    A good tip someone suggested is the power/data cables are much thicker than the straight power cables - help me out! Hopefully that might help find/ordering a suitable one.

    I hate how there’s at least two types of cables that look the same and some dozen different connectors. It’s ridiculous.

    I saw your post and tried that 😢

    You also have to have the cart plugged in by USB when you open the program. If you insert the usb while the program is open, it won't recognize it. Also, try uninstalling the program and install it in the root of the C:\ drive rather than the x86 program files folder. The program file folders have peculiar security blocks.

    I'm going slightly crazy, trying to update the bios but despite downloading the drivers my cart is not detected. Tried on two windows laptops .
    Looks like I'm stuck on .93 which thankfully is stable for me 

    I had to use a different usb cable as the first one did not allow me to recognize the cart

    Thanks to the information provided by John Harvey for the below details...

     

    =============================================================

    Error codes

    While disassembling the code, I found some of the error codes.
    Note that the error code is sent to the "Yuk face" routine as a hex code on the Y-register, which
    is then translated.  $0 thru $9 translate to 0 thru 9, and $A translates to "X".

     

    Here is the list that I've accumulated:

     

    01 - Failure to debounce either the reset switch or select switch
    02 - RAM $0480 - $04FF error
    03 - Diagnostic cart is running on a 2600 (cannot store to $2000)
    04 - Status flags or stack error
    05 - Failure of a PIA Timer
    06 - Control port failure; occurs if not using proper diagnostic plugs or if the SWCHA ports are
         broken
    07 - INPT failure; occurs if not using proper diagnostic plugs or if there is a failure in one of
         the INPT registers on the PIA
    08 - diagnostic plug failure (if I remember right, this has to do with not having the 47 k-ohm
         resistors on the plugs.  I will re-investigate later.
    11 - RAM $0140 - $01FF error
    12 - RAM $0040 - $00FF error
    14 - $FFF9 error-- Either the left nibble at $FFF9 does not contain a valid bank size (i.e. > 48K)
         or the right nibble isn't 7.

     

    Error codes in the code that I haven't figured out (yet):

     

    1) Numeric codes:
    X0, X1, X2, X3, and X4 -- I found these codes in the following code segment:

     

    ;;;;;;;;; START CODE ;;;;;;;;;;;;;;;;;;

    LF884:
         LDA    $F88B,Y  ; $B9,$8B,$F8
         TAY             ; $A8
         JMP    $F026

     

    LF88B: ; SIX error codes used by F884.
         dc.b   $A4      ; will display "X4"
         dc.b   $A1      ; will display "X1
         dc.b   $A2      ; will display "X2
         dc.b   $A0      ; will display "X0
         dc.b   $A3      ; will display "X3
         dc.b   $03      ; will display "03

     

    ;;;;;;;;;;; END CODE ;;;;;;;;;;;;;;;;;;


    Note that there are also other errors that are not caught with an "error code".  For example,
    on the first screen where it says "7800 PRO SYSTEM DIAGNOSTIC TEST VERSION    1:00",
    you can also somehow trigger text that says "       BAD!!!!!".
    This is found at $EB87, the third chunk of character map data, to be stored at $191E.

    =============================================================

    @Mitch too provided some insight and results experience with "X4" as well:

     

    X4 - I got this error when I installed the standard NTSC OS in a PAL machine. I also
         got it once when I hit a console button at the color adjustment screen.

    =============================================================

     

    The Diagnostic Cart is a part of Trebors 7800 ROM PROPack.  Posting the image here for convenience as well for anyone else that would like to leverage it:

    Want your own copy?  Best Electronics has it... image.png.1011d863935e6f85a4b2c59bfe63d385.png 

     

    @Swami Did you opt for the Universal NTSC/PAL BIOS with built-in Asteroids mod ("7800 Euro Operating System Upgrade") for your Best 7800 console?  The cartridge itself will not run at all on such a unit (I have both the cart and a Best Electronics mod with OS upgrade), but just the ROM image itself on a 'flash cart', I have not tried.

    Sorry, by "best" I meant the most compatible of my three 7800s. It's just a random X series 7800 I bought off of eBay.

    I just tried out my least previous Concerto compatible 7800 A1 series 7800. It either does not load the Arkanoid demo in Trbor's Pro Pack or crashes after choosing the joypad. I ran the utility cart, which once failed to load and once crashed after the internal RAM check, although the RAM check all passed. Also, external RAM passed. Cart integrity test showed three out of four blocks with dots rather than the block at the verey end of the F0 line, although I got the same with my best 7800. Everything else seems typical of my best 7800. Also, with the Diagnostic cart, I got a frowny face with X4 under it???

    Not that I'm aware of, although I wouldn't say any of those things are completely off the table.

     

    A bluetooth controller adapter is not a ridiculous idea for homebrewer to make, once the Amico controllers come out. I've seen it done for the Atari 2600, but only for the 2600 compatible controllers.

    Up for sale are my brand new Atari 7800 cartridge shells. I took the liberty of making some in a variety of colors I like however since I own the mold I can make other colors as well. These are made in the USA. 

     

    The shells are designed off the original however do not feature the latches and instead have two pegs at the end to keep the two halves attached. Seems to work fairly well on my testing. These should fit most PCB boards however there seems to be a variety of boards used so I cannot guarantee 100% compatibility. They worked with the original PCB boards I tried. 

     

    They are $5.99 each plus shipping and come with the center screw. These are in hand and ready to ship. Website To Order From

     

    I also own a mold for Atari Jaguar shells and Sega Genesis shells if anyone needs either of these. They are both USA molds as well. 

     

     

     

     

     

     

     

     

    Do these hold together without the screw like the ones with the 4 snap in place tabs? Thanks.

    I'm not sure where the cutoff is for 2600 complexity or if we will get Encore level compatibility, but wwith 0.95 Space Rocks and Draconian did not load, along with other complex 2600 games. For 7800, Milli and Molly loads and has some sort of sound effects but is all scrambled, Pac Man Collection 40th Anniv has no sound, but BBCQ still plays with POKEY sound.

    I have one Atari branded POKEY chip from Best Electronics with original part number C012294 and two I got from somewhere with "Philippines" on them with part number C012294B. Any idea if they behave differently? I seem to recall having better luck with the Atari branded one, but it was a long time ago, so, I may have accidently used different 7800s with each. It could be something I check unless it is known they are functionally identical and a waste of time.

    I received my Concerto on Saturday and tested it a little. With the Concerto from the first run, I grabbed up five 7800s of different major revisions and kept the three that worked best, to varying degrees. The one I started with here worked perfectly with the first run Concerto if it made it to the intro screen, so, no surprise, it works with all the 7800 games I tried like BBCQ (with POKEY!)  and Popeye demo. It also worked with the simpler 2600 games and homebrews, but only less complex than those like Bosconian, which failed to load. I can try some more tomorrow and a different 7800. I did experience a menu freeze and a high pitch noise after power cycle once each.

     

    Used 0.93 and I used a SanDisk Class 4 32GB SDHC card with no issues.

    Just reserved mine.

    3 multicarts down (Intellivison, 2600 and 7800), only 4 to go (Colecovision, 5200, N64 and Genesis) -- until I start making googly-eyes at the O2 and TI-99/4A again, or finally get a Vectrex. 

     

    Maybe I should start a GoFundMe page! :D

    Hi folks!


    I have posted on one of my blogs about the バンダイてれびっこ (Bandai Terebikko) different two models and other information.

    You can view the post here: https://discreteconsoles.blogspot.com/2020/12/the-bandai-terebikko-video.html


    But mostly, after years of research i have made a list of all the VHS-tapes "games" that was released for the Terebikko.

    On Wikipedia, there is only 9 title listed and on Wikipedia Japan, it has 19 titles listed but in reality, there is 33 titles (+ one

    Sample Video tape) that was released for the Terebikko.

     

    The list is uploaded on Archive.org here: https://archive.org/download/bandai-terebikko/Bandai Terebikko List (dec-2020)(by Sly DC).xlsx

    and is also in attachment with this post (just in case).

     

    And you can also view/download some other files here: https://archive.org/details/bandai-terebikko

     

    The next post will be about the specifications of the Terebikko so hoping this will help out the emulation community and to preserve

    digitally the console and games, and also maybe see a homebrew for it ?!

     

    Have fun, folks!

    No, I don't have this, but I have been loving checking out and often buying plug and play devices you have to search for in Japanese on the Japanese websites. Of course, it would be easier if I could get them in the USA, to save on postage and travel bans, like going on now. Hopefully, MAME can start doing VCR tape "Rom" console emulation soon.

     

    I've bought a few that have a 4-5 year old kid playing on the cover ... not sure I should admit that. LOL!

    I just replaced all the capacitors in the Console5 refresh kit, all with the other Console5 parts, ICs and power switch mentioned above along with composite mod and it made no real difference. The white flash at power on is gone now. There is just a very slight flicker, a "pop" sound from the TV and a low hum on power on. 

     

    Given what is replaced, any likely components or voltages I should check?

    Hi all,

    I got a Sears light sixer in a lot with a 7800 and have never got any response out of it even after many parts replacements. The screen is black whether the atari is hooked up and on with cart or not hooked up at all.  Finally did a composite mod, now I get a white flicker with an audio "pop" when I turn the power switch on the SLS off or on and a low hum when it is on. I also get lots of white hazy horizontal bands and white flickering when slowly pulling the video RCA cable out of its composite connection.

     

    BTW, this is the first console I've tried to fix with anything non-trivial or bring back. Also, the first composite mod I installed myself, but everything looks right.

     

    What else I did before:

     

    Cleaned cart port with 91% IPA and lint-free cloth.

    Replaced all four IC chips

    Replaced power switch, power jack, power regulator and the large cylindrical capacitor on the switchboard with the Console5 refresh kit.

     

    I have some capacitors, diodes and a resistor in the refresh kit, but I can't make heads or tails of where the capacitors go and, from the Console5 Wiki, it sounds like the diodes and resistors may not need replacing in a light sixer. Also, it sounds like a blown small capacitor wouldn't take out both video and audio.

     

    I've been trying with a Defender cart I used in the cart port cleaning process as well as 

     

    Anyone have any educated guesses what might be keeping my Sears Light Sixer from getting picture or game sound?

     

    Thanks!

    The last job my dad worked, was as a contractor for Goodyear, in China.  His translator called him "grandpa ATM" because he always bought her food (lunch, dinner, etc.)  She would also ask him "grandpa ATM, what means nipple?", because the guys in the factory would joke.  He would only answer "I cannot tell you that - look on the blueprint".

    ATM has its own issues. 🤪

    I’m just curious. I know firmware has been done for the MISTer to play problematic A2600 games like Pitfall 2 on its A2600 core last April.  Is there a significant barrier to implementing this on the Phoenix’s core or is it a lack of time to devote to that core. I ask because I seem to remember the conversion from MISTer to Phoenix was supposed to be fairly straightforward.
