Retro Emulator Reviewer and Mobile Gaming Tester

Mateusz Krol

Mateusz tests emulators the way he played the originals: one game at a time, on real hardware, until it breaks or charms him. He keeps a working shelf of old Java phones beside his Android test rack, loads the same JAR library into every build, and writes up exactly what each game does, from the first splash screen to the final boss.

Reviewing emulators since 2018 · 60+ emulator and retro apps tested

Mateusz Krol reviews emulators the way he played the originals: patiently, on real hardware, one game at a time. J2ME Loader is his favourite kind of assignment, an app with no interest in selling him anything, and he has been testing its builds against a JAR library assembled over years of collecting.

What he does here

Mateusz installs every build we publish on the full test rack, loads the same demanding library each time, and plays the way players do: on the train, on the sofa, and on a shelf of original Java handsets when a game needs a reality check. His guides come from those hours, including the keyboard layouts and profile settings that make specific genres feel right.

His reviewing standard

An emulator earns its verdict in the twentieth game, not the first: when the obscure puzzler, the temperamental racer and the 3D shooter have all had their say. Anything that only impresses with one famous title gets written up as exactly that.
