jfroco

UPDATE2

Script to autoconfigure the buttons using Retroarch configuration
Ability to define joysticks numbers
You can configure second axis ID

UPDATE

Repository: https://github.com/jfroco/atari800-rpi

Features

This is a port of Atari800 with focus on emulating Atarin 5200 that adds:

Full Joystick support for RetroPie
Menu navigation using joystick
Joystick Button configuration: trigger1, trigger 2 (Moon Patrol and H.E.R.O.!), asterisk and hash.
Supports hat and axis for joysticks
Use second analog stick in first as second player stick: Robotron and Space Dungeon!!!

(Only player1)

Hotkeys:

SELECT + START to exit emulator
SELECT + * (X): Emulator Menu
SELECT + # (Y): Reset

Use joystick to navigate the emulator MENU plus Trigger 1 (A) to accept and Trigger 2 (B) to go back.

Hint: If the emulator asks for Cart type select one of these using joystick + trigger 1:

Two chip 16 KB 5200 cartridge <- for 16KB roms (games)
Standard 32 KB 5200 cartridge <- for 32KB roms (games)
Bounty Bob 40 KB 5200 cartridge <- for the great Bounty Bob strikes back! game

Installation:

New parameters in /home/pi/.atari800.cfg :

SDL_JOY_0_SELECT=8 <-- button ID
SDL_JOY_0_START=9 <-- button ID
SDL_JOY_0_TRIGGER1=1 <-- button ID
SDL_JOY_0_TRIGGER2=2 <-- button ID
SDL_JOY_0_ASTERISK=0 <-- button ID
SDL_JOY_0_HASH=3 <-- button ID

See sample.cfg

Use jstest application to get the button IDs for your joystick.

Compiled and tested on RETROPIE 3.6 using a RPI2:

cd src
autoreconf -v
./configure --target=rpi
make clean
make

Replace atari800 in /opt/retropie/emulators/atari800/bin/ with the new generated executable

Check emulators.cfg for recommended configuration

Compiled version:

cd /opt/retropie/emulators/atari800/bin/
sudo cp atari800 atari800.original
sudo wget https://github.com/jfroco/atari800-rpi/blob/master/atari800?raw=true -O atari800
sudo chmod +x atari800

Original Post

I was trying the Atari 5200 emulator in RetroPie, and one thing that bugged me was that the second button (trigger) of the gamepad is the shift key... not a joystick button...so I couldn't play my favorite Atari 5200 game: Moon Patrol!!! (it uses two buttons: fire and jump), another thing was that my Hori PS3 mini fighting stick didn't work as the stick is registered as a hat not axis... and the last thing... I had to use the keyboard to start (F4) a game and to leave the game (F9)...

So... I pick my Language C book and after a couple of hours I added all this features to a new version of Atari800...

1.- New config file

Edit your /home/pi/.atari800.cfg to add this new parameters:

SDL_JOY_USE_HAT=1 <= If you want to use a stick with hat instead of axis
SDL_JOY_0_SELECT=8 <= button id for Select (use jstest to get the button id)
SDL_JOY_0_START=9 <= button id for Start (use jstest to get the button id)
SDL_JOY_0_TRIGGER1=2 <= button id for Trigger1 (use jstest to get the button id)
SDL_JOY_0_TRIGGER2=1 <= button id for Trigger2 (use jstest to get the button id)

Press SELECT+START to exit the emulator (go back to EmulationStation)

2.- Replace executable

Replace old executable with new one :
** This is not valid anymore **
cd /opt/retropie/emulators/atari800/bin/
sudo mv atari800 atari800.original
sudo wget https://dl.dropboxusercontent.com/u/4281970/atari800/src/bin/atari800
sudo chmod +x atari800

3.- Change the cart-type

I recommend using 32KB roms (games) and set the cart-type in emulators.cfg

Edit /opt/retropie/configs/atari5200/emulators.cfg

Use this line:
atari800="/opt/retropie/emulators/atari800/bin/atari800 -5200 -cart-type 4 -cart %ROM%"

If the cart is the wrong type you will have to select the right one.

