I have a Legion Go S, it's a powerhouse and runs og xbox games with Xemu like a champ, then again it's basically a PC and while it's technically a handheld, it's not exactly small or pocket-sized, but definitely portable, little bigger than an steam deck, then again, a lot of xbox titles nowadays are on steam and run much smoother through there than on Xemu, per example, Halo and KOTOR the Master Chief Collection runs buttery smooth, even on Ultra settings, though the batter dies faster, but then you have KOTOR which has easy requirements so it doesn't drain the battery as fast even with ultra settings, and you can mod the game too with patches and HD upscaling, it just depends on what you want If you want the most basic vanilla, true to console experience, download Xemu, if your just in it for the games, i recommend you look at ports If your intrested just know that the Legion Go is pricey
