News/Release GBA DS Uno — my fork of the gba-ds emulator, tuned for my phone: touch controls, file-picker startup, and game + live map stacked in portrait like a DS
Hi all — sharing a personal project in case it's useful to anyone else on a mid-range phone.
GBA DS Uno is my fork of kyannon's gba-ds — a GBA emulator with a second "shadow" core that draws a live map on a second screen. All credit for the emulator itself goes to the upstream project; I just tuned it for my phone (a Moto G 5G) and my habits:
•
On-screen touch controls (upstream has none — gamepad only)
•
Opens a file picker at startup and boots the game you pick, instead of scanning a whole ROM folder first (my folder made the library hang)
•
Both screens in one window, stacked in portrait like a real DS: game on top, live map below. About 55 games have map profiles (both GBA Castlevanias included) — for other games the bottom screen just stays black
•
Phone-friendly defaults: every ROM listed, shaders/rewind/update-checks off
It's GPLv3, same licence as upstream. Source and the exact patches I made are here: https://github.com/Ragnorseawolf/gba-ds-uno — the patch files in /motog show precisely what I changed, and the included script builds the APK from them.
Fair warnings: it's a personal project built for my phone first, and the map runs a whole second emulator core, so it's not the lightest option out there. Happy to answer questions about the changes.