This is a beta version so I really need your feedback...

To do:
Map # and % to gamepad buttons
Implement second player
Analog controls? => Not sure yet..

Any chance of you share the source instead, I also use a linux pc along with my pi.

Hi

Of course...

Best regards

mediamogul

This is fantastic! Thank you.

dabone

I had issues compiling your code under ubuntu.

You have used C++ comments of // in a c project.

C needs the /* to begin a comment and */ to end it.

After I changed the comments in input.c, it compiled.

BuZz

Rather than forking it - if your changes would benefit other platforms it would be a good idea to feed any patches upstream - the emulator is still in development.

dabone

I'd like to see definable joysticks.
I have custom compiled versions on my pi, because I have 2 xbox 360 contollers, and also 2 db9 joysticks.
I also have 1 other standard joystick, that is mapped as /dev/js0.
So for the atari800 emulator, I use joysticks 1 & 2 for xbox wireless, and 3 & 4 for original atari controllers.

(Now if I can remember where I made that change in the source...)

Later,
dabone

Update in the original post....

Full Joystick support for RetroPie
Menu navigation using joystick
Joystick Button configuration: trigger1, trigger 2 (Moon Patrol and H.E.R.O.!), asterisk and hash.
Supports hat and axis for joysticks
Use second analog stick in first as second player stick: Robotron and Space Dungeon!!!

@dabone Thank you. I replaced all // comments
@BuZz I would love to do, I'll try to do it next week

Update 2...

Script to autoconfigure the buttons using Retroarch configuration
Ability to define joysticks numbers
You can configure second axis ID

Autoconfiguration

You can auto-configure the first joystick to use the current joystick in EmulationStation/Retroarch:

cd /opt/retropie/emulators/atari800/bin/
sudo wget https://github.com/jfroco/atari800-rpi/blob/master/atari5200.py?raw=true -O atari5200.py
sudo chmod +x atari5200.py

Now edit your /opt/retropie/configs/atari5200/emulators.cfg, it should look like this:

atari800="/opt/retropie/emulators/atari800/bin/atari5200.py; /opt/retropie/emulators/atari800/bin/atari800 -5200 -cart-type 4 -cart %ROM%"
default="atari800"

Now everytime you start a game, the atari5200.py script will configure the atari800 emulator joystick for you, respecting current EmulationStation button configuration.

See emulator.cfg in https://github.com/jfroco/atari800-rpi

@jfroco

This just keeps getting better. Great work on all this.

future.child

For what it's worth, i have made a few changes to the jfroco version.
This version handles button support for the option, start and select keys found in the 800 / XL emulator.

The Binary may be found here : https://github.com/futurechild/atari800-rpi/raw/master/atari800
There is a new parameter in atari800.cfg : SDL_JOY_0_OPTION=4 <-- button ID

lakindc

@future.child I Installed the futurechild vesion and it works great. . .Except the screen is smaller. . .Is this a setting somewhere??

future.child

@lakindc I remember having this problem too but am unsure what i did so solve it.
I currently have 4:3 fullscreen emulator with a black bar left and right to fit my 16:9 screen.

Could you have a look at "video mode settings" in the menu under "Display settings" inside the emulator ?
Fullscreen should be set to "No" and i have resolution set to "640x480".

These are my current settings in the atari800.cfg file :
DEFAULT_TV_MODE=PAL
COLOURS_PAL_GAMMA=0.3
ARTIFACT_NTSC=NONE
ARTIFACT_PAL=NONE
ARTIFACT_NTSC_MODE=0
VIDEO_FILTERING=1
VIDEO_ZOOM=1.00

You can also check if the video mode is correct in the launcher (when launching the emulator you should get a message "press a button to configure"), mine is set to 1920x1080 @ 50 Hz 16:9.

Hello all,

I've downloaded @future-child 's version and It works except for the fact I cannot seem to figure out my button mapping situation. I'm using a Wi u controller that works great with emulationstation.

