Can The Atari Flashback Play Cartridges

Most Atari Flashback consoles cannot play cartridges because they were built with preloaded games instead of a cartridge slot. The Flashback 2 is the main exception people talk about, but only after an unofficial mod, and compatibility is still hit-or-miss. If you want original Atari carts, the Atari 2600+ or 7800+ is the cleaner official route.
