The SH4 sets the signaling bit to 0 for qNaN: 7fbfffff instead of the
usual 7fffffff. Same games seem to rely on this.
Fixes Fur Fighters freeze and missing geometry in game.
The -ffast-math gcc option implies the -ffinite-math-only option, which
produces wrong results with Inf and NaN. Use integer math to detect the
sign of float numbers in FTRC to avoid these issues.
Also the upper cut off value for conversion was apparently wrong.
Also fixed the x86 dynarec but not tested.
Fixes wrong car color in Tokyo Xtreme Racer car selection screen.
Pier Solar and the Great Architects CDI uses an unknown type 4 sector of
2448 bytes. This hack allows the CDI to be read. Not sure about the
correctness.
StrideSel and ScanOrder are no longer part of the texture cache key
since that breaks RTT texture matching. But they are updated at lookup
time so they will be used if the tex is updated later.
Fixes RTT-based xfade screens in Skies of Arcadia.
Paletted textures using a 32-bit palette and YUV textures are now
converted to 8888 format, which results in a lossless conversion.
Fixes background texture quality in Alone in the Dark.
In flat shading mode, the third vertex of a triangle defines its color
so we must maintain its index.
Fixes the remaining color polygons seen in Evolution - The World of
Sacred Device.
div32 matching doesn't handle division by zero and edge cases, which
causes crashes with some games.
Setting enabled by default for Pro Pinball Trilogy.
Instead of ignoring TA data if ListInit hasn't been called, call
ListInit then accept the data. The data will still be probably ignored
but end of list interrupts are sent so game won't hang.
Fixes hang in King of Fighters New Wave (Naomi).
Some games do not align TA_ISP_BASE on 1 MB boundary so the rendering
context is not found at render time. Fixes black screen in NFL 2K2, NBA
2K2, Oooga Booga, Floigan Bros. and probably more Visual Concepts games.
Sadly Ooga Booga still crashes.
The previous algorithm to determine the sort mode for TR polys was
faulty. And the sort mode can vary between passes for multipass
rendering. This also removes the need for the hack to support Always
depth mode with autosorted TR polys. Should fix the Resident Evil 3 menu
problem.
Parse modifier volumes similarily to other polys (first, count, params).
Draw all triangles in one shot and use quad to sum up instead of
redrawing entire strip. Use OR operation for open volumes/quads
(Soulcalibur).
There's a texture corruption of the tennis ball and other textures,
notably the players' bags in the first intro sequence. The corruption is
due to render to texture squashing existing textures. Not sure what's
going on but this avoids the texture corruption. The original problem
remains.
