Hello there. I'm a bit of a noob, but managed to follow Launchbox tutorial on adding Intellivision games into Launchbox using using freeintv core in Retroarch. Games open fine but I have little to no control with either my xbox 360 controller or my arcade joystick/buttons, and no option for remapping buttons. So I want to swap to Mame as I'm more comfortable mapping the keys with it, but have not managed yet. I think I'm getting a bit confused with folder structure and where to put the bioses required.
Currently have intellivision games in int. format in folder named Mattel Intellivision, with bioses zipped in same folder. I also tried creating Intv folder in Mame folder with bioses in that, no good.
So, what am I doing wrong? Do they need to be in different format? Do I maybe just add roms to Mame rom folder?
FYI, my mame set is non merged 0.243 that I curated using All killer no filler bat file found on here, and it's working fine.
Any and all help much appreciated 😊
