I found that objects have flags that control things such as activity, collision, whether the sprite is shown, and whether anything happens if you interact with it. There might be much more to this, but those flags are enough to e.g. activate the unused saveblock in Koopa Cruiser. And I was able to activate the stuff in the room before Popple & Birdo, but it turns out those were just stuff used for a cutscene.
There might be a luigi object somewhere in there too, not shown in the screenshot..
I will try to find unused stuff in other rooms now. But maybe people at yoshi's lighthouse already went over this, so maybe there's nothing left to be found.
(
Luascript 0.12.5 which includes the npc flags )
EDIT:
*** Room 9 (Test room 6)
Actor 5 (single pedal platform) is offscreen and disabled, but doesn't have any reaction when interacting with it.
*** Room 30 (End cinematics, when they're in the plane laughing)
Actor 7 might be an invisible hoo bean block, but I can't confirm.
There are 4 active FCHR (Actors 3~6) objects, but disabling them doesn't have any visual effect.
*** Room 62 and Room 61 (Bean castle interior)
In both those rooms, there are two knight actors that have dialogue, not sure if used or not.
*** Room 76 (first room of mountain enemy area)
Actor 3 is an unused bean person NPC that says "I'm tired of living in the sticks. I want to live someplace cool, where there's lots to do!"
Actor 4 and 5 are badge sprites, also unused in that room.
*** Room 131 (Bean area, south east, beach)
Actor 7 is some invisible block (Hoo bean), unreachable in an out of bounds section of the room.
*** Room 169 (Oho oasis, south-west)
Actor 6 is a red Oho Jee, located on top of the radio, appears to be unused and possibly for testing the black fade-out effect when using the radio.
When talking to this Oho Jee, it works the same as if you interact with the radio.
*** Room 172 (Oho oasis, north-east)
Actor 6 is a snail. appears to be unused.
It would be there in addition to actor 5 (snail), which looks like two snails kissing. lol
*** Room 173 (Oho oasis, south-east)
Actor 4 is a crab, it might be unused OR otherwise used for the cutscene when landing in this place.
Actor 7 is a blue Oho Jee, located on top of the radio, same deal as in room 169.
Actor 9, is inactive and when made active it's invisible still. Not sure what gives.
*** Room 206 (Seabed)
There are a few invisible Hoo Bean blocks in this room, not documented on vgmaps.
Used and accessible.
*** Room 219 (University, main hub room)
There is one invisible Hoo bean block in this room, not documented on vgmaps.
Used and accessible.
*** Room 221
One invisible hoo bean block, etc.
*** Room 263
One invisible hoo bean block, etc.
*** Room 274 (Mushroom kingdom, 1st room)
Actor 13 is a bowser sprite?
Actor 14 and 15 are some unloaded invisible objects?
Not sure which one is supposed to be the known unused toad object in this room.
*** Room 344 and 345 and 353 and 354 and 363 (Joke's End)
have one invisible hoo bean block each, undocumented, etc.
And is the firmware I'm using fine?

The objective would be to craft words by inserting new letters, swapping the existing letters, replacing the existing letters with new ones, or deleting existing letters.
Finishing a level fast will earn more points.
Not sure if this idea yields much playability and interest, but it's been floating in my mind for a while now.
Not sure if I should script it quickly in emu-lua for the sake of it, or if I should get into javascript/Html5 again or maybe learn a new language (which I don't plan to do in the near future, but maybe later)...
Any input on this game idea is welcome, including improvements to the screen design or the idea itself.
