There are some good levels in Buck Rogers, but the enemies look like pasted over the game, too easy, just moving left/right and shooting so fast as you can. I really expected more from this game.

Someone has noticed that Charlie Sheen and Owen Wilson are very old? Of course finally Bison could trap Ryu because Ryu is using a cane to walk . But anyway if old actors are being called , I suggest Milla Jovovich for Cammy and ComputerSpaceFan is right with Bruce Campbell for Bison. Sorry I'm falling from by chair because a lot of laughs xD xD

For the more technical involved, a small discussion of how I did the scroll in Princess Quest. In the highest resolution VDP mode (mode 2) the screen as you see is composed of 8x8 tiles, there is a frame of 32 columns by 24 rows, each eight rows can have 256 different tiles. In order to do smooth scroll, you should define tiles shifted by pixel AND combined with following tile (by example, 6 pixels of tile plus 2 pixels of following tile) For fast update you change the screen (32x20 tile indexes or so) each two frames so you leave one frame for internal game logic (no way to do it updating pixels, that would be 4K-6K bytes, and VDP is very slow) Need to say that VDP limits colors roughly and you should play tricks to combine different colors, like leaving at least 8 pixels space between tiles of different color. If your game uses less graphics, you can redefine a small number of tiles continuosly. And of course I saved some "untouched" tiles to draw letters for score, record, energy and lifes.

I believe that MSX/SMS compatibility is not a good idea. I prefer certainly to see ports of selected games from all platforms instead of "embedding"/"limitation to" an MSX/SMS inside a Colecovision. As jblenke says, I prefer enhancement in video/sound/memory along backward compatibility. Video/sound can get enhancements to ease development of future games or ports from other platforms. Just my 2 cents.

It's awesome! Thanks!

Two times has happened me this: "You already have voted in this poll". But I didn't filled it before ???. My suggestion would be a compatible Colecovision PCB board (I'm thinking that someday my CV will fail) with 24K of RAM, 2x or 4x speed processor, enhanced video outputs (S-Video/Components, HDMI), enhanced video processor (V9958 or F18A capabilites) and enhanced sound processor (SGM and/or FM). I believe that a way to reduce costs is to use an FPGA (processor+video+sound+memory), as supplies of old chips are becoming rare and oxydized. Esentially most of PCB would be unused, and it could resort to using a single 5V+ power supply module that is becoming very common. In case of a redesign of case, I would like very much to see a small-size Colecovision in the style of Atari Flashback but with the cartridge input and with slightly bigger joysticks and smaller keypads.

Wow! I'm impressed and also by the space used by these machines. This remembers me I've the core of a Street Fighter 2 arcade machine that I don't have tested and the working boards of a Jackson 7 (Zaxxon's arcade bootleg)

I used to had an Atari 2600 Jr but a friend wanted it so I sold it. Now I've an incomplete black Atari 2600 (no joysticks, no power source), but I'm using the Expansion Module #1 of my Colecovision, so there is no problem. Besides I've got almost by accident a Sega Master System, a MSX, a Sony MSX2+ and a functional Atari Flashback 2 that I got for USD$0.80 (looks like the owner didn't noted that the power source was inverted and not from Atari, fortunately the Flashback was not burned.) I have almost forty Atari cartridges, seventy Coleco cartridges, one SMS cart and one for MSX.

You're right. Ms Pacman was clearly superior and even fun. Every time I put Pac-Man on my Atari 2600 I cannot understand how Atari could leave it out the door without polishing it a little more!

Congratulations! I don't know the other 159, but I'm dancing on the ceiling to celebrate that the Super Game Module will come soon . And of course I'm in for Donkey Kong Arcade.

Sounds a reasonable price given that it works and it includes a lot of things. Anyway you can negotiate towards $100 as NIAD has pointed before, maybe $120.

I can strongly recommend it as today I've received a lot of cartridges in excellent state

I just have received a lot of Colecovision cartridges from Mumbai and them look awesome, almost new :) Excellent service and +1 for quality.

I second that. Recently I've got three CIB MSX games from Europe that are hard to find (Gradius , Gradius II and Vampire Killer ) and I had to pay 200 euros including shipping. eBay is driving prices very high .

In fact I've saw several barcode readers with PS/2 keyboard interface that indeed share the cable with a common PC keyboard. So if someone can develop an interface for Colecovision to use a PS/2 keyboard then the same could be easily used for a barcode reader.

You're doing a very nice work!

Payment sent!

Just I've found Colecoville http://www.tomheroes.com/Video%20Games%20FS/video%20games/coleco/coleco.htm

If it's for testing your games in a real Colecovision, I'd suggest strongly to get an Atarimax Ultimate Colecovision SD cartridge. (check http://www.atarimax.com) This way you can load your programs directly in the SD memory and then plug it in the Atarimax cartridge, it's faster than programming/erasing EPROM and you don't have to solder. Also is pretty difficult to insert an alone PCB. Besides Atarimax is currently including two games from Collectorvision: Mr. Chin and Mario Brothers.

Really?, retroillucid crosses the street to deliver to Pixelboy? that's fun

Thank you! About difficulty screen I mean to center everything as a whole to not disalign numbers. Really I'd prefer to push a button to continue instead of reset. In my setup, I've my Colecovision near my TV and I'm sitting in a chair, so I have to get up to push the reset button. Just my 2 cents

Welcome to the forums. You'll need to insert an Atari 2600 cartridge in the expansion module #1. Otherwise you get only a blank screen.

It's not really a new thing. My games Princess Quest (MSX/Colecovision) and Mecha Eight (MSX) integrate random appearance of enemies so the player does not get bored with same order each time. The random counter is active all the time while the title screen/story runs, so when the player press the start button the seed is always different. And ability to redesign levels on the fly is still in early stages, as human creativity is what makes them challenging/surprising/beautiful.

I can confirm that I've seen again the line bug, I didn't take a picture and now I cannot replicate it! I made two "towers" in the bottom part of screen and then I was making a left bump in the corner of right tower and the horizontal line appeared between the two towers. I think I was changing my mind on direction and did a brusque movement in the last moment because the crawling guy was coming towards me. By the way, I think it would be very appreciated a way to reenter game after losing without pressing reset. Also the difficulty selection screen should be centered just to keep aesthetics.
