Caravan Nova

Shining Force ROM viewer / editor (SF1, SF2, SFCD partial) — runs entirely in your browser. Use Open Game File with your own legal dump or SFCD .iso (nothing is uploaded to a server). Exports download as .bin / .smd / .ips.

ROM & project metadata

Writable regions (merged offsets)

Fixed-size slots (spell/item icons, growth table) and entry points for compressed assets. Overlaps are flagged in the line below the list.

ROM lab — coverage metrics, Caravan tree, hex / patches

Byte-weighted scores use sf2splits.txt-derived atlas ranges plus Nova linker hints. Raw patches apply to the in-browser ROM session after Open Game File.

Caravan-style category tree (bytes per atlas id)

Editability parity (vs Caravan, SF2Edit, SF2DISASM)

Hand-maintained matrix toward 100% SF1 / SF2 / SFCD / Gaiden editability. Highlight rows where Nova decodes or patches ahead of legacy UIs. Levels: none · view · partial · edit · rebuild (DISASM workflow).

allowOverlap

Decompress probe uses the Offset above (GET APIs).

Growth curve (one level)

curve 1–5 level idx 0–28 a (u16) b (u16)

Replace entire curve (29 levels × { a, b })

Uses curve id from the field above. Body: POST /api/rom/patch/growth-curve.

Advanced — compressed streams (basic literal / stack same-length)

Basic-compressed literal patch

Body: romStreamOffset, outputPatchStart (decoded offset), patchHex. Empty stream offset falls back to hex panel offset.

Stack-compressed same-length replace

sliceHex must match compressed blob byte length on ROM. Optional verify decompress.

Or paste exactly 384 hex characters (192 bytes) — no PNG.

Ally rows (JSON bodies)

Use ally index 0–29. Dialogue: dialogueRows array of 3 { "portrait": n, "speechSfx": n }. Battle: 3× { "classId", "battleSpriteId", "palette" }. Map: 3× { "mapspriteIndex" }. Start: startClassId, startLevel, startItemsRaw length 4.

Apply IPS patch

Multipart field ips. Default applies against the IPS baseline; choose session to patch the live in-memory ROM (includes unpersisted edits). Optional hashes prevent silent mismatches.
