New Hypseus and lr-Daphne to add on Retropie-Setup

DirtBagXon

Ok, so I have located the commit that causes the issue, it was from 2.0.15:

https://github.com/libsdl-org/SDL/commit/e87c7940f59db12670089a4ed79c91dfbca92b33

If I revert out this "fix" on SDL 2.0.21, i.e. HEAD of libsdl-org/SDL, it all stills works as expected.

Executing: /opt/retropie/emulators/hypseus/hypseus.sh "/home/pi/RetroPie/roms/daphne/dle21.daphne"

So this detection is obviously not optimal in the the 32bit RetroPie environment. Are you guys able to offer a correction ?

I am no dev of SDL, but I see you guys have some experience on the local patches of SDL.

Wondering how to proceed on this ?

Not sure what correction could we add - the RetroPie environment is just a plain Raspbian Lite (Buster), using the default GL libraries/drivers provided by the OS. Is there any test - from one of the ones provided by SDL - that would help reproduce the bug ?

For now we rolled back the 2.0.20 upgrade (due also to https://retropie.org.uk/forum/topic/32209/), so this issue will not affect any more user for now.

Yeah, I was hoping you wouldn't say that :)

I'm not sure where to go from here. The aarch64 version works obviously with this "fix" and doesn't see the CPU utilisation or video stuttering. So maybe this is a 32bit SDL bug. I am nowhere near the pay-grade to talk to the SDL guys on this topic,

Nothing that looks relevant to me unfortunately...

Ok, but I'm sure this will come up again. I guess we may just need to pull back the package at that time until RetroPie makes the jump to aarch64.

The "alternatives", one of which is full 64bit, aren't seeing the issue. The other is 32bit, but using a different drivers I believe, is stating they are not seeing the issue, but I am continuing to investigate on that side too.

Edit: From an old SDL dev - "SDL people won't do a fix for 32bit" - guess I'm screwed...... lol

The difference between 32/64 is that there are no legacy BRCM drivers for 64bit, regardless of platform (Pi3/Pi4). I don't think it's a 32bit vs 64bit thing, more likely a legacy GLES vs Mesa (mainline) GLES driver thing.

The other is 32bit, but using a different drivers I believe, is stating they are not seeing the issue, but I am continuing to investigate on that side too.

Yes, it's the legacy Broadcom drivers vs the Mesa driver (enabled with the kms overlay). The Mesa drivers are the default in Bullseye, so that may explain why some users may not see the issue, even on 32bit.

EDIT: since the bisected commit points to changes in SDL_CreateTexture, is there a specific code path in Hypseus where this gets used and causes the issue ? I haven't checked the code, so I don't know wether there's multiple uses of SDL_CreateTexture.

Ok, that makes sense. See you do know more about SDL than I.

So RetroPie uses the Legacy drivers ?

Are there any public intentions on a move from this ?

I can explore that, but there are two pixel formats that are tied into the Daphne VLDP codebase and overlays, YUV and 8-bit.

SDL_PIXELFORMAT_YV12
SDL_PIXELFORMAT_RGBA8888

I have looked at these in the past and they appear fairly ingrained to the legacy codebase.

Fairly basic as far as pixel formats go...

It uses the RaspiOS's Buster default - on Pi3 and earlier it's the 'legacy' drivers, on Pi4 is the MESA drivers. In RaspiOS Bullseye, the default is MESA drivers only.

Are there any public intentions on a move from this ?

We'll add support for RaspiOS Bullseye, but we'll see why the pixel format detection doesn't work with the legacy driver.

Thanks for looking into this.

There is definitely a huge CPU utilisation jump with that commit. I'm not certain what interest the SDL devs are gonna have in fixing legacy driver issues in mainline, if the overall performance is beneficial elsewhere...

Ok, gottit.

Ok, now seen the correct #issue, not the one in libsdl-org.

So is this issue relating to Aleph One Marathon and eduke32 also ?

No, that's a different problem related to the GL renderer chosen by default (https://github.com/libsdl-org/SDL/issues/5348).

Thanks @mitu for all the help in tracking down the SDL2 regression. I will try and commit the "work-a-round" shortly to the main branches.

