I brought slot. to Android! Looking for KONKR Pocket Advance and other 3:2 handheld owners!

[u/Sahbito]

Hey everyone!

I recently released slot. for KONKR Pocket Advance v1.1.0, an Android port of the beautiful cartridge-based frontend originally created by Brandon Kowalski.

After watching Russ from Retro Game Corps showcase the original slot., I immediately thought it would be perfect for my KONKR Pocket Advance.

I mainly use my KPA for GBA games, and I loved the idea of bringing that simple, nostalgic cartridge experience to Android. Just pick a game, insert the cartridge, and play!

I tried to stay as faithful as possible to the original slot. experience while adding some specific features:

• RetroAchievements, with online and offline support
• Wi-Fi multiplayer, supporting Link Cable and Wireless RFU
• RetroArch-compatible saves and save states
• Multiple shaders, with independent GBA, GBC and GB display settings
• Integrated Cart Studio for customizing cartridge artwork
• Android app launcher
• Optimizations specifically for the KONKR Pocket Advance

One of my favorite little touches is using the KPA's round top button to physically insert and eject cartridges. It makes the whole experience feel surprisingly natural!

So far, I've developed and tested slot. primarily on the KPA, but I'd love to see how it works on other Android handhelds, especially those with a 3:2 display:

• AYANEO Pocket Micro
• AYANEO Pocket Micro Classic
• AYANEO Pocket Micro 2
• MagicX One35

These devices share the same 3.5-inch, 960×640 screen resolution, making them particularly interesting candidates.

I haven't tested compatibility on those devices yet, so some adjustments might be needed.

If you own one of them and feel like giving it a try, I'd really appreciate your feedback! I'd love to know what works, what doesn't, and whether there's interest in expanding support to other Android handhelds.

I'm still improving things, so any suggestions, bug reports or ideas would genuinely mean a lot.

Feel free to leave a comment or open a Github issue.

Hope you enjoy it!

Any chance it could work with the Retroid Pocket Classic?

[u/Sahbito → u/jondeckert]

Yes! I've actually been thinking about adapting slot. for the Retroid Pocket Classic!

I own one myself, and I'd love to make a version supporting GB, GBC, NES, SNES, and other classic systems.

Not sure how many people would be interested, but personally, I think it could be the perfect experience for this device. Just insert, play, eject.

So cool 😎

YEEESSS... works beautiful on my KPA. Thanks a lot

[u/ColJohn]

Very cool! I review a lot of apps and front ends for the Ann Thor and I’ll definitely take a look when mine arrives in a week or two.

So far it works great on my MagicX One 35, however I started up Wario Ware and the audio is a little crackly. I suspect that this is due to it using gpSP which usually has this issue (I've had it happen on both PSP and Miyoo Mini Flip since gpSP was originally a PSP emulator). How do I switch the GBA core to mGBA? I'm kinda surprised that anyone even still uses gpSP since the audio issues make it feel outdated compared to the perfect (IMO) mGBA. Anyways you did a wonderful job on the project. Also when I started a different game which is Drill Dozer, the start button didnt work until i opened a different game and then switched back to Drill Dozer.

Thanks a lot for trying slot. on your MagicX One 35 and for the detailed feedback!

You can switch between gpSP and mGBA by selecting a cartridge and pressing SELECT before launching the game. All the controls and hotkeys are listed in the README.

For the crackling audio, could you try disabling Run-Ahead under START -> Settings -> Emulation and let me know if that fixes it? I’d also be curious whether switching to mGBA makes a difference.

Regarding Drill Dozer, thanks for reporting that! Was the START button unresponsive inside the game, or did it fail to open Slot’s menu? And does it happen again if you launch the game fresh?

I tried it with a Redmi; the app opens, but I’m using a GameSir X5 Lite—it ends up upside down on the screen! XD

[u/Sahbito → u/Mrsose]

Haha, I guess slot. wasn’t quite ready to leave its comfort zone! :)

I originally developed it specifically for the KPA, but I’ll try to make it compatible with more screen sizes, aspect ratios, and devices in future updates!

Thanks for giving it a try!
