In search of a auto-region hack
Posted: Wed Sep 15, 2010 8:21 am
ok, so i saw an interesting hack that would let you swap the data bus with a single switch so that you could easily play games from another region. http://www.multimods.com/SlotMod1.html
here's the thing, i want an auto-region hack so i can be super cool. my idea was that i could probe the hucard memory to determine what region it really is for. the only thing i can think of that would tell me is a specific point in memory where it's always the same data or same pattern. i've looked at a few ROMs and it kinda looks like there is a header or sorts for most games but i'm not sure.
i had an interesting idea, reading beyond the 8Mb boundary. i was curious to know, what data will it return? garbage? mirrored data? jpegs of kittens? nothing at all? if it always returns something like 0xF0 or 0xFE, that would be perfect! anyone know?
do tell if you know of any static data (ranges), patterns, headers or anything else that would be helpful!
