Issues configuring RetroArch for my handheld

[No Hands 55]

A couple issues I need help with, would really appreciate any advice! Cant setup saving and cant get fullscreen fit.

• I cannot get a button or button combo to work for save states. I uncommented the savestate in retroarch.cfg and tried "r" or does it need to be just r? I have the r key mapped to my handhelds L2 button. Do i need to put L2? Tried Select + Down or does it need to be the keyboard keys like LEFTALT + DOWN? Does it need quotes? I feel like ive tried all combos and am not sure if its formatting or im setting it wrong.

• I am running composite on an 3.5" from adafruit. The splash screen and games do not fill the screen, emulation station does. I enabled overscan=1 and it filled the whole screen, but it went to far and cut it off. I have fullscreen enabled but it doesnt change anything. Any advice?

Thanks!

I have an Xbox 360 controller that I use but I believe it will work for the SNES controller as well. Here is my configuration:

$ sudo nano /opt/retropie/configs/all/retroarch.cfg

# Alternatively, all hotkeys for keyboard could be disabled by the user.
# input_enable_hotkey_btn =

# Hotkey button
input_enable_hotkey_btn = 8 #Select
# Exit emulator
input_exit_emulator_btn = 9 #Start
# Saves state
input_save_state_btn = 1 #B button
# Loads state
input_load_state_btn = 2 #X button
# Move to next save state slot
input_state_slot_increase_btn = 5 #R button
input_state_slot_increase_axis = +0 #Right on D pad/Left Stick
# Move back a save state slot
input_state_slot_decrease_btn = 4 #L button
input_state_slot_decrease_axis = -0 #Left on D pad/Left Stick
# Reset ROM
input_reset_btn = 0 #A button
input_reset_axis = -1 #Up on D pad/Left Stick
# Toggle RetroArch menu
input_menu_toggle_btn = 3 #Y button
# Volume controls: mute, volume up and down
input_audio_mute_axis = +1 #Down on D pad/Left Stick
input_volume_up_axis = -3 #Up on Right Stick
input_volume_down_axis = +3 #Down  on Right Stick

Thanks! So you don't have any of the number in quotes i see. I wonder if that is different when it is keys?

I have tried things like input_save_state = "Q" and it still is not seeming to work...

This is what it normally looks like

#Saves state.
#input_save_state = f2
#Loads state.
#input_load_state = f4

Well actually it's more of a combo of buttons. With my configuration above, if I want to do a Save State I have to hold the "hotkey" which is the Select button and then the "save state" button which is the B button. Then to load the save state I hit both Select + X and to exit the emulator i hit both Select + Start.

Also just to clarify, the "#" tells the emulator to ignore all text after it until there is a carriage return (or new line). I use it to put comments in my configuration files so I can easily decipher it later on haha.

Lastly, with that Adafruit display, you might have to manually set the resolution. I've never messed with that but maybe this thread will help:
