More Sega Channel prototypes dumped.

  1. Oh, my bad. "Dyna Brothers 2 Special" and "Game no Kanzume Otokuyou", respectively.

    I tend to be out of touch with current web design fads, which is part of why Satellablog is kinda cumbersome and only "organized" chronologically speaking. Most folks tend to go for Wikis now. I don't really know what I can recommend to you web-wise, but it might be a good idea to keep this kind of info in an Excel chart much like how No-Intro handles undumped lists.

    Thanks. The idea is that I feel the wiki system isn't particularly well suited to merely collecting data, which is what we need to do for Sega Channel =P Wikis are good for presenting information, and we have definitely been doing that with the information we've collected.

    Still not great, but better than it was before.

    HA! Sega of Japan's Virtual Console site gives us some confirmation as to a handful of titles:

    http://vc.sega.jp/vc_ewj/ Earthworm Jim
    http://vc.sega.jp/vc_pitfall/ Pitfall: The Mayan Adventure
    The confirmation is the text "本作はメガドライブ版でのパッケージ販売は日本ではされておりませんでしたが、ケーブルテレビ・ゲーム配信サービス「セガチャンネル」で楽しむことができました。" (The Megadrive package for the original game wasn't sold in Japan, but it could be played on the cable TV game broadcast service "Sega Channel"; translation provided by GlitterBerri)

    http://vc.sega.jp/vc_ewj2/ Earthworm Jim 2
    http://vc.sega.jp/vc_eccojr/ Ecco Jr.
    本作は日本でのパッケージ販売はされておりませんでしたが、ケーブルテレビ・ゲーム配信サービス「セガチャンネル」で楽しむことができました。 (same thing, but without "Mega Drive version")
     
  5. Just for the sake of checking, has anyone tried ripping the Japanese Virtual Console versions of those in the off-chance they're actually the JP Sega Channel builds rather than just the US retails given to JP folks?

    If they are the US retails then this is the first time they're being given to a JP audience. Both Earthworm Jim games were never released on the Megadrive in Japan. Only one that made it was the SNES version of the first one.

    And the Saturn version of the second game (published by Takara). But this shows that they were also released on Sega Channel, so...

    Interesting trivia: Playmates Interactive released at least one Toshinden game overseas (they were made by Takara).

    Finally, found some details about the UK Sega Channel service

    you can all sleep well at night knowing that Barney's Hide & Seek Game made it to Europe after all!

    Interesting, I don't think this has ever been documented before.

    So what this is saying is whatever the main terminal was that was the source of all the data that was transmitted across Sega Channel, it all came off of a single CD? :o

    Now the question is do these CDs still exist anywhere.

    I actually remember reading this article. Really should get back around to indexing those MMS mags.

    Tried running it in my laseractive - had to dismantle it to get it to fit. Nothing happened, but most likely because I don't have any power plugged into it. Says it requires a 10V input, but I could only find 9V and 12V universal power packs when I had a look today.

    Tried plugging it into my tototek writer and didn't get anything either. Not sure if it's safe to try it again when I find a suitable replacement power pack with the additional voltage running through it.

    Chip spec: (note: for the NEC chips, change the first D to uPD or add a uPD at the beginning if absent before searching)

    back, going from top to bottom, right to left
    NEC D23C4000SCZ - 512KB ROM
    BR6265 F-10LL - 8KB SRAM
    Hyundai HY62256ALLJ-10 - 32KB SRAM; there's one on the front for a total of 64KB
    nondescript chip marked "HC10 9319Y7" (not the name of a chip)
    Microchip PIC16C54-RC/P - a PIC microcontroller, probably used for controlling the modem hardware
    Kyocera HC1-TSE - 32Mhz clock (provides timing for the modem hardware, I guess)
    "SB"? 3090C - <GerbilSoft> seemed to be a 1.8V hi-current regulator
    NEC D65650GDE67 - "CMOS-6/6A/6V/6X 1.0-MICRON CMOS GATE ARRAYS" - some gate array with 21,120 gates
    4x NEC 424400-70 - total 2MB (4x 512KB) DRAM

    front, going from top to bottom, right to left
    Motorola MC13055D - <GerbilSoft> wideband FSK receiver
    another Hyundai HY62256ALLJ-10
    some nondescript chip next to the Hyundai HY62256ALLJ-10
    some nondescript chip underneath the battery
    three more small nondescript chips next to D51, D52, and D53
    another nondescript chip next to D52
    2x 22 16T - no clue
    2x Hitachi HM514800AJ7 - total 1MB (2x 512KB) DRAM

    So clearly the ROM would need to be dumped, but that there's battery-backed SRAM in there suggests a possibility... we would need to figure out which of the SRAM chips it is and dump that (honestly though, I would dump everything, just to be safe)...

    Beautiful screenshot, but may I trouble you for a clearer picture of the front and the back of the cart?

    74hc10 triple three-input NAND gate.

    (Also probably unnecessary but in my ideal situation I would also have that PIC chip dumped... unless there is a reason not to? "PIC cannot be dumped easily" is not a valid reason here)

    So is it safer for me to pass this on to someone with experience, or should I get a 10V power adapter and plug it in and see what happens?

    Yup, those pictures are perfect. Can anyone look up the barcode?

    If you try the machine yourself, pay attention to the polarity of the power adaptor plug!
