SuperSNES9X est un fork avancé de SNES9X, développé par shanytc, qui ajoute de nombreuses améliorations modernes tout en conservant la rapidité et la simplicité du SNES9X original. Il vise autant les joueurs (retroachievements, online) que les créateurs (sprite ripping, hacking, debugging).
Principales améliorations:
РRetroachievements int̩gr̩s
– Kaillera pour le jeu en ligne
– Run‑Ahead pour réduire la latence
– Correction colorimétrique CRT‑like
– Viewer avancé de sprites / tiles pour rippers et map‑makers
РCheat search & editor am̩lior̩s : clic droit, fonctions batch
РAssignation mixte clavier + manette sur une m̻me entr̩e
РD̩bogueur en d̩veloppement
A noter que les fichiers de configuration et sauvegardes sont 100% compatibles entre SNES9X et SuperSNES9X.
Les changements sont:
– Added Per-pixel PPU + per-dot CPU/PPU interleaving
– Fixes mid-LY SCX/BGP/LCDC/WX changes (e.g Animaniacs cloud strip, Balloon Kid title parallax)
– Fixes HBlank-IRQ SCX streaks (e.g Wario Land 2, Balloon Fight)
– STAT IRQs service before PPU advances
– Removed cycle_debt accumulator
– RunFrame runs to vblank past cycle budget so BlitScreen reads complete framebuffers;
– Stopped running a 2nd frame on each CHR/PCT_TRN packet (DK title was at half fps);
– Removed empirical sample-count cap that produced gibberish on some hosts;
– StateLoad no longer wipes sample_head/tail (was discarding runahead audio);
– Skip blit/present during runahead
– Per-opcode SNES→GB sync — added then reverted; aimed at BIOS-mode border corruption at default timing
– Slice-rotation defenses — added then dropped; clamp/phantom-rotation/freeze-capture layers for the 18-slice protocol
– Switched to 4-bank ICD2 protocol — replaced 18-slice;
– Fixed W6001-wobble frame jumps;
– $6000 returns (sgb_row & 0xF8) | (sgb_bank & 0x03);
– $7800 inline planar decode;
– sgb_bank persists across frames;
– Dropped full_frame, full_frame_planar, read_slice, slice_index, r7800_snapshot, freeze_capture defense
– Incompatible with 4-bank (caused stale lcd_ring reads → black flash);
– 4-bank doesn’t need it since sgb_bank tracks actual GB scanline position
– Skip auto-mode throttle so SoundSync can pace SGB without underruns
– In auto frame-skip, WinThrottleFramerate locked to QPC 60.0988 fps;
– SoundSync can only slow the emulator, never speed it up, so QPC vs. host-audio-crystal
drift drained the GB ring → S9xMixSamples zero-padded → crackling/slowdown;
– when SGB owns audio and SoundSync is on, fall through to no-throttle and let SoundSync pace
