Open keyboard mapping only with one-click, get the real PC like gaming experience by setting the controls on keyboard, mouse, or gamepad. Every feature is perfect for your gaming experience only. Supports keyboard, gamepad, script recording and multiple instances. The perfect Android emulator.It took me around week and half to get quite a few major titles perfectly (SMB, Super Contra, Shadow of the Ninja, etc). After reading nesdev wiki for a while I decided to give it a try mid-December 2017. The idea of writing yet another NES emulator is inspired from a medium post I read recently. The flexibility of emulators has given rise to some software that can be played on them.NesChan is a NES emulator I wrote just for fun. For example, for Mac users, not many games are available for the Mac OS, but with the use of an emulator, a lot many games can be played on Mac. For mobility, macOS has an on-screen keyboard suitable for direct selection with a mouse emulator and one designed for scanning with one or more adaptive.NESChan - a cross-platform NES emulator for Windows/Mac What is itAn emulator is used when the need arises to use particular hardware to play software meant for other hardware.Which platform is supportedCurrently Windows and Mac. As far as I can see Mesen is as good as it gets. There is something magical about seeing the little pixel sprites moving around in screens.I don't plan to create the greatest emulator ever. It is almost as exciting as writing my own game - except I don't have to write any games. It can convert BIN to ISO in order to burn BIN files with CD/DVD/Blu-ray.See Super Mario Bros and Super Contra in action:Just for fun - it's fun learning about NES hardware, how the games work, and getting my favorite game working.
Mappers - 0, 1 (partial), and 4 (partial - no scanline counting / IRQ support) It's not exactly right yet but pretty close. PPU - rendering pipeline with goal of cycle accuracy. CPU - all official and most unofficial instructions, with accurate cycle emulation (but it can't stop mid-instruction). What NES functionality is supported I haven't got around to try out linux yet but it should be relatively straight-forward given NesChan doesn't use any platform specific API nor libraries. Mac for dummies 2014Teenager Mutant Turtle 2 - freeze on start Super Mario Bros 2 - mario's eye is missing. Super Contra - first level boss fight background disappear. Mega Man 2 - vertical transition is somewhat glitchy. I've tested with my XBOX One controller.It's still in its early stage and only supports a few mappers (0, 1, a part of 3) so it only supports a small set of games. Supports keyboard and game controllers. Write Emulator Download SDL Development:)APU support - this one isn't too bad but I need to wrap my head around triangle waves, envelops, sweeps, delta modulations first.More mappers and more game support - Ninja Gaiden 2/3 and TMNT 2/3 are on top of my list (which I suspect are due to missing IRQ support in mapper 4).Add more test ROMs - it's way more effective to debug test ROMs than actual games! Not to mention they are good regression tests.Save/Load states - enough said. Under neschan repo, create a bin directoryIn the order of "most likely" to "probably never going to happen". Download SDL development libraries for Mac SDL2-2.0.7.dmg and unzip it into dep/sdl2 WinForms - Should work great on Windows +. Not sure about 2D rendering and controller support, though. Electron.js - Write a UI in JS as well as a JS library to interop with C/C++ neschanlib (using N-API). I'm not yet sure which UI library I'm going to use yet - but it's probably not going to be MFC in 2017, and it should be cross-platform. But I've no intention to draw my own UI like a real game in SDL. Imagine a NES Studio built on top of Eclipse / VSCode / VS - making translation/hacking ROMs/writing your own ROMs much easier.I'm planning to write a series of technical posts talking about my experience. Having one built-in would greatly speed up development.A development environment. It's extremely valuable to be able to see that glitching tile is index 0x80 and in address 0x1010. I frequently use Mesen's fantastic debugger to debug games to understand their behavior, viewing PPU memory/tiles/sprites and compare differences.
