The free Atari emulators listed on this page allow youto revisit those days using your modern computer, be it a PC, Mac or some other machine. They usually provide emulationfor a variety of Atari hardware, including joysticks, track ball, paddles, touch tablet, light pen, light gun, cassette recorder,floppy and hard disks. You will probably also need Atari ROMs which may or may not be provided forthe machines to use the emulator. If you are able to locate standard disk images for old Atari software, like games,these emulators will also be able to load them as though the images were normal disks in the floppy drive orcassette tapes in the recorder.
The emulator support TOS 1. At the time of writing, sound was not yet supported. GZ, and XFD. GZ disk image support, etc. You can save the current emulation stateas well as take screen shots with the emulator. When I am trying to play games like river raid and space invaders, I do not know what the start key for those games are. Please Help! Your email address will not be published.

Learn how your comment data is processed. Built-in ROM database with information partially compiled by RomHunter Getting Started Requirements The following sections outline the basic system requirements for running Stella under various operating systems.
General required for all versions of Stella SDL version 2. Other Stella is extremely portable, and in its lifetime has been ported to almost every platform where the SDL library exists. The Stella Team is interested in hearing about any problems you may encounter with diverse operating systems and CPU types.
Stella is distributed in both source and binary form. In general, you should always download and install the appropriate binary version. Compiling from source is only recommended for developers, or if the binary version doesn't work for some reason.
Once you have a Stella distribution you should follow the instructions for your operating system given below. Building and installing from source code See the developers build instructions at the Stella Development Page. Windows Binary EXE installer stella- release - arch.
Plugging a cartridge into the Atari allows the 's microprocessor to access the program stored on the cartridge. In a similar way you must "plug" a copy of a cartridge into Stella when you want to play it. A ROM image is a file, which contains the actual data and code read from the cartridge. There are several ways to obtain a ROM image of a cartridge:. Many homebrewers make their ROMs available too. Supercharger Cassettes Supercharger games were not stored on cartridges instead they were stored on cassette tapes.
The Supercharger also supported multi-loading, which allowed games to be broken into several segments and loaded at different times. This was useful for large games which had distinct parts such as role playing games.
Most of the available Supercharger ROM images are stored in bytes files. However, ROM images of multi-load games are sometimes stored in a set of byte files. The names of these files have a two character sequence number in them which indicates what load they are.
The sequence starts with zero, skips a few numbers and then increments by one. If an archive contains many such files, Stella will display a virtual filesystem with the contents of the archive. This can be then browsed like a normal directory. Other extensions are also possible, namely to force a specific bankswitch scheme. Normally, the bankswitching scheme for a ROM is determined automatically, or manually by setting a ROM property , and you never have to do anything yourself.
However, it is also possible to force the bankswitch type to use by adding a special filename extension. These extensions are listed in the ROM properties section under Cart. Note: These extensions are the same as those used by the Harmony Cart and Unocart and are not case-sensitive, so you can name your files and have them work across all applications.
Again, to be clear, this is only necessary when you want to override the default bankswitching scheme for a ROM. This will not normally be necessary. Commandline support is also available for those who want to use it. If this is your first time starting Stella, you may have to navigate to your ROMs.
You can change it later in the ROM Launcher dialog. At this point, you may want to set the locations for snapshot images. This is described in more detail in ROM Launcher.
These settings are optional, and can be left at the defaults if you won't be using snapshots in the ROM launcher. Note that some games require you to 'Reset' the console before you start playing. In this case, you need to hit the virtual reset switch, which by default is the F2 key. Also, some games may require that you press the joystick fire button to begin, which by default is the Left Control or Space key s , or button 0 on your joystick.
If a game uses a more complex controller, see Getting Started - Keyboard Layout for more information. To exit a game and re-enter the ROM launcher, press the 'Escape' key. Using the 'Search' textbox in the upper-right of the ROM launcher, the listing can be narrowed down, showing only the ROMs that match the pattern you enter.
While the file listing is in focus, you can type some characters, and the listing will 'jump' to the file that matches what you typed. This is case-insensitive. Hold down the Shift key on the first character to select directories instead. The delay between successive keypresses being treated as part of one word is controlled by the 'listdelay' option; see User Interface Settings to change this setting. Command Menu While playing a game, normally one would use the keyboard shortcuts for controlling the 'virtual' switches in Stella ie, the commands associated with the function keys as described in Getting Started - Keyboard Layout.
However, another alternative is available. This dialog contains a set of buttons that represent the same functionality as the function keys and display the current state. You may find this useful if you cannot remember all the function key events, or you wish to use Stella without a keyboard ie, in a standalone gaming system. This works for almost all dialogs. There is also a hotkey defined for help see Hotkeys. The Atari console controls and controllers are mapped to the computer's keyboard as shown in the following tables.
However, most of these events can be remapped to other keys on your keyboard or buttons on your joystick see Advanced Configuration - Event Remapping. The tables below show the default settings. If you use a different layout some keys may differ.
You can use the following layout image as reference where to find the US keys on your keyboard. Sega Genesis Controller cannot be remapped, always associated with joystick and Booster Grip controllers. These keys allow selecting and changing settings without having to remember the dedicated hotkeys.
Notes: Only available if UI messages are enabled. Currently not available settings are automatically skipped.
If a setting was previously selected via a dedicated hotkey, its value can also be directly changed with the global keys. Some Atari virtual controllers are simulated with more than one computer controller, and there are several special cases where controllers are active in certain modes only, as the table below shows.
In this mode, Stella automatically creates savestates in regular, user-defined intervals. At any time, the user can interrupt the current emulation and navigate back and forth within the saved timeline. This dialog is automatically entered when using one of the Time Machine hotkeys. The hotkeys continue to function within the dialog. The 'Time Machine' mode can be configured by the user. For details see Developer Options - Time Machine tab.
For a number of popular classic and homebrew games see High Scores - supported games this has been done already. To save a score, the High Score dialog can be opened by pressing 'Insert' any time while a game is played.
It will provide the current variation and score and allow the user to add this as a new high score. Of course this makes most sense when a game is over.
Note: In multiplayer games, only the score of the first player can be saved. For details how to configure high scores definitions for a game see High Scores Properties. Advanced Configuration The default options in Stella are meant to cater to as many situations as possible.
As such, you may never need to change many of its options. However, Stella is very configurable, and if you want to change its behaviour in some way, there's likely a configuration option to do so. The remainder of this lengthy section details every configurable option.
In addition to the built in ROM launcher, Stella can also be used from the command line assuming your operating system has a command line. Options '0' or 'false' indicates false, '1' or 'true' indicates true, others are self-explanatory :.
The following are useful to developers. Only use them if you know what you're doing! Note that in all cases, the values supplied to the arguments are not case sensitive. The following are almost all available in two sets, one for players prefixed by "plr. All settings can be changed within the integrated Options UI while Stella is running unless otherwise noted; some settings require an application restart.
Too aggressive settings for your combination of hardware and software high sample rate, low fragment size, low headroom, low buffer size may lead to audio dropouts whose effect may range from isolated popping artifacts to garbled audio. You can check the system log for related messages. Note that there are currently two separate event modes in Stella; emulation mode and user-interface UI mode.
Each mode has separate mappings, so for example while in emulation mode, the left arrow could mean 'joystick 0 left', while in UI mode it could mean 'move cursor left'. Emulation mode occurs whenever you're actually playing a game. UI mode occurs whenever a user interface is present ROM launcher, debugger, settings menu, etc. Click the 'Event Mappings' tab.
Here you can also filter the list of events by type. Select the event you want to remap and click the 'Map' button.
Now define the input: Either press a key, a modifier key Control, Shift Then that key combination or controller action will be bound to the selected event. Notes: If nothing seems to happen, either Stella can't see the input device, or the selected event doesn't support being remapped to the input device. The same input can be used for multiple controller types e.
