Koriki/Batocera Lite for RG35XX 1.0.2 update - 20231220

This is version 1.0.2 of Koriki/Batocera Lite for the RG35XX, it's an incremental update so you will need to install v1.0.1 first. This version includes among other things the possibility of changing launchers and the main capability of batocera, USB for gamepads and wireless USB dongles, and consistent charging and leds behavior for all hardware revisions. See the changes below to know more.

Important: If you get an ERROR 256 when trying to start a game from EmulationStation, mount the SDCARD on your computer and create a folder system/logs on the last partition of the SDcard (SHARE).

Some changes:

2023/12/20:

• Fixed reboot/shutdown from menu (simplemenu)
• Added system/logs folder during installation. If you are reusing an existing card and have issues with error 256, see the important note above and create the folder manually.

2023/12/17:

• Included both simplemenu and EmulationStation launchers
• Changed completely the kernel and init mechanism to resemble the stock one:
  • Leds should now work consistently
  • Battery should report charge correctly
  • Battery charge icon is now displayed when the unit is connected to the power
  • This version should work with all RG35XX hardware revisions
• USB port should now work:
  • USB gamepads should work, although those can only be mapped in Simplemenu
  • USB memories also work
  • USB Wifi adapters now work. Currently only EDIMAX EW-711Un (rtl8192cu based) and TP-Link W725N (rtl8188us/eu based) work. You will need to use EmulationStation to configure the wireless network
• ADB can be disabled/enabled via Simplemenu menu

How to change the default launcher?

Create a file [SHARE]/system/customlauncher (*) with one of these entries in plain text:

• simplemenu: launches the standard Koriki Simplemenu launcher
• emulationstation: launches Batocera EmulationStation
• retroarch: Regular retroarch (like Lakka).

NOTE (*) If you are using 2 sdcards, the file needs to be added to the SHARE partition of your second SDCARD, if you are using one, to the last partition (SHARE) of the first SDCARD).

Installation:

• This release is an update release
• You need to have koriki 1.0 or 1.0.1 installed on a SDCARD
• Mount the SDCARD on your computer
• Extract the archive from this release and copy the contents of the folder into the first partition of the SDCARD (you should see Batocera-conf.conf, boot, etc.)

Koriki for RG35XX Beta 0.9.1

Introduction

This is probably the last major public beta release of Koriki for the RG35XX before 1.0 is released. No major changes (other than bug fixes) are expected from this 0.9 to 1.0.

Note that this is a beta release, so while the system is usable there may be issues that still need to be solved. Use the Discussions Page to discuss any issues you may find, and create issues in the Issues Page

Update 20230717:
A new bootfix has been added for those units that are stuck in the boot splash screen. Also for those that have applied a previous bootfix but the volume keys don't work. You can download the bootfix below.

Installation:

• Flash the koriki-rg35xx image to a SDCARD using balena etcher or a similar software
• Boot with the SDCARD. The first time the firmware will expand the second partition and copy some firmware files to that partition
• Important: this version now uses FAT32 for the second partition, so it should be accessible on Mac/PC without any dedicated software
• If you use a second SDCARD, the system will install those files in the last partition of the second card
• Note that the first time the system boots it will take a bit longer to expand the card and copy files over. Even when the menu is up, there will be a few seconds when the system will be a bit slow because it's adding the virtual memory image
• After the first boot the system will create some configuration folders as well as the roms and bios folders. Add your roms to the roms folder, and your bios to the roms folder.

Update from previous installations:

• NOTE: If you installed v0.7 or higher, it's safe to use the update file. If you installed v0.6 or a previous version, you should install the full image instead since the partition tables have changed.
• Uncompress the file boot.tar.xz, and replace the contents of the first partition of your SDCARD image with this one (you should see files like uImage, ramdisk.img, boot folder, etc.)
• If you run into issues with content not starting or any other issue, rename your system folder (from the last partition of your main SDCARD or your second SDCARD), and start again.

IMPORTANT

• If you use a second SDCARD that you have previously used with koriki for RG35XX, please rename your system folder, and start again.
• Some RG35XX boards have issues booting koriki. Download the archive bootfix_for_revision_v6c.zip, extract it, and copy the files uImage and kernel.dtb to the first Koriki SDCARD partition (overwriting the existing ones). Note that while that fix may solve boot issues, it may introduce some inconsistencies regarding controls like volume keys.

