| Entry | What it does |
|---|---|
| Controller › | Opening combo, autofire, Home combo |
| Diagnostics › | System information and logs |
| Toggle Write Access on USB | Makes the USB/SD drive writable even if you don't keep your saves on it — it's read-only otherwise. Not needed if you use USB saves. Only shown with a USB/SD drive connected |
| Epilepsy protection (NES) | The console's own dimming of fast flashes in NES/Famicom games. On by default; turn it off to see games exactly as they were. NES/Famicom only |
| Clear Cache | Asks the kernel to free cached memory. The system handles this by itself, so it's rarely needed |
| Module Uninstaller | Remove hmods from the console |
| Entry | What it does |
|---|---|
| Change Options Button Combo | Hold the buttons you want to open the menu with. Restart the console afterwards. Replaces the automatic L+R / B+Down |
| Autofire | Turbo for the controllers |
| ↳ Fast / Normal / Slow speed | Turbo speed |
| Use X/Y as turbo A/B | X and Y act as turbo A and B |
| Home menu button combo | Turns off the combo that takes you from a game back to the Home menu, so you can't press it by accident |
| Start on 2nd controller | Famicom Mini only. The 2nd Famicom controller has no Start button; this lets it send one |
Everything except the opening combo applies right away.
| Entry | What it does |
|---|---|
| System Information | Console type and region, hakchi/kernel/boot versions, firmware, free space on NAND and USB/SD, size of your saves |
| Display Temp | CPU temperature |
| Run Top | CPU and memory use and the running processes |
| Benchmark Tool | Mounts, CPU and RAM information, shown in 4 parts |
| RetroArch Debugger (USB logs) | Runs RetroArch in verbose mode and saves its config and log to /media/data/log/
|
| Dump File Structure (to USB) | Writes every file and folder, with permissions and links, to /media/data/log/Hakchi_file_structure.log
|
| Save kernel log (to USB) | Writes the kernel log (dmesg) to /media/data/log/dmesg.log
|
The USB entries only show up with a USB/SD drive connected. These logs are what to attach when you report a problem.
The RetroArch Debugger is meant for testing cores, configs and themes; some RetroArch features may not work while it runs.
Removes installed hmods without a PC.
- Installed mods are on the left, the ones you queue for removal on the right.
- A adds the selected mod to the queue, B takes the last one off.
- Start exits. With mods in the queue it asks to confirm: Start + Select removes them, B cancels.
It lists hakchi's own modules too. Only remove mods you installed yourself.
