Hi. I joined this forum to help get me an answer to
an nes cart idea thats been rolling around in my head for awhile. (unless its been done)
Yeah, its roomier then it looks
To start with, i know little about 6502 assembly (and programming in general),
but was considering makeing this my learner project.
My basic idea was a rom (eventually made into the necessary cart EPROMs) that could
store passwords (like the 5+ i use online) in battery-backed ram. Nothing more
complicated then, say, 16 alpha-numeric characters (upper/lowercase, possibly some special chars)
A further development would be to use the 6502 to sudo-randomly generate said passwords. I'm
not exactally sure how random it would be, as I'm fairly sure the NES's 6502 lacks anything as sophisticated as a modern cpu's random number generator. However, to add randomness to said generation, one could solicit input from the user (couple of sprites dancing on the screen and button presses, or even use the zapper)
Even further developments beyond that would be a master password with x number of attempts
before the battery backed ram (I believe its SRAM) is wiped. For even MORE sneakyness, possibly
hide it somehow inside an existing game.
I kinda like this idea because i never write down passwords and believe in never staying signed in.
Also at 36 my memory is already developing bad sectors
Again, I'm not sure how much of this is even possible. I did a few quick searchs of this forum and google but found nothing. However i should mention that my forum search-fu and google-fu are horrible...
Anyhow, thanks in advance!
