Little Daphne emulator help

DingoAce10

Got a couple questions about the Daphne emulator. I am running it on the Pi 3b using the X-Arcade tank stick. I have read the wiki on this site about the daphne emulator and have everything running with a couple small problems.

Controls:
The joystick on the tankstick works fine along with all of the buttons (coin, start, exit...etc) except for the most important one. The "action" button (Dragon's lair sword, cliff hanger jump...) doesn't work for me. I have set it to every button on the tankstick and none of them work. I have run the "jstest" program, the buttons respond just fine. I set the last number in the config file to the correct button (button # +1), but still doesn't seem to work.
Anything thing else I can look at to get it to work?

Black screen on Space Ace:
I have Dragon's Lair 2 and Cliff hanger running fine. But no matter what I do space ace just goes to a black screen after processing the video files. I have read the other posts about "black screens" on the forum and removed the .dat files. I have tried a command that was mentioned to set all the directory's permission to the "pi" user, but still can't seem to get it to load correctly.
Is there something else I can try? Am I just being too impatient and need to wait a long time for the video files to process? The other 2 games too under a couple minutes to process.

Thanks very much in advance!

What does your dapinput.ini file look like, have you tried the below? Did the tank stick work without any config changes (minus action button)? Also with the default controls setup does a keyboard work for the action button? (I think its ctrl or space bar).

KEY_BUTTON1 = 0 0 1

@DingoAce10 Regarding controls, for what it's worth, I'm having the same problem now.

I updated to latest code about a week ago, and since then, the Action button does not appear to be mappable. My dapinput file has not changed in a year, and controls were working perfectly with a Playstation 4 controller prior to the update.

Like you, everything else works except for the Action button.

Anecdotally, it seems to be a new(er) bug, but I wouldn't cry wolf just yet. I did devote a few hours to solving this without finding a solution.

Okay, regarding controls --
I'm using a PS4 controller, and updated to latest Daphne Source (after a Retropie Script update). I know you're using a different controller, but here is what I have in dapinput.ini for my PS4 controller. These settings now work perfectly for me. Remember, the first two sets of numbers are keyboard codes and the 3rd number maps to a controller button "+1" -- so button "0" would read as "1"... A "0" means, inactive button (more explanation below the output):

[KEYBOARD]
KEY_UP = 273 114 0
KEY_DOWN = 274 102 0
KEY_LEFT = 276 100 0
KEY_RIGHT = 275 103 0
KEY_BUTTON1 = 306 97 1
KEY_BUTTON2 = 308 115 4
KEY_BUTTON3 = 32 113 2
KEY_START1 = 49 0 9
KEY_START2 = 50 0 0
KEY_COIN1 = 53 0 10
KEY_COIN2 = 54 0 0
KEY_SKILL1 = 304 119 3
KEY_SKILL2 = 122 105 5
KEY_SKILL3 = 120 107 6
KEY_SERVICE = 57 0 0
KEY_TEST = 283 0 0
KEY_RESET = 284 0 0
KEY_SCREENSHOT = 293 0 0
KEY_QUIT = 27 113 11
END

So anything with a "0" at the end deliberately does not map to a button.

KEY_BUTTON1 maps to the Dragon's Lair Sword. The number "1" in my configuration maps to the PS4 "X" button (button code 0 + 1 = 1). Games that require more buttons (KEY_BUTTON2 and KEY_BUTTON3) map to PS4 "Square" (code 4) and "Circle" (code 2) buttons respectively.

KEY_SKILL1, 2 and 3 map to the difficulty settings for games like Space Ace (where you could choose "Cadet", "Captain" or "Space Ace"). These map to Triangle, Left Bumper and Right Bumper respectively.

I use the PS4 logo button to exit (code 11)

Hope this is helpful for your controller issues.

this subject keep on reapearing i put a pull request in for this on retropies github and it was ignored for months so i just closed it. if you want to fix it compile it from my repo like this. it will also fix analog joystick controls up for directions to be used.

cd /home/pi/RetroPie-Setup/
git clone https://github.com/grant2258/daphne-emu.git tmp/build/daphne
sudo ./retropie_packages.sh daphne depends
sudo ./retropie_packages.sh daphne build
sudo ./retropie_packages.sh daphne install
sudo ./retropie_packages.sh daphne configure
sudo ./retropie_packages.sh daphne clean

For those still having the problem. I updated the Daphne emulator from the binary and everything is now working correctly.

@grant2258 You wouldn't want to add the much-needed joystick selection (i.e. other than /dev/event0) to Daphne by any chance? 😌

Well its using sdl I know it isint quite what you asked for but you can changed this one line here to change the joystick for your setup.

https://github.com/grant2258/daphne-emu/blob/fd017595886a6cf55b412c8afd2ca29bb4e4d7e6/src/io/input.cpp#L303

SDL_JoystickOpen(0) is default change t to which one you want for your setup SDL_JoystickOpen(1) ect and just compile the source.

I dont have any plans to change daphne much but its easy enough to set here. I would need to look at the source and add another command line option to do that as the cfg file is read after the joystick init ill leave it in a todo bucket but this should let you change it for now.

Clyde

@grant2258 Thanks! I'll try that. 😊

Clyde

@grant2258 Er … sorry, how do I compile from your repo? sh ./buildme.sh fails, see here for the output. I tried on Kubuntu 18.04.

grant2258

the retropie instructions are above your using retropie use the retropie build scripts. Are you using retropie on x84/64 bit ?

Clyde

@grant2258 Yes, at least for the test above for speed reasons. But I finally plan to compile your daphne fork on my Pi 3b. Sorry, I missed the instructions above. As I understand them, they clone your repo directly to the temp dir Retropie is using for its "installation from source", and then invoke the Retropie installation script for all necessary steps, right?

Do I have to modify your instructions for my 64 bit system? (I can't test it before tomorrow.)

grant2258

never tried compiling this code in 64 bit to be honest i would need to compile it locally to test

Clyde

@grant2258 I did compile your version with SDL_JoystickOpen() set to 1 on my Pi by now. But alas, I can't control the game with my joysticks connected via two DragonRise encoders. For some months now (and maybe since I experimented with lr-daphne), in Dragon's Lair 1+2 and DLE 2.1, any movement from one of the sticks will freeze the video in the games' attract mode as well as in a running game. I can control the games via keyboard, however. Since this happens with your fork as well as the source and binary versions from Retropie, I'll have to fix that before trying to change the joystick detection in your version.

I don't want to hijack this thread with this problem, so I will open another thread about it (not now, since I have to leave soon). If you've any quick idea what may be wrong with my Daphne setup that worked flawlessly before, you may still answer here until I've opened a new thread.

grant2258

Well it could be something in your setup daphne by default uses the first joystick found. I could be any joystick number if you have more setup or custom settings for joysticks. You would need to add extra info to see what joystick sdl is using in daphne. Your problem sounds more liek a config problem or the first joystick isint you dragonrise

Clyde

@grant2258 Thanks for the tips. I'll cobble something together when I have time to collect the necessary information.
