Nintendo campus challenge dumping

I was wondering if there was any specific reasons as to why nobody dumped the roms of those competition cart for nes and snes seeing as they are available in reproduction form at retrousb... I tought they were already but after a few search I was surprised to find out they don't seem to have been released yet. Did they add somekind of protection to them ?

 

Well, I was thinking of that but wanted to be sure not to waste my money on something that is very hard to dump or was dumped already.... I don't have much equipment to dump stuff at the moment but I was wondering what kind of memory chip retrousb is using. Maybe I could dump the chip directly in a eprom programmer or such? I always thought dumping nes cart was much harder than SNES but maybe by desoldering the rom chip it would make it easier.

 

Well once you have the cart it won't be wasted money because you will be able to play on real hardware.

If a unique cart makes a difficult dump is there a way you can access the data directly from a retail console if tweeking is what you are looking to do?

 

Well it uses dipswitches so that may be an issue needing hacking and it's possible maybe even likely that the RetroUSB version has had measures taken to prevent easy reproduction. But the existence of the RetroUSB version shows it was dumped by someone at some point.

 

maybe retrousb paid for the rom, or is paying a per-repro fee to the dumper, who knows

 

You could read out the cart's ROM with a device programmer but you probably won't be able to use it since the game's hardware won't be emulated. It's almost certain that the ROM is altered in some form (and possibly watermarked) since nobody would dump something like that without wanting credit. The original cart has a custom microcontroller for communication and dual port RAM (otherwise a straight forward design) so undoubtedly the hardware is different == even more likely the ROM is adulterated.

 

I wish some one would! I'd love that rom!!!!

 

Well the Nes version is probably out of my league as far as dumping it as I do not own a copynes and reverse engineer mapper is out of the question for me and won't be able to desolder the rom chip and dump them as they probably use SMD component. I was more interested in the Snes version as it would be probably easier to dump with a copier. I wish i could see a scanof the pcb to see what were up against! But i have a feeling they must have done something to prevent easy dumping of their investment...
