HyperFlash32 eInk Flash Cart

HyperFlash32 eInk Flash Cartridge for Nintendo Virtual Boy.  
 
5/29/2024 Update:  Batch 7 is done.  That's the end of HF32 builds and deliveries.  
 
HyperFlash32 is a single ROM Virtual Boy flash cart with 32 Mbit of built in flash memory along with an 8k x 8 nvSRAM that doesn’t require a backup battery. It can be reflashed from ROMs available on the microSD card without a computer connected. As such, it crosses the boundary somewhat between a single ROM cart and a multi-ROM cart. Although only one game is loaded at a time, it takes anywhere from 15 seconds to 90 seconds to load a new one. The digital labels and loading bar icons are user customizable. SRAM contents with save data are saved off to the microSD card and reloaded as ROMs are swapped out. You can even access your SRAM files to transfer to another HF32, or even to original VB game cartridges. HF32 has built-in capacitive touch buttons on the back to provide a fully self-contained user interface that doesn’t require a computer or GUI. It even has a haptic module to improve feedback on the rear capactivie touch buttons.