Charger behavior:

• The charging logic is slightly different from the one in the stock firmware (or Garlic). The system reimplements the charger logic that is performed via software and not via hardware in this system.
• Shutdown:
  • If the charger power cable is connected to the USB C port, once the system is shutdown it will boot into the charger mode. You will briefly see a battery symbol and the system will seem to be off but the charger led will be on (orange). To boot from this state, briefly press power key.
  • If the charger cable is not connected, the system will be off completely. To boot again from this state you need to press the power button a few seconds and the system will boot.
• Reboot:
  • The system will reboot as expected

ChangeLog:

2023/07/07:

• Added Watara Supervision (potator) core
• Added Intellivision (freeing) core
• Added Atari 7800 (prosystem) core

• Fixed a bug that showed the mouse cursor when launching a rom
• Fixed a bug where simplemenu didn’t return to the same gamelist location after closing a rom/port

2023/07/04:

• Fixed controls getting stuck in one direction. This was mostly visible on shoot’em up games like 1944, Last Resort, etc.
• Removed evmapy dependency. Added joystick support to simplemenu so evmapy is no longer needed to create key events from joystick events
• Retroarch no longer has duplicated or incorrect events due to the removal of evmapy and new input mappings.
• Retroarch key mappings/hotkeys have changed to be consistent with Koriki on the Miyoo Mini:
  • MENU + A: Pause
  • MENU + B: FastForward Toggle
  • MENU + X: Menu
  • MENU + Y: Reset Content
  • MENU + L1: Save Save State
  • MENU + R1: Load Save State

• Initial wifi work (not yet working via configuration files).
• Bumped version to Beta 0.9

2023/06/19

• Added timeout for POWER button press. System no longer shutdowns immediately when the button is pressed, now it needs to be pressed about 3s
• Fixed volume increasing to 100% when unit was shut down via power button
• Fixed brightness control combo (MENU+VOL+/-)
• Fixed audio volume keys if you use adb_uImage (mixer was different between adb_uImage and uImage)

• Added launcher for eduke32 (DukeNukem3D)
• Bumped version to Beta 0.8

2023/06/16

• Modified the FP flags from VFP3-D16 to NEON due to some performance issues detected in PCSX rearmed core. This should bring some performance improvements
• Recompiled all cores with the new architecture
• Updated full buildroot packages to synchronize to the latest batocera build
• Removed some unnecessary patches. Note that there may be some inconsistencies with previous releases, please report those in the discussions page, discord, or create issues if the problem is well defined
• Improved charging logic. When connecting a power cable when the console is off, the console will enter into charging mode without booting into koriki
• Added PCSX standalone (note, currently is not possible to exit the emulator, if anyone knows how to quit, please let me know)
• Added default mupen64 controls (you can exit the emulator with START+SELECT)
• Added ATC theme in Spanish (Thanks to @albgr1979) (theme switching should now work)
• Enabled USB for controllers and some other devices. By default this release works with USB devices like gamepads, USB Wifi and USB Ethernet. However, please not that USB wireless is not currently configured.
  • Note: If you want to use ADB, copy over adb_uImage into uImage
• Improved input handling by updating the input driver to the latest garlic gpio module (quick movement from L to R or U to D should not leave the key stuck in the initial direction)
  • Note: there's a regression with the power button due to the new input driver. Use the simplemenu menu to shutdown/reboot

2023/06/13

• Fixed swap virtual memory generation, it has its own dedicated partition now, should be much more efficient and not impact FAT32 partitions
• Added additional ports location
• Added SDL VT patch to solve some issues with some ports not returning to simplemenu (thanks @JohnnyonFlame)

2023/06/08

• Fixed simplemenu NO GAMES FOUND message. Now it will go back to the last selection after a game is closed or after restart

• If you run into issues with content not starting or any other issue, rename your system folder (from the last partition of your main SDCARD or your second SDCARD), and start again.

IMPORTANT

• If you use a second SDCARD that you have previously used with koriki for RG35XX, please rename your system folder, and start again.
• Some RG35XX boards have issues booting koriki. Download the archive bootfix_for_some_revisions.zip, extract it, and copy the files uImage and kernel.dtb to the first Koriki SDCARD partition (overwriting the existing ones). Note that while that fix may solve boot issues, it may introduce some inconsistencies regarding controls like volume keys.

