Atari800 emulator
Atari800 emulator 2.1.0 RELEASE 3 for Samsung TV
Contents
What is it?
This is fully-functional Atari XL/XE (8-bit) emulator for Samsung TV-sets equipped with Content Library feature. Using this emulator you can run your favourite 8-bit software for Atari computers on your Samsung TV-set. This emulator has been ported from open-sourced Atari800 available earlier for many operating systems. This port is based on SDL version of the original.
Requirements
- Samsung TV set with Content Library feature (like LE40B650)
- USB keyboard (although many functions are available through remote control)
- ca. 2 MB of flash memory for emulator files + additional space for Atari software
- ca. 50% of CPU power
How to start
Atari800 emulator can be downloaded from:
- Content Library Applications list
- or direct here
*** VERY IMPORTANT ***
First, you have to copy Atari ROM files (not included) on your pendrive. If you don't know how to dump ROM files from your Atari computer, then you can download Atari ROM files from: PC XFormer emulator
Then extract all *.ROM files into Atari800/ROM subfolder on your pendrive.
You need ATARIBAS.ROM, ATARIOSB.ROM and ATARIXL.ROM files in there.
You should see such Atari800 directory structure:
[..] [files] [..] (put Atari software files or disk images here) [ROM] [..] ATARIBAS.ROM ATARIOSB.ROM ATARIXL.ROM [DRV] [..] evdev.ko usbhid.ko atari800.png atari800.so clmeta.dat loader.so
You may copy Atari files (binaries, disk images) into [files] subdirectory. Create subfolders if you want to. Connect USB keyboard to your TV. You don't need to load HID modules, because emulator will load them for you. Insert pendrive with Atari800 folder into your TV's USB port, hit CONTENT (library) button, choose GAME, look for Atari800 and start. You may also copy it to the internal memory. You'll probably see SELF TEST screen first time. Please hit F1 key (MENU button) to configure or load a game or other tool.
You cannot use command line options as in classic Atari800 emulator. Command line options are not editable for user.

Joysticks
Apart from standard joysticks (handled by the SDL) up to two keyboard joysticks are supported. The keys used for joystick directions and the trigger can be freely defined in the config UI (Controller Config -> Define layout). Keyboard joystick emulation can be enabled/disabled in the Controller Config. By default, joy 0 is enabled and joy 1 is disabled (to not steal normal AWDS keys in the emulator).

numeric 8 - stick up numeric 5 - stick down numeric 4 - stick left numeric 6 - stick right right SHIFT - fire (trigger)
How to attach original Atari/Commodore joystick?
You can build a simple interface to translate original joystick signals to USB HID device commands. It requires some knowledge and is not very easy.
For more information you can check these websites: V-USB A Firmware-Only Driver For Atmel AVR Microcontrollers or USBjoy - V-USB.
In my opinion, the easiest way to connect Atari joystick is to attach it to the USB keyboard. How to do it? Open your USB keyboard, then locate PCB pins that are shorted by keyboard's keys. Search and choose 5 keys shorted to one common pin. In my keyboard, I found such keys: C, D, W, -, 2 and [ (even one extra key as you can see). Do not choose keys often used in games or operating system itself, like SPACE, ESC or ENTER.
Then connect this common pin to pin 8 of Atari joystick (DB9 male connector - pin 8). All other keys can be connected in any order to the Atari joystick pins: 1 (up), 2 (down), 3 (left), 4 (right) and 6 (fire). Then you have to configure your "keyboard" joystick in UI menu. That's all.
This is the whole thing made in 2-3 hours:
And this is the PCB itself (note that there are many different keyboards so there is no common schematic for every keyboard). Treat this description as an example. In your particular keyboard you have to use a piece of wire to test which PCB pins to attach to.
What is missing? You may add some protection circuits or devices (parts) to protect your keyboard's IC against electromagnetic fields or radio interferences.
Please don't use long cables to prevent troubles. Do not connect other devices than Atari joystick to your DB-9 connector.

