Opcode Super Game System...

It will probably be Eduardo at Opcode Games that have the strongest card to play out with.
Before this project can be a reality will at least 200 people need to confirm a purchase.

In the near future, maybe around 2018 or 19, will there most likely be produced a new world novelty.
We have seen it before, an console that can run ColecoVision games namely the Dina 2 in 1 and Bit 90.
Dina 2 in 1 was not an ColecoVision, but an console that could handle 2 kind of games, ColecoVision games and Sega games.
But Eduardo aren't building a two in one system. Everything is an extension of the ColecoVision + SGM.
This console will probably use the same kind of case that was used by the Atari Jaguar, but with new ColecoVision compatible hardware inside.

Eduardo Mello, the man behind Opcode Games LLC, will soon present us for a new super 8/16 bit cartridge based gaming system.
"It's a true new system that happens to run all ColecoVision + all SGM stuff, but it is also a full generation ahead from NES."

Eduardo's first CV2 plan is just to merge the CV + his new Super Game Module Pro into a new gaming console that can handle ColecoVision games.
The first plan was to keep the original CV case, and just replace the PCB and the metallic front plate.
This is however abandoned, and instead, will he go new ways with this new project.

When he first seriously talked about it in 2010, was it André from Nurve Networks who helped Eduardo with technical assistance.
Eduardo suggested his ideas, and it soon became it clear that the Yamaha chip V 9990 should be included in the project together with V9958.
But Unfortunately for unknown reason was André unable to help Eduardo with his project at that time.

One thing you can be 100% sure at, this new Opcode "Super Game System" (SGS) will contain the SGM Pro features and a bit more.

Something that he and his very good friend in Brazil Ricardo now is started to work on.
Ricardo Oazem is a very talented engineer he will be the one that are responsible for the new project.
Not sure if Ademir Carchano still is involved in the project.

Eduardo and Ricardo will add the functions as they mean will improve a new upcoming Super Game System.

The main goal with the hardware is to produce a machine that is up to 95% compatible with all the ColecoVision and SGM improved software.
If 99% is the goal, will the new Opcode Super Game System also support the Steering wheel, Roller Controller and the Super Action Controllers.
But not the Atari converter nor the ADAM Family Computer System.

Eduardo's philosophy behind the project is, to offer features, that can be used as a kind of options.
Custom color palettes, smooth hardware scroll, improved PCM, sampled voices and sound FX.
All of that can be added to games as options, so those with the new Super Game System can enjoy all that with improved A/V.
Video output will
probably require a VGA out, and /or a SVHS and for Audio either RCA (Phono) out or at least Mini Jack.

Eduardo has planned a number of functions not available with the Atarimax SD ultimate.

Eduardos new Super Game System is based on 80s tech with dedicated chips.
The Super Game System offers ColecoVision and SGM compatibility in a single solution, and extends that with 16 bit quality graphic and sound.
The idea is to create a new 8/16 bit platform for those interested in retro games, retro computing and retro programming.
It needs to be easy to use, easy accessible and fast.
The Super Game System implements Eduardos take on how he believe the ColecoVision would have evolved.

Therefore is the environment very close to MSX2+ but also close in its structure compared to the Sega (Genesis) Mega Drive.
One thing is 100% sure: There will still be a Z80 and a SN76489.

You can still play your classic ColecoVision games which also will includes the Super Game Module with Pro features.
In the future will there be developed games only for the Super Game System, which won't run on a regular ColecoVision with or without the SGM.

The new Opcode Super Game System console is more based on MSX and Sega than the ADAM Computer.
Expansion will probably be internal, and it isn't the same as the original ColecoVision, so no Atari Converter or ADAM Memory console to add.
It will complicate the planned structure, so it's a no go.

Instead refers to the original 1982/83/84 ColecoVision.

And the best part is the ability to detect and play the big MSX titles and other upcoming homebrew games.
Opcode Games implements his own code in those games and update with option screens and other improved things.
This consoles resolution could be up to 800 x 600 via the VGA output.
With F18A is the resolution 640 x 480.
The SGS will probably have different video outputs.

The new Opcode Super Game System will run almost all regular ColecoVision games + almost all Super Games.
It means that the Super Games System is backward compatible with your existing ColecoVision collection.

The new Opcode Super Game System will have a secret mode, where all new upcoming stuff will be mapped in.

The new Opcode Super Game System will accept all the ColecoVision controllers, but also older corrected wired Joysticks.

The new sound output can produce any sound you like, and can be sampled to lets say very close to the original from a given game.
That's very good for classic games like Wizard of Wor, DKA, Pengo, Bezerk, Moon Patrol and New Rally X.
But also games like R-Type and Salamander will be very good upcoming titles with its sound.

The beauty of having several sound chips is that the developers can use them optionally.
For example, can developers create a game for the regular SN 76489 AN sound, or they can make use of the AY-3-8910.
And not only that, you can also mix both sound chips with each other.
There are already games that supports both audio chips like: Comic Bakery, Mecha-8, Mecha-9 and Konami's Ping Pong.
But for some of the more avanced games will the new SGM Sound Pro be the new solution.

Here are Eduardo's tentative specifications for the new Opcode Super Game System.

