HyperBoy+ vs MrCART: Which Virtual Boy Flashcart to Buy

Compare the HyperBoy+ 32Mbit Flashcart and MrCART Virtual Boy Multi FlashCart to decide which Virtual Boy flash cartridge fits how you load and play games.
Quick answer
Choose the MrCART Virtual Boy Multi FlashCart if you want to pick games from an on-screen menu without a PC nearby. Choose the HyperBoy+ 32Mbit Flashcart if you prefer loading files over USB and want a BWRY eInk panel in a full aluminum shell.
The real difference is how you choose a game
Both carts play Virtual Boy ROMs, but they approach the moment of selection differently. The MrCART puts game choice on the Virtual Boy itself with on-screen selection. The HyperBoy+ expects you to upload graphics over USB like game files, so your library lives on a computer until you transfer it.
That difference shapes your routine. If your Virtual Boy sits in a living room and your PC is in another room, an on-screen menu removes a trip. If you already keep ROMs organized on a laptop and do not mind connecting a cable, USB loading is familiar and direct.
What the HyperBoy+ shell and display change
The HyperBoy+ uses a BWRY eInk panel and a full aluminum shell. Those are physical choices, not gameplay features. The aluminum shell may appeal if you want a sturdier-feeling cart, while the eInk panel gives you a low-power display for status rather than a color screen.
The HyperBoy+ is based on Retro Onyx's HF32 design but is positioned as a cheaper way to get a Virtual Boy flash cart. It blurs the line between HyperFlash32 and HyperBoy. If you already know you want the HF32 lineage in a simpler package, the HyperBoy+ is the closer fit.
Homebrew and multicart expectations
The MrCART is described as the world's first Virtual Boy multicart with on-screen game selection, built by RetroOnyx with permission from Mr. Flower. That matters for a virtual boy homebrew flashcart library: you can keep several games on one cart and choose among them on the console.
The HyperBoy+ is a 32Mbit flashcart, and its catalog entry does not list a capacity for the number of games or an on-screen menu. Treat that absence as a decision limitation: if menu-free, multi-game browsing on the Virtual Boy is your priority, the MrCART is the clearer choice.
Decision rules for your Virtual Boy setup
- If you want to pick games on the console: Choose the MrCART Virtual Boy Multi FlashCart when on-screen game selection is the feature you will use most. It keeps the choice on the Virtual Boy rather than on a PC. Check that your play space is away from your computer; that is where the on-screen menu pays off.
- If you already load ROMs over USB: Choose the HyperBoy+ 32Mbit Flashcart if you are comfortable uploading game files over USB and want a BWRY eInk panel in a full aluminum shell. Confirm you have a USB cable and a computer near enough to your Virtual Boy for transfers.
- If you are building a homebrew library: For a virtual boy homebrew flashcart collection you want to browse on the console, favor the MrCART. If you prefer to manage files on a computer and transfer as needed, the HyperBoy+ fits that habit. List the homebrew titles you plan to keep on the cart before deciding how you want to select them.
