<p>CHDBOY is an Android port of the CHDMAN tool that converts disc images (BIN/CUE, ISO, etc.) into compressed CHD archives. CHD (Compressed Hunks of Data) is a lossless compression format that efficiently combines multiple files into a single compressed archive, significantly reducing storage requirements while preserving perfect quality of the original media. This app provides a mobile-friendly solution for compressing your game backups, saving valuable space on your device without any loss of data.</p>
<strong>Status:</strong> Google Play submission candidate. The app is currently free. If you enjoy it, please consider supporting future releases when they arrive on the Play Store.

<h2>Highlights</h2>
<ul>
<li><strong>Smart mode detection:</strong> Automatically picks createcd or createdvd based on your source so you never guess the right command.</li>
<li><strong>PSP-aware compression:</strong> Uses the recommended hunk size for PSP ISOs to keep conversions compatible and efficient.</li>
<li><strong>Duplicate CHD protection:</strong> Existing CHDs with matching names are skipped to save time.</li>
<li><strong>Background-friendly:</strong> Accept notification permissions so conversions can finish even when the app is closed.</li>
<li><strong>Lossless space savings:</strong> CHD shrinks multi-file disc images into a single lossless archive.</li>
</ul>
<h2>Getting Started</h2>
<ol>
<li>Install the APK or build from source (see below).</li>
<li>Use the Android Storage Access Framework picker to select the folder that contains your BIN/CUE/ISO files (no legacy storage permission required).</li>
<li>Confirm the files you want to convert.</li>
<li>Wait for the notification when compression finishes. Large ISOs can take a while, so let the app run in the background or rely on notifications.</li>
</ol>
<h2>Building from Source</h2>
<pre><code>./gradlew assembleRelease</code></pre>
<p>Artifacts will appear in <code>app/build/outputs/apk/</code>.</p>
