Snes9X 1.56.1


SuperMod and Music Guru
The SNES emulator Snes9X was updated to version 1.56 yesterday and then updated to version 1.56.1 today. Here's what's new:

  • Increased the speed of SA1 emulation to match hardware more closely.
  • Fixed negative SA1 division
  • Changed the location where we poll input to potentially reduce lag.
  • Fixed the interlace fields being swapped after skipping frames.
  • More updates for BS-X support.
  • Updated xBRZ to version 1.6.
  • Added a DMA timing hack for rpgone's Koryu no Mimi translation.
  • Updated HDMA to not update indirect addresses until after transfers are completed.
  • Improved cheats support. This stores cheats in a human-readable and editable format as gamename.cht. Cheats are converted from the old format on load. They can be added in many different formats, but they will convert to the simple address=condition?byte format. Also, now included is mightymo's cheat database, and the ability to match a game and automatically load cheats from it.
  • Don't reset a pending NMI on vblank end. Fixes Super Punch-Out.
  • Redo NMI timing. Fixes Secret of Evermore (PAL).
  • Test for transparency before dithering on SuperFX. This fixes some graphical artifacts in Star Fox.
  • Change some of the SDD1 guesswork mapping. Fixes a Tales of Phantasia hack.
  • Return PPU1 MDR for reads of $2137 instead of CPU MDR. Fixes Mario's Time Machine graphical glitch.
  • Memset less memory for sprite calculations.
  • Don't spuriously update register 14 when running SuperFX. Fixes graphical glitches in Doom.
  • Added a SuperFX clock modifier variable.
  • Write CPU MDR during some DMA and HDMA transfers. Fixes Speedy Gonzales and Funaki Masakatsu Hybrid Wrestler.
  • Calculate next IRQ time in advance instead of continously checking for it.
  • Added some IRQ timing quirks. Fixes at least Marko's Magic Football.
  • Fixed wrong tile selection in offset-per-tile mode.
  • Advance the VRAM pointer even if VRAM writes at the time are invalid.
  • Return 0x80 instead of 0xff in DSP1 simulation. Fixes Powerfest '94 Mario Kart.
  • Initialize controllers on reset. Fixes Looney Tunes B-Ball multitap.
  • Attached APU instruction tracer and made some additions to debugging output.
  • Fix line doubling in interlaced mode.
  • Added support for M.A.C.S. rifle peripheral.
  • Fixed a bug where the MSU1 channels were reversed.
  • Automatic input rate now only works for close multiples of 60Hz.
