UPDATE: Knocked out one of my last mods, a Mega-Modded Sega Nomad! It was pretty sweet (too bad I couldn't keep it) with a 1-player controller port, 50/60hz mod, JP/US mod, and a dual overclock (10Mhz and 12Mhz) mod!

Zach,
You absolutely rock!!! I am absolutely LOVING my Sega Nomad on steroids and I have to say, I am extremely impressed with the results. Where other console modders (OSG, etc.) wouldn't even consider touching the Nomad upon request, Zach went above and beyond on this thing and rose to the challenge.
I haven't read anyone else having modded a Sega Nomad before, so enjoy! The Nomad is and has always been my favorite console.
-------------------------------------------------------------
List of mods performed:
1) Overclock settings at 2 speeds: Mild OC of 32% @ 10 mhz // Moderate OC of 58% @ 12mhz
Every game I have works well and rock solid stable with little to no noticeable slowdown anymore @ 10mhz (sonic, general chaos, samurai shodown, etc). 12mhz was required to eliminate nasty, heavy, slowdown in games like viewpoint and lightening force. I have to say, I'm going to need to get used to dying a lot more in shooters.

I also have the option to disable overclocking altogether and run at stock speeds of 7.67mhz.
Left switch = ON/OFF // Right switch = 10mhz/12mhz
2) Japan NTSC Lockout Bypass - Press and hold A during bootup of Japanese carts to bypass lockout. Japanese carts just BARELY fit the Nomad's cart slot and doesn't require any filing... whew

3) 50/60/PAL Lockout Bypass - Press and hold MODE during bootup of PAL carts to bypass lockout.
4) And a first for the Sega Nomad (at least that I'm aware of) Controller 1 port input!!!: Unrestricted use of ANY controller for player 1 (to substitute the onboard gamepad and buttons) - Sega Arcade Power Stick, Sega's flight stick, Sega Mouse, etc!!
Onboard gamepad and buttons automatically disable with the connection of a controller in port 1.
Impossible for the Nomad before was 4 player mode with EA titles requiring the use of both controller ports 1 and 2. This is now made possible with the addition of the player 1 input port. 4 player general chaos on the Nomad anyone?

5) S-Video Output: Ok this one isn't a mod, but I recently acquired a Mega XMD! S-video for the Nomad is a piece of cake! Zach offered to mod S-video output right into the Nomad, but I wanted to have an S-video solution for my CDX or MD2 as well and this works on both.

I am soooo stoked! I simply can't believe he was able work in such tight quarters, fit all this in there, and still have room to suggest including built in s-video and all that other stuff on his mod site! Simply unebelievable...
Zach knows his stuff and is an all around very nice guy. Thanks soooo much! I am thrilled with the work you've done!
