Basically. It's a minor inconvenience, especially given the consoles these carts are for need you to touch a nearby spot on the system to power off anyway. Same deal with Everdrive GBX7 vs GBX5.
X7 costs twice as much as an X5 because it has a real-time clock (only about a dozen games use it, like two of which left Japan, both of which you have no real reason to play on original hardware outside of nostalgia purposes, all of which have workarounds in-game in case your battery is dead or missing), save-states (at that point why aren't you emulating?) and an in-game menu (even less convenient than just resetting the cart). It's fluff to make it seem "more complete" but isn't worth shit. The GBX7 can't even claim it covers all games because it lacks Kirby Tilt n Tumble's gyroscope.
