Pokered Save Editor 2: grounding item data in the game's own source

Splitting the shop's item groups using the original game's disassembly as the authority, plus accented names and detailed tooltips.

A theme running through Pokered Save Editor 2 is that claims about the game should be checked against the game, not guessed. This day put that into practice on item data.

The disassembly as the authority

The Market’s flat “Normal Items” list was split into meaningful groups, with the documented Pokémon Red disassembly (pret/pokered) as the oracle. Two of its data files settle the questions:

  • data/items/prices.asm — the per-item buy price (sell is half). A price of 0 means the item can’t be priced or sold.
  • data/items/marts.asm — what’s actually stocked; the buyable set is the union of every reachable shop’s inventory.
  • data/items/vending_prices.asm — the Celadon roof vending machine (a separate vendor).

The membership sets were transcribed straight from those files into the model, each index commented with its item name:

// indices transcribed from pret/pokered data/items/marts.asm + vending_prices.asm
static const QSet<int> kBuyableInGame = { /* Poké Ball, Potion, Antidote, …,
                                             TMs 01,02,05,07,09,17,32,33,37 */ };

bool ItemMarketModel::buyableInGame(ItemDBEntry *e) {
    return kBuyableInGame.contains(e->index());
}

Items group into Normal (a shop sells it), Vending Machine (the three roof drinks), and Special (priced but no in-game vendor). Items with no price at all are listed nowhere, because there’s genuinely no way to buy or sell them.

A naming sweep, and the trap inside it

A display-wide sweep corrected “Poke” to the accented “Poké” everywhere user-visible — Poké Mart, Poké Ball, Pokédex — touching only display strings, never identifiers. That tripped a subtle trap: one item name doubles as a lookup key in the map data, so renaming it orphaned a link until the data reference was updated to match:

maps.json:  "item": "Poke Ball"   →   "Poké Ball"   (kept in lockstep with the rename)

A reminder that display text and data keys aren’t always separable. The editor’s target was also documented explicitly as the US English release of Red and Blue.

Detailed item tooltips

Finally, the long-deferred detailed-tooltip feature was built as a working vertical slice: an optional info field per item, plumbed through to a tooltip with a title and wrapped body, with the first eleven items’ descriptions authored and checked against the disassembly. The rest of the items, and wiring the tooltip into the other screens, are the next steps.
