Perfect Dark challenges help!

[Shujinco2]

Ok, I'm seriously getting peeved with Perfect dark. I have 4 challenges left to do (26, 28, 29, 30), and they just seem impossible.

In the N64 version, there was a glitch that allowed you to change the whole setup of the challenge, replacing darksims with meatsims, or changing the level, etc. HOWEVER, since I have the X-box 360 version, I cannot seem to do that.

So, basically, I need super awesome, somewhat fool-proof methods for beating challenges 26, 28, 29 and 30. Also, if you could find a version of that glitch for the 360, that would be win too.

Here are the stats:


Challenge 26:

Scenario: King of the Hill
Arena: Ruins
Opposition: TechSim 1 (Perfect)
            TechSim 2 (Hard)
Weapons: Falcon-2
         Mauler
         Cyclone
         Laptop Gun
         Reaper
         Disabled

Points needed to win: 10
Time Allowed: 10 minutes
Note: The sims are INCREDIBLY accurate with the reaper. Also, the level design is serious fail. REALLY easy to get lost.


Challenge 28:

Scenario: Capture the Case
Arena: Villa
Opposition: GuardSim1 (Dark)
            GuardSim2 (Dark)
Weapons: Falcon-2
         Falcon-2 (silencer)
         dy357 magnum
         AR-34
         Shotgun
         Disabled

Points needed to win: 10
Time Allowed: 10 minutes
Note: Just normally hard due to Darksims.


Challenge 29:

Scenario: Combat
Arena: G5 Building
Opposition: WorkSim1 (Dark)
            WorkSim2 (Dark)
Weapons: Falcon-2
         Cyclone
         dy357 magnum
         CMP-150
         Dragon
         Disabled

Points needed to win: 10
Time Allowed: 10 minutes
Note:Also incredibly hard because of Darksims.


Challenge 30:

Scenario: King of the Hill
Arena: Skedar
Opposition: BlondeSim (Dark)
            CassSim (Dark)
Ally: JoSim (Normal)
Weapons: Falcon-2
         Falcon-2 (scope)
         MagSec-4
         Mauler
         dy357 magnum
         Disabled

Points needed to win: 10
Time Allowed: 10 minutes
Note: They can fire pistols MUCH faster than you can. MUCH MUCH faster. Also, my teamate just sucks in general.
