V35 X86_64 Model 3 Star Wars Trilogy Bizarre Light Gun Issues.

DDaz

Hi Guys. New to the forum and relatively new to Batocera. With the help of YT videos (Batocera Nation and the like) and forums like this, my build has gone extremely well with most machines working as they should. However, I have an issue with the Model 3 Star Wars Trilogy and the use of a Wii lightgun that is causing me to pull my hair out!

I see from other users on earlier builds that Wii lightguns can be used with the Mayflash Dolphin bar and said ROM easily enough. My issue is that I can load the ROM(s) (swtrilgy & swtrilgya) just fine but with each ROM I can only move my lightgun in one axis, either up/down (on one ROM) or left/right (on the other)! I’ve tried using the ROM calibration screen but again can’t even move in one of the axis to calibrate it. Note: On one occassion (just one, out of the dozens I’ve tried!) both axis did actually start to work but after exiting the calibration screen and rebooting I could no longer play the game as once again only one axis worked. Both axis on both ROMs always work fine with the xbox controller. I have tried a couple of different versions of the ROM as well to no avail.

I assumed the issue was with my Mayflash Dolphin bar or Wii controller despite them working with other Model 3 lightgun games just fine (LA Machine Guns etc.) but after swapping to another Wii remote and using a standard Bluetooth connection and bar I got exactly the same result!

I really have no idea what is going on.

I notice in V35 there is no gunmark icon next to the Star Wars ROM so am wondering if there is there an issue with V35, lightguns and this ROM or am I simply doing something wrong?

Assuming others have it working, the only other thing I could think of doing was deleting the .nv file in case of a corruption but that seems to be locked-down pretty tight even when using WINSCP. Again though, I’m new to all this so could be doing something wrong.

Anyway sorry for the lengthy post but any help you could suggest would really be appreciated.

Try the precalibration nvram : https://github.com/batocera-linux/lightguns-games-precalibrations/tree/master/saves/supermodel/NVRAM

It should be saved in /saves/supermodel/NVRAM folder

I suspect your NVRAM to be corrupted or at fault. This ROM is currently a bit tricky to make it work with “mouse”. It’s not working by default, but was fixed for all light guns in beta 36. Make sure you do what the latest ROMset because supermodel is now using latest versions with all its updates from previous ROMsets versions.

Great, thanks for that @tovarichtch . I was guessing something was amiss with the NVRAM and had previously tried to delete it without success even whilst using WinSCP. I’ve successfully downloaded the .nv files mentioned but am again having difficulty replacing the existing ones with the error message saying they are read-only even though I have again tried via WinSCP with user: root, password: linux. I’m new to using WinSCP so maybe there’s something I’m not quite doing correctly? Also, just to clarify though, are you saying it won’t work at all with v35 only v36beta?

tovarichtch

DDaz v35 won’t trigger the light guns setup for that game. If you want to use light guns in v35 for that ROM, you need to add the following line in /userdata/system/batocera.conf at the very end :

model3["swtrilgy.zip"].use_guns=1

Then in terminal (f1->applications->xterm) type :

batocera-save-overlay

It should work.

This is fixed in v36 (currently in beta)

DDaz

Thanks for your patience & suggestions @tovarichtch . I edited, saved, rebooted & re-checked the .conf entry with the change all presnt and correct. However, as soon as I started swtrilgy again I was back to experiencing the lightgun movement in the Y-axis only with no recognition of the x-axis. I went further and did the same for swtrilgya (on the off-chance) and that one would only work in the x-axis!!! I also redownloading the roms in case I was accidentally using outdated ones. Alas, it was still not working so I’m back on your assumption of replacing the .nv file. However, as mentioned previously, that is also causing a problem in itself. Using WinSCP or PuTTY to try and delete the swtrilgy.nvI file is failing because of it being a ‘read-only file system’. I am using the command rm -f swtrilgy.nv from within the /NVRAM folder. This is all so very frustrating.

tovarichtch

I’m 100% it’s your NVRAM.

Can you at least connect to your SHARE network by typing \\BATOCERA in the window explorer address bar? This should show your SHARE partition. For WinSCP, it’s important to connect as root/linux to have permission to modify/add/delete your files. Otherwise, do it within the file manager of Batocera (F1).

Note that this game was tested with all compatible light guns, excluding Mayflash Dolphinbar + Wiimote.

DDaz

@tovarichtch Success!!!

