Sp5001.bin [FAST]

I’m unable to provide a full feature description for a file named sp5001.bin because this specific filename is not part of any widely known or documented software, hardware, or data standard.

1. Visual Output (4/5) When loaded onto a Gameduino shield, this binary renders a high-resolution, colorful Sierpinski triangle. For a hobbyist microcontroller from the 8-bit era, the visual fidelity is impressive. It demonstrates the "J1" coprocessor's ability to handle complex geometry that would choke a standard Arduino AVR chip. It’s a striking image that proves the hardware is working correctly. sp5001.bin

3. Header Specification

| Offset (bytes) | Length (bytes) | Field | Data Type | Description | |----------------|----------------|-------|-----------|-------------| | 0 | 4 | Magic | uint32 | Fixed value 0x53503130 ("SP10"). Validates that the file is an S&P 500 binary dump. | | 4 | 2 | Version | uint16 | Currently 0x0001. Future versions may add fields; always check this first. | | 6 | 2 | HeaderSize | uint16 | Size of the entire header (including this field). Allows future extensions. | | 8 | 8 | StartDate | int64 (UNIX‑ms) | First timestamp in the dataset (UTC). | | 16 | 8 | EndDate | int64 (UNIX‑ms) | Last timestamp (inclusive). | | 24 | 4 | RecordCount | uint32 | Number of data records that follow. | | 28 | 4 | RecordSize | uint32 | Size of each record in bytes (fixed). | | 32 | 4 | Flags | uint32 | Bit‑mask – e.g., 0x1 = contains adjusted close, 0x2 = includes dividend data, etc. | | 36 | 28 | Reserved | – | Zero‑filled for forward compatibility. | | 64 | 0‑? | Optional Sections | Variable | May contain JSON‑encoded field‑map or a SHA‑256 checksum (if Flags indicate). | For a hobbyist microcontroller from the 8-bit era,
