Dreamcast GDI to Mame CHD Converter

[Linky]
This is a quick AutoIt script that will have CHDMan batch convert GDI game disc images to the Mame CHD format.
Why do this? Well simple...a huge space savings over uncompressed GDI's. The resulting CHD files can be used with Demul for DC emulation.
Anyways here is an example using "Crazy Taxi v1.004 (1999)(Sega)(NTSC)(US)[!][6S 51035]"
zip = 105mb
chd = 118mb
gdi = 1.10gb
So while not as small as a GDI thats zip compressed...it's certainly smaller than the uncompressed GDI.
You will of course have to use the gdrCHD plugin.
FYI the GDI's can be in archives (7z, rar, zip) or uncompressed in sub folders of the Parent folder, since the app does support recursion of sub folders.
C:\Parent Folder\Game 1\Game 1.gdi
C:\Parent Folder\Game 2\Game 2.gdi
C:\Parent Folder\...\...
Note:
At present I have no way of reversing the conversion from CHD to GDI, so PLEASE do not delete your compressed GDI's.
Scratch that...I do now: [Linky]

Hey DJ hows it going?
Nah there shouldn't be anything needed other than the two files in the archive.
Now you are trying to convert GDI's correct and not CDI's...as I know you where chatting with Frequency or someone else about CDI's.
This should work fine with GDI's provided by ether Tosec or Redump...course your own matching GDI dumps will work as well.
Anyways if you can get me some more details maybe we can solve the problem you are having.

Not that I'm aware of...I seen it marked as playable somewhere...but no clue how they got there...as it seems part of the system isn't emulated yet.

*Update 1*
CHDMan to 139u3 & added BIN\CUE detection for other systems than Dreamcast.
*Update 2*
Added support for the following archive formats 7z, rar, zip. This means you no longer have to decompress your GDI or BIN\CUE files before being able to convert them over to CHD.

when I try to covert a gdi to chd, from a zip file it gives the folloing error. line 2708 (file "e:\gdi_to_chd\gdi to chd.exe"): error: subcript used with non-Array variable.
I am putting e:\Silver v1.001 (2000)(Infogrames)(NTSC)(US)[!].zip on the first box then putting e:\silver on the second one. The contents of the zip are Silver v1.001 (2000)(Infogrames)(NTSC)(US)[!].gdi ,track01.bin ,track02.raw ,and track03.bin
what am I doing wrong?

Not sure why you got the error unless for some reason the script didn't find any files to begin with...but that is just a wild guess.
To be honest the Demul authors haven't stated to me or anyone that DC emulation was good when using CHD's...from my brief testing it seemed to work just fine...so hence why I put this out there as an option.
I'm sure this situation will improve as using CHD's over GDI is a major improvement just because of the vast space savings.
I honestly hope more work and research will go into using CHD's for Optical Disc Images over other formats. Meaning Plugin's for other Emu's to use the format and improvements in the format it's self.
If anything I'd love to see VitualCD applications adding support for mounting CHD's.
Anyways if a given game doesn't work yet through the gdrCHD plugin chances are the next release will have things working right.
