I can upload the correct image, but I wanted to notify the moderators of the reason for the edit before submitting the image.
35614 should be updated to reflect the bootleg copy. It's common for incorrect information to be submitted to text-based data fields, so we should prioritize the entry art in this instance. If the artwork for 278877 is the same as 35614, then I can merge those entries together. A new entry for the official 1983 cartridge can be submitted.
I submitted
https://vgcollect.com/item/278877 because I can neither confirm or deny that the artwork provided in
https://vgcollect.com/item/35614 is from the 2010 rerelease by the programmer. The artwork I submitted for 278877 is taken directly from the programmers (Robert Esken, Jr. aka gamecrawler on AtariAge) rerelease announcement found here:
https://forums.atariage.com/topic/155634-gamma-attack-re-released-by-gammation-on-ebay/As can be seen, both 35614 and 278877 seem to have the same label, but the cartridge designs aredifferent. The official 2010 rerelease cartridge has finger ridges whereas 35614 is a standard atari cartridge case. The sticking point is that it is well known that homebrewers recycle cartridges, but I can't confirm if all of the 2010 rerelease cartridges were sold with finger ridges or if they were a mish mash of different cartridge cases. Essentially the only way to know if 35614 and 278877 are the same would be to examine the back of the cartridges and see if they are signed and numbered.
For these reasons I tend to lean towards simply updating 35614 as a bootleg and I can submit a new entry for the 1983 original release with the correct artwork.
Update: Of course as soon as I hit the submit button, I find another post. The following post seems to confirm that the image in 35614 is indeed a bootleg:
