DS Prerelease carts?

[Marnic]

Yo!

I just want to ask if anyone has heard about prerelease cartridges of various DS games?

The content doesn't necessarily have to be in a prototype state, in fact, I'd actually prefer it if it was the full game in some cases.
As long as the cartridge or something sets it apart from the original retail release.

I have a Pokémon Silver cartridge was used for demostrational purposes over in Australia, legit I might add, and its cartridge was a bit longer and instead of being silver its transparent. The game plays like the original games that were sold in stores.

Those type of differences!

I've been looking around, but maybe I haven't been looking hard enough!

Has anyone heard anything about something like this before?
I'd appriciate it if anyone could tell me more about it, thanks!
Any info on games like these for other systems are welcome too, preferably on the Wii or GC!

Once again, thanks a lot!

I have a handful of DS long cartridge prerelease prototype carts if you are interested. What are you offering?

Has anyone tried to dump these rare versions of retail games like that Silver copy Marnic has to dive through it to look for unused things?
