I'm fairly new here and I don't know if this has been asked before I would like to know If there are any resources I can read up on to program a cart I know there's different things like hi low res carts, how would I go about finding that out? I would mainly like to change languages on an original cart from jap to English as I can't afford some of the us releases e.g earthbound...
You can't reprogram a cart, but you can hack it to change it's chips. There are actually several options for what you want to do, what your describing being the most destructive and difficult. Many are listed here, http://wiki.superfamicom.org/snes/show/Testing+Code#real_hardware_6 , but a quick overview of flash carts that would likely suit you best would be: Mash-Mods Flash Cart SNES PowerPak Tototek Flash Cart Neo Flash Myth Cart Super Everdrive R.A.M. Factory 64SX
I Know it's a little destructive but yeah man I want to make a repro cart I know there's different chips involved and that they have to match up... I found snes dev site which is good.. I will be getting a large bunch of carts so I thought why not...
