MegaCD 2 : region free bios install

Sat, 08 Jan 2022 18:43:38 +0000

The Mega CD (1 or 2) is region locked. Unlike the Megadrive, the region check is not done in hardware, but directly in the BIOS. It means that all MegaCD are (almost) identifcals but a different BIOS has been installed for each region (EUR / USA / JAP). There is basicaly two ways to get another BIOS : loading one from an everdrive or replacing the original BIOS by a region free one. I have at least one game that does not work with a BIOS loaded from an everdrive : “Soul Star”. Moreover, I find it more convenient to launch CD games directly. IMHO, the worst BIOS version is the EUR because it is locked at 50Hz. The JAP one is told to be “the best” because it is said to have some unique features / API needed for some JAP games, but I do not know any game in that case. So The best option seems to be the USA version with its english text menus.
