Dominator01 posted a Q&A that fills in a lot of the details around Retroarch on Xbox.
Question 1 - who ported retroarch or ppsspp to xbox one was it you
Answer - no it wasnt me who ported retroarch to xbox one that was a user named kryzs-h a user who knew how to make things work good enough for all of us to have fun - and for ppsspp it was hrydgard the ppsspp dev who ported it to uwp
Question 2 - are you a dev for retroarch or ppsspp?
Answer - no im not a dev i dont know how to code anything but i wish i could do more to help but my skills are nonexistent
Question 3 - if your not a dev what is your involvement with retroarch/ppsspp?
Answer - i figured out how to compile retroarch and ppsspp because whenever i relied on others the builds wouldnt have been updated in years sometimes so i took the time to compile each build so others that were in my shoes who dont know how to compile could just grab the latest from me, since i was compiling builds i started making retroarch and ppsspp videos on my youtube channel and started helping others who had issues, also when compiling, errors would occur so i reached out to both autechre (the retroarch dev for pc) and hrydgard (the dev for ppsspp for pc) and they'd help fix compile issues and sometimes something breaks on retroarch when it used to do something just fine i gotta compile 30 or so builds sometimes to see when it broke and then autechre would fix the builds for me and i'd compile and share fixed builds
Question 4 - you know libretro.com has xbox one builds already what makes yours so special
Answer - those are from me, i compile for autechre (the retroarch pc dev) and he updates the site with the builds i send him
Question 5 - how come autechre doesnt work on the uwp port if he's the dev?
Answer - altho he has an xbox one it doesnt seem like he's all that interested in fixing stuff thats specific to xbox one and so builds for retroarch have been buggy and sometime straight up not working(edited)
Question 6 - was there other emulators for xbox one before retroarch/ppsspp?
Answer - yes, nesbox was first to my knowledge and it supported nes,snes,gb,gbc,gba,sega genesis, etc and then a gba emu for uwp that works for xbox one released also a chip8 emulator was ported then a scummy site came around called xb1emu that he "ported" and stole source code for emulators and sold them to people, called gifer, floating digits, and inter calender, which was separate emulators for psx n64 and gba and yes they work but there very buggy and expensive but alot of people bought them none the less, then there was retrix a emulator that was pretty much retroarch rewritten in another code language so its less of a mess emulator and is clean and simple to use, the author of that goes by absestos and that emulator was free it also supports many systems
Question 7 - was there other emulators on the retail store at some point?
Answer - yes xb1emu site started hosting hidden emulators on the store and the only way to access them was first you had to pay for it then he'd give you a code and then when you launch it it was just a calender for example until you pressed certain buttons and the emulator would appear, and then there was xbrowse a stolen retrix source code port for retail that was just a webbrowser until you entered certain (url i think) then it would be retrix but with a redone ui that looks like a emustation frontend, and the last (for now) is tnavigator (2/3 and 4) which again is a rewritten retrix without permission from absestos and he's been selling and sometimes comes back to sell but at least he put some effort into it and didnt just make a new ui he also made new cores ui settings etc that retrix didnt have
Question 8 - whats so special about your ppsspp build instead of just the regular builds?
Answer - i found out how to make my own custom homebrew store so now you wont have some homebrew and none of the ones people really wanna play, i work on this brew store once in awhile and only put up stuff i like or think is well made and not some flash game with terrible controls and is awful to play
Question 9 - is the xbox one the only builds you have for ppsspp with your custom store?
Answer - no i have both xbox one and pc versions with my custom homebrew store available at

Question 10 - why not just upload these homebrew and emulators to ms's retail store?
Answer - we'd need permission from the owners for homebrew games also some hombrew games require copyrighted code so that wont happen, also emulators are banned from the store and anything added is taken down, there used to be emulators on there store just fine b4 the original xbox one came out and then they removed all and changed there policy(edited)
