|
||||
* __Search drives and folders__: Just press R+A on the drive / folder you want to search.
|
||||
* __Compare and verify files__: Press the A button on the first file, select `Calculate SHA-256`. Do the same for the second file. If the two files are identical, you will get a message about them being identical. On the SDCARD drive (`0:`) you can also write an SHA file, so you can check for any modifications at a later point.
|
||||
* __Hexview and hexedit any file__: Press the A button on a file and select `Show in Hexeditor`. A button again enables edit mode, hold the A button and press arrow buttons to edit bytes. You will get an additional confirmation prompt to take over changes. Take note that for certain files, write permissions can't be enabled.
|
||||
* __View text files in a text viewer__: Press the A button on a file and select `Show in Textviewer` (only shows up for actual text files). You can enable wordwrapped mode via R+Y, and navigate around the file via R+X and the dpad.
|
||||
* __View/edit text files in a text editor__: Press the A button on a file and select `Show in Text Editor` (only shows up for actual text files). You can enable wordwrapped mode via R+Y, and navigate around the file via R+X and the dpad.
|
||||
* __Chainload FIRM payloads__: Press the A button on a FIRM file, select `FIRM options` -> `Boot FIRM`. Keep in mind you should not run FIRMs from dubious sources and that the write permissions system is no longer in place after booting a payload.
|
||||
* __Chainload FIRM payloads from a neat menu__: The `payloads` menu is found inside the HOME button menu. It provides any FIRM found in `0:/gm9/payloads` for quick chainloading.
|
||||
* __Inject a file to another file__: Put exactly one file (the file to be injected from) into the clipboard (via the Y button). Press A on the file to be injected to. There will be an option to inject the first file into it.
