Semi-related example, my delta 3d printer converts g-code to a preprocessed internal binary format to avoid runtime trigonometry. In other words, one can pre-process a well-known format to an internal format for performance reasons.

2448 vs 2048 is only a 20% overhead. ?

I mean, the point is you support both the old and new formats, and when games come around where supporting raw ROMs gets too painful (per-gamw hack tables of mappers and such), you tell people to start using less shitty formats for those games to slowly push them.

BTW, fun thing to ponder about. Wii/GC games are padded to the full disc size with random data, but IIRC the mastering tools use a predictable PRNG, which means you can compress them by a huge amount depending on game size, but the decompressor needs to implement that exact algo.

(of course the passing data is not needed for the games, but is needed for archival fidelity)
