Yanese

Yet Another NES Emulator

Yanese is a free Nintendo Entertainment System Emulator for Windows XP,Vista, 7,8 and 10 under x86 and x64 processors.

The Emu won't be possible without this guy: Disch He helped me a lot in NesDev community. He also made a DirectSound C++ class that is used by my emu. Yanese uses: - The Disch DirectSound Class - Blargg's Blip Buf C Code     - SimpleIni for .INI files.     - Lame x86 and x64.DLL libraries	Version 0.89 x64 Unicode Version 0.89 x86 Unicode

09/21/15 - Version 0.89

• Scale2x: Scale2x is now available in normal mode. Before that it was available only in "Pixel Aspect Ratio".
• Blargg's Blip Buf: The emulator now uses Blargg's Blip Buf C Code for wave form generation Thanks to Blargg and Tepples for helping me.
• NTSC, PAL and Dendy mode: The was a bug that sometimes when you changed from PAL/Dendy to NTSC the emu de-sync the image. I think it's fixed.
• Mappers: Added mapper 226. I WON'T apply savestates for these two crappy games it runs. I only added it becouse i tought the games could be good. They are multicart pirated games that don't deserve savestates. Since the use the CPU address bus it's needed to be"specially" change code for them. But it's such a waste.
  

What it futures:

• NTSC, PAL, Dendy NES Emulation
• Scale2x in NORMAL MODE and obligatory on PPU "Pixel Aspect Ratio": This smooth pixels and shapes and is  the mode that lets "record videos"
• ROMS Library: Subdir /roms is scanned automatically if you add or delete roms.
• ROM PREVIEW: Disponible in window 2x and above. The emu will save the last image when you load a rom from the library and will show the BMP.
• GUI: Rom list navegable with the Keyboard and the Gamepad (if one is found) 
• Joypad GUI Navigation: If you have a Gamepad plugged. You can go "up" and "down" the roms list withe the Gampad. Pressing "Left" and "Right" is equivallent to Page Up and Down respectivly. Pressing the 4 NES buttons while playing will close the game and returns you to the library.
• Gamepads: Up to 2 gamepads for playing and one for navigating the "roms" library with autodetection, pluglabble and unpluggable capabilities.
• Video Recording: Record video of what you are playing in three differents qualities. *Only* avaiblable in "Pixel Aspect Ratio" Mode.
• Drag and Drop: Drag a .NES file to the window or to the .exe or shortcut and it will load the rom.
• Command Line: You can pass the path of the rom via command line
• Volume control: Popup window with "right click" to control volume or you can use "+" and "-" keys to control volume.
• Full Screen Wide or 4:3: "Alt + Enter" to toggle to fullscreen and back again. Fullscreen implies "Scale2x".
• Mappers: MAPPER 0, UNROM, CNROM, MMC1, MMC2, MMC3, MMC4, MMC5 (partial), AOROM,  BxROM, #11, #58, #64,#65,#66,#71, #91, #118, #189, #226.

Take into account that some functions are only available while the ROM is loaded. If not nothing will happen, for example volume control won't appear.

Default Emu Keyboard Keys are:

• Directions: Up, Down, Right, Left arrow.
• Buttons:
• B: Key "A"
• A: Key "S"
• Select: Key "Z"
• Start: Key "X"

This mapping can be changed in "input config" dialog.

GamePads:
They will be autodetected and set up.
Direction analog and digital is auto setup. Buttons can be changed via "Joypad Input Config" Dialog.
The gamepads are plugglable and unplugglable, that means you don't need to re-start or reconfigure the gamepads when you unplugg your gamepad.

Note: Yanese is currently under "Development". Expect some errors when you change from a version to another until a "Stable" version is commited.

Old Change Log:
09/04/15 - Version 0.85

• Unicode: The emu is entirely UNICODE now and calls its Win API. No more ANSI.
• Rom GUI: I have added a right click contextual menu to the "rom list". You can select: Load The Rom, Delete BMP preview and Delete ROM. Be aware that deleting a ROM deletes it permanently, it doesn't go to the Recycle Bin
  
• BMP Preview: When the emu inits it will check for orphans BMP roms previews and will delete it. I added this option if the emu thread is closedin a non-traditional way. So there are not unnecessary BMPs rounding in /rompreview.
• Rom Preview: The BMP preview is saved top to bottom inverted. If you explore the /rompreview folder you will see BMPs all inverted. Anyway the Emu shows it well in the Rom Preview window. I had to do this becouse i tested "LoadImage()" Win API in Windows 10 and it always failed. Thing that didn't happen in Windows 7 for example. This way ensures compatibilities between Windows Versions. Anyway i haven't tested it in XP, nor Vista neither Win 8. I think it should work fine.
• SCALE2X: The algorithm has been improved and consumes less CPU usage.
• INI File: The emu now uses SimpleIni class. It's encourged to delete the old .ini file you had.
  

