FujiNet Go 800

Android Atari 8-bit emulation with FujiNet integration.

This repository contains:

• an Android UI and app shell
• native Android glue for the emulator/runtime integration
• build scripts that fetch, patch, and stage pinned upstream source trees for atari800 and fujinet-firmware

The shipped app is built from a mix of original project code plus modified upstream GPL-covered components. See COMPLIANCE.md and THIRD_PARTY_NOTICES.md.

Build Requirements

You need a normal Android native build environment:

• JDK 11
• Android SDK
• Android NDK installed under the SDK
• bash
• git
• python3
• patch
• wget or curl

The FujiNet runtime build also pulls and builds Mbed TLS during setup.

Android SDK Setup

The build scripts resolve the Android SDK from either:

• ANDROID_SDK_ROOT, or
• local.properties with sdk.dir=...

Build

The Gradle build wires the source/runtime preparation steps into the app build, but the underlying scripts are:

• bash tools/atari800/build-atari800-source.sh
• bash tools/fujinet/build-fujinet.sh --all-abis

Typical debug build:

./gradlew assembleDebug

Typical release build:

./gradlew assembleRelease

If you sign release builds locally, create a keystore.properties file outside version control. The app build reads that file if present, but it is optional for normal source builds.
