⚙️ Improvements

FIFO Crash are fixed ! (TA_ARENA_FIX, default = on)

Some games (or just sometimes somes level) crashes (reported as "FIFO" in dolphin).

This bug has been present since early NullDC4Wii release.

It may gain a few extra FPS/% but I'm not sure

It SHOULD FIX :

• 18 wheeler
• Castlevania HALL stage
• Demolition Racer
• Magforce racing
• Moho
• NHL 2k
• South Park Rally
• Test Drive 6 (2 players mode)
• World Series Baseball 2K2 ?

Fix #16
`

Decal_fix Preset (default on)

This fixes Soldier Of Fortune gameplay enterely black. May fix other games

gxRend: decal_fix preset - TSP Decal (ShadInstr 0) ignores vertex colour (GX_REPLACE)

Soldier of Fortune draws its level and lightmap pass as Decal polys with colour 0;
GX_MODULATE turned the whole level black. Default on; [SCN] gets a [SIG] state census.
Dolphin-confirmed.

IDLE Hook (default on)

Speed enhancement, tested on sega tetris, ok

decoder: idle_hook preset - Sega "while (busy) hook()" wait loop ends its slice after one turn (Sega Tetris, ChuChu)

AICA_REL_CULL (default off)

Speed enhancement by lowering audio precision. Could help grab a few % speed in some games.

aica: aica_rel_cull preset - per-game speed trade, end Release fades below -72/-60/-48 dB (Sega Tetris = 60)

Flash broadcast fix

fix South Park Rally PAL not launching on ntsc bios (and probably other games) with flash_broadcast=disc parameter

flash_broadcast: judge GDIs by their real IP.BIN area, not the "JUE" the reader patches in.

thanks @iamsh4 !

TA_CTX_FIXED (default on)

Fix weird vertices in Magforce racing (probably in other games too)

gxRend: ta_ctx_fix preset - a render of the finished TA list skips the next list already being built (issue [#16](https://github.com/BenoitAdam/nullDC4Wii/issues/16) flicker)

🔊 cdda_clock (default ON) + sound_clock (Default OFF)

Even if a game has 90% speed, the music is played at full speed !

audio: cdda_clock + sound_clock presets - music keeps its real tempo when emulation runs below 100%
