I may soon be interested in borrowing a Bung Xchanger for reverse engineering. (Or if you want to donate, if you feel particularly inclined.) I can not offer monetary compensation at this point, but if you're actually using the Xchanger and need a replacement I can lend you a USB flasher. (Similar to the Bleepbloop flasher.)
i only have a bung xpander ^_^. what do you need it for? maybe ask in #nesdev irc on efnet, someone there might have one.
if i had one i could, i only have a bb programmer =P
Nitro I have one Bung Xchanger like this one: , send me an email to [email protected] to negotiate ;-)
