Pokemon game + DualScreenDex
Automatically detect the Pokémon currently on your screen and display their stats, weaknesses, and resistances instantly.
Description
DualScreenDex is a companion Pokedex app designed specifically for dual-screen Android gaming handhelds (like the Ayn Thor). It uses live OCR screen scanning to automatically detect the Pokémon currently on your screen and display their stats, weaknesses, and resistances instantly.
Forks
DualDex
DualDex is a passive Pokédex companion for mainline-family Pokémon games running in RetroArch. Keep the game on the AYN Thor's upper display and DualDex on the lower display, or use its optional resizable overlay on a single screen.
Unlike the original OCR-based approach, DualDex parses the user's own GB, GBC, or GBA ROM into a local Pokédex and combines it with checksum-valid SaveRAM and supported read-only live-memory layouts. It does not use OCR, screenshots, cheats, memory writes, bundled Pokémon data, or per-ROM-hack profiles. Unsupported capabilities fail independently, so a ROM can retain its static Pokédex even when a live-memory feature is unavailable.
Advantages over the original:
- ROM-derived species, forms, types, moves, descriptions, sprites, encounters, and type mechanics
- Seen, caught, team, Area, rarity, and battle context where the selected ROM exposes validated structures
- Live Gen III party detection where the ROM exposes a structurally validated party layout, without waiting for an in-game save
- Organic discovery mode that conceals information until it has been observed or captured
- An Area roster that puts known Pokémon first and masks unseen local encounters without revealing their identities
- Docked lower-screen mode and an optional floating 4:3 overlay
- Automatic RetroArch content detection with manual ROM selection as a fallback
Setup guide
- Download the signed latest prerelease.
- Install the production APK and open RetroArch Setup in DualDex.
- Grant Android's All files access when prompted. DualDex uses it to discover sibling ROM folders, RetroArch SaveRAM, and the public RetroArch configuration.
- Let the setup page enable RetroArch Network Commands and the recommended SaveRAM autosave setting, then restart RetroArch if DualDex reports that the configuration changed.
- Start a supported Pokémon ROM in RetroArch. DualDex should activate the matching local catalog automatically; manual ROM selection remains available when automatic activation cannot resolve it.
- Leave Display mode on Docked for the Thor's lower screen, or explicitly enable Overlay and grant Display over other apps for the floating companion.
Compatibility and limitations
The latest prerelease keeps the stable companion layout and adds structurally resolved live Gen III party reading, so a newly received starter can appear in Team before the player performs an in-game save. The Area filter retains the newer Organic-mode encounter visibility: known local Pokémon are listed first, while unseen parsed encounters appear as disabled silhouettes with masked names. Experimental world maps and THUMB ability-mechanics decoding are not included in this APK.
The parser has been exercised against a documented ROM-hack corpus, but support is capability-based rather than an all-or-nothing compatibility claim. See the current ROM Hacks Compatibility report and Parser Compatibility report before testing a particular hack.
The protected workflow signs production APKs. The package, version, download hash, signer, and installation on a Thor are verified before the registry entry is finalized; hands-on gameplay validation remains part of prerelease testing.
