Using SummerCart64

SummerCart64 is a brand new relatively cheap open source flashcart that supports 64DD games without the need of converting them to a cartridge format.

This means all 64DD disk images can work on it without any hacks required. It does as much as the EverDrive 64 X7 and even a bit more for cheaper.

As of this writing (2025-01-15), these flashcarts are mass produced on AliExpress, in a way that I don’t necessarily find ethical and neither does the team behind this project. Watch what you buy, it can be cheap, possibly that they might cheap out too much.

So please know what you’re doing, and please don’t blame the developers if something is wrong with the cartridge you bought. This is an open source project, anyone can do anything including doing changes not recommended by the developers.

You can find more information about SummerCart64 on its website, including a recommended store (not affiliated).

Instructions

Basic Flashcart Setup

• Make sure the cartridge is updated to the latest firmware using USB. Click here to find the latest firmware version.
  • You can update the firmware by using sc64deployer through the command line with sc64deployer firmware update <firmware file> like this.
    
    
  • This is the only way to do it. Doing automated updates from SD card is not technically feasible.
• You can also synchronize the real time clock to the one from your computer by doing sc64deployer set rtc.
  
  • You can now set it up from the menu.
• You also need to put the sc64menu.n64 menu executable on the root of the microSD card. Click here to find the latest menu version.
  • Update: You can now put the sc64menu.n64 to the SD card via USB by just doing sc64deployer sd upload <path to sc64menu.n64> if you don’t want to remove the SD card everytime.

64DD IPL Setup

• Click here to download the 64DD IPL ROM archive for SummerCart64.

• The 64DD IPL ROM files are now setup, you can now just play 64DD games.

Remember to unplug the 64DD if you have one to play them through the flashcart.
