Let's see, pay $2 a month, goes down all the time (I've been kind of watching the discord). Need to re-install apps and do the same thing as before. If you played with this early on retail. You knew, if you wanted upgrade your versions, you needed to back up your stuff (saves, save states, and settings), Remove old version, Re-install the app, and restore your settings. Once RetroArch was upgraded again, do it all over again. Real PIA.
Honestly, I would pay $2 so I could get updates from the store and not need to deal with that BS. This is not the case.
It was nice playing Super Mario World while chatting on Xbox live, sometimes people just want to chat and I live and die by gaming (as much as an adult can these days) but, the headache with paying $2 and not being able to use it when I want to, I don't see the value. These days are gone...
If you want to know WHO did this... Nintendo, they sent a complaint that people were playing Nintendo games on their Xbox and Microsoft blocked it to save the hassle of dealing with Nintendo.
If you want to play Retro Games on your Xbox, $20 for Dev mode is a good value but, I have so many other devices that can play up to Switch games on Emulation, I think I am going to not use the Xbox any more...
As for Xbox and not playing retro games, Xbox supports games from their first console and YOU don't have to rebuy it (if you still own it), like Nintendo does and Sony does as well. Microsoft did as many games as licensing allowed.
If anything, Microsoft is cool here, they let it go for a long time before they blocked it.
