    I was probably playing one handed and holding my phone, I don't actually remember. I do remember being giddy about being getting to play them. 😅 But I will vouch that it's playable and didn't freeze or glitch out.

    I was holding my phone and playing with one hand but I had a completely different experience.  Giggity😜

    This is a special spot in the Venn Diagram: a holy grail of Vintage gaming/ColecoVision collectors AND a He-Man item.  I occasionally post on he-man.org because I grew up in the period and have nostalgia for that franchise in particular as I was a fan as a kid, and let me tell you, if you are unfamiliar, that He-Man collectors are another breed.  That stuff goes for INSANE amounts of money, Star Wars level at times.

    Hey, to each his own....If you have $3100 smackers for a single game then you are a better man than I

    It is hard to take good quality video and play the game at the same time.

     

    The pictures in the auction were taken last week using the board that is for sale. It takes more than five minutes to get to the Skeletor fight and I am too rusty to get through the fireballs easily. The board is packed already, along with a flash drive with ROM dumps of all three prototypes (including the one at NVM which does not seem to be playable).

    I know I don't have a track record with the Colecovision people, but I think the Intellivision guys will vouch for me.

    TNX.  I was not aware that there were 3 rom dumps.

    There IS a Skeletor level then to where the game will cycle through to continue like the Intellivision?
    Also how does the title music compare to the Intell or is it uniquely Colecovision.
    Bidding is almost over so I need to know asap.

    And I respect your opinion and do agree with a lot of what you say, but unfortunately the way things will progress is the way they have been laid out by the seller and that is 200% their right.

     

    You strike me as someone that doesn’t play Texas Hold’em let alone Ken Uston Blackjack / Poker. 🧐

    Well no doubt the seller will be satisfied with whatever he makes so I guess I am out.

    I was ready to go to 2k for a working game but that has not been proven to my satisfaction.

    In situations such as these, less is more if you are the seller. With that said, don’t hold your breath waiting for further game play video(s) which IS NOT a knock against the seller. However, further game play videos after the sale would be appreciated so everyone:

     

    - gets a chance to enjoy a good view of the game in case it ends up in the hands of a private collector.

     

    - knows ahead of time what a possible physical release will play like and how complete or incomplete it may be.

     

    I appreciate that, however I can not in good conscious dish out 2 grand for what may be a dead set of eproms and it would only take 5 minutes of someones time especially when everyone has a cell phone with ultra HD quality these days.

     

    It is also not an absurd request either.

    What collector in his right mind would pay top dollar for something you don't get to touch, watch in action or even play in this case until after you buy it.

     

    But to each his own and I respect your opinion.

    It will be sent insured, with signature required.

    I, like everyone else, am extremely interested despite my sometimes sarcastic posts.

     

    I will not disclose what my max bid may be but I will say that all depends.

    Guaranteed to work to some degree and I would like to see a video of game play from title screen all the way to  entering the castle.  I would like to see the fight with Skeletor, movements of the characters and such.

    This rom may surpass $2,000 as far as bids and this is a requirement of my participation.

    That's TMS9900 assembly language.  If you used the TMS9928/29/18 in a system with a TMS9900 microprocessor, that is the code that the microprocessor would run for those demos.

     

    Colecovision has a Z80 instead.  Colecovision's BIOS, Z80 code, has some routines to program the TMS9928 and support games.

     

    But none of that is stored within the TMS9928, regardless of architecture.  CV stores its routines within the ROM chip.  There is fully commented source listing of the CV ROM program and its support functions in the ColecoVision Programmer's Reference.

     

    If your aim is to figure out how to program the chip in your own hardware, then study the data book for the 9928/29/18.  It tells you what data to send where, and when.  If you familiarize yourself with TMS9900 assembly language, you can also see how their example program performs those feats.  Just note, however, that the TMS9928 does not decode address lines, so it's up to your hardware where in the address space you put it, and you need to build the decoding circuitry to activate it only on the right addresses.

    I got the rest but my thinking that there was a rudimentary type of bios like programing a pic chip but hey, I learned something new.

     

    My next question is what's up with the external video signal on the Colecovision and why hasn't anyone modified the system to piggy back.

     

    I usually ask myself these things after a couple shots of scotch.

    The 9928 is just a graphics chip.  No BIOS.  It does need 8 RAM chips though.

    Not to argue with you but understand.

    I have toyed with and become fairly good at programing the Colecovision without knowing 100% every nut and bolt so this is my own learning.

     

    I understand the functionality of how to get what I want out of the chip but same as the Colecovision itself, not every signal on the pin.

     

    So, this is in the TI Programing manual itself.

    Is this just some example code then for a generic assembly code.

    I know this is premature....That's what she said....

     

    But is there any plans to set the screen mode to 40 column mode.

    It would be interesting to see how far one could go with the other modes.

     

    I honestly understand that this would be going way off the reservation but I thought I would at least bring up the subject.

    If you did that then there would be the multicolor mode ect....

    Technical question that needs insider info.

     

    I have several versions of the TI 9928 book including an original I received in 1984 just by calling Texas Instrument.

     

    The way I understand it is the Chip itself has a basic type of BIOS.

    I also understand that this is locked inside the Colecovision.

     

    However, a...Could a jumper unlock it (doubtful)

    but b...

    Is this bios a standard generic bios or one written for the Colecovision environment itself.

