v0.0.2 — Performance & Correctness Update

Changes since v0.0.1

Performance

• gb_tick hot path optimization — TIMA fast-path, inlined cycle counting, branch hints. Reduces per-instruction overhead (~47K calls/bank/frame)
• Tile-batched background rendering — Fetches tile row once, decodes all 8 pixels. ~16x fewer VRAM reads per scanline
• Optimized sprite rendering — Direct VRAM access, pre-clamped pixel loops, early off-screen skip
• 34 missing entry points added — Eliminates all known interpreter fallbacks from tested gameplay paths

Audio

• Smooth underrun fade-out — Audio callback fades from last sample on underrun instead of inserting hard silence, eliminating pops

Bug Fixes

• SRAM save debounce — Saves 5 seconds after last ERAM write instead of spamming every second during RTC updates
• Quiet save logging — No more console spam on successful saves

Requirements

• Windows 10/11 x64
• A legally obtained Pokemon Red or Blue ROM (.gb)
