I wonder if this is because of BIOS licensing. I haven't used Drastic in a while, but I do know that "perfect" DS emulation requires a couple files that are only available by dumping from your own machine... Nintendo has been on a copright troll-roll with the recent GilvaSunner takedowns, I almost wonder if this is part of that initiative.

In any case, this is another one for the "why sideloading is important" wall, it shouldn't be too big of a deal since the Drastic developers can continue distribution with or without Google's blessing. No Bleem! politics here, just a little bit of downtime so the devs can set up their own payment portal and dump the credentials of their paid customers for continued support. Heck, I wouldn't be surprised if they just open sourced the thing and threw it to the community. DS emulators are a dime a dozen these days, and the devs have probably already made their money here. Any way it breaks, it should be a win-win situation though.
