Full-system Xbox emulator built on QEMU. One tree builds the standalone
|

application and, with the libretro build option, a core in which a shim
|
||||
replaces ui/xemu.c: the QEMU machine runs on its own thread, retro_run pumps
|
||||
the RetroPads into the Duke controllers and blits the NV2A surface into the
|
||||
frontend's framebuffer through an OpenGL 4.0 core context, and content is a
|
||||
.iso or .xiso image that QEMU opens from its full path. Save states are not

implemented, and game saves live inside the hard disk image.

Full-system Xbox emulator built on QEMU. The libretro core is built from
|
||||
libretro's xemu-libretro tree on its libretro branch, which merges
|
||||
Tovarichtch's xemu fork (xemu master with Chihiro support) and keeps the
|
||||
core alone: the standalone UI and packaging are removed. upstream.version
|
||||
names the upstream version merged. Content is an Xbox disc image (.iso,
|
||||
.xiso) or a Chihiro netboot image (.bin), opened from its full path. An
|
||||
Xbox disc boots an Xbox, any other image a Chihiro.

The core reads the same four files from the frontend system directory, each

under a name picked by a core option that offers a default and a few

The core has no option for these paths. It looks for each file in

flash ROM is tried as Complex_4627v1.03.bin, then Complex_4627.bin. A

missing boot ROM or flash ROM fails the load. A missing hard disk image

is written there from the formatted image the core carries

(data/xbox_hdd.qcow2), and the EEPROM is left to the machine, which
|

generates one. Shader caches and patches live in system/xemu/ too.

A Chihiro boots only its own BIOS, system/xemu/Chihiro/chihiro_xbox_bios.bin,

flash and the three EEPROMs are read beside it by their MAME names, and a
|
||||
missing one, or a BIOS that is not that image, leaves the machine paused
|
||||
with a message naming it. The network firmware ver1305.bin is read from
|

the same folder when it is there, and only a linked cabinet needs it.
