Suikoden 1 Gameshark Codes Have All Items -

Instead of “all items,” use slot-specific codes:

Item in slot 1 (first bag):
300C1914 00XX (XX = item ID)
300C1915 0063 (99 quantity)

Item slots range from 0x800C1914 to 0x800C19F3 (48 slots).

Example IDs:

Ask any Suikoden veteran, and they’ll tell you: running out of room in the item bag is a nightmare. But with GameShark codes, you can bypass inventory limits, dupe rare finds, or gift yourself every item in the game.

The most famous “All Items” code for Suikoden 1 (PS1) is:

800C18C4 2404
800C18C6 A0A4

But — and this is a big “but” — it’s notoriously unstable. It often overwrites key story items, breaks quest flags, or corrupts save data. Why? Because Suikoden’s item IDs are tied to event triggers (e.g., the Old Book volumes, Window Sets, Letters of Introduction). suikoden 1 gameshark codes have all items

Unlike modern games that use a simple slider, Suikoden 1 organizes its memory into blocks. The "All Items" cheat generally comes in two flavors: One that fills your bag with 99 of every standard item, and one that manipulates the treasure chest flags. The code below is the most stable, well-documented version for the North American (NTSC-U) version of the game. Instead of “all items,” use slot-specific codes :

Game Version: Suikoden (NTSC-U / SLUS-00292)
Code Type: Gameshark v1/v2 (Raw)

80073360 # 2404
80073362 # 0063
80073364 # A404

How to use this code:
This specific string is a "modifier" code. When activated, it instructs the game to write a specific value (99) into the memory address controlling your first item slot. In practice, most pre-packaged "All Items" code lists for emulators consist of roughly 200 lines of code, each line writing 99 pieces of a specific item into consecutive inventory slots.

If you are using a modern cheat database (like those found in DuckStation or PCSX-Reloaded), look for the entry labeled "Have All Items (Except Key Items)". That version filters out the story-critical flags, leaving you with weapons, armor, runes, and healing goods. Ask any Suikoden veteran, and they’ll tell you:
