Developers restore “retail” Xbox emulators after Microsoft crackdown

It’s been about three months since Microsoft cracked down on a number of emulators designed for Xbox consoles and distributed via a loophole in the Xbox Store. But that crackdown hasn’t stopped the Xbox emulation community, which this weekend launched a new version of those “retail mode” emulators that they’re confident will be able to evade Microsoft’s automatic detection and removal tools.

The newly accessible emulators come courtesy of the “UWeaPons Store,” a name that references the Universal Windows Platform program that allows generic Windows apps to be distributed to Xbox consoles in the first place. Subscribing to the group’s Patreon for $2 per month puts supporters on an email “whitelist” that allows access to “Le Bombe,” a package that can install Dolphin (GameCube/Wii), XBSX2.0 (PlayStation 2), Xenia (Xbox 360), and RetroArch (multiple older consoles) on a standard Xbox console.

That new unified distribution package is partly designed as a way to avoid the algorithms that were automatically flagging and blocking previous attempts to distribute UWP emulators through the Xbox Store, according to emulator developer SirMangler. “We wrote a new package from scratch and stripped as many identifiable elements as possible, including all the emulators into one download,” he told Ars in a Discord chat.

SirMangler declined to talk in too much detail about those “identifiable elements” to ensure the package would continue to avoid detection. But he said that reorganizing and rewriting the entire “manifest” from the ground up, and grouping the emulators into a single download, should help mask some of the structural details the package reports back to Microsoft and make it “a little more interesting for Microsoft to detect.”

“Short of Microsoft enforcing manual reviews for every upload, I can’t think of any countermeasure they could employ that I couldn’t work around.”

Despite the precautions, SirMangler recognized that “eventually [Microsoft will] find out about the apps and terminate the account.” When that happens, though, he added, “hopefully that won’t last too long” before a new version is uploaded. A new system for managing the “whitelist” of supporter’s addresses has also streamlined the process for those reuploads, SirMangler said, so supporters can be re-added to the new versions’ list and the emulators can “be back and running in a few hours of us knowing [about a takedown] without too much trouble.”

“Retail is massively preferred…”

The UWeaPons Store effort to get emulators working on retail Xbox consoles is completely separate from a pre-existing method for downloading a wide variety of emulators and tools to an Xbox set to “Developer Mode.” The Xbox Emulation team says it will continue to provide updates for those open source Developer Mode versions of their emulators, which can be accessed without subscribing to the Patreon and without any need to be added to a whitelist.

But despite the continued availability of that option, which hasn’t faced any pushback from Microsoft in all this time, SirMangler says there’s still value in challenging Microsoft’s enforcement of a longstanding prohibition on emulators distributed to “Retail mode” consoles through the Xbox Store.

That’s partly because some international users don’t have the necessary payment options to front the $19 (or equivalent) necessary to sign up for an individual Xbox developer account. Beyond that, though, SirMangler told Ars that “retail [mode] is massively preferred by a lot of people. It’s convenient to have your games and apps organized in one spot… there’s also a lot of people who love to introduce their family to emulation and may prefer retail [mode] for accessibility for their children, for example.”

As of early Monday morning, nearly 600 users had signed up for the UWeaPons Store Patreon, a level of support SirMangler says he “didn’t expect to happen so quickly.” We’ll see just how long those supporters can enjoy emulation on their Xbox before Microsoft’s next move in the never-ending cat-and-mouse battle.
