家庭内で「そこで働いてたんだ！時期被ってた？」って話があり、思わぬ空間的な縁があるかもと思ったので、場所の記録を共有できる思い出マップって初Webアプリを作った！ まず記憶を遡って歴代職場をまとめた！ 皆さんの思い出の場所もシェアしてみてください！ memory-map.sugiy.com/e5f3b11… #memory_map

#MemoryMap #Memory_Map

memory_map->map_size = 0x1230ってどゆこと？？ 数値出力の関数間違えた？

We can modify the MEMORY_MAP and PROGRAM_TREES segments as shown below to include all of the memory maps - then we just need to re-import the file into Ghidra and we're ready to go
