I'm trying to work on a game translation, and I've been using xenia to test out changes. I figured it'd be better if I actually tested stuff on console instead, so I invested in an x360key since soldering scares me and I properly installed it. The problem is that it won't run the .iso that I've compiled with exiso, which runs fine on xenia, and it gives the error "This disc is unreadable." While it will recognize the unmodded game rip just fine, I can't run it as my console is NTSC-U/C and the game is region-locked to Japan only. Is there some certain way that I should be compiling the iso? Is it that xk3y can't run modded games (I don't think this is the case considering all the GTA mod videos online)?
