[MULTI] Mednafen 0.9.33.2
Skomentuj

Mednafen jest bardzo udanym multiemulatorem, który powstał przede wszystkim z myślą o linuksie, jednak dzięki portowi pod win32 i ostatnio testowanej wersji x64, możemy pobawić się nim także pod okienkami. Jest na tyle dobrym udawaczem, że na podwalinie jego kodu powstały takie emulatory jak VBjin (VirtualBoy) i PCEjin (PCEngine) Delikata.

Już emulowane platformy to Atari Lynx, GameBoy (Color), GameBoy Advance, NES, PC Engine(TurboGrafx 16), SuperGrafx, Neo Geo Pocket (Color), PC-FX i  WonderSwan (Color)) i PSX,

Mednafen -- 0.9.33.2: -- March 24, 2014:

  • PSX: Fixed a small MDEC emulation bug; fixes the hang during startup in "SimCity 2000".
  • The order of evaluation of the frame advance and run normal command keys/hotkeys is now based on whether or not we're currently in frame advance mode, to allow for the derivation of a single-press pause/unpause key(effected by the user mapping both functions to a single key).
  • Renamed the log2 LUT array in the mpcdec code to avoid shadowing the math library function log2().
  • NES: Fixed the problem of the VS Unisystem DIP switch position display(accessed via the "F6" key) being invisible.
  • PCE: Fixed broken MCGenjin support.
  • CDPLAY: Tweaked visualization code to reduce memory and CPU usage.
  • Lynx: Minor code cleanups.

  • SS: Added kludge to fix layer offset problem in "Alien Trilogy".
  • SS: Added "WipEout" to internal database of games to use the data cache read bypass kludge with, to fix a hang that occurred when trying to exit gameplay back to the main menu.

Mednafen 1.21.2

This minor release updates Tremor to address a security vulnerability with Vorbis-encoded CD image audio tracks, and fixes graphical glitches in the Sega Saturn game "Shining Force III - Scenario 2".

April 2, 2018:

  • Updated bundled copy of Tremor to address a security vulnerability.
  • SS: Improved emulation of SCU DSP DMA to program RAM, per tests on a SS(still nowhere near perfect, the way it's implemented on hardware is kind of horrible, but it should work ok if games use it how it's meant to be used); fixes graphical glitches in "Shining Force III - Scenario 2", and perhaps in the other "Shining Force III" games as well.
  • SS: Flush the prefetched SCU DSP instruction when PC is set via PPAF, instead of when END/ENDI executes or when execution is forcibly stopped, per tests on a SS.
  • SS: Disallow SCU DSP LOP from being written in a looped single instruction unless it's the final iteration, per tests on a SS.
  • SS: Allow SCU DSP LOP to underflow to 0xFFF with LPS and BTM, per tests on a SS.

January 14, 2017:

  • WonderSwan: Fixed off-by-1 bugs in window coordinate evaluation, per tip from trap15.
  • WonderSwan: Fixed copyright notice headers to not allow distribution under versions of the GPL other than version 2(an oversight from
  • back when the Cygne code was added to Mednafen).
  • WonderSwan: Applied sound and DMA emulation fixes from trap15; fixes rain sound effect in "Star Hearts". The changes did necessitate lowering
  • the overall WonderSwan sound emulation volume a bit to prevent excessive clipping, however.

January 12, 2017:

December 25, 2016:

  • Modified configure script to (hopefully) compile in the Saturn emulation module when building for PPC64 and AArch64 architectures(in addition to x86_64).

December 21, 2016:

  • Allow emulated digital button mappings to be used in AND mode(like command keys configured with SHIFT+F2) if the user manually
  • prefixes the "/&& " magic string to the mapping setting string in the configuration file. Can be useful with emulated switches and mode toggle buttons,

  • more user-friendly manner.
  • Rewrote round_up_pow2() in math_ops.h to use MDFN_log2, which in turn uses MDFN_lzcount*(), since the major CPUs that Mednafen is going
  • to run on should have dedicated instructions to (at least indirectly) count leading zeroes. Also changed the semantics to return 0 on overflow instead of 1.

December 20, 2016:

  • SS: Now use leading-zero counting function from math_ops.h in the VDP2 rendering code, instead of using inline assembly.
  • Reorganized the leading/trailing bit counting functions in math_ops.h, added 32-bit and 64-bit trailing-bit counting functions, and added faster
  • variants where passing a 0 results in an undefined result.

