Item description:

Many of the achievements will
pop right away. You have been warned.

Before you do any Rehash/Resigning, make sure
to start the game first. Simply get past the screen
sizing and let it save. This will create a System
Data file. This is all you need. Use this to
Rehash/Resign the provided "NA0" file.

start the game and load up the save. It will bring
you to Mother base. This immediately unlocks:

the first few. Now return to Mother Base and
go to Metal Gear, and select Main Parts and
Walk Unit. This unlocks:

Now back out to the Mother Base again and this

the mission. Immediately you should unlock:

Stealth camouflage - 30G

In the mission, use the Stealth camo and aim
your musket at the guy in front of you. Aim
for his bunghole. If you miss, no big deal. You
have the rest of the guys to keep trying with.
Once you hit him, he should [spoiler].
You unlock:

Divine Wind - 20G

Now equip the Love Box. This unlocks:

I feel... safe - 10G

Shooting the butthole can prove to be
challenging, but I managed to with a dummy
profile with the MK 22 and Bandana
as I did this walkthrough, so it can be
done. In the options menu, I had to turn off
Aim Assist to be able to do it, so try that.
Once you do, it unlocks:

You're Pretty Good - 20G

Now climb up the ladder in the middle of the
first part of the mission and jump over to the
(I guess it's a barn) and climb to the top edge.
You should see a weird action. Do it
to [spoiler] and unlock:

Leap of Faith - 10G

Now start rolling around. Yes, I'm serious. You
need to roll around 100 times to unlock:

There's nothing else you can do? - 10G

Now either finish the mission or pause and cancel
it. Doesn't matter. Go to Mother Base and select
Delivery. Select -Free- under Address and select
any item. Deliver it to unlock:

won. If not, dispatch another team. If they win,

last mission under Main Ops, ZEKE Battle. Go to

it, Press Y at each little light to capture it. This
unlocks:

Mech Catcher - 10G

This should leave you with 43 of 50 Achievements
for a total of 750G. To get the Hideo achievement,
either get a friend to trade him for yours (also
unlocks another achievement for trading) or
simply start a new game. You can get him fairly
early. I don't know why it doesn't unlock from the
get-go. This is where my save file as of May 13th, 2013.

Alot of hours was put into this save file. You can see
by the Stats. All I ask is if you post this save file, give
credit where credit is due.
