Netplay absolutely does not work locally under any circumstance. After connecting, it's just two different devices staring at player one. No multiplayer, sadly. I've successfully set up a server and a client and got the connection to happen... But all that happens is player two is watching player one play the game... The emulator does not recognize two separate players at the same time.

Wait, if player two does get to see player one's game, then the connection DOES happen. Your controls become player two, so unless there is something for player two to do in the game, you end up watching it. I think you might be missing the requirement that a game must actually support two players (as in, two separate gamepads).

Total Garbage, STAY AWAY. Gameplay is mostly fine, but sound accuracy and quality is distorted and inaccurate no matter which settings you change. If you try using low latency sound, it is terribly choppy. Just use something like Retroarch, which is free and flawless by comparison. This was tested on an array of devices ranging up to even the snapdragon 845, 888, and 8 Gen 2. I bought this quite awhile ago, but tested it again after much time passing to find it was just as terrible. Shameful.

Have you heard about scoped storage on android 11 ? Well, my Samsung s21 ultra has android 11, and your app's explorer sees folders but no roms in the folders. This is a HUGE BUG for a paid app. Fix this please. Edit 1 after dev's answer : I have an Samsung Galaxy s21 ultra 5g. I am not doing anaything wrong. As mentioned initially : the explorer bit of your app sees folders, but doesn't see ANY game rom files in the folder. That's a classic bug in the transition to with target SdkVersion=30.

The app has been specifically refactored for scoped storage. It sees both folders and ROMs on Samsung Note10 running Android 11. In the email, I have provided you with instructions on what to click in File Selector to get proper access to your internal storage. You are welcome.

What’s new

-- Fixed file selector running underneath system UI.
-- Fixed changelist dialog running underneath system UI.
-- Fixed other activities to avoid system UI.
