downloading games to the 2600 in Atari 2600 Posted February 3, 2018 · Edited February 3, 2018 by Trip2018 There is a type of SD Card that does this, if the Harmony supports it. People have used them with the Ultimate Cart on the 8-bit computers successfully. Toshiba FlashAir SD WiFi card. Ohh yeh I forgot about the Wi-Fi SD card. It lets you send/receive, doesn't it? And I would think the only compatibility issues that'd arise would be the FileSystem and size. If the Harmony can hande it, it'd be good to go wouldn't it? You could then transmit your games to the VCS without having to worry about plugging and unplugging the SD card. Personally, I believe the tech world tends to create solutions to problems that don't exist. In fact, I might suggest a Harmony cart user have several SD cards at the ready. One with favs, one with space games, one containing the early first 2 years of releases.. Or homebrews. Or whatever. Just a thought. Alternatively, if you're one that genuinely likes to play with tech toys, then, yeh, sure.. The Wi-Fi SD card + Harmony could be a solution for you, if they work together, just that it would operate slightly different than a PlayCable or GameLine. You could potentially write a script to transfer groups of roms to the card on a set schedule, thus simulating a broadcast. That'd get you closer. Just thinking here. That's a great idea. I didn't know that wifi sd cards existed, Thanks.
