SkyEmu VS giibiiadvance

Skyemu has a Web version that's usable on Android. Other than that, I don't think there's any new one.

The autogenerated source code for web.skyemu.app is also open source, and located in the following branch https://github.com/skylersaleh/SkyEmu/tree/gh-pages

I just added a Arm/Intel universal build to the release. You can download it here: https://github.com/skylersaleh/SkyEmu/releases/download/v2/SkyEmu-v2-macOS-universal.dmg

It is possible to make web applications in C++. Here is a web-based Game Boy emulator done in C. But it's a hell of a lot harder than doing it in a language designed to make web applications.

Despite it being a new emulator, it features high accuracy and compatibility allowing it to play difficult to emulate games that established emulators like mGBA and VBA-M struggle with. On top of accurate emulation. SkyEmu supports the following major features:

SkyEMU, the GB/GBC/GBA emulator project that I have been working on for the last six months was recently able to 100% pass all 1920 of Endrift's GBA suites timing tests. I believe this is the first time this level of timing accurate emulation of the GBA has been achieved and I wanted to share my excitement with the community.

Does anyone know of good documentation beyond: - Pan Docs - The Cycle-Accurate Game Boy Docs - Complete Technical Reference - Nitty Gritty Gameboy Cycle Timing

For actual documentation, you probably know the pandocs, but there are a lot of more specific information in the docs linked in their references, especially the cycle-accurate GB docs, the GB complete technical reference by Gekkio. You can also check the source code of the relevant test roms, like the Blargg’s test roms for more general behaviour and the MooneyeGB test suite for more specific things.
