The board itself works great but some of the accessories that came with it don't fit. The heatsinks don't fit with the plastic cover it came with. I've left the heatsinks off but the machine runs beautifully otherwise. ## Frequently Bought Together - BITFUNX GDEMU V5.20b Optical Drive Simulation Board, Repair Part Optical Drive for Game Console VA1 Host, for SEGA Dreamcast DC VA1 Console SD Extension - Dreamcast Console Power Supply,12V Dreamcast Power Supply Replacement Kit,Internal Power Supply Adapter for Dreamcast Game Console --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hk/products/724501724-bitfunx-gdemu-v5-20b-optical-drive-simulation-board-for-sega](https://www.desertcart.hk/products/724501724-bitfunx-gdemu-v5-20b-optical-drive-simulation-board-for-sega) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-13*