08/17/15 - Version 0.81

• Rom UI: There were various problems with ROM GUI and they have been fixed.
• Window 1X: You can't use "Pixel Aspect Ratio" for this window size anymore. If you choose 1X from the menu or you resize the window that leaves it at this mode, "Dot by Dot" is automatically used.
  
• MMC3: Added support for Rad Racer II. Beware that this game uses 4-screen mirroring and there are some roms that doesn't report it well. The ROM i found reporting it well was "Rad Racer 2 (U) [b1].nes". You should get this rom if you want to play this game.
• VOLUME: It wasn't documented before, but you can use "+" and "-" keys to control emulator volume.
• SCALE2X: At window 4X in Pixel Aspect Ratio mode the emu does a Sacale2x over Scale2x. In other words it does it twice which consumes a alot of CPU resource, if the emu starts sounding bad or it's slow you should considere running in "Dot by Bot" 4X.
• Suspend More gone away: I have removed "Suspend Mode", so the emu will keep running if the window lost the focus, the best thing you can do is tu pause it.
  

08/14/15 - Version 0.80

• Rom UI: Now there is a "preview" window that shows the rom image preview. This is only available in window 2x and above. Everytime you close a rom the last image is captured and is used as the preview. Of course this works only if you load the rom from the "ROMS Library".
• NMI: Changed NMI behavior. Games like 1942 run well.
• APU: There was a problem in emulated sound that games like 1942 kept sounding. Fixed

07/15/15 - Version 0.79

• Mappers: Added mapper #65: Daiku no Gen San 2, Kaiketsu Yanchamaru and Spartan X 2 among others.
• Mappers: Added mapper #11: Crystal Mines, Metal Fighter, etc. Beware that this mapper has bus conflicts, so some games may behave bad or don't load at all.
• Mappers: Added mapper #64: Klax, Skull and Crossbones, Shinobi, etc.
• Mappers: Added mapper #71: The Fantastic Adventures of Dizzy, Bee 52. It doesn't work perfect by now, but at least works.
  
• Rom Library Gui: Small change taht it shows the mapper number for the unsupported mapper instead of "------".
• Fixed serious bugs in save states when saved to disk.
  

07/05/15 - Version 0.78

• Video: Fixed serious bug in PAL and DENDY mode that left games in that mode unplayable.
• Sound: Changed default 44Khz to 48Khz.

06/25/15 - Version 0.77

• Video: Added 4:3 aspect ratio support in full screen mode. You can change of common 3 resolution you want to be displayed. This is more likely playing in a real TV.
• App video crash: I tested the emu in some basic GPUs like Intel ones. It was sometimes crashing in this GPUs. I discovered that changing some compiler settings was the error.
• APU: Fixed Triangle Channel problem that some games didn't sound fine.
• SOUND: Added a "low pass filter" in sound generation. It sounds "better" not "too much better", but as i said a "little better".
• SOUND: Setting volume too high sometimes, in some games caused the sound to cut off.
  
• Improved some code.
  

05/24/15 - Version 0.76

• APU: There was an error in APU generating IRQs that didn't let to play some roms like "Alien III". It was fixed and now Blargg's "Clock Jitter" test pass.
• Memory Leaks: Fixed a seriuos bug that somethimes left memory leaks.
• Error while quitting: Sometimes when the emu was closed the app crashed. It's fixed.
• Improved some code.
  

05/16/15 - Version 0.75

• PAL: Now the emu supports PAL. Beware what rom you load when you set this mode. You don't have to load a (U) rom, you have to load a (E) rom.
• Dendy: Support for Dendy has been added. This are pirated NES (the one i had when i was kid).
• MMC3: Now MMC3 games run much better since its scanline counter is emulated more likely a real MMC3. Games such as Flinstones (and a couple more) al fully playable.
• MAPPERS: Added mappers: MMC4, #66 and #91 -> Street Fighter III and Mario and Sonic 2
• MAPPER: 1 - Fixed mapper #226: Now 76-in-1 runs fine. 2 - Fixed AOROM problem that chrashed the emu.
• SPRITES: Fixed an sprite fetch problem that crashed the emu.
• DMC: DMC now works better and sound better.
• SOUND: There was a problem in WinXP and Win 8 that the sound had glitches. This problem with DirectSound has been fixed. 
• Window Resize: The windows is now resizable and will match the closest "Windows X".
• CPU Usage: Lower CPU usage when the Emu is IDLE and is scanning the roms library.
• Joypad Detection: You can plug and unplug the gamepad when you are playing. If you unplug your gamepad then when it's plugged again the gamepad will be detected again.
  

