Any info on the other two?

 

Haunted House and Yars' Revenge protos are not in V7 collection. A simple file compare with the NTSC releases shows differences in almost all the addresses, which means that there are changes that cause a lot of code-shifting between the 2 versions.

A disassembly is needed to know exactly what has been changed.

Ok, this is something I wanted to know for a very long time now.

 

Attached ROMs are [a]lternate versions of officially released ROMs, but it's not clear to me what exactly is the difference with the original version (marked with a ~ in my collection).

 

If someone could find this out for me, I would be a happy person.

 

These are the last alternates I'm uncertain of.

Came across an interesting rom called Spy Vs Spy. It is on a 4 in 1 compilation by Bit Corp. It is a hack of Chopper Command and I have added it if anyone is interested ;)

 

Spy vs. Spy (PAL) p1!.a26

 

 

I have also added a rom called Kwibble which is suppossed to be a prototype of Quickstep (according to website I got it off) and the rom for Cosmic Avenger, again found on a 4 in 1 Bitcorp compilation which is just Star Master by Activision.

Has anyone ever checked the rom data of Hole Hunter? I am curious to know if there is any Activision programing in it purely because the sunset in the background reminds me of the Activison sunset and couple of people I know think it may have been a long lost Activison prototype. Any one any ideas? ;)

I'm guessing whoever wrote it simple 'borrowed' some Activision graphics. I doubt it was an official Activision product.

Funny.

 

I don't think Mole Hunter has anything to do with Activision.

 

Motocross however, always reminded me a bit too much of Enduro.

 

Silly thoughts ofcourse, but I always found Motocross too polished for a Taiwanese product:

I've had similar thoughts about Motocross, the score/meter/flags at the bottom also look very Activision like.

 

It would be cool to see what David Crane has to say about it. I really think it could be his unreleased "motorcycle game" mentioned in the rumor mill section of AtariProtos.

 

The information on Digitpress seems to completely contradict this hypothesis though:
