Kevin Mellott, creator of devices like the HyperFlash32 and the Dreamcast link cable has just listed all of his products on a new web store: https://www.retroonyx.com/products
Previously, you’d need to email Kevin directly for purchases, which isn’t the most efficient for anyone. At first, I imagine it wasn’t too bad, as some of Kevin’s items are a bit niche and hand-built, meaning there often weren’t enough to carry a full stock of them. Now that Kevin’s starting to produce higher quantities, a webstore is absolutely a must!
Anyway, check the link above to see what weird and wonderful products he’s selling for the Virtual Boy, Dreamcast, Wonderswan and others! Also, check out the videos below to see some of those products in action!
