  1. i got mine modded like 3 months ago and it is awesome to play imports. However the boot up animation isn't as great as the original imo

  2. Nice overview of the BIOS mod, been thinking about getting this done to my DC for a while now. Are you still happy with it? And how are you able to switch between the OG and dev boot screen?

  3. So I just wanted to thank you for your video on the Dreamcast BIOS upgrade, I followed your advice and picked up another Dreamcast and sent it to the eBay Guy who does the upgrade, still waiting on the package but soon thanks to you I will have a region free Dreamcast. thanks again a fan
