New in SNES9X 1.52 (Jan 17, 2010)

  • IMPORTANT NOTICE: The structure of savestates (also known as snapshots / freeze files) is incompatible with older versions! Snes9x 1.52 cannot read the savestates created by 1.51 or older.
  • Highly acculate SPC700 and S-DSP emulation.
  • Replaced APU emulation cores (SPC700 and S-DSP) with ones provided by Blargg's SNES_SPC library. This renders savestates incompatible with older versions.
  • SPC7110 emulation.
  • Merged bsnes' SPC7110 emulation code. Note that the .rtc file of Far East of Eden Zero is incompatible with older versions.
  • Removed graphics pack support. It's no more necessary.
  • Replaced S-RTC emulation code with bsnes' one to keep the good compatibility of .rtc files between the two emulators. As a result, Daikaijuu Monogatari 2 now outputs the .rtc file, and its .srm file is incompatible with older versions.
  • Added savestate supports for DSP-2, DSP-4, ST-010 and OBC1.
  • Added UPS support.
  • Fixed DSP-4 AI problem.
  • Fixed invalid memory accesses in C4 and OBC1 codes.
  • Fixed invalid memory accesses in BSX codes. My mistake.
  • Fixed the read value of $213e, $4210 and $4211.
  • Fixed the writing of word values at the memory boundary.
  • Fixed the bug that the unnecessary SA-1 emulation continues once any SA-1 games are launched.
  • Removed old color blending codes.
  • Removed too-old Snes96 and ZSNES snapshot support.
  • Updated command-line options.
  • Code cleaning.
  • GTK+ : Added a port of Snes9x to the GTK+ toolkit.
  • Unix : Reconstructed and simplified all the contents. Some features have been removed to be simple, and many options have changed. GTK+ port is recommended for most of Linux users.
  • Fixed corrupted screenshot on Intel Mac.
  • Fixed sudden abort in QuickTime movie export on Intel Mac.
  • Changed sound settings for the new APU core.
  • Changed the default folder which Snes9x looks for to 'Application Support' folder.
  • Changed folder names: 'IPSs' -> 'Patches', 'BIOSs' -> 'BIOSes'.
  • Added Blargg's ntsc filter.
  • Internal changes for Leopard and Snow Leopard.
