    I've been reverse-engineering the architecture of the "KenSingTon Vii" -- a cheap Chinese rip-off of the Wii -- with the goal of eventually emulating it on the Wii (because I'm weird like that).

    [​IMG]

    I bought one and took it apart:

    I've now dumped the ROM from the cartridge that came with it, as well as the internal ROM that is under the epoxy blob on the main PCB. It turns out that the CPU is made by SunPlus; judging by some strings we found, it's a SPG243, which is probably very similar to this chip: http://www.sunplusmm.com/products/game/g220.asp

    Does anyone know where I might get a copy of the datasheet for that chip, or some other info? The same chip seems to be popular in those "plug-and-play TV games" made by Jakks, etc (previous thread about those is here). We could particularly use some info about the sound registers of the chip.

    Even without it, Segher has made quite a bit of progress with his emulator (source available), as you can see here:

    Nah, that's not a Vii clone but just a Famiclone. The other one says it's 16 bit so maybe a SFC clone?

    Nope, it's a "unSP" architecture device, which is its own beast. See http://mcu.sunplusmcu.com/soft/mc75f2413av11.pdf -- a different microcontroller with the same instruction set.

    We can disassemble the code and emulate most of it, but are still having problems with the sound hardware, which is what I was hoping someone here might be able to help out with. :katamari:

    It looks like if part of the information about a concept design between the Xbox and the 360 was illegally given by a Microsoft employee to pay a huge poker debt to the chinese mafia, it leaked the information on the interwebs and some famiclone maker found it. Anyway the mafia tried to translate all documentation to Chinese causing the destruction of 99% of the data, so the maker had to wait until the release of 360 to understand the few low-quality remaining pics and the only paragraph that wasn't translated to Chinese. Then realized it wouldn't work and just made a plastic shell with a famiclone inside.

    Now, getting back into the topic, what called my attention from this clone is that in the website says that the controls have vibration feedback, how the hell can it be possible? Have they heavily hacked some of the games to vibrate when you get hit or something? Or the controller starts to rumble as soon as you turn on the console maybe? This kind of stuff never stops surprizing me.

    It'll probably be like other famiclones with "rumble", which rumbles whenever you press a button.

    Those pads look particularly nasty, even by famiclone standards...

    I believe, that the multigame is a vii clone, the two others are NOAC/Famiclones . since that is what I have figured along the way.
    Now I just need some kind of Danish importer... and then I check this machine out.

    It always amazes me what people think looks cool....

    I'm honestly surprised that none of them are drenched in blue LEDs... but I guess that would have cost money.

    Beats me why they can't make famiclones with the regular Famicom pads.

    I remember looking into many edutainment systems just to find one that came with regular pads, rather than these cheap PSX/Xbox style ones.

    On the plus side though, most famiclones use the same kind of pin-outs for joystick ports so most of the time you can swap controlers around on famiclones and they work just fine.

    They're trying to pretend to be more advanced. The boxes often have images from much later games, N64 and so forth.

    Yeah... the KenSingTon Vii's motherboard is tiny, so it actually has a weight inside the case to make it seem like its more powerful.

    Actually, that would be fun to make portable (considering that the board is so small)...

    FWIW, the Vii actually has bidirectional wireless communication between its shitty "Wiimote" and the big empty plastic box with a weight. As in, you get a little speaker that plays *samples* and occasionally rumbles. I was impressed.

    (The one part it's missing is the IR tracking)

    Okay, lemme try this again. I'm not looking for info on famicom clones, but rather:

    Can anyone provide me any technical info about the SunPlus unSP-series gaming chips?

    The Multigame i posted is not a famiclone. It's a 16-bit "thing".

    1 cart has 16 games and the other 6 "interactive" games.

    I posted it because it could have some similarities with the one you posted. The other were just for curiosity.

    I can delete those, if you can. Didn't want to destroy your topic. :shrug:

    Anyway, the only place for resource i found was http://www.sunplus.com/ and the one you provided.

    Also found more Wii Clones (Called Vii Sport) on Madeinchina .com

    http://www.made-in-china.com/showro...hu/China-Game-Console-Vii-Wii-Sport-Vii-.html
    From: Ecbuycn Technology Co., Ltd.

    And this one:
    http://www.made-in-china.com/china-...xkPmvbghF/VII-Sport-Game-Console-VX-002-.html
    From:E-Technical Company Ltd.

    Maybe they use Sunplus chips? Anyway, i have no idea how to get the datasheets. Hope you managed to find something.

    I remember bunnyboy over at nesdev mentioning sunplus in some thread, if that helps in anyway (probably not).
