@rasp_renegade Hello, it happened to me too. But after loading a new firmware ( IPAC2_155c.ufw ) under the WinIPAC, I also loaded the Default Ipac2.ipc ( you can find it under C:\Program Files (x86)\WinIPAC V2\Defaults\ folder. Somehow before this there was no keys are mapped. The default Ipac2.ipc solving such a problem easily.
Finally got it to work!!! For those with a similar issue. I deleted the retroarch config files, then cleared the controllers via emulation station. next I reinstalled Retroarch, and rebooted, meaning Emulation station allowed me to remap the controllers.
Despite ES showing my controllers and assigning them to the Retroarch_joypads folder as DragonRise Generic USB, Retroarch had it as DragonRise N64.
So I just copied the file from udev folder, into the Retroarch_joypads folder, and deleted the other one.
Next I went into Retroarch itself via the setup menu, and selected the Control tab in Setting. The new version gives some nice new options, such as Quit Retroarch combo (I think) and Toggle menu, which I set to "Hold Start for 2 seconds".
There is also a menu option further down the list that i set to a spare button just in case.
I then copied the retroarch config file from the all folder into the arcade folder, replacing the one in there.
I then launched pacman, held down Start for 2 seconds, with great relief I got up the menu, carried out what @lostless said, and it works a treat!!
Now on to the next load of 4-way games!!
I'm not working with the best screen and, with black on gray, that's just looked - well it was unclear to me. 2 years ago I'd have probably remembered it, from the other system I've mentioned, but on the screen I'm using now (usually devoted to something else), it's hard to see. (I have to change terminal settings on most of my systems to use something like green on black that look like the old phosphor monitors so there's good contrast.)
Okay, I'll use that later today when I'm at over where I have that system.
(This is a temporary environment for it - I'm setting it up to send to a relative who has just moved out of his house, so this is something for him to do when he's stuck in his apartment at night, alone, without a wife or kids anymore. He has some game consoles, but has never had anything like RetroPie.)
Just wondering - is there a reason that notification is in something lower contrast like black on gray instead of something like red or green for the text? (I realize it's on a black screen, so you can't use black as a background.)
@sleve_mcdichael then there's the problem right there lol. Thank you for all your help, you've spent a lot of time on me. I'm going to continue to read up on this. It's all a learning experience for me and very interesting. Happy new year to you!!
if your dolphinbar isnt recognized as a mouse+kb then its in the wrong mode. i believe the correct mode is #2
[EDIT sorry i read your question wrong.
I think the easiest way to achieve what you want, is to just go into the retroarch menu after you launched the game, back out to the main menu, select "input" and bind your button there.
I've always had my coin and start buttons bound to a separate controller while using the Wii mote as a lightgun.
I tried multiple solutions suggested here, but to no luck. In the end, I just started the whole installation all over again and it's working fine now. God knows what happened, but it seems re-installing everything seems to have fixed it... weird.
