Here's a quick explanation of how I got Philips CD-i to run on Odroid XU4 with OGST image using CHD files

Here's a quick explanation of how I got Philips CD-i to run on Odroid XU4 with OGST image using CHD files. You can do the same thing to get Neo Geo CD running too but I have problems (see bottom). There's a lot of posts explaining how to do this on a ton of systems/OS's and I pieced this all together from others' methods. I can't throw each of them a bone so thanks to all of them. The emulator that seemed to work best for me so far is mess2014 but mame (no year) will work too. Mame just cuts off 1/5 at the top of the screen and prints a jacked up looking “CDI” and Mess is full screen. May be changeable?

For CD-I, CHD files must be in your roms folder, in a folder called cdimono1 with BIOS file cdimono1.zip as well (There are at least 2 diff versions of that BIOS and the one that's 468.7kb is the one I got to work). The folder name and BIOS file name match for a reason so double check.

Now to the somewhat convoluted part...you must get a cdi.xml hash file, create dummy zip files with the MAME style names used in said .xml, and change the names of your CHD's to fit what is in the .xml as well. I can hear you about to say “Screw that” but: There is an archive page with CHD files already named correctly (Hint MESS 0.149) and a page with .zips of premade dummy files and .xml hash file together (Hint cdii.blogspot) so it ain't really that bad if you download all of those files.

Otherwise...for example, the cdi.xml hash file is set up like this for each game:

<software name="jokers">
		<!--
		Origin: TOSEC
		<rom name="Joker's Wild!, The (1994)(Philips)(US)[!].iso" size="647388000" crc="633d2fec" md5="40c77801cbfba93d42d4bc00fec79a68"/>
		<rom name="Joker's Wild!, The (1994)(Philips)(US)[!].cue" size="130" crc="5082d284" md5="7581ed503c07f1121eedb41667ff2f21"/>
		-->
		<description>The Joker's Wild! (USA)</description>
		<year>1994</year>
		<publisher>Philips</publisher>
		<part name="cdrom" interface="cdi_cdrom">
			<diskarea name="cdrom">
				<disk name="joker's wild!, the (1994)(philips)(us)[!]" sha1="a5609953241b49d64bfdfd671edfdffc93b4b3dd"/>
			</diskarea>
		</part>
	</software>

The SOFTWARE NAME and DISK NAME are all that really matter here. If you found the premade dummy zip file pack referanced above, skip to the next paragraph. To create your own dummy zips, right click in your cdimono1 folder, select create document, select empty and, in this example, name it jokers.zip as noted by the software name entry above.

If you downloaded the correctly named CHD game files stated above, skip to the next paragraph (remember that all the CHDs have to be in the cdimono1 folder with no subfolders). Otherwise, change the name of your CHD game file to what it says in the DISK NAME entry. This one would be “joker's wild!, the (1994)(philips)(us)[!].chd” which is the same format as the iso and cue but it seems the use of capitol letters creates problems in the emulator.

Now that everything is named the way it has to be, create a folder called hash in your “ROMs/mess2014” folder (or “ROMS/mame” for mame). If you've never ran mess before you won't have that folder in there already so create that too obviously. Place the cdi.xml file you downloaded earlier in the new hash folder.
For instance: /home/odroid/ROMS/mess2014/hash/cdi.xml

Now you may be able to launch using RA or ES (after changing your cfg file to tell it to run CDI Roms with mess2014) but running via terminal is best to see what may be going wrong (good idea for any emulator you're struggling with). It will tell you at the end of the script if your BIOS is incorrect by stating “cd200.rom NOT FOUND (tried in cdimono1 cdimono1)”. It'll pop up errors for cdic.bin and slave.bin but that's normal as there are currently no versions availible. Thanks to Meveric's shell script, all you have to type into terminal is:

libretro-xbmc mess2014 “/home/odroid/ROMS/cdimono1/jokers.zip”

It is calling for the dummy zip file which will lead it to your CHD via the xml hash file. It seems to hang on a turquoise screen but the CDI screen will come up soon enough. Controllers will not work and your keyboard up and down arrows will probably be all that does do anything, so hit TAB which will get you into simple Mess/Mame options. Choose “Input (For this machine)” to set up controls (will have to for each game you run the first time unless you wanna screw up all arcade controller settings). I set it this way for my wired Xbox 360 controller but I'd imagine it's the same for any:

• Mouse button 1: A
• Mouse button 2: B
• Mouse X Analog: n/a
• Mouse X Analog Dec: Left
• Mouse X Analog Inc: Right
• Mouse Y Analog: n/a
• Mouse Y Analog Dec: Up
• Mouse Y Analog Inc: Down

Select “return to machine” and you're ready to rock. There are some games that just don't work so make sure you're trying to play a compatible title before you freak out. There is, aparently, a hard to emulate video chip so games like Creature Shock won't work (luckily it's on several other systems). I am sad the Monty Python titles won't work until someone smarter than me creates an actual emulator for it, though I don't see that happening. I was about to pull my hair out working on this, as I'm sure some of you have and gave up. Enjoy this strange little machine and it's odd array of games!

 I can't thank Meveric enough for the work he's done and continues to do!
