PSXeven v0.17 WIP

posted in Emulator Release by narvick on Jun 26th, 2003

Xeven has released a new version of his Playstation emulator, PSXeven! Here's what's new:
  • Enabled interpreter mode. It was previously too slow to be of any use for running games. But due to optimizations done, it's over 2x faster now. You can swap between interpreter and translator mode anytime as well
  • Enabled disassembler, you can enable/disable it by using F7. Enabled this one so that some can send me more useful info
  • Implemented branch delay emulation in the interpreter. No need to use patches for Tekken 2 when running in interpreter mode
  • Added savestate manager. It can be used to delete/browse/load your current savestates
  • Fixed memory allocation bug, which caused crashes during exits
  • Fixed rootcounter "generate single interrupt" mode. Fixes Vagrant Story, etc
  • Added NEGCON support. Haven't tested
  • Modified iDCT to skip all zero AC terms
  • Minor translator speedup, it's roughly 10-15% faster. Still working on more optimizations, most are not enabled due to stability issues, hopefully I'll be able to fix them when I free up some time
  • Added rudimentary PSF support, dunno if the timing is correct and minipsfs are currently not supported. More stuff regarding psfs hopefully soon
  • Implemented correct retirement of mapped registers in the translator
  • Changed GPU DMA timings, to fix weird glitches in some demos
  • Fixed error on SLL/SRL/SRA translator conditions when shift = 0
  • Fixed incorrectly translated signed compares (const vs const) during conditional branching
  • Fixed various FF9 crashes (i.e. ending sequence)
  • Fixed bug on compressed images (bz/isz) decompression routine, previously undecompressable/unplayable images can be played/decompressed now
  • Fixed cdr core error handling routines when sectors are unreadable
  • Fixed cdr core "ReadS", so it does not do any retry
  • Added cache/read-ahead to internal ISO (binary) reader for faster access
