CHD stands for Compressed Hunks of Data . It is a lossless file format designed for MAME/MESS to store dumps of hard disks, CD-ROMs, laser discs, and floppy disks in a compressed, chunk-based manner.
Example: chdman -c lzma,flac = LZMA for data, FLAC for audio. | Media Type | CHD size (raw → compressed) | Example | |------------|-----------------------------|---------| | Hard disk (CHD-HD) | 50–90% | chihiro , naomi hard drives | | CD-ROM (CHD-CD) | 30–70% | PlayStation, PC Engine CD, Sega CD | | LaserDisc (CHD-LD) | ~50% | daphne (Dragon’s Lair) | | Floppy (CHD-FD) | 60–80% | Rare, mostly converted to IMD/TD0 | mame chd
chdman createhd -o base.chd -i base.raw chdman createhd -o child.chd -i base.chd # creates empty child linked to parent Then in MAME, use -hdd child.chd — writes go to child, parent stays pristine. | Format | Compression | Random access | Write support | Audio tracks | MAME support | |--------|-------------|---------------|---------------|--------------|--------------| | CHD v5 | Excellent | Yes | Diff only | Yes (FLAC) | Native | | ISO | None | Yes | No | No | Yes | | BIN/CUE | None | No (needs index) | No | Raw PCM | Yes | | GDI | None | No | No | Raw PCM | Via CHD | | NRG/MDF | Poor | Partial | No | Partial | Limited | CHD stands for Compressed Hunks of Data

I’m Tony Stark, the voice behind most mod app reviews you’ll read here. I’ve been into Android customization since childhood — it started with playing around with old rooted phones like Oppo A37, Vivo 1906 and turned into 7–8 years of hands-on experience with modded apps and games.
Over the years, I’ve tested hundreds of APKs on different Android versions (from 6.0 to 14), across devices like Oppo, Xiaomi, Realmi, Samsung, Vivo, and even emulators like BlueStacks. This helps me spot compatibility issues most people miss.
I don’t just rewrite what’s already out there — every app I write about has either been personally tested or deeply researched. That includes checking for fake mods, virus-injected APKs, and overhyped features. If something works, I’ll explain exactly why. If it’s trash, I’ll say it straight.
I’ve written for multiple APK and tech sites before, but this site is where I go deep — no fluff, no filler, just clear and honest mod info from someone who actually uses this stuff.
