To be able to create an arm patch, you're going to need a couple of things:

1. Program that supports Photoshop Plug-Ins (.8bi). Programs that can use Photoshop plug-ins include Adobe Photoshop and Paint Shop Pro (download free trial version here).
   
   
2. Red Storm's RSB Plug-In from the Rogue Spear CD.

Now to install the plug-in, follow the directions provided with the program your using for installing plug-ins.

• For Photoshop, you would have to copy the plug-in file (RSBBitmap.8bi) into the /plug-ins folder in the Photoshop main directory.
  
  
• For Paint Shop Pro you must first create a plug-in folder within the Paint Shop Pro file (which is usually located under Program Files) and then install the RSBBitmap.8bi plug-in.

Here comes the fun part. The first thing in creating any image is, well, creating the image. How you do this is totally up to you. We recommend that you create your image on a big canvas. This means that you should create your new image with a size of 80x80 pixels or something close to that (be sure to keep the width and the height at the SAME value). This will give you a good space to work with. Also be sure to have your image created using the RGB color palette (or convert it to RGB if you have to), this will allow you to save it as RSB's and other image formats. After creating your image, resize it to 32x32 pixels and save your image. When you go to save it BE SURE TO SAVE IT AS A RSB. Now all you have to do is follow the same steps as the installation process.
