Atari 5200 (Experimental)
Warning
The Atari 5200 application is currently designated as an experimental application.
This designation has been applied due to the following:
- Single player only (core does not support second fire or keypad for player 2)
- Does not support newer homebrew (unsupported mappings in core)
- Analog quirks (holding analog stick in a direction prior to level starting causes odd behavior: Centipede, Missile Command, probably others)
By default, Experimental applications are not displayed in the webЯcade player or feed editor.
To enable the Atari 5200 application, refer to the advanced settings sections of the player (player advanced settings) or editor (editor advanced settings).
Overview
The Atari 5200 application is an emulator for the Atari 5200 game console.
BIOS File (Optional)
In addition to Atari 5200 ROM files, an optional Atari 5200 BIOS (typically named 5200.rom) can be specified globally within the feed (See the Feed Properties Dialog and Atari 5200 Feed Properties sections).

to another Atari 5200 application (different emulator implementation) if it is determined to be a
more appropriate default.
