Games Citra MMJ could help run
These notes cover the same system but don't say they used Citra MMJ, so results may differ.
Mario Kart 7Regular Duo reviews and an earlier Duo Lite test give different results, so check the hardware, emulator and driver on each short clip below.Pocket Duo and Duo Lite
Monster Hunter 4GOne reviewer found the game stuttered at 4× after reusing another game’s profile, then improved at 3×. The emulator and driver are not named.Pocket Duo
Super Mario 3D LandReviewers report smooth play around 3×, and a written review saw drops to around 45 fps on the stock driver. 4× worked in the areas shown but could stutter in one video.Pocket Duo
Mario & Luigi: Superstar Saga + Bowser’s MinionsOn a Duo Lite running the GammaOS Nano 1.5 beta, the game hard-locked after leaving fast-forward. The reviewer says the issue is still being worked on.Pocket Duo Lite
Senran Kagura 2: Deep CrimsonOn a Duo Lite running the GammaOS Nano 1.5 beta, 2× shows some flickering. Controls then appear stuck after a Circle Pad Pro option is changed, and the reviewer is unsure whether the emulator crashed.Pocket Duo Lite
Shin Megami Tensei IVOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer reports good speed at 2× with fast-forward headroom, though much of the short stretch shown is opening dialogue rather than combat.Pocket Duo Lite
Nano Assault EXOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer reports 60 fps at the default 2×, with a brief rendering disturbance that clears. Only early gameplay was shown.Pocket Duo Lite
Pokémon Ultra SunThe regular Duo test reports a hardware-shader tradeoff at 3×: leaving it off avoids outlined Pokémon but limits fast-forward. An earlier Duo Lite test on a GammaOS beta used 2× for more headroom.Pocket Duo and Duo Lite

Kid Icarus: UprisingOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer calls it playable but reports slowdown later in the sequence. A stand helps with the original touch controls; no control mod is installed.Pocket Duo Lite
Fire Emblem Fates: BirthrightOn a Duo Lite running the GammaOS Nano 1.5 beta at 2×, repeated black flickering is distracting enough that the reviewer questions the experience, and fast-forward headroom does not fix it.Pocket Duo Lite
Project X ZoneOn a Duo Lite running the GammaOS Nano 1.5 beta, the one short battle shown runs well, without the flickering seen in the earlier Fire Emblem test.Pocket Duo Lite
Ace Combat: Assault Horizon LegacyOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer reports slowdowns in the flight footage and suggests trying 1×, which is not tested.Pocket Duo Lite
Tom Clancy’s Ghost Recon: Shadow WarsOn a Duo Lite running the GammaOS Nano 1.5 beta, the footage shows persistent rendering corruption even though the reviewer says speed looks fine, and they question whether it is playable.Pocket Duo Lite
Castlevania: Lords of Shadow – Mirror of FateOn a Duo Lite running the GammaOS Nano 1.5 beta at a confirmed 1×, the reviewer describes the opening as only partly playable and still demanding.Pocket Duo Lite
Donkey Kong Country Returns 3DA regular Duo test reports near-full-speed play at 3× after enabling hardware shaders. An earlier Duo Lite test on a GammaOS beta reports acceptable gameplay at 2×, with slower menus or scenes. Both cover a short stretch of play.Pocket Duo and Duo Lite
Mario & Sonic at the London 2012 Olympic GamesOn a Duo Lite running the GammaOS Nano 1.5 beta at 2×, the reviewer plays brief running and judo events. No frame rate or overall verdict is given.Pocket Duo Lite
Tetris UltimateOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer plays a short session and praises the D-pad for repeated inputs. No frame rate or latency figures are given.Pocket Duo Lite
Story of Seasons: Trio of TownsOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer reports good speed but sees the lower-screen interface disappear around fast-forward changes, then return. The cause is unclear.Pocket Duo Lite
Fire Emblem Echoes: Shadows of ValentiaOn a Duo Lite running the GammaOS Nano 1.5 beta, a very brief test shows flickering similar to the earlier Fire Emblem test. It is too short to judge the whole game.Pocket Duo Lite
Dead or Alive: DimensionsOn a Duo Lite running the GammaOS Nano 1.5 beta, the reviewer plays several short fights and reports a good result. The resolution is not stated.Pocket Duo Lite
Resident Evil: The Mercenaries 3DResident Evil: The Mercenaries 3D remains a poor experience in this Lite test from before GammaOS. The reviewer first misnames the driver and corrects it, tries an unnamed Turnip build, then selects the system driver; the final test still struggles. The Azahar variant, build and resolution are unknown.Pocket Duo Lite
Resident Evil: Revelations (3DS)Resident Evil: Revelations hard-crashes during this earlier Lite 3DS stream. The reviewer also says its fps counter is not working, so no reliable frame rate is available.Pocket Duo Lite
Rhythm Thief & the Emperor’s TreasureRhythm Thief & the Emperor’s Treasure runs at a reported roughly 25 fps on Lite with the system GPU driver. The reviewer cannot play the rhythm section reliably because timing is off; no working setup is shown.Pocket Duo Lite
Super Smash Bros. for Nintendo 3DSAn earlier Duo Lite test reports unstable performance, with only occasional bursts of 60 fps. A later regular Duo video shows a short 3× Azahar clip without a frame rate. Emulator and driver builds are unknown in both.Pocket Duo and Duo Lite
Pokémon XPokémon X gets a positive verdict in a short test on Lite’s GammaOS preview, with shader-compilation stutter and occasional graphical issues reported. The Azahar Nano menu shows 2× with dynamic resolution On, so it was not a fixed 2× throughout.Pocket Duo Lite
Fire Emblem AwakeningFire Emblem Awakening’s opening and tutorial battle get a positive verdict on Lite’s GammaOS preview, with some dips. The reviewer had already run the game once to compile shaders, so a first launch may run worse.Pocket Duo Lite
Luigi’s Mansion: Dark MoonLuigi’s Mansion: Dark Moon remains a poor result in the Lite GammaOS preview. The reviewer lowers resolution to Native (1×) and disables dynamic resolution, then reports little improvement, and it is still not playable.Pocket Duo Lite
Metroid: Samus ReturnsAt 4× in Azahar, one Duo review held around 30 to 31 fps on the stock Qualcomm driver and 27 to 28 fps with Mr. Purple’s T30, so the stock driver did slightly better here.Pocket Duo
The Legend of Zelda: Ocarina of Time 3DOne Duo review found it looks and performs well at 4× in Azahar and named it a standout game to try on the Duo.Pocket Duo
