I bought several Colecovision cartridges and everything was in great shape, also fast shipping

I've bought thirty Colecovision cartridges from him and I was absolutely delighted to see that them came fast, were packed carefully and were amazingly clean and looking as new. A+

It's pretty hard to learn programming because every person is different, but here are my suggestions: * Only one language at a time. The one that you feel most comfortable. * Start with very small games (Nim, Tic-Tac-Toe, Checkers) WITHOUT A.I. * Try to answer questions yourself (some people know this as: learn to think) * Don't leave until you get it working. * Dedicate a time everyday, same hour. * After mastering a step, put yourself new objectives. (slightly more complicated games) By the way, the "C programming language" is not good for beginners, it assumes that you know how to program, but it is necessary if you want to learn C. Go to your local library and check for the book with the tone that you most understand. In 80's and 90's magazines published programs that served as a reference to learn, but now the Internet is the resource, just search for small programs and try to understand how them work.

Oh my... I hope someday to get a loose cartridge of it for a more reasonable price.

I came to Colecovision searching for TMS9918 programming information while developing for MSX (2011, almost 29 years later) First was the challenge to make my games to work in Colecovision, then I knew I had to have one to test in the real hardware and I really liked it, so I started collecting loose cartridges. Now I've 80 cartridges, mostly standard releases, some homebrews, some repeated and of course various CIB. Maybe it is because when I was a kid I couldn't afford a game console, but certainly I'm having a lot of fun with it and it's my preferred over my other old consoles.

My favorite standard cartridges are: * Burgertime (really it's better than the arcade) * Q*Bert (very high quality for being 8K!!!) * Defender (smooth scrolling) * Gorf (I like to see it as several minigames )

I've found very helpful the explanation from tabachanker2.

Great to see this update! And of course I'm waiting for a new version of BlueMSX

I also prefer a black case.

. Just put me at the side of a pretty woman, trying to impress her "do you want to see the size of my chess program?" (side joke about my world's smallest chess program in C) or maybe a quote about Larry "hey guy! you're walking over my chess program" (a tiny stamp on floor) Just kidding.

Very well explained. I'll see if this time I code finally some Atari subroutines. Though I think my 6502 abilities are somewhat oxydized.

That's right. Besides the Game Boy allows 4-color sprites, effects by video line and scrolling with hardware aid that are hard to replicate with Coleco VDP processor.

Casually I was online! Great to see that finally Zombie Near is out!!!

I can say that after exploring carefully various sites the only way to get cheap MSX and games is to enter almost daily to the forums, the offers came up unexpectedly and the fastest one gets them. I got my MSX2+ Sony HB-F1XDJ from retroclasificados.com at a price of 200 euros. I can say that is a very nice machine, anyway I had to resolder a couple of cables of the RAM expansion someone did and recently I replaced two leaked capacitors that were muting the FM audio. Also I got a MSX1 for only USD$50 as an unexpected offer that I took immediately and included a Mopiranger cartridge with box. I had tried almost three times to get a loose Gradius cartridge before finally being able to order a Gradius, Gradius II and Vampire Killer CIB and that was because the other buyer didn't paid in time, it cost me 200 euros but I'm pretty happy with the three games and more after seeing the current eBay prices. But as everybody is saying, with these high prices is hard to think about ordering more cartridges, mostly because there are a lot of not so good games. The only way is to keep an eye in various sites. The hard thing is to have the time.

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.

meteor zone meteor disaster meteor avenger Would you give me my credit? Oh, I asked too late

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
