the unit from the buttom.
Andre gave Eduardo the technical advice so Eduardo could continue his work.
This is the former start-up sequence from the earlier Opcode Games.
It was planned to remove the start-up sequence from the cartridge, and let
it show from the former "Super Expansion Module/SEM".
But it was dropped again and it is now back on the cartridge in a new

This is the new start up sequence.
This new sequence will replace the old start-up sequence
shown above with this new animated one.

- Programmable AY Sound Generator for the 2
The sound in the 2 version of the Super Game Module is provided by the
The same used with
almost all MSX computers and many other
computers and arcade machines from the '80s.
The main reason is to allow more faithful ports of MSX and the most Z 80
based arcade games.
The people who created the ColecoVision made a bad mistake with the CV PSG. The CV
PSG isn’t bad at all, but they clocked it too high.
Because of that, we are limited to frequencies above 110 Hz, which means,
that deep bass sounds can not be produced by the ColecoVision.
So that is why the Space Invaders Collection marching sound in SIC isn’t
as deep as you remembered it,
or some music stuff sounds so “high” in the frequency range.
The new PSG corrects that, and goes beyond what the Texas ColecoVision PSG can do,
with volume envelope and better noise generator.
The AY helps by offering a wider frequency range and by increasing the
total number of channels available.
Additionally both PSGs can be used simultaneously, and all sound is routed
to the RF output.
(A/V mods can still work if the sound source is taken from the output of
the sound mix, just before the RF input).
Eduardo decided for around 15 years ago to make the
old Donkey Kong
game in an strong and improved ColecoVision version, than the original 1982 ColecoVision version from Coleco
So for the best sound studied Eduardo 6502 assembly, and by consequence he was able to analyze the Famicom / NES
version of Donkey Kong.
With that he have the routines he need to be able to reproduce the few
analog sounds found in the real arcade game.
One set of sounds for the SN chip, and another set for the AY chip.
The Dutch musicmagician
Maarten van Strien also called Wolf has unfortunately turned down its
DKA., he does not have the time to help with the sound this time.
So Eduardo must find another one who will be creating the opening tune for
The DKA release is delayed until Q1 of 2018.
There is for now over 1000 people on the waiting list.
All new Cartridges will be produced and assembled in China and published
via AtariAge Store.
With the new Super Game Module and a related Super Game, will you have a sound you never have
heard before from your ColecoVision, believe me.
What about graphical options.
About graphics, the SGM doesn't change the internal graphic chip from
ColecoVision, but the extra
RAM can help graphics in many ways.
One can for example create one or more frame buffers for dynamic parallax
scrolling (by dynamic means planes that can be modified on the fly).
Or have a dynamic pattern table in RAM. Or have a lot of movable objects
on screen using tiles.
Those are things you simply cannot do well with a single KB of RAM, and
animating right from the VRAM is too slow for practical purposes.
Another example is smooth scrolling. You can do that in ROM, but then you
are going to need a huge cartridge for all the pattern variations.
With the SGM even a regular 32KB cartridge can offer smooth scrolling in a
game with several different stages.
Not to mention games that are a lot more complex.
How can you create a huge RPG that keeps track of hundreds of items and
enemies scattered all around the game world. ?
With 1 KB you cannot.
So the amount of RAM Coleco included with the ColecoVision simply restrains the
system from its full potential.
So many examples, some of the best chip tune players out there uses self
modifying code and you cannot do that with 1 KB.
For ColecoVisions with the installed F18A Graphic card, have you
automatically more Colors, no Flickering and a perfect scroll in all

