    Thanks, yeah, I also want this game to see the ligh of day

    This will be my tribute to Mr. Lowe

     

    I bough a CIB PC Leisure Suit Larry just to be able to capture everything found in the original game and also the manual

    I also plan to add some stuff not found in the original game, some secrets and easter eggs

    Maybe like some homebrewers will be in the game :lol: ;) :P

    Eduardo, Luc, Daniel, PKK, Dvik/joyrex, Scott Huggins, Kevin Horton, Youki, Bfg-passion, nanochess, the Brotherhood, and the others.... Check your back! , you might be present in this game! ;)

    :). 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) :grin: :lol:

     

    Just kidding. ;)

    Ah I see... so in terms of porting from systems like the MSX and SG-1000, you already have some of the work done for you, whereas with, let's say the Game Boy (a z80 based console), you may as well just write the game from scratch.

    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.

    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.

    Mr. Do loose cart wish I could get even half the $555 the seller is asking for this.

     

    eBay Auction -- Item Number: 3209969551051?ff3=2&pub=5574883395&toolid=10001&campid=5336500554&customid=&item=320996955105&mpt=[CACHEBUSTER]

     

    I wonder what the hell people are thinking when they put something like this up for such a ridicous price. $19.99 BIN with free shipping would be a rip off but at least a person might consider it, but $555 come on!

    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. :-D

     

    I think this guy throws a dice a repeats the number three times to put the price. :P

    The funny thing about people complaining about "not enough original games" is that I hardly sell Burn Rubber copies....there is plenty left! .... Compared to Arcade games wich quickly soldout each time!

     

    Same thing happened with Armageddon

     

    Now waiting to see what will happen with Zombie Near...

    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 :grin: ... in fact I've got two non-working Colecovision carts where I can put the PCB :-D ... Nah! I'll desolder it to put in a ZIF socket and EPROM to do tests :)

    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.

    Yeah I mean basically after these guys decide to quit making these things. Someone's gotta be able to play these games another way somehow. What if Opcode only ever makes 220 units? The game devlopers themselves would probably feel they could benefit from additional sales, maybe even by porting the games directly to run on PC then sell the discs.

    I'm not the most qualified person to answer that.

    What emulator do these guys use to test the WIP games as they are being made?

    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 :)

    I can't afford one right now but don't want to miss out on the Zelda clone. Do you think in the future these SGM games will run on an emulator?

    Yep, more or less in thirty years :P.

     

    [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.

    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.
