Hi,

I just got my first raspberry pi yesterday and I bought with the
intention to run retropie on it and play all the games from my
childhood. I bought 2 usb generic snes controllers off amazon for
this. So far I seem to have gotten it configured and have roms
transferred to it an playable. I currently have 2 problems.

1. I have managed to get the controllers to work in the games and playable on several NES and SNES games and also 1 or 2 mame games. I bought this with the hope that I wont need a keyboard once I have it configured. The biggest hurdle for that so far is the inability to exit out of a game and select another with out having a keyboard plugged in. I have spent several hours today searching this forum and google to try to fix this and so far no luck. I think I found the right file but maybe not. /opt/retropi/emulators/Retroarch/configs/

input_device = "2Axes 11Keys Game  Pad"
input_driver = "udev"
input_b_btn = "2"
input_y_btn = "3"
input_select_btn = "8"
input_start_btn = "9"
input_up_axis = "-1"
input_down_axis = "+1"
input_left_axis = "-0"
input_right_axis = "+0"
input_a_btn = "1"
input_x_btn = "0"
input_l_btn = "4"
input_r_btn = "5"

input_enable_hotkey_btn = "8"
input_exit_emulator_btn = "4"
input_save_state_btn = "0"
input_load_state_btn = "1"

2. The other ting I would like and not even sure where to look is when I was a kid I remember these games being a little more crisp. I know i am on a hd 1080p tv and not an old tube tv but some of the things are so blurry if you didnt know what they were in the original then you would have no clue what it is now. Is there any way to crispen up the graphics to make it closer to what I remember. I have no idea where to look for this.

Thanks in advance
