RetroArch 1.9.13

 多平台多機種模擬器 RetroArch 發布新版，更新如下 :

• CHEEVOS/MSVC2010: Add Cheevos support
• CRT/SWITCHRES: Fixes some issue where scaling is incorrect in some video modes for CRT output.
• FRAMEDELAY: Add ‘Automatic Frame Delay’ option
• INPUT: Add ‘All users control the menu’ setting – any gamepad can control the menu when this is enabled. Only limitation right now is that only player 1 can toggle the menu, but any set Menu Toggle Controller Combo will work fine for all users, so this should be acceptable for now

• NETPLAY/CLI: -C/–connect commandline fix
• NETPLAY: Other improvements
• NETPLAY: Remove forced disconnection on unknown netplay command – will be backwards compatible with any version that removed this disconnect. instead of disconnecting, we just read the data and ignore, like most network implementations do
• TASKS/CHEEVOS: Replace coroutines with tasks/thread
• TASKS/DATABASE/EXPLORE: Initialise ‘Explore’ menu on a background thread – no more stall when hovering over the Explore tab

DOSBox-X 0.83.19 (2021-11-01)

 DOS模擬器 DOSBox-X 發布新版，更新如下 :

• Reorganized the "List network interfaces" and "List
  printer devices" dialogs (under the "Help" menu) to
  allow the use of scroll bars. (Wengier)
• Added menu option "Reset TTF color scheme" to reset
  the current color scheme for TTF output. (Wengier)
• Added config option "righttoleft" in [TTF] section
  which when set to "true" will cause DOSBox-X to
  display text from right to left (instead of left to
  right) for the TTF output. It can also be toggled
  from the menu ("Video" => "TTF options" => "Display
  text from right to left"). (Wengier)
• Added config option "vga fill active memory" which
  when set to "true" will fill inactive video memory
  regions with RAM rather than mapping them as empty.
  This allows the ETen Chinese DOS system (倚天中文系統)
  3.5/2000 (e.g. ET16V and ET24VA) to run. (Wengier)
• Added config option "middle_unlock" ([sdl] section)
  to control whether to unlock the mouse with middle
  mouse button click. (Wengier)
• Added config option "dosvfunc" in [ttf] section to
  support DOS/V applications when country information
  is set to Japan in TTF output. (nanshiki)
• Added "VTEXT" command to view or change the current
  V-text mode for the DOS/V emulation. Also improved
  the font support for 24-pixel font DOS/V mode, such
  as supporting HZK24? fonts for Simplified Chinese
  DOS/V mode and STDFONT.24 from ETen Chinese system
  for Traditional Chinese DOS/V mode. If a Chinese
  font is specified via "fontxdbcs", "fontxdbcs14" or
  "fontxdbcs24" options, it will be loaded before
  system font even with "getsysfont=true". (Wengier)
• Commands like 80x25, 80x43, ... now use internal
  function for better compatibility with the TrueType
  font (TTF) output. (Wengier)
• MODE command without a parameter will now print the
  current lines/columns instead of usage. (Wengier)
• INTVEC debugger command now correctly outputs
  addresses when in protected mode. (Allofich)
• Fix horizontal lines in the debugger window being
  rendered as unrelated characters in some code
  pages. (Allofich)
• INT 21 AX=4B03 now sets AX to 0000 like MS-DOS
  does. Fixes missing music in "聊齋誌異之幽谷傳奇"
  (Liáozhāi zhì yì zhī yōugǔ chuánqí) (Allofich)
• Use 0x1E to 0x3E for the keyboard buffer of the CGA
  machine, which fixes the controls locking up in the
  PC booter version of Apple Panic. (Allofich)
• Allowed machine types "pcjr_composite" and
  "pcjr_composite2", similar to "cga_composite" and
  "cga_composite2", instead of having to switch the
  composite type manually. (Wengier)
• If machine is PCjr, place PC BIOS reset code at
  F000:0043 to match that of the real BIOS.
• Fix PCjr NMI handler to load DS with segment 0x0040.
  Fixes crashes in SHAMUS. (Allofich)
• Fix PCjr NMI handler to use 8086-level instructions
  when loading DS with segment 0x0040 so that it
  works properly with cputype=8086.
• Remove useless check for signed divide quotient
  of 0x80/0x8000/etc. (the result was -0x80/0x8000/etc
  anyway. Add code to check specifically for these
  values after signed divide if cputype=8086 and
  trigger divide overflow exception, to match behavior
  described for the 8086 processor.
• Modify exception handling so that for cputype=8086
  the return address for an exception handler points
  at instruction after fault location.
• Fix IDIV instruction incorrectly raising a divide
  error exception for some borderline values. Fixes
  Microsoft Flight Simulator. (Allofich)
• IBM PC BIOS emulation fixed to place key pieces of
  code and entry points at fixed legacy locations
  required by some older DOS games, instead of
  by dynamic allocation. Added code to BIOS allocation
  to reserve F000:E000 or higher for fixed allocation
  and force dynamic allocation below that address to
  prevent further conflicts should others submit
  pull requests for additional fixed locations. This
  fixes some games like "聊齋誌異之幽谷傳奇" (Liáozhāi
  zhì yì zhī yōugǔ chuánqí) which appear to assume
  some of these fixed BIOS addresses and will
  crash if they are wrong.
• Added tool EMSMAGIC.COM as alternative EMS manager,
  which can be dynamically installed or uninstalled
  with the setting ems=false. (Wengier)
• If a program is provided in the command-line when
  launching DOSBox-X, it will now be executed after
  any commands in the [autoexec] section by default.
  A command-line option "-prerun" is added to force
  the program run before any commands in [autoexec]
  section like before. (Wengier)
• Added auto-detection for single-wide DBCS-encoded
  characters for the TTF output (non-PC98). (Wengier)
• Improved the menu option "Restart DOSBox-X with
  language file..." (under "Main") for switching
  between DBCS languages. (Wengier)
• Disabled the Alt+F4 key for closing the DOSBox-X
  window in MinGW SDL2 builds. (Wengier)
• Fixed program or config file containing Unicode
  characters passed from command-line when launching
  DOSBox-X in Windows SDL2 builds. (Wengier)
• Fixed issue with DELETE key in PC-98 mode. (Wengier)
• Fixed COLORS config option (in [ttf] section) not
  working in the previous version. (Wengier)
• Fixed issues after resetting the virtual machine
  when using DBCS language files. (Wengier)
• Fixed some issues related to system IME support for
  CJK (Chinese/Japanese/Korean) languages, for both
  Windows SDL1 and SDL2 builds. (nanshiki & Wengier)
• Fixed bugs in the region memory allocator C++ class
  that claimed the entire free block even if the
  size wanted was smaller. Added field to remember if
  the allocated block was allocated for fixed or
  dynamically allocated memory. Cleaned up allocator
  code and removed redundancy.
• Fix SELINFO command not showing output correctly
  in the debugger window. (Allofich)
• Better CMOS register B and C emulation. (Allofich)
• Integrated commits from mainline (Allofich)
  • Support for DMF floppy disk images.
  • Zero-out DX in EXEC overlay command.
  • Improve stack check for wrap-around cases.
  • Change to misc_output for SVGA_S3Trio.