As this regression has pretty much reduced the chances of getting ActionMax working effectively with SDL2 on the Pi, I have been working on a little side project.

An "unofficial" RetroPie scriptmodule that uses the SDL1 version of Singe packaged up specifically for ActionMax. SDL1 had better native YUV support so there is less overhead in handling this pixel format. This emulator also supports ABS mouse input , and integrated Sinden borders, for all the lightgun enthusiasts out there.

I have been running this on RPi3 RetroPie with no issues. Although this is SDL1 and has all the inherent issues of this version.

Users with 4:3 monitors may find -ignore_aspect_ratio will provide help in using the full screen real estate.

The intention was to use this Daphne system actionmax emulator as a ROM specific choice in ES. It also uses the standard <game>.commands files for individual customization and has an independent config file, using SDL1 keycodes, as does the original Daphne.

ActionMax

I know a few users who have asked for this, so enjoy.

@dirtbagxon I tried installing the actionmax emulator, and I can boot games just fine. However I'm having a little trouble with the controls. The default singeinput.cfg does not work with my controller, but when I copied the config from my hypinput.cfg file in, the trigger buttons, quit button, and confirm buttons worked, but the direction buttons do not work so I am unable to move the cursor. This is my singeinput.ini (copied from hypinput.ini):

[KEYBOARD]
KEY_UP = SDLK_UP 0 0 -002
KEY_DOWN = SDLK_DOWN 0 0 +002
KEY_LEFT = SDLK_LEFT 0 0 -001
KEY_RIGHT = SDLK_RIGHT 0 0 +001
KEY_COIN1 = SDLK_5 0 9  #SELECT
KEY_COIN2 = SDLK_6 0 0
KEY_START1 = SDLK_1 0 10  #START
KEY_START2 = SDLK_2 0 0
KEY_BUTTON1 = SDLK_LCTRL 0 1  #B
KEY_BUTTON2 = SDLK_LALT 0 3  #Y
KEY_BUTTON3 = SDLK_SPACE 0 2  #A
KEY_SKILL1 = SDLK_LSHIFT 0 4  #X
KEY_SKILL2 = SDLK_z 0 5  #L
KEY_SKILL3 = SDLK_x 0 6  #R
KEY_SERVICE = SDLK_9 0 12  #L3
KEY_TEST = SDLK_F2 0 0
KEY_RESET = SDLK_0 0 13  #R3
KEY_SCREENSHOT = SDLK_F12 0 0
KEY_QUIT = SDLK_ESCAPE 0 0
KEY_PAUSE = SDLK_p 0 0
KEY_CONSOLE = SDLK_BACKSLASH 0 0
KEY_TILT = SDLK_t 0 0
END

Unless I'm misunderstanding and this emulator is meant for mouse support only, in which case I apologize in advance.

Good to hear the installation went well.

This is old SDL1 tech - what the Pi likes it would seem :)

The game was mouse (or lightgun) only I'm afraid. On Hypseus I added the ability to use the joystick as a mouse. If was fun but was never really a playable option (Anyone disagree?). If enough people really think it's worth while I can take a look at porting these changes in, but this is a different, and much simplified version of the INPUT system in SDL1, and the original Daphne code.

https://www.daphne-emu.com:9443/mediawiki/index.php/Input
https://www.daphne-emu.com:9443/mediawiki/index.php/KeyList

In referring to that, your singeinput.ini won't work. It needs to use the simplified (original Daphne style) SDL1 config. MACROS and direction etc were all additions I made to Hypseus (and SDL2) . I have added your js buttons to what I think should work for you:

[KEYBOARD]
KEY_UP = 273 0 0
KEY_DOWN = 274 0 0
KEY_LEFT = 276 0 0
KEY_RIGHT = 275 0 0
KEY_BUTTON1 = 306 0 1
KEY_BUTTON2 = 308 0 3
KEY_BUTTON3 = 32 0 2
KEY_START1 = 49 0 10
KEY_START2 = 50 0 0
KEY_COIN1 = 53 0 9
KEY_COIN2 = 54 0 0
KEY_SKILL1 = 304 0 4
KEY_SKILL2 = 122 0 0
KEY_SKILL3 = 120 0 0
KEY_SERVICE = 57 0 12
KEY_TEST = 283 0 0
KEY_RESET = 284 0 13
KEY_SCREENSHOT = 293 0 0
KEY_QUIT = 27 0 0
END

Note: The keycode values between SDL1 and SDL2 are vastly different, however the js buttons numbering remains the same. So you can take the 3rd field value and copy them between configs, as indeed you did here. But not the others.

