The MegaSD is an all-in-one flash cart for the Sega Genesis / Megadrive that plays games from the Master System, Genesis, SegaCD, and 32X (with 32X hardware).
Firmware can be downloaded here (Current Firmware is 1.04 R09) Please note that you need to register your device and if firmware is not present after registering it means you are on the most current firmware already.
Manual is located here
Set-Up
- Any storage size MicroSD card should work as long as it is FAT32 or ExFAT formatted. TerraOnion generally recommends avoiding Samsung branded cards as they have been known to cause issues on their devices. Sandisk is the preferred manufacturer.
- CD games must be in their own folders. The folder name dictates the name that is displayed in the MegaaSD menu for CD games. Nested folders are fully supported for both CD and cartridge games.
- Sega CDX, X'eye, Wondermega, allow cartridge based games to load but CD games are disabled due to potential bus conflicts that could damage your original hardware.
- If you have a SegaCD/MegaCD attached while using a MegaSD CD games are disabled.
- Similarly CD games cannot run through a 32X. Using a MSDEXP can bypass this limitation.
Usage
- Various hardware configurations can offer differing experiences. Please refer to our MegaSD Compatibility page.
- Seek time emulation allows games to run at a simulation of the speed of an actual disc. If you have problems with a particular game try toggling it on and off. In most instances leaving it on works best. Also let the TerraOnion team know of your findings.
Game Compatibility & Known Issues
- In-Game Menu and Save States do not work on Master System...yet
Tips & Tricks
- MegaSD can use cfg files to alter the loading parameters for games. Details can be found on the Config File page.
