18 Game & Watch classics come to the ZX Spectrum through a free SM510 emulator

A 1982 computer running Nintendo LCD games: that is the bet from SANYALnet Labs, whose developer Supratim Sanyal says no generative AI was used. According to Time Extension, his Sharp SM510 processor emulator, written in Z80 assembly, lets you play 18 Game & Watch titles on a ZX Spectrum 48K, real or emulated.

These are not graphical remakes: the emulator runs the original code and reproduces the clock, the LCD segments and the score, with support for wide-screen and dual-screen games. The lineup includes Donkey Kong, Donkey Kong II, Donkey Kong Jr., Mario Bros., Mario's Cement Factory, Mickey & Donald, Oil Panic, Snoopy Tennis, Manhole, Turtle Bridge and seven more. A demo and "Munchy", an original Pac-Man-style game, are included.

What you need to supply

The project is free on the SANYALnet Labs itch.io page (version 1.0.0, personal non-commercial use), but Nintendo ROMs are not included. For the 18 classics you need the 4 KB SM510 ROMs from your own collection, which a bundled Python script converts into a TZX tape. Munchy and the demo run without any ROM. The detailed procedure (loading with LOAD "", choosing Game A or B) is on the same page, which doubles as the getting-started guide. You need a Spectrum 48K or an emulator that handles TZX tapes.
