Dolphin – By Activision for the Atari 2600/VCS
PAL Hack. ( REAL PAL 50fps/50Hz)

UPDATE v1.1
Seaweeds on the ocean floor is now Orange like the NTSC version.

 

====================================================================================

Seeing there wasn’t an official release of the PAL version of Activision’s Dolphin. I managed to hack the the Pigs ‘n’ Wolf Atari 2600 ROM that has this game in it. Using Hack-O-Matic III. I splitted the file to 4KB that only has the game “Dolphin”.

After hours of testing. I was able to utilise it to run Dolphin only using Stella & the 2600+ with success.

How is this possible?

Using Hack-0-Matic 3 I reduce the ROM size to 4KB from the original 8KB from the H.E.S. 2 in 1 Pak. After that was done. I went to add the Activision logo by checking the address lines from the NTSC version in the correct address lines and programmed it into this PAL ROM Hack, as well as the coding to add “Copyright 1983” when scrolling to the Activision logo.

At the first attempt. the Activision logo didn’t show but the sprite that says “Copyright 1983” did.

So i dig deeper into the ROM using Hack-O-Matic. III change a few values on a few addresses that displays the Activision logo. After setting that and saving it. I tested it out one more time.

And BAM. This ROM hack shows the Activision logo on this ROM hack making it the best proper PAL Version of Dolphin for the Atari 2600 out there.

FYI: No, this is NOT A PAL60 hack. I did this on a real PAL version ROM. So you can run this on a true Atari 2600 PAL version console with the right colours.

Tested it on Stella which works, and Tested it on the 2600+ with excellent results, Works flawlessly and perfect on a real Atari 2600 4-Switcher Vadar PAL console using the Harmony Cartridge.

Enjoy the proper PAL 50Hz Atari 2600 version of Dolphin for the Atari 2600

ENJOY.
