As some of you may know, my brother Matt (BeaglePuss) and I attempt to dump and release a new proto NES ROM from our collection once a month over on NA.  We don't always get it out the first of the month, but we're pretty consistent.

Anyway, here is a link to our releases so far:

So far the list includes:

Caesar's Palace (known differences)
Hatris
SCAT (courtesy of Mason Sushi)
Krazy Kreatures
Castelian (known differences)

The ROMs can always be found in the first post, I'll bump this up with every new release we do.  Some ROMs may be very different from the final versions, some may be bit for bit the same.  Take a peak and find out for yourselves.

Hope you guys like the games!
