figuring out what dependencies are required by a rom

[sticcino]

Hi.

Setting up a folder with just games we want to see and have the master folder of the other games and addition files in it..

For example 19xx works in the folder that it came in, but when I copy the rom to my clean folder it doesn't come up.

Using openEMU on mac to test the roms. Checked online and the sites don't list a parent for this particular game, there are other games that do the same thing.

Is there any way to tell if a rom requires another rom or bios to be located in its folder?

Thanks,
JH

@sticcino compatibility lists show which parent is needed if it's a clone. Also any mame database will tell you the same. And it is all irrelevant which is which if you choose the wrong romset in the first place.

@sticcino I am picking up a couple things from your message. First, most of us keep the roms zipped. There are no folders used, just a single folder filled with zip files, and the actual ROM chip files are zipped up inside them. That said, I think MAME can work with them unzipped in folders of the same names, but maybe not FBA.

Second, MAME is able to look at multiple zips to load dependencies. In other words, the necessary files can be in other zip files (or other folders, if your ROMs are not zipped), but as you say, 19xx has no parent ROM.

Assuming you are using the correct romset for the emulator you are launching, it sounds like you might have a permissions problem, either with the folder, or the files themselves. Where exactly is this "clean" folder you are using, and what emulator are you using?
