Citar:

Step 1 - Double click the convscd110.exe file

A little black window that says something along the lines of "Command Prompt" should appear.
A prompt asking for the name of the ISO to be converted should appear in this window.

Step 2 - Type the name and full path of the ISO file and hit the enter key

Example:  c:pathtomyisosmycoolgame.iso
After you've done this a little menu of sorts will appear asking you to choose a destination
region.

Step 3 - Type the number of the region you want to convert the ISO to and press enter

That's it.  ConvSCD will have created a new file for you with the converted version. The file
will be in the same directory as the original with a similar name (original name + conv + U, E,
or J depending on the destination region).
