Warmtoe has released another version of lgtest in the hopes of getting more of the non-working light guns running with Nester 7.1+b, you can download it from this link. Here are some of the details about it from this forum post:

“I think I may have found a reason that some guns are not getting recognised, KOS calls the DEVINFO command but perhaps some don’t respond to that and need ALLINFO – which returns everything that DEVINFO does and some more – the MadCatz guns return the same info in both cases – so I can see, that it’s possible, some guns don’t return anything for DEVINFO, only ALLINFO – it’s all theory as I don’t have a failing gun.

The above version dumps a tonne of stuff to screen and out to the console – can you give me all the information on screen (or as much as you can bare) – specifically on any guns it didn’t recognise before but does now or ones it still doesn’t recognise!“
