I had the same feeling with Buck Rogers for Colecovision, as a child I saw one time the screenshots in a book and I wanted to play it. Recently I got the cartridge at a nice price, the game was not so fun as I thought but was a nice way to close my dream with a happy ending.

At first read I though that Mr. Do at that price would never get into my collection and then I remembered I had it already in my collection and it cost me only USD$7 for a mint loose cartridge. I think this guy throws a dice a repeats the number three times to put the price.

I also want to see what happens. Finally, Zombies in Colecovision!!!!

I don't think ports from other Z80 platforms are easy. Mostly because the video and sound chip are completely different. By example, check what Opcode has been working with Space Invaders, Pacman Collection and now Donkey Kong, it has taken years to do a faithful port of these arcade games. On my side I was able to port Zombie Near and Princess Quest to Colecovision because the video processor is identical and the audio processor is very similar. Mostly the challenge was to fit the games in 1K of RAM, the different processing of interruptions and controller handling. By example, in MSX you use both up and right arrow to jump, but in Colecovision you use the right button and move controller to right.

Hehe, then I've the rarest of all: an unique cartridge PCB with a buggy Princess Quest, only a single bug that triggers a flashing letter in a corner of the screen, it was detected in the early beta test of PCB over real hardware. I should put a label over the ROM and sign it to make it valuable ... in fact I've got two non-working Colecovision carts where I can put the PCB ... Nah! I'll desolder it to put in a ZIF socket and EPROM to do tests

I'm pretty proud of my Sector Alpha cartridge (R8) , and I have several R7, Aquattack, Artillery Duel, Galaxian, Gust Buster, It's Only Rock and Roll, Memory Manor, Oil's Well and Up'n'Down

I've saw a thread with it. I can recommend it as already I´ve bought several cartridges http://www.atariage.com/forums/topic/168225-fs-colecovision-cartridges/

I tend to write games in assembly language as I find compilers just too unoptimal. So far my convention is to use uppercase for labels that are constants, lowercase separated by underscore for functions, local labels using only point and number, and assembly code in lowercase. Functions separated, commented at start for args input/output and some info about operation. Some comments at right for important points. And of course some comments on how some function works or what reason was behind its implementation. Furthermore at the top of each source code module I like to put revision dates with comments of changes (great help to detect introduced bugs). And when a module becomes too big or it is platform independent I just separate it in something clearly named. By example for Princess Quest I've a "nucleo.asm" (core) module used both by MSX "quest.asm" and Colecovision "questc.asm" versions where I put platform dependent code.

Someone in a thread pointed to yahoo.jp as a good place to search for MSX computers/cartridges at good price. Looks good. Anyway I just searched also for Colecovision a see what I found http://page6.auctions.yahoo.co.jp/jp/auction/f111842313 Pretty strange

You can buy an USB capture box (receives composite A/V, RF, TV) and connect your SG-1000 and record the output in your PC for taking stills.

And here is the box (extracted from the latest Team Pixelboy news bulletin) Enjoy it!

As nobody else is selling another GnZ cartridge then the vendor can put any price (free market and whatever.) I'm going for popcorn, I want to see how high goes it

I'm not the most qualified person to answer that. I don't know (Pixelboy? Opcode?) But myself I've made a private Colecovision emulator and recently I've added support for SGM, mainly for testing sound and developing sound instruments over two voices (one from SN76489 and another from SGM) Piano gets a stronger bass and flute really sounds like flute. Now I've to test with some melodies

Yep, more or less in thirty years . [edit] Sorry for the misunderstanding, I'm supposing you're talking about converting your cartridge for private use in your computer (I feel like that is right) I suppose that future versions of BlueMSX or other emulator will include support, but that would be depending of emulators' authors willingness, so that could take some years.

Not really a secret, but you should write to Sander van Nunen at this email: info {at] supersoniqs [dot} com Last time he offered me very nice prices (a lot better than eBay) and he is very serious. Other worthy website is http://www.retroclasificados.com/ it's from Spain, there are a lot of MSX computers at good prices.

I'm in awe! Princess Quest art printed looks amazing. Luc, you're great! By the way, remember I'm in for other of your releases: Wonder Boy, Dragon's Lair, Thexder, Super Zaxxon and Quest for the Golden Chalice. :) My friends will be surprised to see these nice games CIB :)

It looks pretty fine and it is in its box, it's worth its price. Besides it is in your country, you don't have to pay customs/shipping from other country. I've one with a few scratches (no box/manuals) and Hang-on game, original A/V cable and two controls, Spiderman cartridge and generic power source that at somepoint I'm intending to sell for USD$40, common price for this console in Mexico.

I've to say it again Good work!

I've saw it yesterday, I thought that bfg,gamepassion was about to publish a post in Atariage. but looks like Pixelboy was faster Looks good and player moves smoothly. Only the bombs background needs polishing.

Hi Arkhan. I've saw your project pictures some weeks ago and even I put a message in karoshi.auic.es about it. Nice to know that you also are registered in Atariage. I'm the guy behind Zombie Near, Princess Quest and Mecha Eight. Most recently some MSX2 has gone in these games for 8 sprites in line and fading in/out screens. And Zombie Near and Princess Quest already have got Colecovision ports soon to be published.

And of course, Famke Janssen for Crimson Viper.

Based on the explanation it doesn't look so complicated. I'd write different values in 2000-7fff zone maybe in increments of 64 bytes and reread them for comparison. If everything is ok, then you've an ADAM. If not then activate the SGM through port $53.
