Does "exclusive" mean "faster"? We tested three heavy hitters on a Raspberry Pi 4 (RetroPie) and an Android phone (DuckStation).
True exclusivity now lies not in the file format, but in the metadata —cover art, cheat files, and memory card integrations bundled with the CHD.
CHD does break savestates. Emulators load the CHD into a virtual CD-ROM interface; savestates capture RAM and registers, not the disc image format. chd psx roms exclusive
But recently, a new phrase has been circulating in private trackers and emulation forums: What makes these dumps "exclusive"? Are they truly different from standard CHD files, or is this just clever marketing from private collectors?
The average PSX game in BIN/CUE format takes up about 500–700MB. That adds up fast. Final Fantasy VII alone weighs in at nearly 1.7GB in raw format. Does "exclusive" mean "faster"
If you’ve spent any time in the retro emulation scene recently, you’ve likely noticed a shift in how PlayStation 1 (PSX) libraries are being curated. The days of messy .bin and .cue files taking up massive amounts of hard drive space are fading. In their place, the format has become the gold standard for enthusiasts seeking the ultimate "exclusive" feel for their digital collections.
The PlayStation 1 used CD-ROMs, which could hold up to 700MB. However, many games didn't actually fill the disc; the remaining space was filled with "dummy data" or silence. CHD does break savestates
For decades, the standard for PlayStation 1 emulation was the (or .iso) format. It was simple: one file for the data, one file to tell the emulator where the audio tracks begin. However, this format has a fatal flaw: bloat . A multi-disc game like Final Fantasy VII or Metal Gear Solid would sit on your hard drive as a messy cluster of 2GB+ files, riddled with "dummy data" used by developers to push game data to the outer edge of the physical CD-ROM for faster reading.
"I was lucky to trial PhysisTM early on when working with one of its developers. Right from the start, I've found it simple to use, quick and surprisingly accurate when I compare it with my usual calculation, having read bone age x-rays for 20+ years."
PhysisTM is a convenient and reliable method to rapidly assess a patient’s bone age at the point of care. I used to flick back and forth through the Gruelich and Pyle atlas until I found an image that matched the patients X-ray, but now I can get an answer I know is accurate within a few seconds.
