Compatibility: Mega Sg

The MegaSD is compatible with Analogue's Mega Sg console, however there's currently compatibility issues with the Mega Sg and the Sega CD that will need to be fixed in a firmware update from Analogue. The majority of these issues should NOT affect the MegaSD when it's used through the cartridge port. If you're using the MSDEXP with the MegaSD on the Mega Sg, you will encounter these compatibility issues. In the current firmware (v4.7 from Analogue, v7.7 for the jailbreak) games like Sonic CD, Final Fight CD and others will not work correctly when running them through the expansion slot with both real Sega CD units and the MSDEXP with the MegaSD. You can workaround some of these compatibility issues by downgrading the Mega Sg's firmware to v4.6 (which is from Analogue) or v7.6 (for the jailbreak firmware) but games like Chuck Rock, The Adventures of Willy Beamish and NHL '94 won't work while running them through the expansion slot.

Again, the MegaSD when used through the cartridge slot will avoid most of these compatibility issues, except for games like Double Switch and the US release of WWF: Rage in the Cage which have issues that Analogue will need to fix in a firmware update. This is NOT a MegaSD issue.

Compatibility: Sega Nomad

The MegaSD is compatible with the Sega Nomad however there's a couple compatibility hurdles to keep in mind here.

  • Sega Master System game support requires a modification to the Nomad allowing them to work.
- Similarly the SG-1000 will NOT work at all on the Sega Nomad, as the Genesis VDP lacks the video modes required to display SG-1000 games correctly
  • The Sega Nomad cannot output CDDA audio from Sega CD games without a modification.
-The Nomad Triple Bypass from Mobius Strip Technologies is highly recommended to add CD audio support to the Sega Nomad

Compatibility: Sega 32X - Original Hardware

The MegaSD is able to load 32X ROMs, however this requires a real 32X. When using the MegaSD with original Genesis/Mega Drive hardware, there's a couple things to keep in mind here.

  • Make sure the Game load reset type option in the MegaSD is set to Hard.
  • You may or may not need to disable the Auto region fix option for the MegaSD if you have it set to On.
  • If your 32X is a launch version (revision VA0) you WILL need to either have the 32X bus terminator (AKA the 32X extension unit) attached to the expansion slot of your Genesis attached or have a real (powered) Sega CD attached to your Genesis. You can also use the MSDEXP from Mobius Strip Technologies as a bus terminator.

Compatibility: Sega 32X - Mega Sg

The MegaSD is able to load 32X ROMs, however this requires a real 32X. When using the MegaSD with Analogue's Mega Sg you also need the Analogue DAC and the Analogue DAC to 32X Cable from Retro-Access. Like with original hardware there's a couple things to keep in mind here.

  • You'll need to make sure the Game load reset type option in the MegaSD is set to Hard.
  • In the Mega Sg's Settings > Hardware section, the Auto Detect Region needs to be enabled!
  • If your 32X is a launch version (revision VA0) you WILL need to either have the 32X bus terminator (AKA the 32X Extension Unit) attached to the expansion slot of your Mega Sg attached or have a real (powered) Sega CD attached to your Mega Sg. The 32X Expansion Unit by default won't fit the Mega Sg's expansion port and the only way you can plug it in is to remove the the plastic shell from board inside it (via the two Phillips screws) and it should work fine after that. Be mindful of the orientation of the connector and its PCB. If it's upside down the Mega Sg won't boot at all. You can also use the MSDEXP from Mobius Strip Technologies as a bus terminator.

NOTE #1: If your 32X is a VA0 and you don't have the terminator connected to the expansion slot or a Sega CD connected, lots of games won't work correctly. This also occurs with real 32X games with a VA0 32X if you don't have the expansion port populated. So if the 32X is the launch revision, VA0, you'll need to use the terminator or a Sega CD. You can find the terminator on eBay if you need one. If your 32X is a VA1, the bus terminator is built within the 32X itself.

NOTE #2: There's a couple games that won't work at all with the 32X on the Mega Sg. Spider-Man: Web of Fire is an example. Some other games won't even load if you don't press the reset button on the Mega Sg first. Analogue is aware of these issues.

Please refer to Analogue's guide about the Mega Sg + 32X + DAC which can be found here for more information.

Compatibility: Sega 32X CD

The MegaSD is compatible with 32X CD games, however this requires a real 32X. In addition to the 32X hardware, a special adapter is required to use 32X CD games with the MegaSD.

  • MSDEXP is an add-on for your MegaDrive(Genesis) Model 1 or Model 2 and Analogue MegaSG.
- The MSDEXP is a limited production item available from Mobius Strip Technologies.
- The MSDEXP plugs in to the expansion port of your console. It adapts the expansion port to allow the MegaSD to connect directly to the expansion bus.
- The MSDEXP will only work with the MegaSD. It will NOT work with other flash carts.
