Light Gun!!!

mediamogul

how i enable a "gun" addon to be turned on in nestopia i have no idea.

It's probably just not an option. I really wasn't sure.

Edit:

No, I never bothered, but I can do a test if that helps.

There's no need I really. I'll be playing around with this a lot this evening.

Thanks for finding this @a7mag3ddon and thanks again @dankcushions for your excellent work in enabling the support to begin with.

@a7mag3ddon it is supposed to just work with the NstDatabase.xml file in the /opt/retropie/libretrocores/lr-nestopia which it is in retropie but it doesnt do anything. I have the nes shooting roms and the playchoice 10 and the vs. system ones and i cant get any of them to recognize even a mouse click let alone the movements.

mame2003 for sure will only read mouse0 only. retroarch only understands one mouse device. i'm not sure what could be going on.

Hmmm. Well, I just double checked. I can do a cat /dev/input/mice and see input when I play with my spinners and when I touch the trackball. Then, I can do a cat /dev/input/mouse0 and only the spinners cause input. Then I do a cat /dev/input/mouse1 and only my trackball inputs are displaying.

Then, back into ES, and I launch Blasteriods with lr-mame2003. 2-player game (XY sharing enabled) and I can move both ships, one with each spinner and with the two directions on my trackball.

Trying Centipede and I can move with the trackball and with the spinners (like an etch-a-sketch).

I am delighted with how it works, but I have to conclude by this that lr-mame2003 on my system is taking mouse inputs from the "mice" device and not simply mouse0.

@caver01 that makes sense. the retroarch Linux mouse driver must just return any mouse input as coming from a single mouse device. so it's picking up mouse0 and 1 but since it presents them to the core as a single device, it can't separate them out for p1 and 2 (other than through hacks like my spinner fix).

or something like that. not worth investigating IMO as retroarch needs to handle it better in any case.

Agreed. Anything more than the capabilities you have enabled would require a complex method of assignment similar to what you can do with AdvanceMAME. I can imagine core options that could be set in per ROM configs, but they would have to be carefully designed so as to cover the many possible combinations that might come up across all of the ROMs supported and hardware possibilities. It could be a big mess, even if retroarch could see more than one aggregate mouse.

I'd just like to chime in and confirm that I recently bought two Aimtrak guns connected to my RetroPie arcade cabinet setup. They both work well with advancemame. My overclocked pi 3 runs Area51 full speed along with most lightgun games that came out before it.

Both Aimtraks automatically worked after I unplugged my trackball. The only irritating aspect of the setup is that calibration is just about impossible using retropie, so I'm left plugging in a windows laptop to do a generic calibration (which is saved in the guns). The problem with that is different games have different resolutions and aspect ratios, which alters the calibration. It's no deal breaker, as the cursor can always be on-screen allowing you to accurately shoot whatever you want. This is perfectly fine (and is a lot of fun) playing in a "shoot from the hip," style; but if you like to play by looking through the sights, the aim will be off.

I haven't been able to get any of the other systems to work. While I would love to be able to play some of the ps1 lightgun games, I feel the purchase was more than worthwhile. A huge part of arcade gaming back in the day involved lightgun games, so being able to enjoy the experience blasting away on Area 51, Lethal Enforcers, Point Blank, Operation Wolf, Hogan's Alley, and Duckhunt fills a huge hole in my retrogaming heart.

Reeaally... What are your overclock settings, if you don't mind me asking?

@ajhorst Cool, can you help with a little guide for all of us, who also would love to play theese lightgun games on retropie?

I managed to build a bartop arcade with the help of guides, even though I don't know anything about programming, wiring etc - but I haven't seen any guides on this. And I think a lot of people would love to be able to play these games!

Pretty please! :-)

ETA Prime's YouTube Video on this is an essential. It works great.

Howdy, saw this post and i was interested in building an area 51 cabinet. Wondering what pc and program version you used, and where you got the software versions for the game? also, how did you configure the light guns to work with the lightbar? I assume you used a 1 up arcade correct?

This post has originated almost 4 years ago, I doubt this was a thing back then.
