Snes9x v1.63.11 has been released. Snes9x is a free and portable Super Nintendo Entertainment System (SNES) emulator that enables you to enjoy most games made for the SNES and Super Famicom Nintendo consoles on your PC or workstation. This includes numerous titles that were exclusive to Japan. The development of Snes9x involved over three years of part-time coding, debugging, and a sprinkle of humor (the divorce comment was just a joke). The emulator is written in C++, featuring three assembler CPU emulation cores for the i386 Linux and Windows versions.

Snes9x changelog:
Introduced a self-contained Game Boy / Game Boy Color core (SM83 CPU, PPU, APU, timer, joypad, MBC1/3/5, battery SRAM, save
states).
Integrated .gb / .gbc (and their zipped versions) into Snes9x’s loader, directing them to the SGB subsystem rather than the 65816
parser.
Added true SGB1 / SGB2 BIOS mode operating on the 65816 along with the GB core, featuring an ICD2 bridge.
Implemented the SGB command set: palettes (PAL01/PAL23/PAL_TRN/PAL_SET), attributes (ATTR_BLK/LIN/DIV/CHR/SET/TRN),
custom borders (CHR_TRN + PCT_TRN), MASK_EN, MLT_REQ.
Refined the audio path: GB APU mixed per mode, accurate pitch via Bresenham cps, mode-sensitive sample cap, SGB1
vs SGB2 vs DMG clock differentiation.
Added BIOS-mode SOU_TRN ($09) capture + SPC mix, making cart-uploaded voice clips like Donkey Kong ’94’s “Help! Help!”
audible.
Introduced a BIOS menu (No BIOS / SGB1 / SGB2) with automatic detection.
Resolved RetroAchievements GB/GBC hash recognition issues and routed RA memory reads through GB-side WRAM/HRAM/cart ROM/SRAM.
Fixed game-breaking issues: Tetris Plus serial IRQ, Pokémon Yellow STAT-while-LCD-off hang, joypad nibble
swap, BIOS-mode 2× over-stepping, $7800 row-ordering, and scroll drift issues, File→Reset crash, cheat-search NULL deref.
Embedded SGB1 and SGB2 GB-side boot ROMs, sourced from LIJI32/SameBoy under the Expat (MIT) license, as they are essential
due to most publicly-dumped sgb*.boot.rom files being standard DMG boot ROMs that only show the Nintendo logo; the SGB BIOS
requires a boot ROM capable of sending the 5-packet SGB handshake (an LD A, $F1 sequence near $3E F1 indicates this). SameBoy
provides proper SGB-specific variants. Without those, BIOS mode gets stuck on the splash screen.
Ensured license compliance by including the SameBoy Expat license text alongside the embedded ROMs.
