Odd filetype
 

I recently obtained what I believe is an iso of Mobile Suit Gundam Renpou vs Zeon, but it is actually fifteen different files.
they all have some strange numbers as an file extention, such as:
o-msgun1.001 all to o-msgun1.008 and o-msgun2.001 to o-msgun2.008. Does anyone know how to properly process these files into an iso?

use WinRAR.

How? I open one file with winrar, and it has a 692mb .cdi file in it, but so do all of the others.

let me break it down for you. backups for DC usually come in .cdi images. which can reach the filesize of 690MB, or bigger/smaller depending on the size of the image for a game. anyway, in order to upload it without uploading the whole image and risking corruption, release groups use WinRAR to split the files in 19MB files. older versions of winrar used the .001, .002 , etc. extension, while the newer versions of winrar use the, rar, .r00, .r01, .r03, etc extentions. but the newer winrars still support the older extensions.

so now, your game has the, .001, .002, .003, etc. extensions which means you open any of the files in WINRAR. a .cdi image should appear. click on the image once. click the extract button to extract the image from the files. it will automatically combine the files and put the image on your hard drive. burn the .cdi with dj or a120.

hope you can get it to work.

I got it to work. I did not know that about winrar.
Thanks.
