Is it possible to use Sega CD merged bin?

[POPEYE]

Can I convert CD Image to merged bin / cue?

[mitu]

Yes, you can convert to .chd using chdman. .chd file are supported by the lr-genesis-plus-gx emulator, you can install it and use it as default for Sega CD.

I have tested cue / bin created with Alcohol 120% works fine.

You may want to give the CHD format a try @POPEYE. You'll save at least 60% of space vs bin/cue with no impact on performance

[POPEYE]

The problem that I can't find the program for Linux that could make right cue to multi-track single bin.

[gomisensei]

you can't convert a cue/bin with multiple bin files to one bin file, those are most likely audio tracks. You can, as mitu suggested, convert them to a single .chd file with compression for the audio and save yourself space and number of files.

No it is possible to do so. The problem is, that there is no Linux software that could create correct cue for that bin (only Windows software), so I can only create toc / bin in Linux.

@POPEYE You asked about merged bin/cue file. chd is a format which combines one .cue and the .bin files - referenced by that .cue - into a single .chd file. What exactly are you trying to do - explain in more detail your problem ?

Just trying to merge without using Windows software.

Then use chdman.exe, as I said before, and it will produce a .chd file from your .cue/.bin files. Said program is part of MAME (mamedev.org), so you can grab it from there. Here's a link on how to use it.

As far as I understand, this action is reversible and I can get images back as they were?

Create CHD:

chdman createcd --input "file.cue" --output "file.chd"

Extract CHD:

chdman extractcd --input "file.chd" --output "file.cue"

[gomisensei]

@POPEYE more like

chdman extractcd -i file.chd -o file.cue -ob file.bin

but i'm not sure how it works with multi-bin's, i have none to test

I can confirm it works with my multi-track .gdi's...

I've tried and it seems to be working. It even can pack toc / bin, and unpack to cue / bin. But, I still don't know what will happen, if I will use different versions of chdman. I only figured out, that v5 starts from MAME 0.146.

By the way, what version of chdman in RetroPie Manuals ( https://drive.google.com/file/d/0B-ElaPpvBHs5aUd0QUM3c05kY2c/view ), and what is it's system requirements?

I have already got one time trapped with toc / bin which is impossible to use outside of Linux and almost impossible to convert to other formats (you can try to convert to nrg using old nerolinux or to cue / bin using chdman).

It's v5. The older version are deprecated and lossy.

[POPEYE]

@mitu But from what version of MAME is it (must be written in help of the program)? Is it 32 or 64 bit? I've tried it in XP, it says: "not a valid win32 application".

[mitu]

@POPEYE It's a 64 application.

[POPEYE]

Can somebody tell, from which version of MAME (0 . xxx) it was taken?

[mitu]

Given that v5 is the last version of the CHD format, I think anything included in MAME 0.146 and later should be compatible. I don't think the latest version supports Windows XP (even the 32 bit one), so if you're looking for a compatible version try an older release.

[POPEYE]

It is from MAME 0.205 (x64) release.
