SummerCart64 Elite 6TG N64 Flash Cartridge With 64DD Emulation

The SummerCart64 Elite 6TG N64 Flash Cartridge provides high-performance microSD loading, hardware-level Nintendo 64DD emulation, automatic save management and advanced USB-C functionality for original Nintendo 64 consoles.

A preconfigured 16GB microSD card is included with N64FlashcartMenu, emulator applications, supporting files and content organised across multiple classic systems. The cartridge is ready to use straight from the box while still allowing compatible files to be added or reorganised using a computer.

N64FlashcartMenu provides a graphical interface for browsing software stored on the card, with support for organised folders, favourites and recently accessed titles.

The included emulator applications extend the available system support to selected Game Boy, Game Boy Color, NES, Famicom, PC Engine, TurboGrafx-16, Fairchild Channel F, Master System, Game Gear, SG-1000, Super Nintendo and Super Famicom software. Performance varies between individual titles and emulator builds.

At the centre of the cartridge is a Lattice MachXO2-7000HC speed-grade -6 FPGA supported by 64MiB of SDRAM and 16MiB of onboard flash memory. Approximately 14MiB of the flash memory can supplement the SDRAM, allowing compatible Nintendo 64 software with a combined size of up to approximately 78MiB to be loaded.

EEPROM, SRAM and FlashRAM save types are supported with automatic write-back to the microSD card. Unlike flash cartridges that require the console Reset button to be pressed before switching off, SummerCart64 can store compatible save data automatically.

A battery-backed real-time clock supports compatible software that uses date or time functions. The installed CR2032 battery can be replaced when required.

Hardware-level Nintendo 64DD emulation allows compatible .ndd disk images to be used with the appropriate DD IPL file and configuration. Compatibility remains dependent on the software image, region, menu configuration and individual title.

Both the microSD and USB-C interfaces can provide transfer speeds of up to approximately 23.8MiB/s under suitable conditions. The cartridge supports microSD cards with capacities up to 2TB.

USB-C connectivity provides compatible data-transfer, software-development, debugging and firmware-deployment functions. It can be used with supported SummerCart64 computer software, including compatible sc64deployer, UNFLoader and IS-Viewer 64 development workflows.

The USB-C port is not a charging connection. The cartridge receives the power required for normal operation through the Nintendo 64 cartridge slot.

Finished in a Translucent Smoke Grey/Clear shell, the SummerCart64 Elite 6TG is dispatched from UK stock with fast delivery, international tracked delivery to supported destinations and a 12-month Retrolize warranty.

Important Supported-Systems Information

A platform being listed as supported does not guarantee that games for that platform are included on the supplied microSD card. Performance and compatibility vary between individual titles, emulator applications, software revisions and selected settings.

Elite 6TG Version: This is the SummerCart64 Elite version built around a Lattice MachXO2-7000HC speed-grade -6 FPGA.

Preconfigured 16GB microSD Card: The supplied card is prepared with N64FlashcartMenu, emulator applications, supporting files and content arranged across multiple supported systems.

Preconfigured Content May Vary: The exact selection and organisation of content can change between production batches. A system being listed as supported does not guarantee that games for that system are present on the supplied card.

Included Emulator Applications: The supplied microSD card includes emulator applications for Game Boy, Game Boy Color, NES, Famicom, PC Engine, TurboGrafx-16, Fairchild Channel F, Master System, Game Gear, SG-1000, Super Nintendo and Super Famicom software.

Emulator File Identification: gb.v64 is the Game Boy build, gbc.v64 is the Game Boy Color build, neon64bu.rom is Neon64 for NES and Famicom, POMPCE99.BIN and POMPCE99.z64 are two formats of the POMPCE99 PC Engine and TurboGrafx-16 emulator, Press-F.z64 is Press-F Ultra for Fairchild Channel F, smsPlus64.z64 supports Master System, Game Gear and SG-1000, and sodium64.z64 supports Super Nintendo and Super Famicom software.

ROM Converter Utility: rom-converter.py is a supporting file-conversion utility and is not an emulator or game.

Back Up The Supplied Card: Create a complete backup of the supplied microSD card before adding, deleting, reorganising or replacing any files.

6TG & 4TG Differences: This Elite 6TG version uses the faster speed-grade -6 FPGA specified by the SummerCart64 reference design and includes USB-C connectivity for supported data-transfer, development, debugging and firmware-deployment functions. The separate 4TG version uses a speed-grade -4 FPGA and does not provide these USB-C functions.

USB-C Is Not A Charging Connection: The USB-C port is used for compatible data-transfer, development, debugging and firmware-deployment functions. It does not charge or power the cartridge for normal console use.

Menu & Firmware Are Separate: N64FlashcartMenu is stored on the microSD card, while the cartridge firmware is installed on the SummerCart64 hardware. They use different procedures and must not be confused.

Firmware Compatibility: Only install firmware explicitly confirmed as compatible with SummerCart64 and this 6TG hardware revision. Incorrect, incompatible or interrupted firmware installation can leave the cartridge unresponsive.

Expansion Pak Requirements Still Apply: Games and homebrew that require the Nintendo 64 Expansion Pak will still require a working Expansion Pak to be installed in the console.

Controller Accessories Not Replaced: The cartridge does not replace a Controller Pak, Rumble Pak, Transfer Pak, microphone or another controller-port accessory required by compatible software.

64DD Requirements: Nintendo 64DD emulation requires compatible .ndd disk images, the appropriate DD IPL file and the correct configuration. Original physical 64DD disks cannot be inserted or read.

Emulation Performance Varies: Performance varies between individual titles, emulator applications and settings. A system being supported does not mean that every title will run perfectly.

Regional Compatibility: PAL, NTSC-U and NTSC-J consoles are supported. Regional and CIC handling does not convert a game’s original video standard, timing or software region.

Automatic Save Write-Back: EEPROM, SRAM and FlashRAM saves can be written automatically to the microSD card without pressing the console Reset button. Allow storage activity to finish before switching the console off.

Hot Plugging: Always switch the Nintendo 64 off before inserting or removing the cartridge, microSD card or Expansion Pak.
