RELEASE Chiaki (PS5 & PS4 remote play) homebrew

Some (very rare?) PS4 games also has different behavior based on where you press the touchpad button (each corner can be assigned to a different button event), while some game only has left side and right side differences.
4 buttons touchpad (corners) : Killzone: Shadow Fall
2 buttons touchpad (left/right) : Diablo 3, Star Ocean: Till The End Of Time,
1 button : most games!
of course some games also use the swipe/touch without pressing/movement effect (Dreams, Detroid, Risk of rain, etc. )

If you implement touchscreen, I suppose the "touch sensitive" without press could be the center of the switch screen, while each corner could be the button event with "touch" corner coordinate sent to the game?

edit:
I found this, here : http://gimx.fr/forum/viewtopic.php?t=2741


showing it can detect 2 fingers, at different corners at the same time.
x- (left side), x+ (right side).
that picture's HID config seems to only have 2 sides triggers, not 4 corners triggers.

 

Can you do key combinations? For example, minus = touch press, hold R1 + minus = PS button?

 

holding R1 could do other things in the game you wouldn't want. event if it's holding minus first, it could be difficult to access quickly ingame.
If you can detect touch zone on the switch, it could act as buttons (4 touchpad button event actually).
the NDS and 3DS had lot of games using virtual buttons located on the touch screen to expand the available inputs.


The touch also detect if there are 1 or 2 fingers on the touchpad. (I don't know any game using two fingers, probably pinch and zoom out? if someone knows one it would be nice to help debug/test)
Assigning only one physical trigger (R1+minus) without touch info will not be working in all games.

 

From a quick look at the main chiaki repository source & issues, it doesn't look like chiaki supports detailed touchpad support in terms of touch location, swipes etc, so far - it just supports it as a plain button. This will work for a lot of games but obviously there's a few games that it's not gonna be able to support until that stuff is added.

I just sent you a pull request for touchscreen-as-touchpad-button support, works with The Last Of Us at least

 

You're very welcome, thanks for the quick merge & release!

Really appreciate this app, it's what I've been waiting for for ages. With overclock it seems really smooth & playable (haven't tried it for very long yet, but it's looking ready for more extensive gameplay tests). And now I can play TLOU, which is my priority, replaying to refresh myself before the sequel comes out

 

BTW it would still be very feasible to use multiple zones on the Switch's touchscreen, so as well as emulating the touchpad button, you could have an area for the share button, and one to quit the app (or open the app's menu, once it has one). Not my priority, but I could look at it sometime if it was wanted.

Speaking of quitting the app, I thought maybe if it can detect when the stream ends (PS4 goes to sleep or turns off, or connection lost maybe), the app could quit.

 

It's possible to add the wake up/turn on functions?

 

Yeah, i try the remote play with lineageos-switch and wake up works.

Thanks

 

what is the minimum overclock you can do to get rid of the graphical glitches?

 

Many thanks for this homebrew.

I struggled a bit in the beginning and had both crash and green screen on different occasions.

When the keyboard popped up I didn't realise that I had the put the pin code to add the device.
Once I passed that stage and the app successfully connect to the PS4. I quit then relaunch the app.
It crashed.
I looked at the config and then

removed the [PS4-XXX]
From the config file and I just have replaced it with my ps4 name [myps4name] in the config.

So there's was only one [PS4-xxx] config.

Would it be possible that you had the same issue @hippy dave ?

It works well at 720p but the is a noticable audio lag.
I have been playing persona 5 on 540p and so far it's working great.

I'm amazed that the hombrew works fine when launching from the album icon in switch but now that i have fixed the green screen / crash issue, i use the title redirect.

 

I made a forwarder, just so I can have overclock set for this app every time without affecting other homebrew. Forwarders can apparently cause issues in some cases (eg I know there are potential problems with retroarch), so try at your own risk. If you have any issues while using it, see if you get them without using the forwarder before reporting.

e: it runs /switch/chiaki/chiaki.nro

 

Thank you, runs perfectly. I played 1 hour to FFVIIR and no problem.

 

emuMMC | HOS 9.2.0 | AMS 0.12.0
proper chiaki.config (checked many times)
switch crashes any time I start chiaki.
crash happens in bsdsockets-sysmodule

Spoiler: my config

Code:

[PS4-AD2076]
host_ip = "192.168.178.22"
psn_online_id = "daigo_"
psn_account_id = "**********"
video_fps = 30
video_resolution = "720p"

 

No logs
I am not running from applet mode. In applet mode it fails on titleID 010000000000100D
Should I update HOS?

 

Shouldn't you either remove the line with psn_online_id or
psn_account_id

Depending on you ps4 firmware?
