-- Driver (#889): export a .sav from a save that never came from a ROM import,
|
|
-- the case that used to write a save with no map context at all -- no map
|
|
-- header, no tileset header, sound id 0 -- so a real Game Boy continued into a
|
|
-- garbled map and hung on a white screen.
|
|
--
|
|
-- Saves the game in two places (an interior and an outdoor map with
|
|
-- connections), exports each, and prints the bytes the engine reads back on
|
|
-- Continue so a human can eyeball them, plus the export path to load in an
|
|
-- emulator.
