Overview¶

Hardware¶

Software¶

Kernel	GPU drivers	Compositor	Interface
Mainline Linux	libmali (GLES 3.2) & Panfrost (GL 3.1/GLES 3.1)	Sway	Emulation Station

Tweaks¶

In Emulationstation system settings you find an overclock setting and undervolt options. The overlock option enables 2 GHz operation. While there are 3 levels of undervolting, where L1 is the least undervolt and L3 is the most undervolt. Undervolting can help performance in higher end emulators such as PPSSPP and Yabasanshiro standalone, due to less thermal throttling. As well as less battery drain on lower end emulators.

Obviously it can't be guaranteed that all specimens can undervolt and hence you may end up with a non-booting or unstable system. If this is occurs, the undervolting can be reversed by:

Inserting the OS SD card into a PC.
Open ROCKNIX partition, and go to the extlinux folder.
Open extlinux.conf text file.
Completely remove the line that starts with FDTOVERLAYS.
Now your device will boot with stock voltages.

Features¶

Feature	Notes

Wifi	Can be turned on in Emulation Station under Main Menu > Network Settings
Bluetooth	Supports bluetooth audio and controllers
LED	Supports selecting from a set of colors or turning the power LED off (choice persists through reboots) Does not support other effects.

Controls¶

RetroArch Hotkeys¶

Button Combo	Action
`SELECT`+`START` ^(x2)	Quit Game
`SELECT`+`R1`	Save State
`SELECT`+`L1`	Load State
`SELECT`+`X(NORTH)`	Open RA Menu
`SELECT`+`Y(WEST)`	Show FPS
`SELECT`+`R2`	Fast-Forward

Notes:¶

By default ROCKNIX will detect your controller and configure RetroArch hotkeys automatically. This is controlled by the "AUTOCONFIGURE RETROARCH HOTKEYS" option in the Settings > Controller & Bluetooth menu. While the option is enabled, RetroArch hotkeys will be overwritten by the above defaults each time RetroArch is launched. If this behavior is not desired that option can be disabled and your user-defined RetroArch hotkeys will be used instead.

Mednafen Hotkeys¶

Button Combo	Action
`SELECT`+`START` ^{(hold for 2sec)}	Quit Game
`SELECT`+`R1`	Save State
`SELECT`+`L1` ^{(hold for 2sec)}	Load State
`SELECT`+`Y(WEST)`	Show FPS
`SELECT`+`R2`	Fast-Forward
`START`+`L1`	Select disc
`START`+`R1`	Eject/Insert disc
`START`+`D-Pad Left`	Decrease save slot by 1
`START`+`D-Pad Right`	Increase save slot by 1
`START`+`L2`	Configure buttons on virtual port 1
`START`+`R2`	Insert coin

Notes:¶

By default ROCKNIX will expand the configuration file according to the first controller mednafen finds. This only happens when the config file doesn't exist (meaning the first time or if you manually delete it). After the initial expansion you are free to customize the controls.

Mupen64Plus-SA (Nintendo 64)¶

Button Combo	Action
`START`	Start
`B(SOUTH)`	A
`Y(WEST)`	B
`Right Analog Up`	C Up
`Right Analog Down`	C Down
`Right Analog Left`	C Left
`Right Analog Right`	C Right
`L2`	Z
`L1`	L
`R1`	R
`SELECT`+`START`	Quit Game
`SELECT`+`R1`	Save State
`SELECT`+`L1`	Load State
`SELECT`+`Y(WEST)`	Take Screenshot
`SELECT`+`B(SOUTH)`	Reset Game

Notes:¶

Z and L button assignment can be changed directly in EmulationStation
- Highlight the game and press X(NORTH)
- Select ADVANCED GAME OPTIONS
- Set EMULATOR to MUPEN64PLUSSA
- Then change INPUT ONFIGURATION
  - Default: L1 = L, L2 = Z
  - Z & L SWAP: L1 = Z, L2 = L
You can also create your own custom controller configuration and add it to /storage/.configs/game/configs/mupen64plussa. Then update INPUT CONFIGURATION to CUSTOM following the same steps as above.

PPSSPP-SA (PSP)¶

Button Combo	Action
`START`	Start
`SELECT`	Select
`A(EAST)`	Circle
`B(SOUTH)`	Cross
`X(NORTH)`	Triangle
`Y(WEST)`	Square
`L1`	L
`R1`	R
`R2`	Save State
`L2`	Load State
`L3`	Open Menu

Hypseus-singe (Daphne)¶

Button Combo	Action
`SELECT`+`START`	Quit Game
`SELECT`	Coin
`START`	Start
`B(SOUTH)`	Button 1
`A(EAST)`	Button 2
`X(NORTH)`	Button 3

Notes:¶

To add/change mapping you can edit /storage/.config/game/configs/hypseus/hypinput.ini under [KEYBOARD] section by changing third number for a function from 0 (disabled) to a corresponding joystick value. You can identify joystick values by running jstest /dev/input/js0 over ssh.

For example the following would assign quit to L1 and pause to R1

[KEYBOARD]
KEY_QUIT = SDLK_ESCAPE 0 5
KEY_PAUSE = SDLK_p 0 6

Global Hotkeys¶

Button Combo	Action
`SELECT`+`Vol +`	Brightness Up
`SELECT`+`Vol -`	Brightness Down
`START`+`Vol +`	Battery Status
`START`+`Vol -`	WIFI Toggle
