Yes, I can't imagine ROMs in there that haven't been examined before.

I got a reply from Rob Fulop about three game titles that I had seen in a gaming catalogue back in 82.  He kindly put the mystery to rest for me so I would just like to say many thanks Rob for your help.  Here is the qoute he gave me :-

 

"Scuba" was my in-house working name for the game that would become Fathom.

 

if I'm not mistaken, which is totally possible, I believe"Zone" was a working name for the game that became Quick Step, authored by David Johnson.

 

Demon Attack II was on the marketing wish list, and I don't believe there was anybody ever assigned to work on it.

I know Quick Step was called Kwibble at one point (I think there's a proto with that name out there) but I never heard it called Zone before.  I guess it could be though, the game is weird enough that Zone fits it just as well as Quick Step.

No worries but the thanks should go to Rob who kindly answered my age old questions :)  It was good to finally put closure to the three titles I saw advertised over 30 years ago and it was cool to finally put rest to the runour of Demon Attack II.  Thanks again Rob for your generous input. ;)

Got a new dump for you guys.  Hopefully people still read this thread :)  Smurf Rescue in Gargamel's Castle Canal 3 version.  It differs only 3 bytes, one is meaningless (reset vector high address).  Didn't investigate the other two...

 

Enjoy :)

Two new pieces of info today, I picked up Spider Fighter and Qbert from CCE.  Aparently Spider Fighter has already been dumped, although it is marked as missing on the Atarimania Database.  The Dump is unique.  Qbert is the same as the 1987 Atari release.  Perhaps Atari used the CCE version?  Unfortunately nothing new, but at least the games can be marked as dumped.

New ROM today, CCE Missile Command.  It is unique, by 4 bytes.  One is the high address of the break vector.  The others I do not know.  Would be interesting to know if the Easter Egg is in this version.

 

Also some info on other CCE titles marked as not dumped... Frogger, Space Invaders, and Duck Fighting are all equivalent to their USA releases.

@Rom Hunter:
Yesterday I reorganized my rom collection for use in Stella and Harmony cart (which is basically your collection integrated with a selection of homebrews, demos, hacks and NTSCtoPAL conversions and subdivided in folders by TV format and then alphabetically). I like the long filenames (the Harmony can display them just fine) and I also keep the variations and duplicate roms with alternate names.
A couple of suggestion for the next version:

- You should add back these "Superman" and "Seaquest" roms: they were removed as bad dumps, but later I found them again in a pirate console, which confirms that they were actually released. (see this post).

- You should remove the "joined" "Party Mix" roms (both PAL and NTSC), as it is not a multiload game. Those roms won't work in emulators nor in flashcarts, you only need the split ones for this game.

@Wickeycolumbus:
The "Missile Command CCE" rom you posted differs by 4 bytes if compared with the Atari release with the Rob Fulop's initals removed, but only by 1 byte (the high address break vector) compared with the original version.

Yeah I discovered the joined Party Mix rom didn't work right at MGC last year.  I need to get the individual files.

Here is the 5th (and last ?) SECAM Activision game:
 

Attached File  River_Raid_SECAM.bin   4KB   21 downloads

 

 

river_radi_S_mainlabel.jpeg river_radi_S_endlabel.jpeg



Besides the reduced color palette, there are a few differences with the PAL version:

- CARB text on the tanks instead of FUEL
- Tanks are 8 pixels wide, while on PAL and NTSC they're 7 pixels
- No trees
- No "E" and "F" on the fuel indicator

PAL version:

river_raid_P.png

SECAM version on PAL console:

dump1_1.png

SECAM version on SECAM console:

dump1_3.png

As you can see from the screenshots, colors were chosen to look good on both PAL and SECAM consoles, which is not the case for the other 4 known Activision SECAM games (they look mostly grey on PAL hardware).


The label was starting to fall off, so I could peel it away without damaging it and have a look at the board. I also desoldered the rf shield to read the text on the IC.

Excellent work, Alex!
 

I'm glad the cart arrived safely and fully working.

This was indeed the last SECAM title that was missing.

That's weird. Seems like an unfinished job, like if the idea was to replace them (with "0" and "1", for example), but after removing the old graphics they forgot about it!

No surprise, the PAL conversions of Activision are pretty lousy too.

 

BTW: The explosion graphics have been changed too.

They should have replaced them with the letters P(lein) and V(ide). Perhaps that was not possible to fit in?

BTW: I don't think the Activision PAL conversions are lousy.

Which Activision PAL titles were badly converted in your opinion?

No problem (see below). icon_smile.gif

All I have seen so far. None of them are speed adjusted or use the extra screen space. And sometimes the colors are missing detail (e.g. the sunset effects).

Most prominently in Pitfall II. A PAL game lasts 24 instead of 20 minutes, there are large black borders at top and bottom of the screen, the jungle greens are reversed, the sunset effect is gone.

I believe that, in case of Pitfall II, the cause of most of the graphic changes is SECAM compatibility.

After they had to produce a separate port of some of their games, Activision people became a bit smarter and decided they can just have a single version for both tv formats. If you play a bit the game with SECAM colors in Stella, you see that colors are quite decent. Too much do be a coincidence IMHO.
I'm sure this is also the case for some Atari games released in the early '80s. Battlezone, Mario Bros, Pole Position, Asteroids and others looks fine in SECAM, and lacks some color shades compared to the NTSC versions (battlezone being the most evident case).

Damn SECAM!

 

:D
