- ABOUT
luma is an emulator for the AGB - Game Boy Advance - platform.
- USAGE
luma [image] [bootloader]
Invoke the emulator via the 'luma' command.
- CONFIGURATION
The emulator tries to read the configuration file at '${HOME}/.luma.toml'. If
this file is found, the following fields are read (if present):
luma:
* version: (Integer) The version of the configuration file (0)
device:
* bootloader: (String) The path to the bootloader file (home-relative)
* image: (String) The path to the image file (home-relative)
video:
* scale: (Integer) The scale modifier applied to the screen (min 1; max (2^32-1))
These settings are overwritten by terminal parameters (see USAGE).
- COMPATIBILITY
Currently, the emulator supports the following ARM instructions only. Others
will be skipped.
* b{cond}{l}
* bx Rm
* ldr{cond} Rn, +/-offset
* mov{cond} Rd, Rn
* mov{cons}s r15, Rn
* str{cond} Rn, +/-offset
When the virtual processor boots, the default mode is the sys mode. As no
supported instruction can change this mode, this is also the only mode for now.
The entire memory space (0x00000000 to 0x0E010000, inclusive) is available,
however, no I/O-mapped addresses are currently functional.
Improved support is, of course, planned.
