Nintendulator, emulator Nintendo 8, został zaktualizowany i prawie jak zwykle pozostaje nam zerknąć w zapiski repozytorium żeby zobaczyć, co quietust dodał nowego do swojej aplikacji. Jak zwykle autor publikuje dwie wersje swojego emulatora - ANSi dla posiadaczy.... Win9X i unicode - dla wszystkich, z wyższymi wersjami systemu.
![[NES] Nintendulator v0.975 Unstable (27/05/2017)](www/picphoto/e409553d1.jpg)
Nintendulator v0.975 Beta (last updated 2017-05-27 9:56:59)
- May 27, 2017: Performing a reset or savestate save/load while emulation is active will no longer interrupt audio playback or controller input.
Revision 1343
Author: quietust | Date: 27 maja 2017 17:56:29
- Rework emulation start/stop logic for reset and savestates
- Add "soft" flag which does not interrupt audio playback
- Add "wait" flag which waits until scanline 240 (for savestates)
- Add "break" flag to handle old DoStop=2 logic
- Add Pause/Resume functions which perform a Soft Stop and do not unacquire controllers
- Add WaitVBlank function which runs to scanline 240 within the emulation thread (instead of the UI thread)
- Change soft reset, hard reset, save state, and load state to use Pause/Resume as appropriate
Revision 1342
Author: quietust | Date: 27 maja 2017 05:57:23
- * restore display resolution when leaving fullscreen
- * try to restore surfaces if they are lost, may reduce some error conditions
Revision 1341
Author: quietust | Date: 27 maja 2017 05:13:34
- Adjust error message
Revision 1340
Author: quietust | Date: 27 maja 2017 05:09:28
- Minor optimization for fullscreen - only "test" different aspect ratios once, and remember which ones failed
Revision 1339
Author: quietust | Date: 14 maja 2017 03:47:49
- Correct implementation for Mapper 96

Changelog:
February 20, 2024
- Today's build attempts to fix a hang that can happen when rapidly single-stepping through code with the debugger open, particularly when large numbers of PPU updates are taking place (e.g. with the MMC5's graphics extensions). Additional performance optimizations have also been made to the PPU debugger.
January 7, 2024
- The NTSC palette generator has been updated with properly measured voltage levels. Normal colors are largely unchanged, but color emphasis is somewhat lighter than before.
June 2, 2023
- Basic support for iNES Mapper 30 (UNROM 512) has been added; note that this does not include the ability to overwrite Flash ROM contents. Additionally, all mappers which emulate Bus Conflicts now do so in a deterministic manner.
Changelog from code
Jun 1, 2024
- Adjust Dripgame mapper sound output: Do pulse-width modulation instead of multiplying by volume - the result is pretty much indistinguishable, and it's closer to how this mapper might be hypothetically implemented on a real cartridge.
Feb 20, 2024
- Fix hang when rapid single-stepping with debugger
Especially with expensive mappers like the MMC5, it could occasionally get stuck in an infinite loop of processing WM_PAINT messages. Also add a missing include so it builds properly in MSVC 2022.
May 29, 2023

April 26, 2023

January 29, 2023
- Today's build fixes a bug in Wine 6.0 and later with certain window managers, where the main window shrinks to minimum size and jumps to the upper-left corner of the screen on program startup (as well as when the size multiplier is changed).
- Not coincidentally, this is also the first build of Nintendulator produced within Wine (using Visual C++ 2010).
January 11, 2023
- An error in the Debugger has been corrected so that accesses to the Stack now properly trigger memory read/write breakpoints.
November 12. 2022
- nw (see last revision)
December 4. 2022
- (iNES) Restrict mapper 66 to $8000-$FFFF. Jaleco games which used $6000-$7FFF were reassigned to mapper 140.
August 23. 2022
Robocop 3 (1993, Ocean)
- The NTSC palette generator has undergone a significant improvement and simplification - the standard palette should be mostly unchanged, but color emphasis should be much more accurate now.
commit 8ed2932111ed16dee593775f993d1dee22da3727 / 8ed2932
Author: Quietust <quietust@gmail.com>
Date: Sun Jan 7 08:42:57 2024 -0600
Update NTSC palette generator with proper voltages

