Yeah, Commodore groups sit and solder together cartridges and distribute them, atari and NES games are produced.......
its not really rocket science, especially if you programmed a game.
Its just a bunch of bitchwork, really.
burn roms, shove in carts, put cart in shell, etc. etc.
Personally, I'd much rather be able to say I'm the one that sat and assembled the carts and sent them out. If I'm going to sit and do all that work programming a game I don't want some putz throwing his copyright crap on my title screen and making an arrogant mess of things.
