No need to be signed into Xbox Live (which you shouldn't do on a modded console anyway). Cons:
High. Once moved to the correct directory ( Content/0000000000000000/[TitleID]/00000002/ ), the Xbox 360 dashboard or Aurora/FSD usually recognizes it instantly. (NTSC – Jtag/RGH) (Game DLC)
Since these are original game files, they perform exactly as the official releases did, with no added lag or graphical glitches. Pros and Cons Pros: No need to be signed into Xbox Live
DLC often requires the latest Title Update (TU) to be installed, or the game will simply crash or ignore the new content. Technical Verdict (NTSC – Jtag/RGH) (Game DLC)
NTSC (North America/Japan). While Jtag/RGH consoles are region-free, matching the DLC region to your base game (Title ID) is often necessary for compatibility.
