A real Neo Geo pad with a USB port

	Bought on ebay for 5€. this is the cheapest version of MS sidewinder you can find. 4 button upper and 2 in front.
	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.
	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)
	You need to do the same with the cross, aim is to have 2 wire going from the switch to the sidewinder board.
	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 30€ if you are interested...

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

I got an iPod for christmas. The ipodlinux 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...