Xebra (2021-10-31)

 PS模擬器 Xebra 發布新版，更新如下 :

・ハードウェアレジスタ領域のバスエラーを正確にした。

ハードウェアレジスタがマッピングされているアドレス範囲は、1F801000から

1F802080なのだが、全てが埋まっているわけではなく、隙間があり、この隙間は

本来アクセスするとバスエラーが発生する。またワードアクセスでハーフワード

2つに同時アクセスが可能な箇所もある。これまでは、こういった市販ゲーム

ではやらないアクセスに対し何もしなかった(ロードでは0を返していた)のだが、

追加の詳細処理を用意した。

市販ゲームでアクセスしないのは、全く時短にならないからだと思うが、市販

ゲームでもアクセスするのに実装していなかったものがあったのでついでに実装

した。それはSPUにおける各チャネルの現在音量なのだが、そもそも、ここを使う

ゲームは少数で、用途としてはフェードアウトの完了確認くらいしかなく、0を

返しておけば問題にならないため省略し、いつの間にか存在そのものを

忘れていた。

・PALモードの1フレーム(フィールド)当りの時間を変更した。

これまでは、SCPH7000での測定値を採用していたが、平均的なPALマシンとの

差が結構あるといった声が聞こえてきたので、DTLH3000での測定値に変更した。

これまで採用しなかったのは、所有のDTLH3000では経時変化が大きく、

0.1クロックの精度もないことを嫌ったからだが、NTSCモードにおいても

型番により10数クロック程度の差があり、こだわっても仕方がないと考えを

改めた。ちなみに、約1%増加したので、FPSに直すと非インターレースモードで

50.22であったものが49.76に減っている。

検証動画で時間比較を行っているものがあるが、実機ですら型番でFPSが違う

という認識が欠けている。実機と比較するなら、型番の離れた2台を用意すべき

だろう。

・PIO, OS ROM の実行時間およびロード時間を修正した。

検証のために作成したプログラムが、どうやらキャッシュミスを発生させていた

ようで、その分、多めに評価していた。
