I have found three different versions. The one on EmuXtras is 5.0a and the one posted here and on gamebrew is 5.1f.
But I for some reason have a v5.2 on my hdd since 2021. Don't even remember where I got that from. I tried the 5.1f version and it seems there's quite a lot of difference the startup intro for example isn't the pixel styled one but the handrawn one in 5.1f.
Is it available on XBMC4Gamers Download section? I can't check becauee I don't have a way to connect my Xbox to the internet atm.
