While going through my gaming collection I stumbled upon a wierd cart I have. Could anyone tell me what it is? Review copy or something else? http://retroquest.se/spelsida.asp?fId=7929 More images: I haven't tried it yet, since my SMD is packed away, but I can try and get it up and running if it's necessary to identify it.
It is definitely a prototype, though there doesn't seem to be anything on the cart or the PCB itself indicating degree of completion. I'm not sure when the European version of Hyperstone Heist came out relative to the JP/US releases (I'm seeing both '92 and '93 for European), but if it was fairly close to those release dates there might be some differences in this sample from the final product. I wouldn't count on anything major, but it would be a good idea to dump it and compare the prototype and retail ROM files to quickly determine whether or not the prototype is final.
