Those who could barely afford to buy the more expensive NES in the 1980s usually get their gaming excitement from Sinclair ZX Spectrum, a more affordable home computer. NES then was only a dream for many so they had to find an alternative.
Sinclair ZX Spectrum is cheaper and its 48K-memory should not be looked down upon. Despite these unglamorous features, there were many big titles associated with it, including Head over Heels, 3D Deathcase, Jet Set Willy, and Manic Miner are among others.
Marvin, the Android emulator for this home console, is a good investment. It has the exact same keyboard used for the Kempston original though it is in portrait layout.
For your comfort, you can turn the game into landscape mode so you can use a joystick, though hardcore gamers do not use this when they can still have the keyboard controls.
Everything plays out smoothly, but the Internet connection to access the “World of Spectrum” is surely more enjoyable. It is an online ZX back catalogue where you can see many memorabilia of the 8-bit history game.
According to the developer, Marvin is ideally used on multi-touch Android phone though some modifications may still be necessary if you are hoping for a fun time with games.
