[REQUEST] CHD file format support

Postby luke_70it » Wed Aug 08, 2018 1:57 pm

Ciao,
I'm an old psx fan, and when I discovered fpse, I purchased it and I'm very happy with it.
Since some games are very big, I was comparing some CD image compression methods to save space on my cell phone, and I found that best format is MAME CHD.

Thank you very much
Luca

I took a look and the internal compression system of fpse is far better, it use a high level of compression .

Have you tested the compression feature available from fpse?

It compress automatically games ?

Thank you for your reply.
I'm back from holidays and I can try the compression feature!

I'm not be able to compress a cue+bin game (Crash Bandicoot PAL), directly from fpse. A progress bar starts for just a second, but does nothing :-(

I also tried the pc tool Pocket ISO, but fpse doesn't find the game in .bin.bz format.

How does exactly the compression feature works?

Does fpse open the compressed game without completely uncompress it?
If I undesrtand it correctly, PBP and CHD files are accessed without uncompress the whole file.

BTW Crash Bandocoot is 600mb uncompressed, 535mb compressed with Pocket ISO, and 441mb in CHD format.

Thank you very much
Luca

The game is stored on external sd, and i'm using a Galaxy s8, with Android Oreo.
Is this a problem related to write permission on external sd?

Thank you
Luca