Mouse
Paddles, Atari touch tablet, Koala pad, light pen, light gun, ST/Amiga mouse, Atari trak-ball, joystick and Atari 5200 analog controller are emulated using mouse.
USB mouse is supported but disabled by default. To enable mouse please select mouse mode in user interface menu.
Note that emulated mice like touch-tablet mice may not work.
Samsung remote control buttons
In general, prefered device is USB keyboard, but you can use remote control as well to emulate some Atari keys or call some special functions:
REMOTE KEYBOARD/FUNCTION ------ ----------------- POWER F9 (exit emulator) TV F7 (BREAK) 0...9 0...9 or ["],[A]...[I] or [-],[J]...[R] or [,],[S]...[Z],[.] PRE-CH letters/numbers mode for remote control keypad SOURCE LALT+G (screen width mode) CH.LIST LALT+C (cartridge management) MENU F1 (UI menu) FAV CH LALT+Y (select system) cursors cursors ENTER ENTER (RETURN) INTERNET F6 (HELP) TOOLS F1 (UI menu) RETURN ESC EXIT F9 (exit emulator) red F4 (START) green F3 (SELECT) yellow F2 (OPTION) blue F5 (RESET) VOL+/- master volume control MUTE mute/unmute sound TTX/MIX LALT+B (black and white mode) MEDIA P. LALT+O (sound settings) CONTENT F9 (exit emulator) INFO LALT+A (about emulator) GUIDE LALT+R (run Atari program) SUBT LSHIFT+F5 (cold RESET) REWIND BACKSPACE PAUSE CTRL+1 (Atari pause) FORWARD SPACE RECORD LALT+W (sound recording start/stop) PLAY F5 (START) Other buttons are unused or blocked.
(the image above is also compatible with version 2.1.0 R2 of Atari800 emulator)
How to exit emulator
By remote control: hit EXIT, CONTENT or POWER button or hit MENU button (UI menu), then select "Exit Emulator"
By USB keyboard: press F9 key or press F1 key (UI menu), then select "Exit Emulator"
Where to get Atari games (ROMs) from ?
First, use Google or other web search engine to look for them. There are many websites hosting ROM files for old machines.
Here is an example list of websites holding Atari ROM files:
ftp://ftp.pigwa.net ftp://atari.fornax.sk ftp://ftp.funet.fi http://vjetnam.hopto.org http://www.atari800.net http://www.atarimania.com
How to access external USB device (pendrive or HDD) ?
FOR ADVANCED USERS! YOU NEED TELNET ACCESS!
If you copied Atari800 emulator to the internal memory, you can access only internal files. But you can create a symbolic link that will allow you to acces external directories like USB device. Run telnet, login to your tv, then type:
cd /mtd_tlib/GGame/Atari800/files mkdir USB1 ln -s /dtv/usb/sda1 USB1
NOTES: verify if you have /mtd_tlib/GGame/Atari800 directory with copied emulator files before. Check your external pendrive path (/dtv/usb/sda1 in this example). You can add more links (USB2 to /dtv/usb/sdb1 for instance). Links are permanent. To remove them, simply remove created subdirectories (by command: rm -r USB1).
Known bugs
- delayed sound - PC USB tablets (even in mouse mode) may not work - USB-to-PS/2 keyboard/mouse converters may not work with PS/2 devices (please connect USB keyboard or mouse directly or via USB hub) - limited access to pendrive when executed from internal memory - remote control buttons cannot be pressed simultaneously (quite obvious) - remote control buttons are not recommended for joystick's simulation - not all Atari software works well (common problem for all software emulators) - recorded WAV files or screen capture files cannot be deleted easily; they can be accessed using telnet or FTP, though - ROM memory failed in SELF TEST; this is normal for Atari800 - sometimes: abnormal termination on exit command called from "Crash Menu" - sometimes: emulator slows down and sound is broken; please restart emulator - sometimes: screenshots may not be made correctly - NTSC filter (when enabled) significantly decreases emulation speed
PLEASE KNOW THAT THIS EMULATOR HAS NOT BEEN FULLY TESTED! SOME BUGS STILL CAN BE UNKNOWN!
Common problems
PROBLEM:
SOLUTION:
Delete atari800.cfg configuration file or create pendrive again. Make sure that all system ROM files reside inside "ROM" subdirectory.
PROBLEM:
I cannot remove (old version of) Atari800 emulator from Content Library (internal memory).
SOLUTION:
Probably it cannot delete configuration file created later (.atari800.cfg). Use telnet command to remove the whole Atari800 directory with all files inside. For example:
rm -r /mtd_tlib/GGame/Atari800
and restart your TV.
PROBLEM:
USB keyboard or USB joystick is not working.
SOLUTION:
Turn off your TV, then turn it on again. USB keyboard or joystick must be initiated while drivers are loaded.
