New Hypseus with overlays and Singe support

LibRetro feature request from 2018:

Get Singe part of Daphne working #15

https://github.com/libretro/daphne/issues/15

[RustyMG]

@DirtBagXon
Hi all,
Been a long day and Im reading the forum posts when meant to be working.
Yes, I meant Singe!

I have read elsewhere that this is now working reliably with lots more laserdisc games.

This, along with a Sinden light gun would be an amazing combination!

@DirtBagXon this might be of interest for @lmerckx, who added daphne to recalbox.

Aha, that would be Singe 2 - which doesn't have Daphne support.

A whole different ball game.

However, Hypseus Singe does have psuedo support for many of the Singe 2 games too.

Ok, thanks I'll try and ping them.

Will drop this here, to show development through different stages:

Hello @DirtBagXon,

Thanks for your message and your work.
I'll have a look at it.

[lmerckx]

Hello @DirtBagXon,

I've started to test your development and it seems to work.
I also adapted my patches to support remapping of joystick axis (as it is done for buttons).

Mad Dog McCree is playable (memories, memories ... ). But does Singe support the joystick ?
For me, I can only move the target with the mouse but perhaps I broke something with my patch ...

Thank you.

[RustyMG]

This is excellent news!
A start, but a great start.

I believe the following games work on Singe?

Crime Patrol
Crime Patrol 2: Drug Wars
Mad Dog McCree
Mad Dog McCree 2: The Lost Gold
Ninja Hayate
Space Pirates
Time Gal
Time Traveler
The Last Bounty Hunter
Who Shot Johnny Rock
38 Ambush Alley
Blue Thunder
HydroSub 2021
Pops Ghostly
Sonic Fury

Aha, the infamous Daphne joystick support.

Singe has never supported joystick axis movement as far as the codebase says, button yes, but axis no.

The LUA game script interface for mouse movement is fairly simplistic:

void sep_do_mouse_move(Uint16 x, Uint16 y, Sint16 xrel, Sint16 yrel)
{
        static bool debounced = false;
        int x1 = (int)x;
        int y1 = (int)y;
        int xr = (int)xrel;
        int yr = (int)yrel;

        // Not sure what's wrong here.  I think things are getting started before Singe is ready.
        if (!debounced) {
                debounced = true;
                return;
        }

        x1 *= g_sep_overlay_scale_x;
        y1 *= g_sep_overlay_scale_y;
        xr *= g_sep_overlay_scale_x;
        yr *= g_sep_overlay_scale_y;

        sep_call_lua("onMouseMoved", "iiii", x1, y1, xr, yr);
}

Whereas the joystick is referenced in Daphne I/O based on SDL events:

// processes movements of the joystick
void process_joystick_motion(SDL_Event *event)

I believe in the past people may have used joystick to mouse movement wrappers as a work-a-round.

I will take a look to see if I can link these differing elements of the codebase, but suspect it's not as easy as it looks or sounds.... inherited issue.....

Could an analogue joypad be "fooled" into operating as a mouse as a work around ?

I think the package 'xserver-xorg-input-joystick' might be worth playing around with.

DESCRIPTION
joystick is an Xorg input driver for controlling the pointer with a joystick device.
Use this driver, if you want to
- generate cursor movement, perform button or key events to control desktop and applications
- generate cursor key events for playing legacy games, that have no native joystick support

Do not use, if you want to
- play games, that have native joystick support
- use XI2 applications. The evdev(4) driver will suffice for those in most cases.

You may mix above scenarios by setting the device floating. The driver reports relative cursor movement, button and key events, as well as raw axis values through valuators.

[DirtBagXon]

Ok,

I have this working fairly simply, although I have to say playing Maddog with a joystick is a whole different experience.

Firstly, you need to set the joystick buttons, details are in hypinput.ini file supplied in repo, but I will outline here:

Remember hypseus uses SDL2 keycodes, so porting previous Daphne configs won't work:

SDL2 keycodes are here: https://github.com/DirtBagXon/hypseus-singe/blob/master/doc/keylist.txt

To figure what joystick button to program:

jstest /dev/input/js0

Minimal config for Maddog:

[KEYBOARD]
...
KEY_COIN1 = 53 0 7
KEY_START1 = 49 0 8
KEY_BUTTON1 = 1073742048 0 3 <- Reload
KEY_BUTTON3 = 32 0 1         <- Shoot
KEY_QUIT = 27 0 4
...
END

Joystick config:

# The third number is the joystick button code (or 0 for "none")
# Since 0 is reserved for special meaning, joystick button 0 is
# identified as 1 here.  Button 1 is identified as 2, and so on.

That deals with the buttons, so to the axis:

There are a few routes but this was most simplistic, using qJoypad:

apt-get install qjoypad

Then a simple config to map joystick movement to mouse movement:

cat .qjoypad3/SINGE.lyt 

Joystick 1 {
        Axis 1: gradient, maxSpeed 10, mouse+h
        Axis 2: gradient, maxSpeed 10, mouse+v
}

Load and daemon'ize on game startup with:

qjoypad -t SINGE

@lmerckx

Ok, so I have added joystick support to Singe...

Could I ask you to test this out ?

git clone --single-branch --branch singe-joystick https://github.com/DirtBagXon/hypseus-singe.git

It takes additional arguments of:    -js_range <1-15>   to alter joystick sensitivity: defaults to '5' currently.

BTW: Maddog will look optimal with the following argument too:   -blend_singe_sprites

[DirtBagXon]

@DirtBagXon said in New Hypseus with overlays and Singe support:

BTW: Maddog will look optimal with the following argument too:   -blend_singe_sprites

-blend_singe_sprites now changed to -blend_sprites

Option has become game (singe) specific....

 

Also just to clarify, joystick support is now within Hypseus Singe in the branch link above.

It does not need the wrapper options discussed above.

[lmerckx]

Great ! Thanks @DirtBagXon .
I will test that ...

If the joystick is supported by linux, and you can see axis movement with jstest: -

Yes it should now work in the main repo from v2.4.2

 

I believe the following games work on Singe?

Crime Patrol
Crime Patrol 2: Drug Wars
Mad Dog McCree
Mad Dog McCree 2: The Lost Gold
Ninja Hayate
Space Pirates
Time Gal
Time Traveler
The Last Bounty Hunter
Who Shot Johnny Rock
38 Ambush Alley
Blue Thunder
HydroSub 2021
Pops Ghostly
Sonic Fury

Yep all these work.... plus....

TimeGal (Singe 1 and 2 versions)
Ninja Hayate
Starblazers
Platoon (Singe 2)
Freedom Fighter
Fire and Ice (Singe 2)
Dragon's Lair 2 Enhanced Edition (Singe 2)

Not to forget all the Daphne games...

@DirtBagXon I've tested the joystick patch.

It works but, indeed, targeting with the joystick is really hard !
The mouse (touchpad for me) is really simplier.

But anyway, I will post a merge request to integrate your project in Recalbox.

Many thanks,

I have been told that it works well with lightguns and trackball setups, but I don't have the ability to test these.

It basically uses SDL2 LEFT, RIGHT, UP and DOWN keycodes, so provided the connected device send these (joysticks, trackb***s, lightguns and indeed keyboards) all do so technically it should work.

The patch is now in the main master and RetroPie branches, so no need to use the sub-branch above.

A few others have now tested with good responses, so thank you for the idea of adding it

It does add a new element of difficulty to the games, but a few of the testers have added it to arcade cabinet conversions (which obviously don't have mice), and are giving very positive feedback......
