Having issues with some platforms not launching in Big Box mode (loading..then back to game select)

[Braaaindog]

So my SNES, Jaguar, Dreamcast, N64 games work amazing. I dl roms from a set from the Internet Archive. I don't know what I'm doing wrong with PSX, Colecovision, Intellivision games. I'll hit play on the game I want in Big Box mode it will have my loading screen and then it just goes back to the game in Big Box.

I'm using Retroarch for most games and I have the cores downloaded. 

I'm not very knowledgeable about a lot of this (YouTube has been my friend) but some things I've noticed are: the PlayStation games I've downloaded are extracted into the sony PlayStation games folder within lunchbox folder and those ones are either .cue? Or .PB(PB?), or .iso files and that's different from some of the other file types I've extracted before.

I also use Retroarch for psx but when I launch a game it said swanstation libetro or something of that nature but the PlayStation core I only have downloaded is the epsxe one.

I use no other emulators except Retroarch and the PS2 one is a different emulator. I've made sure that I have cores downloaded for each platform, the only extra command I have is -f to launch game in fullscreens automatically. 

 

Any help is appreciated and I will provide screenshots and other details if necessary
