Обновился свежий эмулятор Sega Saturn - Ymir.

New features and improvements
- Debugger: Add Priority Stack to VDP2 debug overlay
- VDP2: Various performance optimizations to the software renderer, improving performance in graphics-bound games (especially in high resolution modes). Technical details:
 - RBG1 was being unnecessarily rendered when NBG0 was enabled and RBG1 was disabled
 - Remove redundant transparency bit since priority zero acts as transparency
 - Remove various unused function arguments, reducing CPU register and stack pressure
 - Pass down VDP2 register references as arguments rather than fetching them from scratch everywhere
 - Reuse line data (i.e. skip recomputing lines) when rendering vertical mosaic
 - Bit-pack character pattern data in a single 32-bit value
 - Microoptimize scroll coordinates calculations
 - Rotation parameter table calculations:
  - Specialize calculations for (1) no coefficient table, (2) per-line coefficient table and (3) per-dot coefficient table
  - Hoist coefficient table enable and per-dot coefficients checks out of the loop
  - Make the inner loops SIMD-friendly
  - Avoid unnecessary computation of transparency and line color screen data if they are disabled
 - Microoptimizations to the compositor function:
  - Layer sorting now uses a combined key
  - Gather layer data in one single loop
  - Pixel fetching is now templatized and some bail out checks are done earlier
  - Color offset calculation enable flag is cleared in the fetch loop if no offset is actually applied

Fixes
- Debugger: Various SH2 stack analysis fixes
- Game DB: Add slow VDP1 flag to Funky Fantasy to fix slow FMVs
- Media: Detect postgaps in data tracks when the CUE sheet doesn't explicitly announce them. Fixes audio track shifts in bad Virtua Fighter 2 dumps
- Media: Fix PREGAP/POSTGAP handling in CUE/BIN dumps. Fixes shifted audio tracks in games dumped with ImgBurn
- SH2: Fix illegal slot instruction exception handling
- VDP1: Add game-specific flag for skipping command processing if the top of the table is empty. Enable it exclusively for Sekai no Shasou kara - I Swiss-hen - Alps Tozantetsudou no Tabi. Fixes missing graphics in Gungriffon
- VDP1: Disable early polygon drawing termination when rendering polygons when user clipping mode is inverted. Fixes clipped polygons around the minimap in Machine Head
- VDP1: Implement simple infinite loop detection. Fixes slowdown in the Mojave Desert stage (1-2) in Gale Racer
- VDP2: Apply color calculations to transparent sprite mesh on layer 0. Fixes stripes on ground plane in Gungriffon
- VDP2: Apply color offset to transparent sprite mesh on layer 0 in a separate step. Fixes missing spotlight in the Colonel battle in Mega Man X4
- VDP2: Fix VRAM access calculations when RBG1 is enabled. Fix missing car graphics regression in Gale Racer
- VDP2: Fix and use line color screen calculation ratio when LNCL is inserted. Fixes text background issues in Doukoku Soshite
