Red Viper is a Virtual Boy emulator for the Nintendo 3DS, created by skyfloogle and continuing the work of mrdanielps with his r3Ddragon VB emulator. According to skyfloogle on his GitHub repo, Red Viper uses a dynamic recompiler with busywait detection and a hardware-accelerated renderer to achieve high performance on the 3DS’s limited hardware.
To use it, you’ll need a modded 3DS and then you can install it using Universal Updater or scan the QR code on FBI.
