ROM: Magical Puzzle Popils

game says backup data is initialised.
edit mode should display a blank canvas ready for a level to be built.
but it displays random tiles.
if I scroll through the 30 editor slots, the game will crash due to the random data.

Have also tried initialising the save data from the game options screen.

Usually they just save it raw.

ROM: Magical Puzzle Popils.gg would be 8192bytes long

(i noticed because my saved offsets were not showing the correct data when browsing the crater .sav)

edit: I see this is already on your roadmap

I'm not familiar enough with GG or Z80, but could the disassembler present (some) data as strings?

at the end of Magical Puzzle Popils.gg there are a bunch of English strings, and some elsewhere. Would be great if these could be displayed as is. Even better if it could display the Japanese text, but that seems to use an encoding I'm not familar with.

the transition is solid black in OpenEmu and CrabEmu

1. load game
2. choose map edit
3. choose slot 1
   (observe transition)

5. press enter/start to bring up edit menu
6. choose end edit
7. choose yes
   (observe transition)

disassembly seems to only go as far as $0FE for some reason?
