(noob) Making repro nes carts

[Nerdy Nick]

Hi, i've allways wanted to make a couple of nes carts like earthbound etc.
now i dont really know what im doing so im here hoping to get some kind of guidance.

ive been looking into it heaps and got a basic idea of what do, ive never soldered anything before or messed around with eproms but i do have a pretty good background in computers.

Before i go into the hard stuff i was going to do a basic hack of a Smb, like this: http://beigerecords.com/cory/Things_...ouds_2005.html just to test if i can i burn and solder the eproms properly, if i can do that then il move onto bigger stuff.

now what im most worried about... THE PARTS

Ive had a look at a bunch of similar tuts and they all use differnet eproms ( some use 27C256 and some just use 27256) so im really confused which are the right to buy.

i currently put a bid on these (27256) http://cgi.ebay.com.au/ws/eBayISAPI....MEBI:IT&ih=005

If you were bothered to read everything i cant thankyou enough ( i know noobs are annoying)

not 1000% sure. But i believe this is the part you need. You can get it from the mouser catalog for $5.10 each plus shipping which will be cheaper than getting it from Australia. Unless, of course you are from Australia.

also this one would be brand new, not a pull from an old board.

And unless I am mistaken there is a typo on the ebay listing. it should be a 256k not 265k.

and if i get these chips then what sockets should i get

because theres different types for 28pin, narrow, machined etc
