Who owns a NTSC Z-Tack?


Rom Hunter

Recommended Posts

Okay, and now my "theory" of where the supposed rom for the NTSC version came from. This is part of a message I sent Rom a while back slightly edited:

 

 

I started looking for reviews by people that have played NTSC Z-Tack. I found this on DP:

 

http://www.digitpress.com/reviews/ztack.htm

Then I noticed at the bottom "Don't fret over not owning Z-Tack (I can't find it either, my copy is on the TV Boy system)". I didn't know what this TV Boy was so I searched and learned about it. I found this:

 

http://en.wikipedia.org/wiki/TV_Boy

Good old wiki. All the Bomb games are on there I noticed. But wait I found your two lists here and they are way different:

It got me thinking. Is there a PAL and NTSC version of this thing? I mean Joe played Z-Tack on his but I don't see it on your lists. So I searched more:

eh? Who's his friend?

RangerG says his is NTSC, and the list is supplied by Joe. All the Bomb games are there, and I think this is where the wiki info came from. Notice too alot of them say previously PAL only beside them). Then I found da Bomb.

Wow. I think this thing was dumped and that is where we got all (most) of the Bomb games from. It also explains why my Great Escape was different. These guys who made the TV Boy were taking the PAL versions and converting them so of course the real NTSC Bomb carts will be different, or in the case of Z-Tack maybe the Cosmic Town rom was used (only 2 bytes difference).

 

 

Anyhow I sent Kevin Horton an email from his website but never heard back. I'm not sure how else to get a hold of him.

 

Cosmic Town and the supposed NTSC rom of Z-Tack are very close. Only two bytes different. Surely they are related whether it be through the TV Boy or not.

I have tried all of my bomb carts on different Tv sets and diff Atari systems over the years. I was at a show with them on display and someone said they were pal so I took them around to 3 or 4 diff setups at the show and everytime I turned them on all worked perfect and did not roll and looked the same and then they guy was offering crazy money to buy them. Plus I have had them tested on a few of my setups and all worked. I guess the good thing is that they still work. Only one has the sticker "n" sticker on the back of the cart and my others have the glue spot where it fell off. I am happy with them for my collection and they should be here for a long time so I am satisfied they are NTSC. At some point they will die and just look nice sitting there then who will care then! As for a dump of the rom I dont have any where to do that.

So NTSC Wall-Defender and Z-Tack still need to be dumped.

 

Before they are all dead.

You know what? If someone has Assault and Great Escape I say do them all at the same time. That way we can compare all the Bomb carts at once.

 

@ Tom I'm sure you'll find someone close will help you. If you don't I can always help you but it'd be better to get someone in the States I think.

 

@ Rom amazing detective work. I can't believe this all started on instinct. I'm glad you want to see Wall Defender dumped too.

The person in question has showed me screenshots of both versions and scans from his NTSC Z-Tack and has AFAIK no reason to mislead me.

 

No, but it's possible he's been misled.

 

If Bomb carts used EPROMs sometimes - as apparently they did - then anyone with few scruples and a basic knowledge would know that he could sell his $10 for $100 if he burns the EPROM with a different image.

 

I'm not saying it terribly likely, but this is why you should never base knowledge on a sample of one. :)

 

A second opinion from Rick or Marco should re-enforce the theory, though....

 

It would be interesting to see if any of the NTSC Z-Tack owners from that old post have the version with the bogus ROM. AtariAger, you might want to verify which version you have before sending it to be dumped.

I believe the difference in the NTSC roms is the shape of the spaceship (and the skull/crossbone vs ball). From the graphics in this thread, I think this is what is being called the correct graphics for the NTSC rom:

and this is the incorrect graphics (possibly a hack of Cosmic Town):
