Sega Genesis/ Sega Mega CD/ Mega CD 2/ Wondermega BIOS Collection ROM Description

Hello everyone, this post is for those who are looking for original BIOS files for Sega Genesis/ Sega Mega CD/ Mega CD 2/ Wondermega emulators. We have compiled all BIOS versions that were ever released on the original systems. You can use them on any Sega Genesis emulator.

Note that the BIOS is always the backbone of any emulator and it is required if you want to play emulated games. In fact, most Sega Genesis/ Sega Mega CD emulators today have the original BIOS built-in, so you don’t need to install it manually. However, there are some exceptions where we think you will need it:

• Some older emulators have not updated to the latest BIOS version and you need to do it manually.
• Accessing special features: If you want to use some special features of the emulator, such as overclocking or using BIOS mods, then a separate BIOS is required.

Sega Genesis/ Sega Mega CD/ Mega CD 2/ Wondermega emulators are now quite popular so you can use them on most platforms such as Windows (with Kega Fusion, RetroArch), MacOS (Kega Fusion, RetroArch, OpenEmu), Linux (RetroArch), Android (RetroArch, ClassicBoy Pro, GENPlusDroid) and iOS (Provenance, RetroArch). Currently, Kega Fusion is highly recommended by the community because it has the ability to run the most accurate emulation with high stability and good performance. RetroArch is also a bright alternative thanks to its flexibility and cross-platform compatibility. Depending on your personal preferences, you can choose one that suits you. Anyway, this is an old classic gaming system that has been released for a long time, so emulating it is not difficult.

Note about BIOS version names

The letters “Rev A, B, C…” in the BIOS filenames of Sega Genesis (or Mega Drive) represent revisions of the hardware or software. Each revision usually includes improvements, bug fixes, or minor changes.