Opcode Games had originally a plan about advertising his Super Game Module through Gaming Magazines, Youtube,
Retro Gaming Websites, Merchandise etc.
But it is only announced via Opcode Games website, Facebook, AtariAge.com
and some Retro events.
But the Internet is fast, very fast, so the news was
quickly spread all over the world in no time.
And like Eduardo says to ColecoNation for a years ago:
"For us collectors and classic gaming fans alike,
is increasing lifespan for our consoles very important, because we are already witnessing
our beloved machines is slowly dying.
That is a concern when creating new devices".
Full support and technical documentation of the Super Game Module and the ColecoVision Super Game Cartridge
is available for everyone who works with ColecoVision programming.
Consult Opcode Games, just note that, they can
sometimes be very busy,
(Travel a lot between USA and Brazil),
and therefore not
always quick to respond
And here are some technical details about the RAM expansion.
Some of you programmers are well aware, ColecoVision work RAM is limited
to 1KB, mapped from 6000h to 63FFh, and then mirrored to 6400h until 7FFFh
(so 8 times).
The ColecoVision also includes 8KB of BIOS routines, mapped from 0000h to
The SGM expands the work RAM from 1KB to 32KB as a maximum.
Here is how:
24KB can be mapped from 2000h to 7FFFh. When mapped, the internal 1 KB of
RAM is no longer accessible. All legacy software still works normally
under this mode.
However, since the SGM must also be compatible with the ADAM, the 24 KB of
extra RAM is NOT enabled by default.
In order to use that expanded memory in a ColecoVision system, the
programmer must first enable it.
But before doing so, you also need to make sure the module isn’t attached
to an ADAM system, otherwise there may be a memory conflict with potential
for damaging the ADAM and/or the SGM.
So the first step is to check if the 24 KB are already available. If they
are, then you have an ADAM system, and the SGM expanded memory should NOT
If no memory is found (in the 2000h-5FFF range), then it is a ColecoVision
system and the expanded memory can be enabled.
To do so, set bit0 in I/O port 53h to 1, like this (in assembly): LD
A,00000001b ; OUT(53h),A
You can also map 8 KB of RAM (for a total of 32 KB) to address range
0000h-1FFFh. However, when doing so, the ColecoVision BIOS will be
RAM and BIOS can be mapped back and forth, though. To map RAM to the BIOS
area, simply set bit1 in I/O port 7Fh to “0”.
In order to keep full compatibility with ADAM systems, all bits in I/O
port 7Fh must be set to specific values, though. Here is how you should
set the port: if you want the BIOS, set the port to “0001111b”.
If you want RAM instead, set the port to “0001101b” (see example above on
how to do that in Assembly). Make sure you respect those values, or your
game may not work on ADAM systems.
Eduardo has planned to release complete ASM libraries for detecting ADAM, SGM,
and then setting RAM appropriately.
Eduado at Opcode Games recommend using those libraries, so that we can
eliminate the risk of enabling the SGM expanded RAM on ADAM systems.
Here are the steps required to initialize a Super Game Module game:
1) When initializing your game, use RAM in the 6000h-63FFh range,
because the SGM expanded RAM is disabled by default, and you must make
sure it isn’t an ADAM before enabling it.
2) Run some memory tests to establish if RAM is already present in
the 2000h-5FFFh. If it is, then you have an ADAM system. In that case,
DO NOT enable the expanded RAM. Go to step 4
3) If no memory is found, then we have a ColecoVision system, and
the SGM expanded RAM can be enabled. Do so by setting I/O port 53h to 01h.
You shouldn’t disable expanded RAM after that (i.e., do not access I/O
port 53h again after initializing it).
4) Now that you know that 24 KB of RAM is available, your game can
start using it.
5) Optionally you can replace the BIOS with RAM, using I/O port
7Fh. Make sure you only use the two values described above (‘00001111b’,
‘00001101b’), or your game may not work on an ADAM system.
Eduardo finally note about the SGM and ADAM: AFAIK, I/O port 53h isn’t used
by any known ADAM device, so it should be safe to use the SGM with all
ADAM expansion cards in place.
However Eduardo cannot guarantee that a future (or even current) device
will not use (or may be already using) that specific port.
Users must make sure there is no other device in their ADAM system
using port 53h.
Basically would Eduardo like to see the routine, programmers are using for
the SGM detection, and also make sure that programmers don't touch the memory
Eduardo at Opcode Games will share the detection routines, but programmers will
also need to come up with their own routines.
More specifications will follow for the Audio at least in 2018.
As an programmer you now have the ability to make games for Colecovision
with no limitations.
So you can now program more advanced games, not to mention the
F18A is not out yet for a wider audience, but already now can you program
your game to detect it.
SGM: Bigger games, expanded sound for 2x Sound chips.
SGC: Very big and avanced Super games, plus Save game features.
F18A: Graphic card, smooth scoll in all directions, more colors at
your wish, no flickering with Sprites.
Many talented programmers is already jumped aboard and hopefully soon
we will see games that were created to the SGM from scratch.
Super Games will be
taking full advantage of the extra RAM and Sound.
Games that blow away our condemn of what a ColecoVision game looks and play.
