    Follow up on my book received on Friday.  I read the entire book this past weekend and it was a blast.  It was a fun read and it had a brief description of each game.  I would have liked more to read about each game only because I enjoyed the Coleco so much.  I thought the rating scale was decent as was the rarity scale.  

     

    I'm also glad to know that some of the rare titles are not that good.  Saves me some money in hunting them down.  lol  Overall though, I believe I have played every game in this book either in my childhood or in my search for games as an adult.  Most of the rare titles were placed on the Flashback (which I also own) and may give them a shot one day... although with some of the ratings, I'm not in such a hurry to do so.

     

    Thanks Oscar for giving the Coleco fans a fun read... next up you can do all the titles since the crash!  lol  Lots of Homebrews out there!

     

    PS - The black and white version of the book is perfectly fine for me.  I look at the screen shots and sort of see them in colour as I remember them back in the day!

     

    Thank you very much for your comments! I'm glad we agree on rarity and ratings.

     

    It's amazing what the mind can do, and actually the Lulu printing is *excellent* for the screenshots.

     

    I don't think I can do ever a homebrew version, I've missed lots of them!

    Oscar: excellent job!  having read the book I am now ready for the sequel: homebrews and protos!

     

    get cracking!  :)

     

    Thanks! I'm glad you like it! It means a lot for me.

     

    A homebrew edition would be a hard to do as I said before, because I've only a few of these (around 50 or so).

    nanochess:  Do you need to declare #c to be UNSIGNED to make this work reliably? 

    No, because the result is always positive. And let us remind that the result is 16 bits.

     

    Let us suppose FRAME reaches the value 0xfffc, then #c gets assigned 0xfffc.

     

    FRAME = $fffc    FRAME - #c = $0000

    FRAME = $fffd    FRAME - #c = $0001

    FRAME = $fffe    FRAME - #c = $0002

    FRAME = $ffff     FRAME - #c = $0003

    FRAME = $0000  FRAME - #c = $0004

    FRAME = $0001  FRAME - #c = $0005

    FRAME = $0002 FRAME - #c = $0006

    ...

    FRAME = $0006 FRAME - #c = $000a (10 decimal)

    How many color versions did you have printed?

    I think the site Lulu  prints on demand.  When you place an order , it prints and send to you.

     

    Yep, Youki is right, it's print-on-demand. If nobody wants a color edition, then Lulu doesn't print.

     

    But I prefer to say that a few copies are remaining so people hurries up to buy some books 😜

    How do open loops work in IntyBASIC?

    It means to have a main game loop (like the ones used in my book):

     

    game_loop:

        IF explosion THEN

           explosion_frame = explosion_frame + 1

           IF explosion_frame = 10 THEN

               explosion_frame = 0

           ELSE

               ... do things related to explosion...

           END IF

       END IF

       ... update sprites...

       WAIT

       ... handle game ...

       ... handle control ...

       GOTO game_loop

     

    Although if your explosion stops the game, then you are doing it right.

    Your project seems so super cool!

    Thanks! 😊

    I really want to learn more about it, but as I am a noob to ASM programming, I'm afraid for the moment it might be over my head.

     

    But I'm definitely going to delve into it more when I get a little further along.

     

    Would you say your book is for more advanced ASM programmers?

    You don't need to be an assembler programmer. But the book expects you to know hexadecimal and binary numbers. And a little C, Java or Javascript helps definitely.

     

    It's for the people that has programmed a little but wants to dive into how 8086/8088 assembler code works.

     

    The example programs are extremely small (none of the programs exceeds 500 lines) and explained step-by-step, also the processor instructions appear in the book as these are introduced.

    Hi all.

     

    After a lot of effort, with the help of @Zendocon for proofreading, and a foreword by Peter Ferrie, I've published my new book Programming Boot Sector Games both hardcover and softcover 😊 http://www.lulu.com/shop/oscar-toledo-gutierrez/programming-boot-sector-games/paperback/product-24188564.html

     

    It includes a crash course on the 8086/8088 assembler language programming, and a nice tutorial/description to all my boot sector games 😉. I think that even when some involved coding went into these, it's easier to learn using small programs and friendly text.

     

    At same time released bootBASIC (chapter 10 of the book), a BASIC language in 512 bytes https://github.com/nanochess/bootBASIC

     

    And bootOS an operating system in 512 bytes (an afterthought because the book was already in printing) to run all the boot sector games. https://github.com/nanochess/bootOS

     

    Enjoy it!

    It's better to sell in Atariage because eBay takes its juicy 10% and Paypal another 5%, besides (at least for me) you need to wait 30 days to get paid by eBay. Anyway, eBay has the advantage of auctions and the impulsive buyer (don't forget to disable 0 reputation buyers and enable the No Returns Accepted checkbox).

     

    I don't had any problems except one guy that complained about shipping time.

     

    My experiences in Atariage are far better, maybe because everyone here knows about games 😉

    Yes, is a hardcover version available? The permanence of hard vs softcover is obvious. Please consider a hardcover version.

     

    This book looks fabulous, and a treasure like it should be available in hardcover.

    I wanted to keep it economical. The hard-cover adds 10 dollars to price or so.

    Also, will a version with color screenshots / color in general be made available?

     

    One nitpick, I do not know why it was necessary to head each page with the title and copyright message. That makes the book look unprofessional, and wastes space which could have been better used. How many other books do you know that do this??!! 

     

    I'm doing a test print of a color version, but the price rises sharply. I'll put info there if I'm satisfied with the result. I did the header that way because it has been a lot of work to write each review, besides I think the font is small enough.

    Hi all.

     

    My new book ColecoVision Games Guide is now available! :) with reviews, screenshots, and trivia of every game made during the ColecoVision's commercial availability.

     

    I'm particularly proud of having scanned each box in my collection for this book. Wasn't an easy task to write a review for each game.

     

    Foreword contributed graciously by Jennell Jaquays. Special thanks to mthompson and Ikrananka for doing proofreading and facts revision.

     

    B&W edition:

    I got a El Gato Eyetv-Hybrid for Mac but couldn't synchro via RF, the Intellivision screen appears in gray for a brief moment and then all synchro is lost.

     

    I thought all was lost, but saw the tip in the first post for passing it thru a VCR and using the composite output. I can do an attempt :)
