Title: ROMS and CHDS????
Post by: 06attaker on February 20, 2008, 10:59:03 am: I've been using Mgalaxy as my frontend and have had no problems downloading the ROMS into the ROM folders. The games come up easily with Mgalaxy. But now with CHD's where do they go??? I tryed putting them in the ROM folder and they do not come up when Mgalaxy is booted up.

Thanks for any info!!!

C:\Mame\Roms\area51\

this will contain area51.chd

and all other rom files

Only true if you unzip the roms. (Hmm, unless that is an Mgalaxy bug. MXb0x3r?)

Just leave them zipped; it's faster, less disk space, and easier to manage. For your example:

C;\Mame\Roms\area51.zip <--- roms
C:\Mame\Roms\area51\area51.chd <--- chd

Where the bold text should match if you want different games.

(Dang, I was too lazy to write that the first time, but still had too.)

No, CHD's are the hard drives of some of the newer machines (year 2000 and up?) and are required for their roms to work.

NO..... CHD's are compressed hard drive images, from games that had a hard drive containing things like the game program and graphics and sounds etc etc.

Not all games had a hard drive in them. Many had all of their program solely contained in the ROM's

However, if you are trying to run a game that had a hard drive in the original arcade machine then you must have the ROM's and The CHD.

The downside to all of this is that, not many of the CHD games run well or at least not at full speed inside of MAME and many of them don't run at all.

Not really. You just need to take a quick look online and see what games are CHD games.

Not all CHD games are 2000+ and not all 2000+ games are CHD. Also, not all 2000+ games don't work because they are CHD games, but might simply not work yet. It's just not that cut and dry.
