asm — Assemble a bank from files

Reads the JSON metadata file produced by disasm and reassembles the binary .Abk file. The "type" field in the JSON determines which importer is used. Data files are resolved relative to the JSON file’s directory.

Usage

portamos asm [options] <bank.json> <output.Abk>

Options

--optimize

Run the Pac.Pic palette optimizer before compressing. Only has an effect on Pac.Pic banks. Can also be set per-bank via "optimize": true in the JSON.

--no-optimize

Disable the palette optimizer even if "optimize": true is set in the JSON.

Example

portamos asm output/sprites.json Sprites.Abk

Bank JSON format

All bank JSON files share a common envelope:

{
  "type": "...",
  "bankNumber": 1,
  "chipRam": false
}

The "type" field is set automatically by disasm. See the bank documentation for the full schema for each type:

"type" value	Bank	Schema
Music	Music bank	Music bank
Samples	Sample bank	Sample bank
Tracker	ProTracker MOD	Tracker bank
Sprite / Icon	Sprite or icon bank	Sprite / Icon bank
Resource	Resource bank	Resource bank
PacPic	Pac.Pic compressed image	Pac.Pic bank
Amal	AMAL animation bank	AMAL bank
Menu	Menu bank	Menu bank
Work / Data	Raw data bank	Work / Data bank
