Thank you I will try these suggestions.

Hello,

for me (PI 3 with retropie 3.6) it's :
axis_trigger_left = 2
axis_trigger_right = 5

and

[compat]
btn_trigger_left = 312
btn_trigger_right = 313
axis_dpad1_x = 16
axis_dpad1_y = 17
axis_dpad2_x =
axis_dpad2_y =
axis_x_inverted = no
axis_y_inverted = no
axis_trigger_left_inverted = no
axis_trigger_right_inverted = no
axis_dpad1_y_inverted = yes
axis_dpad1_x_inverted = no

And you can use :
btn_escape = 316 (Xbox button) to exit game.

Have fun!

Hi, thanks @BuZz - all seems to work now. I got a few errors flash past as it was building but nothing that has stopped it from working. Hope it fixes it for you too @simonster.

I did have to play about with the retroarch.cfg file in the /nes folder to get it to work with my NES controller, but fixed it by setting the player 1 control to:
b_btn = "1"
select_btn = "2"
start_btn = "3"
up_axis = "-1"
down_axis = "+1"
left_axis = "-0"
right_axis = "+0"
a_btn = "0"

All the rest to "nul". If I didn't do this then as soon as I started a nes game it would not respond - I'm sure there is a proper config, but I spent a few hours playing about with the config files before I got it working so now enjoying some sweet retro gaming :)

Did you by any chance install the raspberrypi-sys-mods package as described in this post, fourth paragraph down.

I am using berryboot. That would make sense then. Thank you. I'll try a fresh image only.

and fixed ;-)

fba version works just fine, great advice thanks. I do love the Dreamcast graphics but moving over to fba saved me 700+mb.

Thanks, I'll give that a try.

Oh exactly what I needed! Thanks a lot :D

Generally you do not want to mess with the permissions of such system files :)
Just modify them with sudo or on a computer, its safer overall.

Nice another OCD person, Its took me a week to put my games on because im so fussy about presentation etc...and picking the splash screen took a while...

Thanks, worked like a charm!

I'm no expert in this (so disclaimer over) but could it be setup to happen automatically using the idle settings?

@heroshade644

What method did you use to migrate your roms to the thumb drive?

thank you for the advice, I really appreciate it

After some consideration, I think I might leave emulating the PSX, N64, Dreamcast and Saturn on the Pi, alone as I have another project in mind to do those one that wont require the Pi. At this point I just wanna make a emulation console that can play the classic stuff (NES, SNES, SMS, SMD, ect, ect) So with that being said, will that still require a heatsink?

Asking because I wanna know what I need to buy so I can do it all at once >.>
