I just stumbled upon this thread, and I completely agree with the original topic starter regarding the 2600 Centipede title screen. I felt the same way the first time I saw it as well 30+ years ago. You can give me all the factual and technical explanations you want, and at the time, limited by 1982 technology and cost efficiency, I will absolutely accept it. But as for present day and/or future technology, I see absolutely no reason why it could not eventually be done.
If you can plug it into the Atari VCS cartridge slot and play it, it's an Atari 2600 game. Doesn't matter if it has 20 gigabytes of RAM and a magical half unicorn fairy living inside of the cartridge.
The above statement is not only 100% factual & accurate, but it also perfectly describes & encompasses the ongoing controversy among video game collectors surrounding what does & does not constitute a true complete collection for any given game console. In the case of Atari carts, the use of bank switching, (larger roms), extra ram, special chips, (like sara & DPC), etc. may be viewed as "cheating" by some old school purist programmers, but if it plugs & plays on a stock 1977 console, and was available for purchase during the systems supported lifespan, then it counts as an official cart. Period! Granted, I understand the spirit of what their saying, the 4K pac-man homebrew effort impresses more then say a 32k bank switched extra ram version of pacman might.
As for the supercharger, while I agree that the supercharger's 12 games do not count as official atari carts, and never will, I see no reason (especially given today's modern technology where memory is no longer a limitation) why all the games couldn't be implemented into independent stand alone carts like the Rabbit Transit game was. (and save your breath if you plan to attack that statement because at worst, one could purchase 12 Harmony cartridges, and slap 12 homemade labels on them & there you have it)
I think the most recent example that comes to mind for me was the SNES Road Avenger (Road Blaster FX) game that was programmed & implemented onto a snes cartridge. Granted, it's a whopping 6,320 Mbit, and the largest SNES carts were 48Mbit. Granted, it may be spendy at $200 to buy a snes SD cart and a memory card for just that one game, but it is a stand alone cartridge, and it does plug into a stock snes and plays!
So is using today's available extra (virtually unlimited) memory to make games larger or better for older systems "cheating"? Yes, if you were trying to count the game as an official part of the released collection, because we are well passed the supported lifespan of the system. But it is not cheating if your merely making a homebrew game.
So while I agree that plugging in a specially modified Atari 2600 cartridge with wires & cables coming out of it, which then hook up and connect to and interface with an external independently powered laser disc player in order to allow someone to play Dragon's Lair on the Atari 2600 is cheating and does not count as an actual Atari "cartridge" game per say, if however, when the technology allows you to micro miniaturize all of that to fit inside a cartridge shell, then YES, it counts, and it's not cheating!
