pine_write16
Write a 16-bit little-endian value to PS2 memory at a 2-byte aligned address. Overwrites two bytes; use for 16-bit cheats like HP or score.
Instructions
PURPOSE: Write an unsigned 16-bit little-endian value to EE main address space. USAGE: For 16-bit cheats/pokes (HP, score, coordinates). For single bytes use pine_write8; for 32/64-bit use pine_write32/write64; for big-endian fields byteswap first (this tool always writes little-endian). Snapshot via pine_save_state for rollback. BEHAVIOR: DESTRUCTIVE: overwrites two bytes (low at address, high at address+1) with no undo. Direct write — bypasses TLB; writes to read-only regions (BIOS) are silently dropped. Address MUST be 2-byte aligned. PINE on PCSX2 does NOT enforce alignment — unaligned access typically returns whatever bytes are at the aligned address below, silently corrupting the value. If you need an unaligned multi-byte read, use pine_read_range and assemble the bytes yourself. Errors on connection drop or PINE FAIL.

Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| address | Yes | Absolute byte address in the EE main address space (NOT a per-domain offset). Pass as a number; hex literals like 0x00200000 are fine. Reads 2 consecutive bytes starting here. MUST be 2-byte aligned (address % 2 === 0). PINE on PCSX2 does NOT enforce alignment — unaligned access typically returns whatever bytes are at the aligned address below, silently corrupting the value. If you need an unaligned multi-byte read, use pine_read_range and assemble the bytes yourself. Useful range: 0x00100000-0x01FFFFFF for EE main RAM (where 99% of game state lives). An unmapped or invalid address returns a PINE FAIL response. | |
| value | Yes | 16-bit value to write. Must be 0-65535 (0x0000-0xFFFF). LSB lands at `address`, MSB at `address+1`. For signed 16-bit values, encode as two's complement (e.g. -1 → 0xFFFF). Values outside the range are rejected by the schema. |
