# Uzem emulates the Uzebox, an open-source 8-bit game console based on an
|
|
# ATmega644 AVR microcontroller. The console was designed by Alec Bourque (Uze)
|
|
# and all hardware/software is open-source.
|
|
#
|
|
# No BIOS or firmware files are required. The core loads .uze ROM files directly
|
|
# into progmem (uzem_libretro.cpp:254-286). The .uze format includes a "UZEBOX"
|
|
# magic header followed by a RomHeader struct (uzerom.h) and raw program data.
|
|
#
|
|
# The standalone uzem (oldsrcs/uzem.cpp:90) has a --boot flag that sets PC to
|
|
# 0xF000 for bootloader mode, but this is NOT exposed in the libretro port.
|
|
# The libretro core has no retro_environment calls for RETRO_ENVIRONMENT_SET_SYSTEM_DIR
|
|
# or any firmware loading paths.
|
|
#
|
|
# SD card emulation uses RETRO_ENVIRONMENT_GET_CORE_ASSETS_DIRECTORY
|
|
# (uzem_libretro.cpp:186-192) for virtual FAT16 filesystem access via SDEmulator.cpp,
|
|
# but this is optional game data, not system firmware.
|
|
#
|
|
# The .info file declares no firmware entries.

notes:
|
|
open_source_console: >
|
|
The Uzebox is fully open-source hardware and software. There is no proprietary
|
|
BIOS or bootloader required. Games are self-contained .uze files that include
|
|
all code needed to run on the ATmega644 MCU emulation.
|
|
sd_card: >
|
|
Some games use SD card access for loading assets. The core reads from the
|
|
libretro core assets directory to emulate a FAT16 SD card, but this is game
|
|
data, not system firmware.
|
|
standalone_bootloader: >
|
|
The original standalone uzem supports a --boot flag for bootloader mode
|
|
(PC starts at 0xF000 instead of 0x0000). This feature is not available in
|
|
the libretro port.
