pine_write32
Write a 32-bit little-endian value to a specified aligned address in the emulator's EE main memory for cheats or data modifications.
Instructions
PURPOSE: Write an unsigned 32-bit little-endian value to the emulator's EE main address space at the given absolute address. USAGE: Use for 32-bit cheats and pokes — timestamps, large counters, RGBA colors, the lower half of pointers. For single byte / 16-bit values use pine_write8/write16; for true 64-bit fields use pine_write64 — chaining two pine_write32 calls is non-atomic and can be observed mid-update by the running game. For big-endian layouts, byteswap into a little-endian value yourself first. BEHAVIOR: DESTRUCTIVE: overwrites four bytes starting at address with no undo. Direct memory write — bypasses TLB protection and DMA mediation; writes to read-only regions (BIOS) are silently dropped with no error. Address MUST be 4-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. Values are NOT truncated by this tool: the schema rejects anything outside 0-4294967295 (0x00000000-0xFFFFFFFF) before the call ever reaches PINE. Returns an error if the connection drops or PINE returns FAIL on a wholly invalid address.

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 4 consecutive bytes starting here. MUST be 4-byte aligned (address % 4 === 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 | 32-bit value to write. Must be 0-4294967295 (0x00000000-0xFFFFFFFF). LSB lands at `address`, MSB at `address+3`. For signed 32-bit values, encode as two's complement (e.g. -1 → 0xFFFFFFFF). For floats, reinterpret the IEEE-754 bits as an integer first. Values outside the range are rejected by the schema, NOT silently truncated — pass the value you actually want stored. |
