[BUG]: USB - GunCon 2's calibration shots not always work as intended

[IlDucci]

Describe the Bug

I have tested some PAL GunCon 2 games and found out that the Calibration Shot does not work sometimes as it should:

• Vampire Night PAL (SCES-50411) is not working at all. I'm not being capable of calibrating the gun, not with the Calibration Shot, not with the normal Trigger.
• Dino Stalker PAL ENG (SLES-50930) always recognises the first Calibration Shot as a double press, making the game recognise only the horizontal movement. Pressing A/B and then recalibrating will make the process work correctly.

Reproduction Steps

• Go to the calibration screen of each game.
• Try to calibrate the GunCon 2.

Expected Behavior

• Vampire Night should let itself be calibrated. This is a major bug for this game.
• Dino Stalker should have no surprises on a first calibration pass. This bug can be workarounded by doing a second calibration.

I can confirm this - you cannot bypass the cali screen on Vampire Night because of this.

Time Crisis Crisis Zone also suffers from the same issue, except 1 out of every 20-30 shots I can get it to work on cali screen in that title, never on Vampire Night.

Fwiw, both of these games previously required nuvee plugin's setting "mouse calibration hack" and work perfectly with it on:

Related, this can be closed now - it was locked and I can't do it: https://github.com/PCSX2/pcsx2/issues/3931

Time Crisis Crisis Zone

I was able to properly calibrate and take the proper measures from the PAL version with no problem.

[Comfarol]

try this for pal vampire night

You need to find the correct values

[IlDucci]

try this for pal vampire night

Welp, those values actually unblock the calibration screen issue. The scale seems to be a teeny bit off when the cursor is close to the top and bottom, but at least the game works.

[Comfarol]

I can't test alot of the other games as I don't own them but try, see if those are better, looks better for me.

89.80 99.90 421.00 138.00 640px 256px

[legend800]

Those work fine for Vampire Night, along with the below set posted in the other thread: 90.25, 102.75, 422.50, 137.00, 638px, 228px

Neither seem perfect as I need to shoot a few times in the target area on cali screen to get it to register. But once calibrated and in-game, seems perfect. Nice work!

Seems like the default/auto values are fine for NTSC but not many PAL games.

[dante3732]

This works well for vampire night usa. But as wrote above, you need to take several shots to calibrate. Game have 640x228 resolution.

I also tried to calibrate the code veronica gun survivor, but I failed.

[Comfarol]

Vampire Night USA is 640x448

Are you using the calibration button you bound in the settings, it calibrates every shot for me.

I used yours but fine tuned it on my end and using

89.80 105.10 422 124 640 224

These values any good for you, does it improve your calibration issue?

The default values pcsx2 is using prob bad

[dante3732]

Vampire Night USA is 640x448

Yep, you right.

These values any good for you, does it improve your calibration issue?

Yep, you value fine, but my value little better for me. My value just points to the center of the circle in each corner, and yours shifts a little, but it not critical.

[Comfarol]

Someone will have to update it with the above values then, by default its loading those cooked values

[IlDucci]

Someone will have to update it with the above values then,

I can do that and add the other values I figured out. The thread is still valid until the issue with Dino Stalker is fixed.

Dino Stalker PAL? USA work fine for me.

[IlDucci]

Dino Stalker PAL?

PAL, yes. See the first message.

[Comfarol]

Dino Stalker PAL has no default values

[dante3732]

I tested 11 games. Time Crisis jap OK Time Crisis 2 usa OK Time Crisis 3 usa OK Crisis Zone usa OK, (If after calibration, the rifle can only fire single shots, in which case you need to repeat the calibration again until the rifle starts shooting properly.) Dino Stalker usa OK Resident Evil Dead usa OK Gunfighter II europe OK Endgame usa OK, but need plug guncon in usb 2

Virtua Cop pal BAD calibration work good, but there is a very long delay before the shot is fired Vampire Night usa BAD can't calibrate on default pcsx2 value (It fixed by custom) Resident Evil Gun Survivor 2 pal BAD the mouse cursor does not match the sight in calibration

[Comfarol]

Have you tried VC since update? It had bad values.

