A beautifully designed Sega Mega Drive 2 switchless multi region mod kit designed exclusively for the model 2 Mega Drive. It features a switchless multi region, controller functions for reset and region change, a dual frequency oscillator clock mod, Mega CD MultiBIOS compatibility, and pad placement conducive to perfect wire runs and a clean install. Hand made using the highest quality Panasonic resistors, Vishay capacitors, and genuine Microchip & Texas Instruments ICs.

Switchless Region Mod

The Mega Drive Model 2 Switchless Region Mod lets you set the region of the console to Europe, North America or Japan, essentially between PAL and NTSC regions. This is done by changing the Video Refresh Rate to 50Hz or 60Hz and the Language to English or Japanese.

When the mod is correctly installed, the console will run games in their correct aspect ratio and speed and bypass any region protection of imported games.

The reset button is used to cycle through the regions.

  • Setting 1 = Green LED – Europe/PAL – 50Hz/English
  • Setting 2 = Red LED – North America/NTSC – 60Hz/English
  • Setting 3 = Yellow LED – Japan/NTSC – 60Hz/Japanese

If you are running your PAL systems in 50Hz, you are really doing the games a great disservice. I consider these switchless mods necessary for PAL consoles.

*Note that this mod will require using the console’s native RGB output via an RGB Scart cable. 60Hz regions will be black and white via composite output. RGB is recommended over all other video outputs because of its superior video quality.

In-Game-Reset Mod

The Mega Drive In-Game-Reset mod allows the console to be reset or the console region to be changed from the controller.

Holding A+B+C+START for 1.5 seconds will reset the console. Holding this combination longer will cycle through the regions.

Design and concept by Consoles Unleashed.

After I designed and made the world’s first combined switchless region and in-game-reset mod for Sega Mega Drive 1 & 2 in 2019, I came up with the concept of combining a Mega Drive switchless region and igr mod with a Dual Frequency Oscillator in 2020. I then designed the first version aimed at Model 1 Mega Drive. This was the world’s first commercial Mega Drive Region/IGR and DFO mod kit. I then started work on other models such as a Model 2 only version and a simplified model 1 version. None of these mods were based on mods designed by others. There was nothing like these on the market or on forums at this time.

If you see these mods anywhere else, be sure that they copied my work.
