Just released Red Viper, a Virtual Boy emulator that runs on the Nintendo 3DS. All official games run at full speed! github.com/skyfloogle/red-vi…
Red Viper v1.3.0 introduces a new rendering system that downloads the image rendered by the 3DS GPU into the Virtual Boy's GPU. With this, Test Chamber works correctly at full speed, even on the original 3DS! github.com/skyfloogle/red-vi…
Red Viper v1.2.0 introduces local wireless multiplayer! Compatible with games including the Mario's Tennis multiplayer patch, Hyper Fighting, and on New 3DS, the recently released Virtual League Baseball 2! github.com/skyfloogle/red-vi…
Since today's still the 30th American Virtual Boy release anniversary in some parts of the world, I'm releasing Red Viper v1.1.0, featuring a software renderer to improve compatibility with PizzaRollsRoyce's incredible Test Chamber homebrew on the New 3DS! github.com/skyfloogle/red-vi…
Test Chamber is available at platonicreactor.com/projects…

Marking the Virtual Boy's 30th anniversary, I'm releasing Red Viper v1.0.0, featuring more advanced palette configuration and Circle Pad Pro support! github.com/skyfloogle/red-vi…
Got lots of "is x in range" checks in your performance-sensitive code? Here's a micro-optimization for you:
// 2 branches
slow = pos >= start && pos < end;
// 1 branch
fast = unsigned(pos - start) < size;
I couldn't find an easily accessible tool to make animated banners for the 3DS Home Menu, so I spent an embarrassing amount of time my own. Check it out: github.com/skyfloogle/pycgfx
Red Viper v0.9.8 features timing improvements, allowing games to play their audio at the correct speed! github.com/skyfloogle/red-vi…
Red Viper v0.9.7 features a new anaglyph colour filter for 2DS users, and accurate render time emulation! github.com/skyfloogle/red-vi…
The video below demonstrates the difference in Golf's level select.
For more info on the render time emulation (it took me a long time to figure out!) check out my write-up: skyfloogle.github.io/vip-tim…

The new 0.4.0 version of VUEngine Studio adds a second built-in emulator config that allows you to wirelessly send ROMs to a Nintendo 3DS running @Skyfloogle's Red Viper emu for quick testing. vuengine.dev github.com/skyfloogle/red-vi… #VirtualBoy #homebrew #VUEngine #3DS
Red Viper v0.9.6 features an antiflicker mode to mitigate image retention issues on IPS models, and an optional input display for speedrunners! github.com/skyfloogle/red-vi…
Red Viper v0.9.5 features fully customizable controls, including toggle and turbo settings! github.com/skyfloogle/red-vi…
i recently received confirmation that red viper has had circle pad pro support this entire time
i had no idea, despite being the creator
apparently support for it is built into the OS, and it's accessed the same way as the n3ds's additional controls for backwards compatibility
Red Viper v0.9.4 introduces savestates, with 10 slots per game! github.com/skyfloogle/red-vi…