- Turns out it doesn't like emplace_back() without parameters.
Revision 890
Author: quietust | Date: wtorek, 23 sierpnia 2022 04:15:19
- Adjust NTSC palette phase tables
- This way, "correct" colors are obtained by providing a phase adjustment of 0 instead of 3.
Revision 889
Author: quietust | Date: poniedziałek, 22 sierpnia 2022 21:43:35
- Partially rewrite NTSC Palette generator
- Get rid of the monstrosity that was the getPhase() function, and replace it with proper code for calculating YIQ based on information on the NESdev wiki. Note that this still uses the old YIQ coefficients and does not perform gamma correction, so the "standard" palette should look the same as before; however, the Emphasis palettes are now noticeably different (and arguably a lot closer to what they should be).
Revision 888
Author: quietust | Date: sobota, 13 sierpnia 2022 02:10:47
- Rewrite Breakpoint management code to be less ugly * Instead of using a handmade linked list, use std::vector
- Instead of sorting breakpoints, add buttons for reordering them
- When deleting breakpoints, select the next one in the list
Revision 887
Author: quietust | Date: wtorek, 9 sierpnia 2022 21:22:48
- Fix controller config code to avoid crash
- If the registry contains an invalid controller ID, display an error but
- then reconnect the "unconnected" controller, otherwise it'll crash.
July 18, 2022
- Prompted by an online discussion about optimization, I made a minor optimization to the PPU's FrameSkip rendering code and a major optimization to the APU code when sound is disabled, allowing "fast-forward" to run much more quickly than before
Revision 886
Author: quietust | Date: poniedziałek, 18 lipca 2022 22:26:23
- Optimize sprite 0 hit during frameskip
- There's no need to keep the 2 pattern bits separate - OR them together, and you can just AND the resulting pixels together.
- Also move the Sleep() inside the APU code so it doesn't happen when audio is turned off, increasing fast-forward speed significantly.
Revision 885
Author: quietust | Date: poniedziałek, 11 lipca 2022 05:44:54
Update savestate logic
- Print error message if block length during load doesn't match

June 9, 2021
- The debugger now permits setting breakpoints at the beginning of any scanline. The pre-render scanline is specified as -1 (as the Debugger normally displays it), but you can also specify scanline 261 for NTSC or 311 for PAL and it will translate it accordingly.
May 28, 2021
- Partial NES 2.0 support has been added to iNES mapper #4, allowing it to emulate the MMC6 when submapper 1 is specified.
May 24, 2021
- When I did the "infrastructure update" to the mapper DLLs two months ago, it turns out I introduced a typo in UNIF support which caused all "HVC-*", "UNL-*", and "BTL-*" boards to incorrectly load as "NES-AMROM". This has now been fixed.
March 27, 2021
Mapper 218 (a "single-chip" cartridge containing only PRG ROM and using the nametable RAM to hold graphical tiles) is now supported.
I've also added project files for Microsoft Visual C++ 2015 (better late than never), and in the process I discovered that a few obscure multicart mappers were broken due to name conflicts between global variables and function parameters (for which Visual C++ 2010 did not emit warnings).
Also, I hear that copyright years are a thing that you actually need to update, so there's that too.

March 22, 2021
- Today's build fixes a small bug in the mapper interface which would have prevented the debugger from working when using Game Genie codes.
- It also features a massive update to the mapper DLLs to dramatically simplify the process of adding new mappers - each mapper definition now automatically adds itself to a globally defined list on startup. The primary upshot of this is that I no longer have to keep around a statically-defined list of every possible mapper number, so supporting higher NES 2.0 mappers is now much more straightforward (the old method would've required tripling the size of 3 different lists). The downside is that locating a supported mapper now requires performing a linear search, but even with 4096 different mappers that would still only take a microscopic fraction of a second.

[CGB] SameBoy 0.16.7 4/10/2024
SameBoy jest emulatorem sprzętu Nintendo GameBoy, ColorGameBoy i w przyszłości GBAdvance (być może i coś już odpala, nie trafiłem jednak na nic, co dałoby się uruchomić) napisanym z myślą o Macintoshu, jednak i nam blaszakowcom dostała się wersja (SDL), którą z powodzeniem można używać.
Ostatnie zmiany to praca nad SameBoy'em pod IOS'em

[multi] DSP 0.23 VIP4 29/09/2024
Emulator DSP sygnowany przez imć Leniada, pozwalaja na zabawę maszynkami arcade i ośmiobitowcami - CPC, ZX Spectrum (z bardzo fajnie rozwiązanym podglądem plików), a także Colecovision, Nintendo 8 i CGB/GB - wszystko, co ma Z80 na pokładzie jest mile widziane;)
Ostatnia pełna wersja tego DSP Emulator DSP 0.22 Final pojawiła się 19 listopada 2023 r.
Nintendulator is an open source Win32 NES emulator written in C++. The original goal was to emulate the NES down to its hardware quirks; though it's fallen behind over the years, recent builds have caught up once again and can emulate certain behaviors most other emulators neglect to handle. However, this emulation precision comes at a price - a 1500MHz (estimated) or faster CPU is required to emulate at full speed.
Supported file formats include .NES, UNIF, FDS (fwNES format), and NSF. Mappers are handled using external DLLs, complete with extra sound channels for most games which provide them. Other notable features include writing to FDS images (by storing the differences in separate files), Game Genie support (limited to 3 codes), customizeable controllers (including 4 player), input movie recording and playback (with re-recording), AVI capturing, and a debugger with moderate breakpoint support. Additionally, savestates and battery-backed RAM are saved within the current user's Application Data folder rather than in the application's own directory, allowing Nintendulator to function properly when not run as an administrator.