Joystick support has now been added for the target cursor.

If you update via RetroPie-Setup, it should start working :)

@dirtbagxon Thank you for the quick fix! Much appreciated!

I was able to get the five ActionMax games working on my Pi 4 (I had to tweak your instructions for running them because I have my roms loaded from an attached SSD and thus symlinks don't work, but I'm happy with my solution). They work fine in your new actionmax emulator, but in hypseus (latest source version), I have a minor issue. All five games have no score display. No matter what I do, the overlay shows "Targets Disabled" and never changes to the score display. The games run perfectly fine otherwise, and at full speed.

Yep, that's a demonstration of the issue with SDL2 on the Pi, the "Targets Disabled" message appears when SDL2 won't allow the YUV pixels on the Renderer to be read. It's just a courteous message I put there rather than erroring out. Perhaps I should now change it to say: "Use actionmax emulator" - lol

Note: ActionMax works fine with Hypseus on Desktop Linux, Pi aarm64 (KMS/DRM + MESA) and Windows. This is an issue with the Pi SDL2 libraries on 32bit and other mixes of Pi display drivers.

Hence the reason for this new "companion actionmax" emulator using old SDL1 :)

As we all adopt the new Pi5 - this will all go away..... hopefully.....

@dirtbagxon Understood. Thanks for the explanation!

problem horizontal axis right and left inverted

Re: New Hypseus and lr-Daphne to add on Retropie-Setup

I apologize if I re-open a topic that is perhaps clear to many but not to me. I state that I am using the Hypseus emulator on a raspberry pi 3 modB + with retropie 4.8.x. I have configured the keys in the hypinput.ini file in both / home / pi / RetroPie-Setup / scriptmodules / emulators / hypseus and in / opt / retropie / configs / daphne.
Everything works for me except that I have the right and left axis reversed, by physically turning the joystick up and down I have it in axis while right and left reverse. I changed the parameters as listed below I use DragonRise Inc. Generic USB Joystick input_device = "DragonRise Inc. Generic USB Joystick" input_driver = "udev"
input_vendor_id = "121"
input_product_id = "6"

[KEYBOARD]
KEY_UP = SDLK_UP SDLK_r 5 -2
KEY_DOWN = SDLK_DOWN SDLK_f 7 +2
KEY_LEFT = SDLK_LEFT SDLK_d 8 -1
KEY_RIGHT = SDLK_RIGHT SDLK_g 6 1
KEY_COIN1 = SDLK_5 0 9
KEY_COIN2 = SDLK_6 0 0
KEY_START1 = SDLK_1 0 10
KEY_START2 = SDLK_2 0 0
KEY_BUTTON1 = SDLK_LCTRL SDLK_a 2
KEY_BUTTON2 = SDLK_LALT SDLK_s 1
KEY_BUTTON3 = SDLK_SPACE SDLK_d 4
KEY_SKILL1 = SDLK_LSHIFT SDLK_w 0
KEY_SKILL2 = SDLK_z SDLK_i 0

KEY_QUIT = SDLK_ESCAPE SDLK_q 3
KEY_PAUSE = SDLK_p 0 0
KEY_CONSOLE = SDLK_BACKSLASH 0 0
KEY_TILT = SDLK_t 0 0
END
I ask you experts for a way to fix this problem that is stressing me out because it doesn't allow me to play my favorite games. Thank you all and sorry if I steal some of your time.

DirtBagXon

@22marco77

If left and right are switched, just change the + and - signs on these two axis arguments:

From:

KEY_LEFT = SDLK_LEFT SDLK_d 8 -1
KEY_RIGHT = SDLK_RIGHT SDLK_g 6 1

To:

KEY_LEFT = SDLK_LEFT SDLK_d 8 +001
KEY_RIGHT = SDLK_RIGHT SDLK_g 6 -001

I use 001 but you could just use 1 as it's the first joystick axis.
