My NES is a Nintendo Entertainment System / Family Computer (Nes/Famicom) emulator written in C#. My NES is meant to be simple, powerful and accurate Nes emulator.

iNES is a NES Emulator for Windows and Linux.

The NES emulator HalfNES has been updated.

A new version of the NES emulator Mesen has been released for Windows and Linux.

I have pushed iNES 5.1.3 for Android, a new version of my Nintendo Entertainment System (NES) and Famicom emulator, to the Google Play. This release adds the remaining time display during replay and makes Settings use the same textured backgrounds as the rest of the app. I have also switched Settings to the Material Design theme and fixed a bunch of replay issues found when adding time display. See below for all the changes.

• Added remaining time display during replay.


• Fixed replay rollover mechanism.


• Added shadow underneath the time display.


• Settings activity now uses black/white UI setting.


• Switched Settings to Material Design on Lollipop+.


• Stopping replay when emulation reset or state loaded.

I have just released iNES 5.1.1 for Android, a new version of my NES and Famicom emulator. This release fixes gamepads operation on ShieldTV and other AndroidTV devices. I am now skipping "virtual" input devices that do not represent real gamepads. I have also fixed the DropBox crash, which occurred when your app folder had subfolders, and moved to the latest Android SDK version. See below for all the changes.

• Fixed DropBox crash when app folder has subfolders.


• Fixed gamepad on Nvidia ShieldTV and other AndroidTV devices.


• Any input devices named as "virtual-*" are now ignored.


• Any virtual (android-16) and disabled (android-27) devices are ignored.


• Switched to the latest android-27 SDK.


• Now using Android build tools version 27.0.2.

The new iNES 5.1 for Windows and Linux is now available for free from the iNES home page. This release adds multiple monitors support on Windows, fixes disappearing windows, DirectInput, and flicker that appeared in Win10. The directional pads found on XBox gamepads should work in this version. The Linux version now uses PulseAudio sound, so that you do not have to mess with the OSS sound emulation. Finally, I am now treating all mapper #99 ROMs as VS-System ROMs. See below for all the changes.

• Made iNES treat all ROMs with mapper #99 as VS-System ROMs.


• Added multiple monitor support to iNES-Windows.


• Fixed disappearing window in iNES-Windows.


• Fixed best full-screen mode detection in iNES-Windows.


• Fixed window flicker that appeared after recent Win10 updates.


• Fixed default window position to the middle of the screen in iNES-Windows.


• Fixed DirectInput joysticks support in iNES-Windows.


• Made directional pads work on XBox gamepads.


• Switched iNES-Linux to using PulseAudio sound.


• Updated old PulseAudio driver for 64bit Linux.

Finally, the Android version of iNES is currently on sale for $2.99.

iNES 5.0.2 for Android, a new version of my Nintendo Entertainment System (NES) and Famicom emulator, is now online. In this version, I have taken measures to work around Android 7+ restrictions on system folders access. You should be able to navigate through restricted folders, even if you can't see their contents. If you do get stuck in such a folder though, use the new "Change Folder" option to jump where you need to go. I have also fixed a bunch of bugs reported by the Google Play console. See below for all the changes.

• Added "Change Folder" option to the File Selector for jumping between folders.


• Made folder listing error a bit less threatening, since it has become the new normal in Android 7+.


• Fixed hangup on exit where Java code waits for non-existent native thread.


• Removed outdated features from the EMULib code.

An updated iNES 5.0.1 for Android is currently rolling out to the Google Play Store. This release fixes a few crashes and addresses the awkward situation where a user navigates to the root folder of his device only to find out that he has no permission to list files there and nowhere to go. Such situation should no longer happen. It only affects newer Androids though. See below for all the changes.

• Fixed File Selector getting stuck at unreadable root folder.


• Fixed native crash when processing initial commands sent by Java side.


• Fixed crash when loading an invalid skin bitmap file.

I have released iNES 4.9 for Android this morning. This new release of my NES and Famicom emulator fixes a bunch of crashes reported by the new, more vigilant Google Play Console and improves compatibility with some misbehaving gamepads. See below for all the changes.

I have published iNES 4.8.9 for Android today, removing the need for the READ_PHONE_STATE permission. Many people complained about this permission, since it also allows the app to make phone calls (which iNES obviously does not need). In reality, this permission has only been used to obtain the unique IMEI number, used to identify your device in the logs when you need help. Starting with this release, I have switched to the AndroidID for device identification, removing the request for permission.

• No longer asking for READ_PHONE_STATE permission.


• Application will use AndroidID rather than IMEI to identify users.


• When emailing for support, attach your AndroidID (dial "*#*#8255#*#*").

A new version of the NES emulator Mesen has been released for Windows and Linux.

I have just published iNES 4.8.5 for Android, fixing a few things requested by users. Starting with this version, pressing analog triggers on your gamepad (such as Nvidia ShieldTV gamepad) will simulate L2/R2 shoulder buttons, rather than L1/R1. This way, you can assign these analog triggers separately from the regular L1/R1 shoulder buttons. I have also removed tiny text cues from the virtual gamepad skins which already have their own button labels.

An update of the Nintento NES and now also Sega Master System emulator nemulator has been released.

A new version of my NES and Famicom emulator, the iNES 4.9 for Windows and Linux, is now available for free. This release greatly improves DiskSystem sound chip emulation and fixes several issues with MIDI playback and recording. The Windows version also adds an option to disable Direct3D linear image interpolation. See below for all the changes.

• Added waveforms to DiskSystem sound chip emulation.


• Added volume envelopes to DiskSystem sound chip emulation.


• Computing effective waveform power when simulating samples via MIDI.


• Fixed triangle channel volume when playing via MIDI.


• Fixed "Hit MIDI Drums" option in iNES-Windows.


• Added "Nearest Neighbor" option to disable linear interpolation.


• DiskSystem disks now get loaded starting with side A.

A new version of 3DNES is out.

A new build from the NES emulator FCEUltra-Win32-mappers-modified has been released. This emulator is based on FCEUltra source code snapshot (fceu-0.98.13).

An update of the Nintento NES and now also Sega Master System emulator nemulator has been released.

iNES 4.5 is now freely available for Windows and Linux. This new release adds support for TKSROM/TLSROM boards (mapper #118) and various JY Company hardware (mappers #90, #209, #211). I have also corrected interrupt handling in mappers #17, #18, #168 and fixed I/O port reads for a few more hardware types.
