    Side by side, here are the PS3 lenses that are currently available for your PS3. If you ever decide to change the lens yourself, my best advice is to always open your PS3 first before ordering any new lens as there is no way to determine which model use which lens.

    Attention: PS3 40gb may use a different lens: LENS KES-410A or KES-410ACA (but some ps3 40gb has been found with the other lens KES-400AAA)

    The history of this SNK MVS bar top or countertop arcade cabinet can be seen HERE, a video is also available

    But what if you want to build your own, powered by MAME emulator?


    MAME stands for Multiple Arcade Machine Emulator. When used in conjunction with images of the original arcade game's ROM and disk data, MAME attempts to reproduce that game as faithfully as possible on a more modern general-purpose computer. MAME can currently emulate several thousand (more than 7000 titles) different classic arcade video games from the late 1970s through the modern era.

    This site is offering 3D view and details of 9 countertop arcade cabinet.


    Choose a layout,&160; I personally prefer layout number 5/7 as it use an LCD, has a backlight front panel.



    Search for an Used/New 15’’ inch or&160; bigger LCD screen. If you choose a bigger screen, you’ll have to adapt the size of your small cabinet.

    Use Mame

    There is a main board that allow you to use MAME in an optimized package. You can run nearly 3000 games from the past 30 years.

    PCB 3000 in 1 (2,4Ghz) for 359.00EUR
    Pcb JAMMA to cabinet / Supergun.
    From Space Invaders to Street Fighter III through metal slug series and the king of fighters find or discover such evidence of legends on one card!. This pcb is 'THE' own pcb.
    Support (among others) the Neo Geo system, CPS I, CPS II and CPS III.
    Find the complete game list HERE

    If you use the above solution, you’ll have to add a video converter CGA (15KHz) or EGA (24Khz) to VGA (31KHz).

    but nothing stop you to use an ATOM ion, or an old pc laying around, or better a real Jamma Card

    Choose a controller panels layout

    A very good site having some online controller panels layout is SlagCoin

    Connectors / joystick / buttons

    Buy the amount of buttons/ stick you need

    bouton_translucide_bleu 12 or 6 or 8 x 2 €

    Add cables and screws.

    Neo-Geo Side Art

    neoartworkgx4&160;Someone is offering&160; original size Neo-Geo stickers

    If you don’t want to bother, you can try to find the original “Neo-Geo Countertop Conversion Kit”, a very rare collector.

    Neo-Geo.Countertop.Conversion Kit&160;

    The mini cabs are made by PVG Tech, a joint venture of Jazwares, a small toy company, and Jam'ng Five, a warehouse/distro company

  • A real Neo Geo pad with a USB port

    DSC00996.JPG Bought on ebay for 5euro. this is the cheapest version of MS sidewinder you can find. 4 button upper and 2 in front.
    DSC00997.JPG Open it, and look at the circuit board. You must determine if the circuit board use a common pin (mass) that it share by all button. If this is the case, you will have no difficulties. Otherwise you must solder 2 wires for each button. It was the case here.
      Lightly sand all pins and connection under each button, if you have no common reference (mass) you need to careffully sand the 2 connection of each button
      Use a pen to mark each connection, this will avoid any mistakes durng soldering.
    DSC01000.JPG The Neo geo pad use a common circuit, now we need to join each button with 2 wires, so thee easiest way is to cut the circuit line (can be repared easily if needed afterward)
    DSC00999.JPG You need to do the same with the cross, aim is to have 2 wire going from the switch to the sidewinder board.
    DSC00998.JPG You can fix the board below the cross, there is a lot of space.
    Now just plug your new Neo Geo pad to your pc and enjoy the feelings of having a real pad for emulator.

    A Direct Pad Pro interface for a Neo Geo Pad

    I use to find his plan while browsing over internet, it has 2 shift registries and simulate a SNES pad, I use to made a lot soldering and it took me a lot of time. Another way is to use an old use SNES pas board. Attention, Direct Pad Pro has never been ported on Win2000 and WinXp and is not working! (only win98). I am now selling it for 30euro if you are interested...

  • Reverse engineering of the IPOD firmware by using a modem noise attack!

     I got an iPod for christmas. Theipodlinux project was one of the main reasons for my choice and so I started exploring the iPod as far as I was able to. I patched the bootloader and got some basic code to run but there was no way to access any hardware other than the two CPUs yet. To get the LCD, Clickwheel and the harddisk working we needed to reverse engineer the bootloader in the flashrom. But to do that we first had to find a way to get that code. Seems quite impossible without any knowlegde about the IO-Hardware but I found a solution...

    They have in fact use the internal tweeter of the IPOD to dump the result of code execution of the firmware into sound. These people have write a digital sound compression algorithm, an encoder and a decoder!!! Now 64kb of internal code can be examined!! why? just for booting LInux!!! penguin power!!!  read more here...

  • Just got my order of three Raspberry Pi 2!. Compared to the Raspberry Pi 1 it has:

    • A 900MHz quad-core ARM Cortex-A7 CPU
    • 1GB RAM

    Like the (Pi 1) Model B+, it also has:

    • 4 USB ports
    • 40 GPIO pins
    • Full HDMI port
    • Ethernet port
    • Combined 3.5mm audio jack and composite video
    • Camera interface (CSI)
    • Display interface (DSI)
    • Micro SD card slot
    • VideoCore IV 3D graphics core

    Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10! The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1.
