[Scummvm-devel] Residual: Savegame format

[James 'Ender' Brown]

Honestly, we really don't need to support the original save format.
Given the way .gsv files work, and endian, I don't believe a compatible
save format could be cross-platform interchangable.

IMHO it would better to create a new (incompatible) save format from
scratch, as we do for most of the engines ScummVM-proper supports.
