Common Errors & Fixes

Error: Could not find cue sheet data track

• Fix: Ensure the .cue file lists all .bin files correctly. Open .cue in a text editor. File paths must be relative.

Error: Cannot open file: Permission denied

• Fix: In Termux, run termux-setup-storage and restart. For other apps, use a folder under /storage/emulated/0/ (not external SD card unless app has root).

Error: chdman: not found

• Fix: The binary isn't in your PATH. Use ./chdman instead of chdman if running from same directory.

Deployment Methods for chdman on Android

Given these constraints, users and developers have engineered three primary ways to run chdman on Android:

Method 2: Using a GUI App – "CHDMan GUI for Android"

If the terminal scares you, there is a newer alternative: dedicated Android apps that wrap chdman commands into a button-tapping interface.

Recommended App: CHDtoid or ROM Converters (search Google Play or GitHub for "chdman android" – apps appear/disappear; always verify source).

Steps (General for most GUI apps):

1. Install the app.
2. Grant storage permission.
3. Select input folder (containing .cue/.bin or .iso files).
4. Select output folder (where .chd files will go).
5. Tap "Convert".
6. Wait for completion bar.

Note: Many GUI apps are simply front-ends. They still require the actual chdman binary embedded in the app. Ensure the app is updated to support Android 13/14 scoped storage.

Loading and Running ROMs

1. Load ROM: Tap the "Load ROM" button and select a CHIP-8 ROM file (.ch8 or .rom).
2. Run ROM: Tap the "Run" button to start executing the loaded ROM.

3. Converting GDI to CHD (Dreamcast)

Dreamcast uses .gdi + multiple .bin tracks. Use:

chdman createdvd -i "game.gdi" -o "game.chd"

Option B: Compile from source (MAME)

1. Install build tools:

   pkg install build-essential git python ninja
   

2. Clone MAME source:

   git clone https://github.com/mamedev/mame.git
   cd mame
   

3. Build only chdman (saves time):

   make REGENIE=1 TOOLS=1
   

   After building, copy chdman from mame/ to your PATH.

Part 2: The Old Way vs. The New Way (PC vs. Native Android)

The old workflow:

1. Transfer ROMs from Android to PC.
2. Use Windows chdman with batch scripts.
3. Transfer the compressed CHD files back to Android.
4. Delete the originals.

This worked, but it was slow, required a computer, and broke the flow of tinkering on the go.

The new workflow (chdman on Android):

• Run chdman natively using Termux (a terminal emulator) or a dedicated GUI app.
• Convert files directly on your external SD card or internal storage.
• No PC, no cables, no waiting for transfers.
