Arduboy FX simulator (ATmega32U4 + SSD1306 + W25Q128). All boot code
|
|
embedded as C arrays: Caterina/Arduboy3K bootloaders for D1/D2/E2
|
|
hardware revisions and flashcart header. EEPROM and flash state handled
|
|
via RETRO_MEMORY_SAVE_RAM. The libretro port never accesses the system
|
|
directory. firmware_count = 0.

|
note: |
|
|
All bootloaders are compiled from Intel HEX into C arrays at build
|
|
time. The core selects the game or menu variant at reset depending
|
|
on whether a flashcart image was loaded and the boot_to_menu config
|
|
flag (absim_arduboy.cpp:142-158). The bootloader is written to the
|
|
top of the ATmega32U4 program memory at the address defined by the
|
|
BOOTSZ fuse bits (absim.hpp:811).

|
|
note: |
|
|
Empty flashcart header written to the first 1536 bytes of the
|
|
W25Q128 flash image during initialization. This is not a BIOS
|
|
file -- it is the default flash content the Arduboy FX expects
|
|
at the start of external storage.
