oldPick a platform and play the classics straight in your browser — or download them.
Game emulators are programs that imitate obsolete hardware — the CPU, the graphics chip and the sound hardware of a machine nobody manufactures any more. Without one, a retro game written for MS-DOS in 1993 simply will not start on a current computer. On oldgame.cz you never have to install or configure one: the emulator is compiled to WebAssembly and runs inside the page, so a game loads about as fast as a video clip.
20 platforms, 37,331 games
This index links to every platform the catalogue covers. The largest shelf by far is MS-DOS with 22,413 titles, 7,556 of which start in the browser through DOSBox. The 8-bit home computers follow: ZX Spectrum holds 5,240 games with 4,436 playable, and the Commodore 64 770 games with 570 playable. Coin-op arcade boards run under MAME — 805 titles, 440 of them playable — and the Sega Mega Drive shelf carries 556 games with 374 ready to run.
Which shelves you can play, and which you can only read
Not every platform here is an arcade. Nintendo 64, Game Boy, MSX and Amiga are reference archives: each game page gives you screenshots, developer, publisher, year and series, but no ROM, because most of those libraries are still commercially sold. Out of 37,331 catalogued games, 13,630 actually run, and nearly all of them sit on the DOS, arcade, Spectrum, C64 and Atari 2600 shelves. If you came to play, start there. If you came to check who wrote a game and when, the archive shelves are the better tool.
Every platform page carries a short history of the machine, its hardware specification and filters by genre and year — so you can pick the computer or console you grew up with instead of learning emulator names.
