I removed his pan by replacing his Mega Buster with the kick attack. His special weapon is the Crusher. I'd tell you all how to do it right now, but I'm trying to simplify it first.
Well, nevermind that... Here's how to do it:
In your saved game, you need to have at least the "Jet Skates" and "Hydro Jets" in your inventory. Make sure that whatever special weapon you want to use, you have it equipped before you enter any of these cheats. One of the downsides of this cheat is that when you have roll change your special weapon, or if you use one of the modifier codes to change your weapon, Megaman's right arm dissapears and parts of him turn pink! The coolest weapons for playing as Apron Trigger in my opinion are the Crusher, the Hyper Shell, and the Blade Arm.
I'm using the ePSXe emulator, but this should work with any emulator.
You also need PEC. If you don't know what that is, go here:
www.emucheater.com/To use PEC with ePSXe, you need to change your video plugin to the PEC plugin. Don't worry, PEC uses your original plugin for video.
Now that you've got PEC installed, open it up and press F3 to open the User Database. Now, click add cheat and under Title, name it something like "MML2 - Change Model". Underneath the "Codes" box there are two small boxes. In the bigger one, type: 3008C252. In the smaller one, type: 0003. Now click Add.
This is the code that lets you change your player model by equipping different shoes.
For the next code, repeat these steps, with these changes: Under Title, name is something like "MML2 - Change Texture". The code for this cheat is 3008C252 00FF. Enter it in like before, then click Add. This code does the same thing as the previous one, except it changes the texture of your player instead of the model.
Now, activate ONLY the "change model" cheat by putting a check next to it. Click OK in the bottom right corner, then hit F9 (this sends your codes to the emulator). DO NOT CLOSE PEC PROBABLY!
Now open ePSXe (or your emulator) and load your game. If you open your inventory and close it, you'll notice that megaman's model changed, depending on what shoes you had equipped. Now, to change him into "Apron Trigger", equip the Hydro Jets. When you unpause, you'll see that he's changed, but his texture is all screwed up!
To fix the texture, pause your emulator and go back to PEC. Hit F3 to go to the User Database again, and simply remove the check from "change model". Now put a check next to "change texture" and click the bottom right OK again. Hit F9, resume your emulator, and open your inventory. Change your equipped shoes to the Jet Skates, and Voila! you are now Apron Trigger.
Unfortunately, when you change shoes, it will still change the texture. There's a code to work around that, but the problem is that his texture automatically changes back to normal when you enter a new area sometimes, and you want to be able to change it back easily. I'm working on fixing that though, so be patient.
By the way, you can play as other characters too. Do the same as above. But use these shoes:
Model Code:
Tron - Jet Skates
Apron Trigger - Hydro Jets
Matilda - Asbestos Shoes
Glyde - Cleated Shoes
Gatz - Hover Shoes
Roll - Nothing
Texture Code:
Tron - Nothing
Apron Trigger - Jet Skates
Matilda - Hydro Jets
Glyde - Asbestos Shoes
Gatz - Cleated Shoes
Roll -

(someone put roll's texture code up recently, check the forum)

- Hover Shoes ( I think this is sera or something, but I've yet to figure out her model code. I'll find it though.)
If you have any questions, just ask!
P.S. To get rid of the frying pan, use this code: 3008C23E 0001. This replaces the Mega Buster with the kick attack.