If the same input is used again for the same controller type, the old mapping will be removed. Events which are available in both event modes can be remapped individually. Left and right modifiers are mapped separately when used alone. You can also: Cancel a remap in progress by clicking 'Cancel'. Note: Pressing 'ESC' will map that key, not abort the mapping. Erase all event's mappings by clicking 'Erase'. Reset the event to its default mapping by clicking 'Reset'.
Reset all emulation or UI event mappings to default by clicking 'Defaults'. The following screenshots illustrate the event remapping process: Finally there is a 'Combo' button in the 'Emulation Events' tab, accessible only when a Combo event has been selected from the list of events on the left.
Clicking 'Combo' will show a dialog similar to the following:. In this dialog, you can assign various events to the selected combo event. Note that this only assigns multiple events to the combo; you still need to map the combo event itself to some action, as described in the 'remap an event' section above. Several options are configurable in the ROM launcher.
Most of the options are self-explanatory, except for the 'ROM info width' and 'Image path Support is automatic, as long as your image directory contains snapshots in the appropriate format. An archive of updated snapshots is available on the Stella webpage.
This archive may be updated periodically as new ROMs are found, and also for each new release of Stella. Note that the snapshots can be any size e. This context menu contains the following items:. Selecting options from this dialog will cause all ROMs launched after that to use those properties you specify. The dialog box for this feature is as follows:.
The ROMs will then be renamed according to their internal properties. When the operation is complete, the number of ROMs that were renamed as well as ones that weren't will be shown. Stella can use up to two adaptors; any extra ones are ignored. Stelladaptor devices will be automatically detected and configured. The detection and configuration is as follows: The first device found will act as the left game port on a real Atari.
The second device found will act as the right game port on a real Atari. Any other devices will be ignored. There should be drivers for your serial convertor, which allow your particular operating system to 'see' the device configuring this is outside the scope of this document. Once your operating system properly detects the AtariVox, you will need to tell Stella which serial port it is connected to.
Note that you must use the entire name of the port as specified by your operating system. This is very useful in the testing stages of creating a new game, since writing to a real EEPROM many times will eventually wear it out. Several developer related options can be configured in the 'Developer Settings' dialog. Two sets 'Player settings', 'Developer settings' allow easy adjustment of all settings for different use cases playing or developing games at once.
Many more options are available for ROM developers, which are described in different sections of this manual, as follows:. Developer key-combo shortcuts, used to change TIA state dynamically ie, while the emulation is still running.
See Keyboard Layout - Developer Keys for more information. Commandline options influencing emulation state. This option can be enabled from the command line or using the Alt-L key combo, and is extremely useful for viewing the current scanline count and associated frames per second, bankswitch and display formats, etc.
Atari Label Maker. Produces authentic looking Atari Labels including the famous "Picture Label" using your own image and title. If you want to make arrows to point out things in a photo like the arrows you might see in magazines and Atari game manuals , there are two freeware programs that I know of with that ability:. Makes the kind of arrows you might see in an Atari game manual.
Select the Line Tool and click on the arrow checkbox. Makes arrows with larger heads. These arrows have nubs that you can grab to deform them. Great for making curved arrows.

For example, the wife of a guy I used to chat with online had severe mood swings which seemed to be caused by food allergies or intolerances.
She would became irrational, obnoxious, throw tantrums, and generally act like she had a mental illness. The horrid behavior stopped after she started taking a vitamin B complex.

It seems that most people should avoid wheat, not just those who have a wheat allergy or celiac disease. Negative ions are good for us. You might want to avoid positive ion generators and ozone generators.
Whenever I need a new air cleaner with negative ion generator , I buy it from surroundair. A plain old air cleaner is better than nothing, but one that produces negative ions makes the air in a room fresher and easier for me to breathe.
It also helps to brighten my mood. Never litter. Toss it in the trash or take it home. Do not throw it on the ground. Also remember that good people clean up after themselves at home, out in public, at a campsite and so on. Leave it better than you found it.
