2600 Rom Comparisions and Dumps

Recommended Posts

OK, as I promised, here are the ROMS.  This dump comes from an 8 in 1 multicart which has no writing or label on it whatsoever.  But I do believe that it was manufactured either in Argentina or Brazil.  Games are accessed by turning on/off power.  Nothing too interesting on the cartridge, just 8 games that were poorly converted from NTSC to PAL.  The game list:

 

1) Star Voyager - New ROM, differs from NTSC version by 3 bytes, all timer register values

2) Mission 3000 AD - New ROM, differs from NTSC version by 3 bytes, all timer register values

3) Submarine Commander - New ROM, differs from NTSC version by 2 bytes, all timer register values

4) Dodge Em - Same as Atari PAL ROM

5) Snail Against Squirrel - New ROM, some bytes different from Bit Corp PAL, including logo removal

6) Dragonfire - New ROM, differs from NTSC version by 2 bytes, all timer register values

7) Plannet Patrol - New ROM, differs from NTSC version, including logo change to Digivision

8 ) Football - New ROM, 2K ROM doubled up to 4K, 2 bytes different from NTSC version, all timer register values

 

I have included all ROMS separated and combined for completeness.

Here is another unlabeled multicart from Argentina or Brazil, this time a 4 in 1.  All ROMs are new, but nothing very interesting, just PAL conversions.  Again, game is changed by turning console off/on again.

 


1) Infiltrate - only 2 bytes different from NTSC version, timer values

2) Nexar - only 2 bytes different from NTSC version, timer values

3) M.A.S.H. - only 2 bytes different from NTSC version, timer values

4) Keystone Kapers - Seems to have used PAL version as base, logo removed

 

Does anyone have any guess to which company made these games?  Any found with label?

This 8 in 1 multicart of 2K games has the branding Age.  The cart shell is very similar to the white cart, but has a different texture, and says Industria Argentina on the back.

 

1) Stampede - same as PAL release

2) Skiing - same as PAL release

3) Tennis - same as PAL release

4) Laser Blast - same as PAL release

5) Freeway - new ROM, has many differences including logo removal and change to road graphics

6) Combat - same as PAL release

7) Boxing - new ROM, NTSC -> PAL conversion, differs only by 2 bytes

8) Basketball - same as PAL release

Thanks for all the ROM dumps!

 

Can you please share your process for dumping multicarts that don’t have switches for selecting games (e.g. carts that require console power cycling to cycle through the games)? I have a small stack of them that I’d love to try to dump with my Atarimax Maxflash Programmer, but... I don’t know if it’s possible.

I was able to dump my multi carts with no switches by quickly unplugging/plugging back in my atarimax from the computer between each game/dump.

LOL

I've decided not to add all these Brazilian multi-cart dumps to my collection.

At the moment I have almost 1000 brazilian VCS titles still to add to our database, which is already counting around 5500 different Brazilian & Argentinian carts.

There's no end when I start adding these ROMs.

But to be consistent, you would have to remove all existing Brazilian titles, no? ?

 

Yes, this is a problem.

Where to draw the line?

Some Brazilian ROMs are interesting (they have their logo included or changed some graphics), most of them are not interesting (a few bytes difference or the original logo removed).

What to do?

The same what you would do with NTSC or PAL carts. 

 

Or maybe split the Brazilian carts into a separate collection.

Yes, perhaps.

I really have to think this over.

Brazilian ROM dumps (especially the ones without logo or just a few bytes difference) are not very high on my priority list, to put it mildly.

These, on the other hand, are:
 

- Coco Nuts (Telesys) (PAL)

- Plate Mania (Home Vision) (PAL)
- Stargunner (Telesys) (PAL)
- Stronghold (CommaVid) (PAL)
- Topy (Home Vision) (PAL)
- X’Mission (Home Vision) (PAL)

Hello,

 

Sure, even if some are not too interesting, I think they should be preserved. 

 

I used my arduino based dumper, and as AtariUCLA said, you can switch the game by unplugging/plugging back in the USB quickly.

Here is another one, this time a 4 in 1 with 8K games.  The games are changed from F8 bankswitching to UA.  Because of this the banks are swapped, so I didn't look to far into all of the differences.  But here are the obvious ones:

 


1) Galaxian - new ROM, UA banking, NTSC-> PAL, Edu Juegos logo

2) Zaxxon - new ROM, UA banking, NTSC -> PAL

3) Vanguard - new ROM, UA banking, NTSC -> PAL

4) Time Pilot - new ROM, UA banking, NTSC-> PAL, Edu Juegos/Martinsoft logo

How do you know that they are swapped? Maybe the bankswitching works in reverse?

I am not quite sure what you mean. There is a 32K EPROM in the cart, the upper 2 address lines are controlled by a counter circuit which increments every power cycle. The next highest address line is controlled by a latch that changes state with a hotspot address access.

 

Hotspot 0 makes the state 0, and makes the bank notmally accessed by 1FF9 visible.

 

Hotspot 1 makes the state 1, and makes the bank normally accessed by 1FF8 visible.

 

I realized this after looking at the dump for Galaxian, didn't check the other ROMS, I guess its possible that those are not swapped in the same way.

Here's my dump of the T-handled River Raid from Tron. Like the Robby version of River Raid, it features fuel tanks graphically changed to read COMB (i.e. short for combustível; i.e. fuel), and has "C" ("cheio"; i.e. full) and "R" (not sure but possibly "reabastecer", i.e. refuel) markings on the fuel gauge. Unlike the Robby cart, the copyright on this one was blanked out.

Hi.  This is a dump of a Ms. Pac-Man cartridge by Artkaris.  It is actually has two games which are toggled by a switch.  The other game is Phoenix.

I the only difference between the original ROM is the copyright text but I thought I would share them anyway.

Attempting to plug the gaps for the last two needed HES "single game" cartridges, I did 8K dumps of each:

 

Pigs 'N' Wolf (features Dolphin in the other half of the ROM)

Pigs 'N' Wolf (AKA Oink) (HES) (PAL).bin

 

Star Warrior (features Frogger in the other half of the ROM)

Star Warrior (AKA Star Wars - The Empire Strikes Back) (HES) (PAL).bin

 

DSC_1362.thumb.jpg.d35c123b2d66ec0a1ab6d85d5049da70.jpg

 

Attempting 4K dumps of each cart multiple times, I was able to get working standalone 4K dumps of Pigs 'N' Wolf, Dolphin, and Star Warrior. The Frogger dumps don't work properly. I can post these 4K dumps if requested, but IMO they're all just partial dumps in the end... and having them in this thread would potentially just muddy up the water, so to speak.

 

Let me know if anything more is needed with these.

Best to leave these as the original 8K with the second game included, just like Boom Bang, Challenge, Gorf and Wall Defender.

Thanks for dumping these!

I'll add them asap.

The dumps are fine, but it seems that HES added some code which prevents Frogger from running alone.

 

BTW: Any idea why HES was selling these obvious multi carts as single carts?

No idea.

Must have been cheaper for them to sell them as a single cart, I suppose.

They even mention it in their manual:
