Just a reminder to get any items or non-backwards-compatible games and redeem any codes from the 360 marketplace before it closes in July.
SERVICE UPDATE: XBOX 360 STORE CHANGES
As shared in August 2023, starting July 29, 2024, the Microsoft Store on Xbox 360 and on marketplace.*xbox.*com will no longer be supporting purchases. This includes games, trials, add-ons, avatar items, apps, gamerpics, game trailers, and videos. It also includes purchases like gamertag changes on Xbox 360, Game Pass Core subscriptions, in-game purchases, and Microsoft Movies & TV. Games and content purchased before that date will still play as intended and content redownloads will continue to be supported for owned content.
If you intend to redeem any codes for Xbox 360 content via your Xbox 360 console, then you will need to redeem them to your account before July 29, 2024. After that date, they may no longer be redeemable. Gift cards and subscription cards will not be impacted.
Next is a list of all non backwards compatible DLC. This does include DLC that is delisted, but if it's a game that's still available for purchase, there's a pretty good chance you can get the DLC for it too. -> https://1drv.ms/x/s!Ah_Y7CqVH4YGhPYD...a8j3Q?e=UYjhPG
all of this data is directly coming from TA, and there is no DLC filtering between listed and delisted, but hopefully, it'll still be helpful to you