Initially the replacement of the NVRAM file didn’t work (managed to delete & replace via F1 direct edit) , so out of shear frustration I installed a new version of Batocera on an old laptop, replaced the NVRAM file, amended the .conf file, put on a random version of swtrilgy and connected the Mayflash bar…and it worked! Bolstered by this success I went back to my original installation (Dell Optiplex i5) and deliberately replaced the now known good NVRAM & swtrilgy files used on the laptop, re-did the .conf file, started the ROM and…still only movement in one axis! Arrggghh!!! The only logical difference I could see between the two PCs was the working one used my old Mayflash bar and the new the standard IR bluetooth connection. That must be it I thought! So I connected the Mayflash bar to the Dell…and again failure! I was spent at this point and really couldn’t understand this completely illogical scenario. In a last act of desperation, and I’m not sure why, I then tried swapping the Xbox controllers over…and it worked…on both Mayflash & IR bars or even both together! I have absolutely no idea why the original Xbox controller was causing issues especially when other Model 3 lightgun games worked, but importantly the replacement wasn’t so I’m one happy bunny!

Thank you so very much for your help and patience with this, I wouldn’t have got there without you. Kudos!

Follow-Up:

So it worked until the next reboot then stopped working again. With a bit of experimentationI realised it seems to be a conflict between the lightgun and the left-analog joystick on (any) Xbox contoller that’s plugged-in at the same time. Ocassionally it works, 95% of the time it doesn’t. I say this as by wiggling the the joystick whilst moving the gun sometimes causes the gun to work for a while! However, until somebody can explain why this is I have discovered by simply booting batocera with just keyboard & Lightgun (no xbox contoller plugged-in) swtrilgy works correctly every time!

Are they officials or clones Xbox controllers? That’s what I have (xbox wireless controller, model 1914) and I do not have this problem here. I’m connected directly to Batocera, on my machine with its own chipset (no dongle). Try upgrading your firmware on your controller?

DDaz

Hi @tovarichtch . They are the official WIRED USB Xbox 360/PC controllers. Can’t see any updates for them on the web but that makes sense as I assume the firmware updates are to do with the wireless element of the controller? My BT controller for the Wiimote is a dongle (Batocera supported one) though I don’t think that is the issue as the Mayflash is the same. Very strange that yours works fine though. Doubly strange that the other Model3 lightgun games work well. I think my son may have some old wireless Xbox controllers somewhere. I’ll hunt them down and see if that makes any difference. Cheers.

DDaz

Hi @tovarichtch you’ve steered me in the right direction again! Couldn’t find any old 360 controllers but borrowed some wireless PS4 ones from my son. They allow Star Wars to work perfectly with the Lightgun! So after all of that it would appear that the issue was with some weird conflict between the old wired USB Xbox controllers and the Lightgun bar when plugged in together…but just on that game. Weird.

tovarichtch

I believe the problem is the Mayflash Dolphinbar itself. I have that controller too here (xbox 360 wired). I will try this weekend to see if I can reproduce your problem on my part with the Mayflash Dolphinbar default mode (I have this here). But since v35, we strongly discourage the usage of Mayflash Dolphinbar as your Bluetooth device for light gun gaming with your wiimote. You can read about it in the official wiki guide: https://wiki.batocera.org/emulators:lightgun_games

If you are interested to try this new feature of Batocera with your current Mayflash Dolphinbar, let me know. There’s a quick fix to make it work just like a regular sensor bar (I need to update the wiki page soon). You’ll just have to connect to any compatible Bluetooth dongle/chipset with the LEDs on.

Edit: it’s possible that the ROM itself is problematic too (old ROMset). I will report back.

DDaz

@tovarichtch Thanks. It will be interesting to find out. I have 2 x wired Xbox controllers, the Mayflash bar and a standard IR bar for use with my wiimotes. All are problematic together not just the Mayflash. All work with the PS4 Controller. MAybe it is the ROM as I mentioned earler the other Model3 gun games seem to work fine with the Xbox contollers + Mayflash or IR bar.

tovarichtch

DDaz So, I’ve tested with :

1 xbox 360 controller + Wiimote connected to Mayflash Dolphinbar = stuck to X axis

1 xbox 360 controller + Wiimote connected to Batocera directly = stuck to X axis

1 xbox 360 controller + gun4ir = stuck to X axis

1 xbox series x controller + gun4ir or Wiimote = all good.

Yeah, that controller doesn’t like light guns I guess on this game. This is an issue, no idea how to fix this atm.

@DDaz

Not sure if you read the information on the Batocera Wiki, but it said SWT, for Model 3, needed an in-game calibration, and that it works on Romset 0.245. Are you possibly using a different romset? Also, avoid upgrading to v36, as the wiki shows that there is no gun support in v36. Also, just reread the thread and noticed @tovarichtch touched on the rom issue

Model 3 Lightgun Support

Emulator Lightgun Support Sheet

Hope this info helps!

tovarichtch

Sorthious Oh crap, that’s my mistake! There is light gun support on v36. I’m fixing that right now!!!