Charger behavior:

• The charging logic is slightly different from the one in the stock firmware (or Garlic). The system reimplements the charger logic that is performed via software and not via hardware in this system.
• Shutdown:
  • If the charger power cable is connected to the USB C port, once the system is shutdown it will boot into the charger mode. You will briefly see a battery symbol and the system will seem to be off but the charger led will be on (orange). To boot from this state, briefly press power key.
  • If the charger cable is not connected, the system will be off completely. To boot again from this state you need to press the power button a few seconds and the system will boot.
• Reboot:
  • The system will reboot as expected

ChangeLog:

2023/07/04:

• Fixed controls getting stuck in one direction. This was mostly visible on shoot’em up games like 1944, Last Resort, etc.
• Removed evmapy dependency. Added joystick support to simplemenu so evmapy is no longer needed to create key events from joystick events
• Retroarch no longer has duplicated or incorrect events due to the removal of evmapy and new input mappings.
• Retroarch key mappings/hotkeys have changed to be consistent with Koriki on the Miyoo Mini:
  • MENU + A: Pause
  • MENU + B: FastForward Toggle
  • MENU + X: Menu
  • MENU + Y: Reset Content
  • MENU + L1: Save Save State
  • MENU + R1: Load Save State
  • MENU + L2: Next Save State
  • MENU + R2: Previous Save State
  • START + SELECT: Quit Game
• Created SDL_GAMECONTROLLERCONFIG configuration file in ~/.config/gamecontrolerconfigdb.txt
• Fixed the simplemenu framebuffer glitch when launching roms/ports
• Fixed simplemenu background changing when selecting cores in simplemenu (pressing select to access game menu)
• Fixed simplemenu favorites not being created
• Fixed first SDCard SHARE partition not getting properly expanded (not visible on MacOS, etc.)
• Added RNDIS support (thanks @JohnnyonFlame). You need to use the adb_uImage and then create a script that calls usbmond.sh RNDIS.
• Initial wifi work (not yet working via configuration files).
• Bumped version to Beta 0.9

2023/06/19

• Added timeout for POWER button press. System no longer shutdowns immediately when the button is pressed, now it needs to be pressed about 3s
• Fixed volume increasing to 100% when unit was shut down via power button
• Fixed brightness control combo (MENU+VOL+/-)
• Fixed audio volume keys if you use adb_uImage (mixer was different between adb_uImage and uImage)
• Fixed HDMI audio. Note that HDMI cable needs to be plugged in before boot for HDMI to work
• Added PCSX standalone configuration
• Added Devolutionx (Diablo) gamepad support
• Re-Added KM MAME 2003 xtreme core (removed by mistake in 0.7.3)
• Added libretro CROCODS core (Amstrad CPC)
• Added libretro quickness core (NES)
• Added libretro bk (elektronika PDP) (currently broken)

• Added libretro RACE (NGPC)
• Added launcher for eduke32 (DukeNukem3D)
• Bumped version to Beta 0.8

2023/06/16

• Modified the FP flags from VFP3-D16 to NEON due to some performance issues detected in PCSX rearmed core. This should bring some performance improvements
• Recompiled all cores with the new architecture
• Updated full buildroot packages to synchronize to the latest batocera build
• Removed some unnecessary patches. Note that there may be some inconsistencies with previous releases, please report those in the discussions page, discord, or create issues if the problem is well defined
• Improved charging logic. When connecting a power cable when the console is off, the console will enter into charging mode without booting into koriki
• Added PCSX standalone (note, currently is not possible to exit the emulator, if anyone knows how to quit, please let me know)
• Added default mupen64 controls (you can exit the emulator with START+SELECT)
• Added ATC theme in Spanish (Thanks to @albgr1979) (theme switching should now work)
• Enabled USB for controllers and some other devices. By default this release works with USB devices like gamepads, USB Wifi and USB Ethernet. However, please not that USB wireless is not currently configured.
  • Note: If you want to use ADB, copy over adb_uImage into uImage
• Improved input handling by updating the input driver to the latest garlic gpio module (quick movement from L to R or U to D should not leave the key stuck in the initial direction)
  • Note: there's a regression with the power button due to the new input driver. Use the simplemenu menu to shutdown/reboot

2023/06/13
