Stop buying the same shite twice.
RetroShite is an offline Android app for cataloguing physical games, movies and other media. Scan a barcode to check whether an item is already in your collection, or add it manually.
See Technical Specifications for supported barcode types, scanner behaviour, and backup/import details.

- Remove multiple unused systems from Settings; systems containing items are protected
- Removed default systems stay removed after restarting
- Item title, condition, system and barcode fields
- Local SQLite storage, without accounts or a cloud service
- ZIP export with live progress and a completion message
- Merge ZIP backups from another device, adding missing titles and categories without overwriting the local collection
- Optional full replacement restore for moving to a new device
Both APKs are built from the same source, selected by the RetroShiteEdition build property. No separate source branch is required.
| Edition | Minimum Android | Package ID | Backup export |
|---|---|---|---|
| Standard (default) | Android 11 (API 30) | com.blueprint.retroshite |
Downloads/RetroShite using MediaStore |
| Legacy | Android 8 (API 26) | com.blueprint.retroshite.legacy |
Android system Save As picker (Storage Access Framework) |
The separate package IDs allow both editions to coexist on a supported device. A Legacy installation will not overwrite a Standard installation. Both editions read and write compatible ZIP backups. Hardware architecture must match the APK runtime identifier (e.g. android-arm64 or android-arm).
Open src/RetroShite/RetroShite.csproj in Visual Studio 2022 with the .NET MAUI Android workload installed, or use the .NET 8 SDK with the Android workload.
From src/RetroShite, select the desired edition at build time:
dotnet restore
dotnet publish RetroShite.csproj -f net8.0-android -c Release -r android-arm64 -p:AndroidPackageFormat=apk -p:RetroShiteEdition=Standard
dotnet publish RetroShite.csproj -f net8.0-android -c Release -r android-arm -p:AndroidPackageFormat=apk -p:RetroShiteEdition=LegacyThe android-arm example targets older 32-bit tablets; use android-arm64 instead if the tablet is 64-bit. Publish one edition at a time, or use separate output/intermediate directories to avoid mixing build products. For distribution, sign using your own signing configuration and retain the same signing identity for updates. Name the resulting signed files RetroShite_v0.1.5-signed.apk and RetroShite_Legacy_v0.1.5-signed.apk respectively.
Collection records and custom categories are stored in an app-private SQLite database; cover images are saved locally. Use Settings → Backup / Restore to export a ZIP (Standard: Downloads/RetroShite; Legacy: a location chosen in the Save As picker), merge an existing ZIP into the current collection, or replace the collection entirely. Merging skips matching barcodes; for items without barcodes it compares system, title and condition. Different barcodes are kept as separate editions, even when the title is the same. Older backups remain compatible. Settings → Optimise cover images reduces the size of photographs already stored on the device; back up before optimising.