04/21/15 - Version 0.70

• GUI: Rom GUI can now be navigated with the Gamepad: Up goes one rom up, Down goes go rom down, Left: Previous page in rom list, Right: Next page in rom list.
• GUI: Pressing the "A" gamepad button will load the rom, pressing all the NES buttons (B,A,Select,Start) close the rom and returns to the rom GUI when the rom is loaded.
• ROM Library: When you delete or add a rom/s to the "/roms" subdir is automatically reflected in the GUI.
• Sound: The emulator now is more playable and smoother than before becouse syncs pefect to 60hz.
  

02/05/15 - Version 0.64

• PPU: There is no more need of PPU hack to run games like "Battletoads". Now the PPU works more like a real one and those games doesn't hang.
• Mapper MMC3: Passed all tests except one. Since there are two revisions of this mapper this emu uses REV A and passes this one and not REV B.
• Apu Sweep Unit: It had a problem that games like "Batman" and "The Jetsons" sound bad. Fixed.
  

01/30/15 - Version 0.63

• FULL SCREEN: Windows Key is now disabled. Combinations "alt+tab" and "ctl+esc" put the emulator in windowed mode. This is done for Fullscreen issues, so the emu doesn'thang.
• APU: 1 - New Sweep Unit code. Games like "Excitebike" now listen well. 2 - Passed more Blargg's tests.
• Passed more Vblank/NMI Blargg's tests.

01/13/15 - Version 0.62

• Fixed a serious bug when opening Joystick Input Config Dialog

01/12/15 - Version 0.61

• OPEN FILE DIALOG BUG: There was a bug, that crashed the emu when OpenFileDialog() was called. Going deeper with this bug it seemed to be an OS internal error with directx. Fixed it.
• Do the "fixing" bug above now you could hear some distorded sound when you just open a ROM. I have to find a way around this.
  

01/11/15 - Version 0.60

• FULL SCREEN: Nice new future, you can switch to full screen and viceversa with "alt + enter". Fullscreen implies the use of Scale2x. Your current resolution will be detected and used as fullscreen. All functions are enabled (save states, pause/resume emu, except "ESC" (close rom)) although you won't see them printed to screen. Printing to screen would mean using D3D9ex and loose compatibility with XP. So you are blindly in this sense.
• AUDIO: Fixed the horrible scratched sound when just started loading a rom.
• VIDEO RECORDING: Lame bug that video outputed to 256x240 and now outputs correctly at 256x224.
• GAMEPAD INPUT: Now Yanese will write to the .ini file how you mapped joypads. I don't have 2 joypads to test it, but i think it's ok.
• MMC3: Fixed issues with this mapper wich made some games run bad. For example Ninja Gaiden 2 second level.
• Saved States and Screenshots filename: A minor change to format file name is saved wich now save a year like 01/08/15 and not 1-8-15. I think is more readeable this way.
  

01/06/15 - Version 0.53

• SOUND: Yeah i know im updating too fast, but this one is critical. There was audio sync problems causing sound glitchies. Fixed It.

01/05/15 - Version 0.52

• Video: NES Aspect Ratio was working bad becouse i wasn't appling linear interpolation. Now looks really good.
• CPU: Flags operation emulation changed.
• Video Recording: 1- Mp3 Quality -> poor: 64 CBR , normal: 96 CBR and high: 128 CBR 2 - There was a bug when the video was recording and closed yanese that left the video file unplayable. Fixed it.
• Save States: 1 - Since i changed the CPU internally flags operations previous save states format doesn't work with this version. Sorry. 2 - Fixed and issue when tried to load save state and the background on and off deffered from the save state file.
• Emu Info: I changed the emu emu info out (pause, suspend, etc) to look (i think) better. You can see it in the screenshots below.
  

01/02/15 - Version 0.51

• Save States: Save states works well now (i think).
• Sound: There was a problem with sound sync. I fixed it.

01/01/15 - Version 0.50

• NES Movie: You can now record a movie of what you are playing. The movie is recorded in AVI format with "Windows Video 1" codec for video and  MP3  for audio. You can also choose the quality. Recording is only allowed in "NES Aspect ratio" mode. Beware that movies consumes a lot of disk space.
• To do: There is a problem with save states and games that doesn't have VROM in the cart. This games (like Battletoads) when you save the state and then you load the state, the graphics looks scratched. I have to fix the issue.
• Minor bug fixes: Fixed some APU problems.
• Happy New Year!!
