+This tool upgrades OGKR charts from 1.6.0 (Act 2) to 1.7.0 (Act 3 (SDDT 1.45)). Useful for charts that were deleted in 1.45 or earlier. 
+
+### Why
+SDDT 1.45 added an extra number to `[B_PALETTE]` rows, used by Random Access Emotions and MEGALOVANIA, but seemingly set to 0 everywhere else. S*GA adjusted everything that was still in the game as of 1.45, but older deleted charts (e.g. Hibachi) load without any bullets. This script fixes that.
+
+### Usage
+```sh
+npm i
+npx tsc index.ts
+node index.js <Axyz/music>
+```
+Where `Axyz` is an omnimix option directory.
