Eduardo Mello is born in Brazil and lives now in the State of America, he is already a pioneer in programming games for ColecoVision.
Eduardo sells his games via the name OpCode Games or via a publishing label.

He started with the Atari 2600, but turned quickly over to the ColecoVision.
He also have interest for Atari 7800, MSX and even NES have his interest.
"I was a big MSX user during most of the 80s"

He took fairly quickly out of that some of the games for ColecoVision was closely related to Sega SG-1000, and the first MSX machines.

Eduardo is very well with the things, and he is very thorough, and he looking at the details again and again, until he is satisfied with its outcome.
 

From Space Invaders Collection part 1.	Eduardo's first Ping-Pong in 2004. (Prototype).	Eduardo's 2nd. version in 2010. Completed WIP. beta version.

Most famous is his former site: this one. It's about Space Invaders Collection.
Eduardo's biggest hit was, and is undoubtedly Space Invaders Collection. (Space Invaders U.S and Japanese and Space Invaders Deluxe U.S and Japanese).
He started to program the game in 1999 and after 10 years including his college, was the game finally ready to meet the Cv fans all over the world.
The game sold 100 copies the first day, and have a total sale close to 200.

Eduardo threw his love and the like on Konami MSX 1 games.
One of Eduardo's first MSX attempt was Konami's Ping-Pong.
He released a partially completed prototype in 2004, this means that the game not was ready, but almost done.
There exist a few prototypes out there.
 

Sky Jaguar.		Road Fighter.

Also in 2004 started Eduardo on Sky Jaguar, and he made a playable demo.
Sky Jaguar was also finished later that year, but was not for sale.
"Sky Jaguar was the first game I got for my brand new Sharp HotBit."
Sky Jaguar did not sell so well, it was measly 18 copies on the first day via AtariAge.

At approximately the same time in 2004 began Eduardo to reprogram the MSX version Road Fighter for our ColecoVision.
It was actually a friend in Brazil who had started on the project, and Eduardo finds quickly out of the Road Fighter filled 2 kb. So there had to be optimized a lot.
It should prove to be a long affair, and Road Fighter was finally completed in February 2008.
This game sold very well.

Now was Eduardo a very busy man, and began really to get involved in the programming games for ColecoVision.
So he also made a perfect translation of the Konami game: Yie Ar Kung Fu.

  
Yie Ar Kung-Fu -and a lot of them, ready to go.

Nothing could stop him now.
He is almost a perfectionist, and a very respected programmer, and I am convinced that this is what makes Eduardo's games really cool.
Coleco Industries did not have these details in their games back in 1982 to 84 as Eduardo have now on days.
The details are what counts in the end for a game just like Eduardo's.
 

Magical Tree.

Eduardo launched a really good MSX game for ColecoVision: Magical Tree, and this game is simply fantastic.
A really good gameplay and the playing catch you.
The sound and melodies is perfect, and keeps indeed the mood up.

Also in 2004 did Eduardo started programming on a Pac-Man version for ColecoVision.
It should not just be the Pac-Man, but also Ms. Pac-Man and Pac-Man Plus should be included, and in both versions of course from Namco and Midway.

Eduardo would rather do all things on his own way.
That means programming the game, PCB's and the cartridges for his games, but some help with the graphics could be made by others.
 And with help from friends in Brazil gives the game just the final touch.

Eduardo had previously a Brazilian factory to produce its cartridge shells with the OpCode logo on the backside.

 
Production hall and some carts, the yellow one was for Pac-Man Collection.

Eduardo hired people to design his boxes, and manuals for his games.
This also includes the label, it's a very good professional quality totally.

Eduardo hired in 2007 Bryan Edewaard to produce a completely new PCB for its cartridges.
It's called MegaCart, and can in principle provide 32, 64, 128, 256, 512. and even up to 1024 Kb.
It's never been seen before, and it's first class work.

PMC was the first game ever that using the MegaCart.

Eduardo has also completed until more games, but some of them can not be used in a normal ColecoVision.
They require an extension to the ColecoVision, a so-called memory (RAM) expander.
The name for this one will be: The New Super Game Module.
Many of the programmed games by Eduardo will never see the day light as a launch, as Eduardo did not think the game is good enough for a true sale.
But games will also be programmed and sold through CollectorVision and Team Pixelboy.

An example is new converted games, and this time from Sega SG-1000
Eduardo converted at least 10 different SG-1000 games, and most of them is being published via Team Pixelboy and few for CollectorVision.com
 

Bank Panic	Star Force	Wonder Boy	Chack 'n Pop

Eduardo has almost completed Donkey Kong Arcade.
The project has been stationary for some years, but has now resumed in full-scale.
DKA is so Faithful as it can be, compared to Coleco's version from 1982.
Eduardo used the arcade version for some of his games and scale everything down 3/4 on the y axis.

DKA has it all, and that includes "How high can you get", the springs in the elevator scene, and the missing factory scene.
You got all details, also high-score and close to the original sound, all this are included in DKA.
DKA even includes a scoreboard for the 5 best players.

DKA is only for use with the ADAM Computer System or ColecoVision with the new Super Game Module.
DKA will be available in late August 2012, but not as a combined package together with the new SGM as planned.
 

Games Eduardo more or less is started on, or have plans on.
Some just not finished yet.
