Full RecompilationBytecode and scripts decompiled to IR, type-inferred, optimized, and emitted as idiomatic TypeScript. Not interpretation — real codegen.
Replacement RuntimeOriginal engine APIs (Flash, GameMaker, Twine) replaced with modern TypeScript implementations. Platform-agnostic — browser or native.
Preservation FirstAccurate reproduction over improvement. Behavioral equivalence is the bar — source-language bugs are preserved, not fixed.
