Der Multi-System Emulator Mednafen für MacOS, Linux und Windows wurde aktualisiert.

Mednafen a multi-system emulator has been updated.

This release fixes a PS1 GPU emulation timing regression introduced in 0.9.37 that causes "Tobal No.1", and possibly some other interlaced games that run at 60 fields per second, to be unplayable.
This release fixes a few minor bugs in 0.9.38-UNSTABLE, including broken PSF/PS1 EXE support.
This release drops support for reading directly from physical CDs for various technical, emulation quality, and maintainability reasons.

Notable end-user changes compared to
  • Dropped support for physical CDs.
  • Added support for per-game configuration override files.
  • Lynx: Added support for custom palettes.
  • PS1: Improved multitap emulation; DualShock rumble will now work with multitap in games that utilize multitap functionality(for example, "CTR - Crash Team Racing").
  • PS1: Improved CDC emulation; fixes lockup issues in "Wing Commander III", "CyberSled (Japan version)", "Pooh´s Party Game: In Search of the Treasure", "Harukanaru Toki no Naka de - Banjou Yuugi", and "This Is Football 2".
  • PS1: Brought MDEC decode timing closer to what it is on a PS1; fixes stuttering issue in the early FMV-background sequence in "Parasite Eve II".
  • added filesys.path_pgconfig
  • added osd.message_display_time
  • added srwautoenable (undocumented, do not use unless you´re a space goat)
    removed psx.clobbers_lament (deprecated/no-op in 0.9.37)
  • Fixed some issues causing compilation errors on gcc 4.7.x.
  • Conditionalize the compilation of shared hardware emulation components(such as 68K, Z80, YM2612, etc. emulators) based on what emulation modules are being compiled in, since support for loading external emulation modules never went anywhere, and if we do eventually add support for it, the exported symbols won´t include the common specific hardware emulation components.
  • Fixed some code causing compiler errors with clang 3.4.0.
  • Fixed broken loading of save states made with 0.9.37+ on big-endian platforms(0.9.37 regression).
  • fflush() before fstat() on the underlying file descriptor in FileStream::size() if the stream is open for writing.
  • Added zlib type-size sanity tests to tests.cpp
  • _LARGEFILE64_SOURCE and _LARGEFILE_SOURCE are now defined to "1" in config.h, for zlib purposes.
  • PSX: Avoid undefined behavior(that wasn´t currently causing any problems) in the CPU core.
  • PSX: Clamp final SPU output samples(before volume adjustment and resampling) properly; lack of it wasn´t causing any problems per-se, but it could have been an issue in the future.
  • GB: Load GBC custom palette from "gbc.pal", not "gb.pal"(0.9.37 regression).
  • NES: Fixed a minor issue that could break compiling after --disable-nls was passed to the configure script.
  • PSX: Fixed half-implemented broken implementation of CDC command 0x00; fixes lockups in the European PAL releases of "Spyro 2" and "Spyro - Year of the Dragon".
  • Added support for automatic loading and usage of redump.org "SBI" files when loading CUE sheets; the files should have the same base filename as the CUE sheet, and the file extension case should match the case of the corresponding character in the CUE sheet filename file extension.

    "Super Bandicoot Luigi (Moon, Niflheim, Australia).CuE" -> "Super Bandicoot Luigi (Moon, Niflheim, Australia).SbI"
  • fixed a piece of ancient mouse button mapping/reading code that was so broken it worked most of the time;
  • fixes broken mapping of more exotic(other than left, center, and right) physical mouse buttons to virtual buttons.
  • Lynx: Fixed a minor stereo sound emulation issue thanks to a patch from "sage".
  • Lynx: Fixed a bug that could cause Mednafen to crash when a game attempts to power-down the emulated Lynx(which may occur if a game is left unattended for a prolonged period of time).
  • WonderSwan, PC-FX, MD, NGP: Fixed several violations of C/C++ sequence point rules in relation to call order in expressions of functions with side effects, that could lead to undefined/wrong behavior with certain types of compiler optimizations and features(e.g. PC-FX emulation was broken on gcc 4.9.x with -fsanitize=undefined -std=gnu++11).
