So, replacing arenas is definitely one of the simpler mods to tackle, but yeah….if you’ve never done it before it can be overwhelming.
First, you need to decide what arenas in WL you want to replace. Go to red roosters Wrestling Legends Install and support thread. Scroll past all the stuff about installation and look for the link he gives for all the arena ID’s, wrestler slots, etc. You’ll see that arenas are “bg” files (bg10, bg26, etc.) Let’s say you decide to replace bg12 (whatever arena that is - I’m not looking at the list at the moment). I’m guessing you know how to access your files on your XBOX360, so do that and find the bg folder. Find bg12 and right click it to see how many mbs it is. Let’s say it 10mbs. If the Backlash 01 arena you want to replace it with is larger in mbs (even just the slightest bit) you can’t replace bg12 with it. You have to find a bg file that’s larger than the one you’re inserting.
Ok, so now let’s say you’ve found one. Let’s say it’s bg14 and it’s 8.5mbs. Let’s say your Backlash arena is 7.5 mbs. We need to get your Backlash arena to be the exact size as bg14. So download a Hex program, like HxD. (By the way, before you go any further, always make a backup file of the one you’re going to replace before you edit anything. Just in case.) Drag bg14 into HxD and also your backlash arena. Scroll to the bottom of each file in HxD. You’ll see that the larger bg file goes much farther. On the left hand side, you’ll see numbers and letters. In your backlash file, start adding zeros (and only zeros) at the end of it until it matches bg14 EXACTLY. Not one zero more, not one zero less. Save it.
Now, you simply need to rename it to bg14, both inside HxD and the file itself. Inside HxD, scroll your backlash arena to the very top. Look at the right hand column. Start scrolling down a bit until you see whatever bg number it has been assigned by justyn1893. Let’s say it’s bg25. Simply highlight the numbers 25 and change them to 14. Hit save. Close HxD. Now, right click your backlash arena file and rename it to bg14. That’s it. All that’s left to do is to drag it back into the bg folder in the game and you’re good to go.
Now, it still won’t have the correct arena screen when you choose it in game….that’s a tutorial for another time. But you can at least use the arena in the game.
Hope that helps. I’m writing this after a very long day, but I don’t think I forgot anything.
