MegaDrive++ is a modchip for the Sega Mega Drive (AKA Genesis) with Region switching, 50/60 Hz toggling and In-Game-Reset (IGR) functionalities.
MegaDrive++ has the following features:
- EUR/USA/JAP mode switching: this effectively makes your console universal, allowing it to bypass region checks and to run all games without resorting to an adapter.
- If you come from a PAL region, you will also be able to run most games at 60 Hz, which means full-speed and full-screen! Get rid of those black bars! See the difference here!
- The mod is switchless, so you don't need to modify the aesthetics of your console installing ugly switches, but rather you will be able to change the region:
- Through the Reset button: Keep pushed to cycle through modes.
- From the Player 1 controller pad: Press Start + B + Down/Left/Right to set your desired mode.
- The last used mode is saved automatically after 5 seconds and reused at power up.
- Supports a single, dual or RGB LED to indicate the current mode.
- Reset-From-Pad (AKA In-Game-Reset AKA IGR): Press Start + A + B + C.
- Supports consoles with both active-high and active-low reset signals by autosensing (i.e.: all console revisions!).
- Uses a cheap Arduino Nano board.
- Uses the popular Arduino environment, allowing for easy development, testing and modifications.
- Even though default settings are recommended, everything can be customized to taste.
- Last but not least, it is Open Source and Free Software!
If you were a MegaDrive++ user before May 2019, please note that a few things have changed:
- The old 6button/lcd_support branch has become the master branch: this is now the recommended version to use and the only supported hardware is the Arduino Nano.
- The old master branch has become the legacy branch: this is only kept for reference, it is no longer supported and won't get any updates in the future.
See this for the rationale behind this change.
