SimPlayer SummerCart64 Game Card Opensource N64 Game Programmer Compatible with Nintendo N64

SimPlayer SummerCart64 Game Card Opensource N64 Game Programmer Compatible with Nintendo N64

Description:
- SummerCart64 is a custom cartridge (commonly referred to as a flash card) that can be used for developing and playing games on the N64 gaming console. It is s fully functional and completely open-source N64 flash card.
- With the help of integrated support in fast I/O, libdragon/iBcart/UNFLoader, and detailed APIs, testing your homemade software on real hardware has never been easier!
- SummerCart64 adopts features that other N64 flash cards do not have, such as 64DD hardware simulation, automatic backup saving during gameplay, or the ability to run like a regular game pack with direct mode, making it the best choice for players and game developers.

Key Features:
- Fast I/O Performance: Achieves a peak transfer rate of 23.8 MiB/s, ensuring swift game loading.
- 64DD Hardware Emulation: Plays disk dumps directly, supporting combo games and multi-disk 64DD games.
- Automatic Save Backup:Safeguards your progress with automatic save backup during gameplay.

Functions:
Enough space for your ROMs:
- Flashcart embeds 64 MiB of fast SDRAM memory, with additional 14 MiB available from the flash memory, totaling up to 78 MiB - more than biggest known retail ROMs.

Blazing fast I/O:
- Both microSD card slot and USB port operate at peak speed of ~23.8 MiB/s. Even largest retail ROMs (64 MiB) can be loaded in just couple of seconds.

Never lose your progress:
- Every known save type found in the retail games is supported. Saves are automatically flushed to the microSD card (or via USB with PC app attached) during gameplay - no reset button press is necessary!

Complete 64DD hardware emulation built-in:
- Forget about 64DD ROM conversions - SummerCart64 can play disk dumps directly! Combo games (N64 cartridge + 64DD disk) and multi-disk 64DD games are also supported.

Every region is welcome:
- SummerCart64 supports every N64 console regardless of its region. NTSC/PAL switching is done automatically and last detected region is stored inside NVRAM.

Run games with ease:
- Browse, run and manage your game library right on the N64 console with the N64FlashcartMenu - a dedicated menu software for the SummerCart64.

Full control of boot process:
- Direct mode makes testing possible without any interference from the bootloader embedded into SummerCart64, perfect for trying out custom IPL3 replacements giving you control right after N64 boots up.

Dedicated terminal PC app:
- Powerful, and yet simple, sc64deployer app greatly enhances developer user experience.

Outstanding developer features:
SummerCart64 was born as a device for homebrew development first. As a consequence it incorporates many features to ease development of your own games:
- Dedicated PC app for loading ROMs and debug terminal access.
- Simple, command based, communication protocol - both on the USB and N64 side.
- Micro SD card interface with simple, block based, protocol.
- Fast USB interface with well documented protocol.
- 8 kiB buffer for general use with microSD card or USB interface.
- Native support for microSD card and USB interface in the libdragon.
- For libcart support.
- For UNFLoader support - both in the PC app and USB library.
- For IS-Viewer 64 debug interface support in the hardware.

With freedom in mind:
- SummerCart64 project is completely open source - you can modify and build upon it freely as long as GNU GPLv3 license terms are satisfied.