     

    Knowing a bit about chips that most of these are write once but some if you add voltage on certain pins they can be written to.

     

    I know this is above a lot of peoples pay grade but hopefully one of you knows just enough that may lead to more information.

    Maybe something Howard Eglowstein can answer if he pokes his head around here on occasion.

    I know he does over on the ADAM Facebook page.

    Version 1.0.7666.38689 released.

     

    - Fixed crash on Full Screen Editor when you move the cursor around quickly.

    - Added buttons to move Screen layouts Up, Down, Left and Right (needed it when I was working on Kangaroo :)).

     

    More changes soon!

    So you can move screen layouts up and down.

     

    I will check this out but how about being able to create screens larger than 756 tiles.

    That way you can display your Kangaroo map all at one time.

     

    I am thinking how Haunted House moves or maybe that Amiga Pinball game.  Pinball Fantasies?

    Thanks Youki

    Working out the kinks with the mines was a huge undertaking given the limits of the Colecovision memory.

    The current version most of those kinks have been worked out.

    When a round gets stuck then you can not shoot is part of the design (sort of)

    To be fair in the game I made sure that you can only shoot one round at a time and in the case of buggy v3.5 if the one round is in limbo you can not fire again.

     

    The discovery of programing:

    To save space in Assembly I used many of the same routines and variables.  I was always conscious of the 32k limit with the address space because I am dealing with 3 games in 1.

    So I write things in long hand then optimize to get the space I need.  In this case it was reusing everything.

    I found out early on that every animated object in this world needed it's own moving routine and variable because in the case of the round it was so tied to the tank that if the tank changed direction the round would also go in that direction.

    It produced interesting effects but hardly produced a game.

    Then with two players you needed twice the amount so that is 4 sets of routines.

    With 3 games then that is 12 sets of routines as you may start speculating while pulling your hair out.

     

    The movement of the tanks are unique to the original game which makes it look like it is stuttering and even that was an interesting exercise to figure out because that is not normal movement for sprites but it eventually all came together.

     

    Did you try the live tile feature yet?

    To the fans I wanted to know if it was cool or just a gimmick because it is not something seen in any Coleco game I am aware of.  Of course it is 1 screen for two players then only player one can choose the setup.

    Maybe I should just put this in the menu for two players and keep it in the one player version as live.

     

    I have tested this on an emulator to make sure both tanks fire and move smoothly as far as what the system can handle.

    It works with my real ADAM but I have had feedback that some of our games are not working on their setups so if you have the capability of testing it on a real one please let me know the result.

    Here is an early version of the Tripplin Game (Tripple-Trippin) FROM SCRATCH (C) 2020

    Will be 3 classic games from the 80's

     

    v3.5 mind you I am on v19 working on bugs and polish.  This plus the 2 other games built into later revisions of this rom.  If I gave you v19 that would give away too much of the mystique.

     

    So, I wanted to get your input.

    If it works on real equipment because this seems to be an issue with our games right now.

    Speed, stuttering, NTSC/EU if you can manage it.

     

    There are no menus, no skill levels to set but if you press 1, 2 or 3 on keypad #1 during game play you activate Live Tiles (tm)

     

    I have worked out the mines blowing up each other and I am not sure about everything that works and not on this version.

    Shooting mines makes the score go haywire in this early bugged release.

    2 players are working.  Shooting each other has been disabled.

    No sound or music.

     

    The play field is 100% random when the menu system is running because the seed value changes while waiting for you to select a game.  In this version it jumps strait to the game for testing purposes so the mines stay the same after each reset.

     

    But, here you go for now.

    100% Assembly Language

    6000 lines of hand typed Code

    Name one prototype we didn't made available publicly?

      

    Last year, we've released the rom file for Pink Panther
    We even paid to rework Math Quest so it can be played on ColecoVision 


    Energy Quiz will get release publicly, just be patient, it's only a matter of time

     

    Point I am trying to make is that people have to recoup the thousands paid for so it will not be anytime soon for free.

     

    I guess I can always word things better.

     

    As in, invest your money into paying off debt and if you want to buy one of these prototypes then do a goFundMe or hook up with a bunch of friends.

     

    Believe me, if I wasn't taking a break for the holidays I wouldn't be commenting and more programing.

    My grandson and daughter left yesterday and Monday is back to work.

     

    Then again, my buds want to take me deer hunting to break in my new AR

    I can tell you this
    If CollectorVision get this game, we'll make the rom file available to all the CV fans just like all other prototypes we got  :)

    Yeah....still waiting on that Energy Quiz rom...

    If this sells for a couple thousand we may be waiting another 30 years for it to be shared.

     

    Until then I am fine with my intellivsion version to bring me memories.

     

    The reality is you will never own the original without winning this bid and only a few select friends will own a copy.

    So your options are pay through the nose for a winning bid or pay through the nose for a copy.

    Then again there is no reason why you can't program your own version.

     

    Even if you buy the thing who knows what issues you will have to go through just to make boxes and resell copies.

    You may not be legally allowed to which you will have to sell it as a collectors one of a kind, after you make your backup like everyone else has of course, then try to recoup your winning bid.

     

    Personally, I would recommend that unless you are middle aged and retired to use your earnings paying off credit cards, school loans and your mortgage if you have one because video games are not an investment.