[dante3732]

Have you tried VC since update? It had bad values.

Yep, i tested again now. Calibration good, but fire input lag too big, approximately 2 seconds.

[Comfarol]

I'm not getting any lag when firing on my end.

[dante3732]

I'm not getting any lag when firing on my end.

After recalibrating in the main menu, there was no longer such a delay. Apparently there is still some kind of calibration problem.

[IlDucci]

I just realized that Dead Aim's settings were targeted to the PAL version, not the NTSC-U one. Anybody has Dead Aim on NTSC-U?

[dante3732]

Yep, USA work fine for me, but i use no interlacing patch.

[IlDucci]

Please test it with the values that I just uploaded here: https://github.com/PCSX2/pcsx2/pull/7636/files . And also make sure you have no patches enabled.

[Comfarol]

You doing Vampire Night USA values from above too?

[IlDucci]

Nope, those were the ones from before. I wasn't sure which one of the two sets were the final ones. Can you tell me?

[Comfarol]

89.80 105.10 422 124 640 224

[Comfarol]

The other games you guys are talking about i don't own so i cant help you there

[IlDucci]

My value just points to the center of the circle in each corner, and yours shifts a little, but it not critical.

What about that?

[Comfarol]

I dunno its perfect to me. he seems to be having issues so im biased :D Either is fine you talking a few pixels

[dante3732]

Looks fine.

[IlDucci]

Try this (and let's hope GitHub doesn't pose any trouble): do a little video recording of the game on the calibration screen, with the mouse cursor being seen (OBS Studio should be best for this), after doing the calibration, but before leaving the calibration screen. Simply move the cursor to the center of the screen and then to the four corners, as close as you can to the screen limits.

[Comfarol]

its like two pixels between his/mine. im not making a video sorry, use his

[IlDucci]

Done.

[Comfarol]

Dino Stalker PAL works with values, its a little bit off on the edges if you want to fine tune. The FMV is so bad tho holy xD

[dante3732]

The FMV is so bad tho holy xD

Just enable autosoftware for FMV.

Gun Survivor 2 Code Veronica PAL, I spent a lot of time and could not choose more precisely, you need to calibrate by trigger button.

[dante3732]

I captured input lag in veronica and virtua cop. The trigger is pulled when the screen flashes. And the shot happens in 2 seconds. This happens in 2 of the 11 tested games. https://drive.google.com/file/d/1XWx50MKMA3WV3JXPaPknlxMXqnXAs6wv/view?usp=share_link https://drive.google.com/file/d/1vp2YtPC-j-VLjiLXy401bPYW-gAeNjN-/view?usp=share_link

[refractionpcsx2]

I don't think that's input lag, the input triggers the white screen, not the visual shot, the game does that. The white screen is a result of you pulling the trigger and the game flashing a white screen to find out where on the screen your "gun" is pointing, it then decides where you shot and does the shot effect.

[legend800]

I only get the long black screen if I go way out the circle on cali (with default values). So there's still something funky here but it's not really impacting. I see you can get a lot of shots off fine when on the target.

Are you sure you calibration is saving? As I mentioned in the other thread, the steps are convoluted, but it works perfect for me if I do them.

Press Start, fire in center, fire offscreen, select Ok, with Press Start up, fire offscreen again. If you do that, you'll get this: Select Yes and go in-game

[dante3732]

Press Start, fire in center, fire offscreen, select Ok, with Press Start up, fire offscreen again. If you do that, you'll get this:

Yep, i make same.

Don't press start. It seems if you press start then try calibrate you get the black screens and delays. If you just Calibrate and shoot off screen and pick yes its fine.

