Frontends: Arcan 0.4.0 :: AEP Emulation Page - Emulation News

General changes

Monitoring mode now uses the same namespace as themes, can now load .lua crashdumps
The core-engine builds and runs on arm/egl devices (e.g. raspberry PI), no working input layer or resolution switching controls yet. _math performance is horrible before we get working ARMv6 + NEON optimized options.
Frameserver API cleaned up, reworked build-system and source organisation.
Optional avfeed- frameserver added, this is just a skeleton to ease writing custom data sources ( corresponding lua calls are launch_avfeed) and needs to be enabled build-time.
Frameservers can now (except on windows) be built in a split- mode, where each subtype (movie, encode, libretro etc.) gets its own binary.
Alignment issues when running SIMD optimized math adjusted
OSX support partially re-added, no packaging / UI work as of yet.
Monitoring mode changed slightly, instead of forking, we now set envvar and re-exec ourselves to accommodate for systems with broken broken fork() support (seriously OSX...)

LUA API changes

initial API documentation coverage now at 100%, language and descriptive qualities for individual pages still have a lot to go, this will be improved gradually.
system_load now accepts an optional trigger to disable _fatal calls when asked to load a broken script
target_coreopt added to force key,val options to target frameserver
target_verbose hints frameservers and their internal processing to expose more detailed data (e.g. pts/framecount/frameskipping for decode and encode)
define_calctarget added, similar in style to a recordtarget (without any audio) that exposes buffer data as a callback to a provided lua function
target_synchronous disables PTS enforcement and blocks on sync with frameserver and with GPU (only for very specific uses)
exposing lua api to the VM is delayed until just before the themename() entry-point
all C<->LUA functions are now mapped to a LUA_TRACE(luasymbolname) macro (where ctx refers to the lua_State pointer) for engine dev. to ease customized tracing, by default, the macro is just empty.
system_snapshot function added (similar to a crashdump but can be invoked by script dev.)
image_children now returns correct VIDs
more functions aggressively shut down if a broken VID is provided

Libretro frameserver

Support for Core Options
Support for 3D Cores (may cause some problems with certain window managers as we need to spawn full windows to get access to an off-screen FBO)
Improved support for analog devices and filtering
Rollback based input latency masking support added (experimental)

Database tool

Improved builddb times and fixes for libretro core scanning
Now adds support for .descr files in games/target folder to disable and override scanning