I am using the emulator for Atari 800 (not xl/xe) emulation, not for 5200 games as is on this thread. But its the same emulator so I wouldn't see a problem

Here is my atari800.cfg file pertaining to button mapping:

SDL_JOY_0_ENABLED=1
SDL_JOY_0_LEFT=260
SDL_JOY_0_RIGHT=262
SDL_JOY_0_UP=264
SDL_JOY_0_DOWN=261
SDL_JOY_0_TRIGGER=305
SDL_JOY_1_ENABLED=0
SDL_JOY_1_LEFT=97
SDL_JOY_1_RIGHT=100
SDL_JOY_1_UP=119
SDL_JOY_1_DOWN=115
SDL_JOY_1_TRIGGER=306
SDL_JOY_0_SELECT=8
SDL_JOY_0_START=9
SDL_JOY_0_TRIGGER1=2
SDL_JOY_0_TRIGGER2=1
SDL_JOY_0_ASTERISK=3
SDL_JOY_0_HASH=0
SDL_JOY_0_SECOND_AXIS=2
SDL_JOY_0_INDEX=0
SDL_JOY_1_INDEX=1

My 'Start' button works like you hit the 'H' button which pauses emulation. very strange . I went thru button configuration twice so I'm prettiy sure I have all the buttons defined within emulation station.

The new version of atari800 does let me exit out of a game (no more F9!) but, I cannot start a game without 'F4'

Does anyone have a working atari800.cfg file I can use?

A side note - I have to use ATARIOSB.ROM as my games will crash (Galahad and the Holy Grail) if I don't use the early Atari800 ROM. XL/XE crashes the game after killing the 3rd knight every time :(

Thanks for any help you guys can give (newbie)

Veramacor

OK, I copied the file from @future-child github directly and I'm not running with the start!

1st problem solved.

Now I am seeing The small screen issue too. if @lakindc , if you can tell me how you fixed that issue think I am in in business!

All except for 'SELECT' and 'OPTION' buttons

Thanks for letting me bounce my head around

Veramacor

Ok Optioni/Select buttons were good all the while. I used jstest /dev/input/js0 to discover that

SDL_JOY_0_OPTION=4 is mapped to the Left Shoulder button

Last Post from me - I will stop thinking out loud on the forum! Just looking for the small screen size resolution

and I am golden

Veramacor

I LIED and I'm sorry for that. I figured it out. SO I will post for those who are going to use this wonderful version of atari800:

VIDEOMODE_WINDOW_WIDTH=336
VIDEOMODE_WINDOW_HEIGHT=240
VIDEOMODE_FULLSCREEN_WIDTH=640
VIDEOMODE_FULLSCREEN_HEIGHT=480
VIDEOMODE_WINDOWED=0

The Key setting is the last line is set to:
VIDEOMODE_WINDOWED=1

And Indeed It makes sense as :
VIDEOMODE_WINDOW_WIDTH=336
VIDEOMODE_WINDOW_HEIGHT=240

becomes the new screen size.

Hey guys - thanks for all your help! Special thanks to both @jfroco and @future-child for their efforts!

future.child

Thanks @Veramacor , This video issue has been in the back of my mind since @lakindc's post but was unsure of it's cause.
I have updated my sample.cfg to include these videomode settings.

If you use a program called Altirra and load your 5200 roms, you can then save them with a header that will designate how the Pi emulator should load the game. Then if you remove the part of the emulators.cfg file that references cart type 4 and load the games normally they will all load without that screen asking you what type of cart the game is. :)

I would share mine, but without even reading the rules here I'm sure that's not allowed. It's really easy once you figure it out, and it doesn't take all that long since the 5200 library is so small.

I could post instructions on how to do this if anyone is interested.

Used2BeRX

Could somebody explain to me how the Robotron controls are supposed to work? I've got everything else working now, but the Robotron controls do not function for Robotron or Space Dungeon. Thanks!
