Honestly I have very little interest in Emulation on Android these days. If anything it was more for my phone to be able to play decent games out and about (not that we can do that now with the current global situation). I'm more known for Amiga emulation here and have been chipping away at the missing Amiga media (videos, disks & boxart etc.) for a while now, with what little free time I have. Most of the emulation I've done lately is in PCVR with EMUVR and New Retro Arcade: Neon. My Youtube channel also takes up much of the free time I do have. So no I'm not looking to start any other projects, I wish you all the best with the Hyperspin modification.

As I said NOT ALL apps have launch intent implemented. Best thing to do is message the developer and ask for them to add the feature. I did this a looong time ago for Redream (Sega Dreamcast) and tested the APK before it was released on the Playstore. Arc Browser has no profile for Duckstation standalone, only the RetroArch core. Freelancer adds profile updates for us to use for popular emulators, of course it's possible he's not done the profile yet BUT from what you've said it sounds like launch intent isn't being used in DS.

Try "org.devmiyax.yabasanshioro2/org.uoyabause.android.Yabause", that's for the free version not Pro though. I'm not paying the developer again when the old version could have been restored on Google Play, if he wanted it to be. Remember not all apps will work with launch intent which is how frontends load them. Download QuickShortcutMaker from the Playstore to your phone and install the app you want to know the settings for and it will list the activity names.

No worries. With the recent forced changes to Retroarch breaking compatibility with Hyperspin, using Arc Browser which is actively developed makes even more sense now

My honest advice would be to purchase Arc Browser on the Google Play store and use that. It's actively developed and being constantly improved upon and sadly Hyperspin isn't. I actually have both configured on my STV. That single purchase can be shared with your family account and/or used on your Android phone, so although it costs money you can get quite a lot of use out of it. Arc Browser has ready made system presets and can scrape artwork online for the games. It integrates with the voice search which is a nice feature, you can say "Sonic" and all the Sonic games from all the systems you've added to AB's library will show. It now supports video previews, you can add favourite games (Hyperspin doesn't do that), choose to use Retroarch 32 or 64 bit versions for separate systems...I could go on and on. In short it'll make your life easier and is honestly a better frontend. Hyperspin will have to be configured manually through the ini files in the "settings_android" folder. Yes the Hyperspin themes do look more flash than Arc Browser BUT many of them use swf in the zip files, so aren't compatible on Android (trust me I know, having tested and fixed soooo many of them for my STV). It's definitely worth the time doing Hyperspin and Rocketlauncher on PC, as you can do many more systems than on Android. It's your decision of course but hopefully some advice from an experienced retro gamer (i.e me) helps.
