Hello

Probably a question with an obvious answer, so please bear with me, I really tried to find an answer on my own...

Anyway: I'd like to convert a CD ROM image (PC DOS 2000 cd in .ISO format, no CUE) into a .chd, because apparently I need a .chd with MESS.

Chdman gives hints of its own, so I try:
Code:
chdman createcd --input PCDOS2000.ISO --output PCDOS2000.CHD


I get this on the console:
Code:
Input tracks: 0
Input length: 00:00:00
Compression:  cdlz (CD LZMA), cdzl (CD Deflate), cdfl (CD FLAC)
Logical size: 0
Compressing, -1.$% complete... (ratio=100.0%)

Here it seems to hang, although the CPU remains busy.

Can anyone help me?

Thanks! Martin

P.S. I am using SVN head as of today.

chdman does not support ISO. You must feed it bin/cue or bin/toc right now.

Thanks! I used ISOBuster to convert the ISO to cue/iso, and then renamed iso to bin.
Now the conversion worked fine.

Yeah. I'll be adding direct iso support to chdman soonish now that the v5 bugs have settled down (u8 fixed the problem with LD-CHDs), but in the meantime ISOBuster's quite handy for that smile

Oh, does that mean we can start converting our v4 CHDs now? smile

Which CHDs?
Are you speaking of the MAME ones?

MAME or MESS; also the chd convert-and-remain-uncompressed function on the MESS wiki may need to be updated if nobody has done so yet.

For MAME, convert only the ones that aren't BAD_DUMP in u8 (ie, most of the CD and GD-ROMs). The rest I left the old hashes since they're going to be bad either way, and this way you don't have to waste time converting them.

Hey RB, iirc Haze mentioned looking into adding ECM to chdman, do you know if he has abandoned that idea or if it's still in the works? Great hearing about the upcoming ISO support!

there is basic ECM compression in there, it automatically gets used if ECM data is present and matches what would be generated. Only real places you're going to notice it is in the Saturn / PSX sets where it's common tho (helped shave another 50 or so gig off the Saturn set) I'm not sure it's quite as aggressive as other similar solutions out there because I haven't looked at them, but it works.
