How do I know if my cart has been dumped?

[Az]

Real dumb question here. I'm rather out of touch with the ROM scene, so forgive my ignorance. This isn't advocating piracy or ROM begging, so please don't misunderstand me.

Far from being a big tymer, but I've got a lot of 16-bit pirates and other oddities, along with a few obscure import carts. I have both a Multi Game Hunter and a Double Pro Fighter so I've got the ability to dump (most) of the carts I own.

Granted, I don't have anything completely unreleased, but I'm pretty sure I've got a few cart variations that have not been dumped previously. I'd like to make sure that if I have something that's not already out there, I make it available for those that would care.

What is the best resource to check and see if my cart has already been dumped? In other words, can someone refer me to a site or program that would list all available ROM variations? The closest thing that I know of offhand would be to refer to one of the Goodtools lists, but they are way outdated and I don't want to duplicate work that has already been done. I've seen that the No Intro group dumps a lot of stuff, but can't seem to find an exact list of what's been done and what hasn't.

Just google the name of the rom you're trying to find info on.

Use a program to check the MD5 sum of your files against the nointro dats, nsrt (snes), and goodtools sets.

Download the No Intro (http://no-intro.org/) dats. They have a listing of the CRC32 checksums of games for most systems. If you have something that isn't in their list, it is probably best to make a post about it in their forums, and they can help you out.

You could tell us what you've got. Specifically pirates, I'd be interested to know if you've got anything not dumped since I specifically have an interest for pirates :)

Doesn't the No Intro omit pirates and pirate variations, unlike Goodtools?

[Kiddo]

No-intro has some omissions (fan-made ROM hacks and translations the obvious ones, more controversially - and perhaps with some degree of inconsistency - prototypes compiled rather than dumped), but last I saw pirate cartridges weren't amongst them. Various Unlicensed games are at least in older versions of the DATs.