December 19, 2016:

  • Print out the game key used after a connection is established with netplay, when the game key is not empty.
  • SMS: Added settings "sms.slstart", "sms.slend", "sms.slstartp", and "sms.slendp".
  • Added some checks to help prevent a black screen when the scanlines effect is enabled via a <system>.scanlines setting and the effective Y scale is
  • too small(by forcing negative-value behavior in the case of interlaced video, or temporarily disabling the effect otherwise).

December 18, 2016:

  • PSX: The functionality controlled by the "psx.input.analog_mode_ct" setting no longer interferes with netplay.
  • PSX: Added "psx.input.analog_mode_ct.compare" setting to control the combination of buttons used when the functionality controlled by the
  • "psx.input.analog_mode_ct" setting is enabled.
  • Modified build system to use $(localedir) instead of $(datadir)/locale for LOCALEDIR define.
  • Updated miniLZO to version 2.09.

December 14, 2016:

  • SS: Added setting "ss.h_blend", default value of "0", that when set to "1" will enable a horizontal blend/blur filter(with a much noticeable effect on the
  • Saturn video modes with a higher horizontal resolution).

  • Sega Saturn: Run VDP1 vblank erase at end of vblank, so we know how much time we have and thus how many entries in the framebuffer we’ll be able to erase. Currently, the available time calculations are generous, allowing for a bit more erase than what’s possible on a Saturn, but we can tighten it up in the future once it’s fairly certain there aren’t any more event scheduling accuracy issues. Fixes FMV subtitle text in « Panzer Dragoon ».
  • Sega Saturn: Fixed a bug that caused VDP2 frames to be short by 1 to 3 CPU cycles.
  • Sega Saturn: Reschedule the SH-2 DMA event handler as necessary to prevent it from running when the SH-2 bus is locked.
  • Sega Saturn: Force the SH-2 DMA and SCU DMA event handlers to be rescheduled to SH7095_mem_timestamp time when necessary.
  • Sega Saturn: Check for pending events right before calling VDP1, VDP2, SMPC, and SCU regs read/write handlers, which may then call their own event update functions.
  • Fixed an old bug that could cause a startup crash on Windows systems without XInput DLLs installed(e.g. some Windows XP systems).
  • NES: Fixed a very old bug triggered when disabling(via CTRL+1) the background layer, that would cause sprite pixels to also be visually disabled too under certain circumstances.
  • MD, PC-FX: Fixed several instances of left-shifting negative values.
  • Sega Saturn: Fixed a compilation error when compiling with the debugger disabled(« –disable-debugger » passed to configure).
  • Added configure options « –with-external-mpcdec » and « –with-external-tremor », for distribution packagers.
  • SS, SNES-Faust: Fixed a few issues causing compilation errors on clang.
  • Sega Saturn: Tweaked how seek command pause works; fixes a lockup issue in « Astal ».
  • WonderSwan: Fixed a bad usage of « char » without an unsigned/signed qualifier.
  • Sega Saturn: Slow down SCU DMA to VDP2 VRAM under certain conditions.
  • Sega Saturn: Adjusted VDP1 polygon and line draw commands to behave as if SPD=1, ECD=1 when color mode >= 6; fixes missing graphics problem in « Hi-Octane ».
  • Sega Saturn: Reworked SCU DMA’s timekeeping and scheduling code to be more accurate; reduces the size of the flickering section of the FMV in « Lunar ».
  • Sega Saturn: Fixed handling of CPU<->SMPC open bus.
  • Relaxed the CloneCD Q subchannel sanity checks to allow a track number of 0xAA(leadout).
  • Sega Saturn: Implemented kludgy(incomplete) support for quasi-illegal window X start position values; fixes ground layer issues in the forest stage of Panzer Dragoon 2.

Kolejna deweloperska wersja DeSmuMe - emulatora NINTENDO DS. Nie moja, bo z automatu AppVeyor, z którego zaczyna korzystać co raz większa ilość projektów, więc warto zapisać sobie bookmark. W DeSmume jak zwykle - troche zmian dla PC, ale gro dla portu Cocoa (MacOS).

Mednafen jest bardzo udanym multiemulatorem, który powstał przede wszystkim z myślą o linuksie, jednak dzięki portowi pod win32 i ostatnio testowanej wersji x64, możemy pobawić się nim także pod okienkami. Jest na tyle dobrym udawaczem, że na podwalinie jego kodu powstały takie ...

Ukazała się nowa, testowa wersja emulatora konsol NINTENDO (CGB,GB,GBA). Tym razem zmiany będą bardziej odczuwalne niż ostatnio, jednak to i tak kosmetyka - zmieniono podstawowy driver dźwięku na SDL (obecnie każdy inny powodował problemy z jego odtwarzaniem).
