Squarepusher proposes a new version of FBANext, after FB Alpha (Final Burn Alpha). As a reminder, this is a multi arcade emulator based on the source code for Final Burn.

Changelog focusing on changes for developers, we provide it untranslated. The amendments mainly improve the overall operating speed.

- (PS3) Added waterpaint-normalcontrast.cg, waterpaint-normalcontrast-scanline.cg, waterpaint-highcontrast.cg,
waterpaint-highcontrast-scanline.cg shaders
- (PS3) Optimized crt.cg shader - now runs at 60fps (fullspeed) at 1080p (1920x1080). Also added crt-highgamma.cg.
- (PS3) Texture references used - far faster graphics code as a result. Also adapted refreshwithalpha so that it
looks the same as it did before without texture references.
- (PS3) Added all the shaders added inbetween r423 and the custom versions
- (PS3) Replaced inlineASM in burnint.h with intrinsic so that it can be compiled with SNC. Also commented out
little endian functions in blargg_endian.h to get SNC to work
- (PS3) Commented out all exceptions and try - catch blocks in files such as ticpp.cpp and others - SNC by default
works with exception support disabled - also exceptions have performance overhead - commenting out the exceptions
and the try-catch blocks for both GCC and SNC increased performance.
- (PS3) Got rid of virtual function call overhead in classes that inherited from a base class with virtual function
definitions - such as the Cellframework Audio driver, and FBA's aud_audio.h itself. Led to measurable performance
increases and lag reduction.
- (PS3) Better button responsiveness - in PS3/run.cpp, for some reason button input was only being registered one
out of every three frames - commented that out. There were tons of other branches in the interface code that are
unnecessary - checking for bDrivOkay for instance in video_interface and vid_psgl - that were commented out for
PS3. This could similary be applied to FBA 360 for some performance gains - same with the elimination of virtual
function call overhead.
- (PS3) Menu scrolling with the D-pad/analog stick in the ROM browser/settings menu/ingame menu by pressing and
holding directional keys.
- (PS3) Shaders now receive three additional input params for the main vertex program (main_vertex). This
allows us to offload some more calculations from the fragment shader which leads to increased performance.
- (PS3) Added back ability to go to Service menu by pressing R3 button.
- (Core) - Rygar driver colors are restored again to normal colors - during the update to FBA beta, a swapword
statement was left out.
- (PS3) Makefile works now for either SNC or GCC. Change CELL_BUILD_TOOLS to set either of the two. The best
speed I currently get with GCC for some odd reason.
- (PS3) Makefile and preprocessor statements in the code now let you compile the source and have it detect
your SDK version automatically.
- (PS3) There is a special debug mode you can activate (CELL_DEBUG_CONSOLE = 1) where a Telnet server will
be running in the background which you can telnet into - in this mode, you can track variables and/or dump
screenshots on the HDD.
- (PS3) Better speed, far less lag as a result of all of the above.
PS. Every change above only affects the PS3 version.