[legend800]

If you don't press start, you're not calibrating. No matter where you shoot, the gun cursor does not change until you press Start. All your doing is bypassing it with those steps, which maybe fine for your setup. Maybe the cali screen is throwing things off for you. For me, it just breaks gameplay. I confirmed this by going in game and sure enough it's off-center like it was on cali screen here.

Please double check your iso is not patched, reg/ws cheats are disabled, check video/input settings, etc.. I had a similar issue on TC4 with missing gunshots on rpcs3 and it was only fixed by set fps cap to 30.

[Comfarol]

Mine isn't modded and I have no cheats. Only graphics setting i have is high blending and anti blur. Maybe yours is modded and has cheats?

When i start the game the cross hair is perfectly positioned with out calibrating, maybe that's why. What if you use custom settings to adjust it into position and not press start like what i do.

[legend800]

I'm sure that'll work too. If the "auto" defaults line up my gun cursor with mouse cursor, then yeah, I can just skip all this stuff. That's ideal. But until the default does that, it's easier for me to go through the full cali steps vs. changing custom calibration settings, since I'm already using current values for Vampire Night. :)

[Comfarol]

Why do you need settings for Vampire Night, do the defaults also not work for you on that game too?

[legend800]

Yeah, there was a bunch of conversation on this in the middle of the thread above. And only works with custom settings right now, until a new PR is cut.

[Comfarol]

Pretty sure its out? Mines working now with no custom settings.

[Comfarol]

Anyway with VC it seems the default values give different results for others for some reason? A per game GunCon 2 custom setting option would be the ideal way to get it accurate for individuals (and other games) until what ever is scuffing the calibration screen is found/fixed. It is scuffing because the JPN version calibrates with the same black screen with no prolonged blackness and delayed shooting.

[legend800]

Pretty sure its out? Mines working now with no custom settings.

Ah, nice. Yep, Vampire Night (usa) is fixed now using automatic/default settings on the latest nightly.

[dante3732]

Need replace value in Gunvari Collection + Time Crisis. This is a collection of games, it uses one calibration for menus, and the second for games. The current values are only suitable for the menu, but accurate calibration is not important there. So if you can't use 2 values one for games and second for the menu, then replace the current one on mine. 90,25 91 390,50 138,50 640 240

I figured out Virtua Cop, if the screen turns black after the shot and does not return to normal, then you need to repeat the calibration until it flashes once, then everything will work fine.

I also figured out the Time Crisis Crisis Zone, you need to press the calibration button until the screen stops flashing black (it flashes exactly the first time you press the calibration button, but stops after a couple of press), then the riffle will fire bursts without problems.

There was only a problem with Gun Survivor Code Veronica that I could not solve.

[shanethmoore]

I've noticed a lot of comments saying that Time Crisis 2 and 3 are perfect but I'm not so sure thats true. For single player calibration and gameplay it works fine but with split screen the calibration seems to be ignored and instead the cursor shots shows float outwards on the X and Y axis from p1 center screen or p2 center screen.

Unsure if it's calibration related or something else entirely. Could be worth mentioning here or https://github.com/PCSX2/pcsx2/issues/7619

I'd wager https://github.com/Comfarol/pcsx2/blob/e018c1ac06ed49fb3cc68be66f3f55f4ec67ce65/pcsx2/USB/usb-lightgun/guncon2.cpp#L79 needs to be updated based on whether the game is single or multi player.

[legend800]

Good point. 2p was mentioned in the original PR that it would be added/supported in a feature commit.

FWIW, here's the values I used in nuvee plugin for either SP or MP for reference:

;time_crisis2 "Time Crisis 2 (U) - 2p" 95 45 390 150 namco 640 240

;time_crisis2 "Time Crisis 2 (U) - 1p" 120 97.5 390 154 namco 640 240

;time_crisis3 "Time Crisis 3 (U) - 2p" 95 45 390 150 namco 640 240
