| I began working on bsnes on October 14th, 2004. I am releasing bsnes v0.018 today to celebrate bsnes' two year anniversary. Please note that this release incurs a ~15% speed reduction since v0.017, due to IRQ and S-SMP timing improvements.
Changelog:
• Fixed many critical errors in IRQ timing, should be *very* close to real hardware now
• Corrected major CPU timing bug involving CPU I/O condition 4
• Corrected bug with generic HiROM / LoROM memory maps
• Corrected bug involving HDMA indirect channel termination [anomie]
• OAM address reset now occurs when screen display is enabled, per recent research
• Readded full DMA, HDMA and HDMA init bus sync timing
• Added preliminary emulation of S-SMP $00f0 TEST register (6 of 8 bits are supported)
• Readded emulation of known timing differences between CPU revisions 1 and 2
• Config file can now control scanline-based PPU render position. This will only be needed until a proper dot-based PPU renderer is added
• Removed core debugging hooks so that debugging console can remain in public releases, it now functions as a tracer and memory editor
• Config file paths once again work correctly even if missing trailing backslash
• Video configuration simplified, sorry in advance to those who enjoyed the profile mode used before
• Added new configuration screen to control some emulation settings
• Replaced bsnes program icon with a much nicer one [FitzRoy]
• Optimized memory speed detection algorithm
• Preliminary UPS soft-patching support (do not use this yet!)
• Decreased memory usage and optimized generic libraries used by bsnes (/src/lib)
• Now caching OAM by one line, somewhat similar to a real SNES. Fixes Winter Gold, but causes line rendering error in Mega lo Mania
• Lots more, as usual
The following games have been fixed since v0.017 by the above bugfixes:
• Battle Blaze (J, U)
• Circuit USA (J)
• F1 Grand Prix (J)
• Funaki Masakatsu no Hybrid Wrestler - Tougi Denshou (J)
• Jumbo Ozaki no Hole in One (J)
• Mahjongg Taikai II (J)
• RPG Tsukuru - Super Dante (J)
• Robocop Versus The Terminator (U, E)
• Sink or Swim (U, E)
• Street Racer (J)
• Touge Densetsu Saisoku Battle (J)
• Winter Olympics (U, E)