CPU: Could be the Z84, 8 MHz + the 68000 clone from Toshiba/Hitachi
Main RAM: Least 32 Kb, or more for SGM Pro features.
Control: Memory and I/O decoders / interrupt controller.
Video: V 9958, not comfirmed.
Video: V 9990 up to 16-bits quality graphics. or Yamaha 7101
Video Out: Sony CXA 1645 The CXA encoder can be set to work in both NTSC and PAL mode, it can produce excellent picture quality, (SVHS)
Stereo Sounds: SN 76489 A, AY-3-8910 + Yamaha YMF278B aka OPL4 or YM2151 DAC, Stereo. Another option could be YM2612 (OP L, J, M)
SD card: Depending on the price, ALFAT SoC processor, 1 x SD, 2 x USB, FAT access, otherwise will AtariMax SD still be the option.
BIOS: 128Kb. flash.
Ports: 2 x DB9 (correct wired), 1 x Cartridge CV insert.
Front panel: 1 x On/Off, 1x Reset, 1 x Blue LED.
Back panel: Possibly VGA out, RCA Video out, RCA Audio out, Power in.
Expansion port: Perhaps a new compatible port, but it is not a given priority, but Eduardo likes the idea of an Ethernet port, to sharing creations online.
Case: Option is the Atari Jaguar case, maybe by: Mike Kennedy
Built in Game Manager: 128Kb. or 512Kb. of SRAM, emulates cartridge, several special functions like, cheat codes, custom palettes, screenhots, slow motion, pause, game save, etc.
Controllers: Currently no plans to deliver the unit with other Controllers, they are cool to dream about but hard to implement due to high costs.
Prototype PCB design: Revision A will be tested from March 12, 2017.
Final Super Game System release: Around 2019.

For V 9990 will all legacy video modes still be supported.

Yamaha OPL is capable of both FM and PCM in a single chip solution.

Like the Super Game Module and the Super Game Cartridge, will the new Opcode Super Game System be designed in Brazil and USA, but produced and assembled in China.

This could be the new Bios design in ColecoVision mode.


But what is the critics around our current ColecoVision in relation to the brand new Super Game System. ?

1: Power switch.- The old dry out and gives malfunctions.
2: Power supply. - The old one is big and heavy, over 30 years is a long life for such one.
3: No LED. - On your current ColecoVision are you ain't able to see about your ColecoVision is turned on or off.
4: Joysticks - Current Controllers are really awkward and designed for large hands, furthermore poor control.
5 Joystick Connections. - Awkward and difficult to access. - The new connections will probably be on the front.
6: No easy Scroll programming. Very difficult to program because Z 80 CPU not have this feature built-in. - No problem in the new Super Game System.
7: Flicker. - You can only have 2 or 3 sprites per scanline at the same time. - No problem in the new Super Game System.
8: No prober AV out. - Built for analogue TV system with the consequent noise. - Just calm down, this will be much better in the future with the VGA.
9 Monochrome sprites. -
Not possible to build a multicolor sprite ease. - But with the Opcode Super Game System will your dream as a programmer come true.
10: The Sound. - Is really good, but improved SGM Pro sound is better.

Primitive sound is maybe not the word to use as such in our current ColecoVision, believe me it's amazing what sound you actually can get out of the original SN sound chip.
But Colecovisions audio chip is limited in its frequency down to, but also numbers of channels and dissolution of music and sounds.

It was todays standard in the 80's but we are in a desperate need of an upgrade.
Some of the other consoles have improved over the years, so why not our new Super Game System.
We are thus forced to take all our critic to us, and learn from our ColecoVisions past mistakes.

But we must be serious and mostly in our efforts to attain this new Super Game System.
All previous errors as far as possible will be aligned.
The issue is time, economy and quality, so please be patient.

Q: So what is this Super Game System ?

A: The new upcomimg Super Game System from Opcode Games is an 8/16 bit gaming console.
It's a new cartridge based system that can play almost all ColecoVision games.
Understand that, this is not a new ColecoVision, it can just play your ColecoVision collection including all the Super Game capabilities.
But it is also a system where you can play new games only for this new Super Game System.
The Super Game System is not a ColecoVision and is in no way associated with RWB / Dormitus Brands.

Console status says:  First complete prototype, Revision Alpha 1 is arrived: March 12, 2017.
Games status says: Moon Patrol, Zaxxon, Ninja Kun and 1942 is under development in different stages.

A little view of some of the design for the first alpha board.
This is only a piece of the PCB.

Prototype of the new sgs alpha board...

This is the new SGS alpha board.
Click for details.

Rumors says that there is a big change that
it will be the Atari Jaguar mold for the case.

Opcode Games will produce few of the new Alpha proto board, and the first tests will show it running as a ColecoVision + SGM software.
And then afterwards concentrate on the new and improved features.

It seems like the cartridge port will be placed back on the board, and DB9 is moved from left to the front.
It looks like we back left have VGA and Phono/RCA video output, but also a DC input.
On the right side, again back, could be Audio L/R out.
The big chip is probably the 68000 clone from Toshiba/Hitachi.
Also there seems not to be an expansion port, but back on the right side could be for that.
Note: On this prototype is there not holes for the board can be mounted in a case yet.

Eduardo says about the new Opcode Super Game System:

"This isn't a Coleco product or have their involvement or the Chameleon crew involvement.
It Is a discrete chip based system, no emulated console.
It is cartridge based, runs all ColecoVision and Super Game Module games.
It is also better than a ColecoVision in every area, graphics, sound, processing.
Think of a CV2 released around 1988 and you should get a good idea of the system capabilities

Eduardo has published some of the details above.
pecifications is still secret so far, some can be removed and others can be added.
Please note that this is only suggestions for what we can expect.
