メリ爺のゲーム万歳

Play NES games on Android in 2026: which RetroArch core to pick (Mesen, Nestopia UE, FCEUmm, QuickNES), a 10-setting run-ahead config, controllers and fixes.

Gamepad not detected in Mesen 2, or Mario walking on his own? Fix controller recognition, map NES/SNES buttons by feel, tune the deadzone for stick drift, set up Turbo A/B, and try exclusive fullscreen to cut input lag.

Which SSF version to install, how to check the one you have, and how save states, fast-forward and the Screen tab really work in PreviewVer R33 on Windows.

Gamepad dead in your emulator on Windows 11? Test it in joy.cpl, rule out Steam Input, then check the connection, mode switch and driver, in that order.

Connect an Xbox, DualSense, DualShock 4 or other gamepad to Android, confirm it is detected, map it in RetroArch, PPSSPP and Dolphin, and fix common problems.

Emulator lagging on Android? Measure speed first, then separate settings load from overheating, audio sync and slow storage. RetroArch and PPSSPP explained.

PCSX2 slow, stuttering, crackling or stuck on a black screen? Find the cause with the speed overlay, fix the right setting, and roll back from Nightly safely.

Buying an Android phone or handheld for emulation up to PS2 in 2026? Why Snapdragon's Adreno GPU matters, the Pixel caveat, and what to check first.
