There was going to be a Picross minigame, as we saw in the Space World '97 demo ROMs. A separate Pokémon Picross game was also planned but canceled. The game's actual code is not available—its files, like piku.h, were completely removed—but should be possible to disassemble in pokegold-spaceworld.
Some unidentified labels in pokecrystal have to do with Picross.
| Disasm Name | Original Name | Disasm File | Original File | Details |

PRG_PlayPicross |
data/special_pointers.asm | EVENT.DMG | |
ClearBGPalettesBufferScreen |
PlayPicross |
engine/events/specials.asm | EVENT.DMG |
This commented code in EVENT.DMG (corresponding to ClearBGPalettesBufferScreen in engine/events/specials.asm) would have called the Picross game. (The implementation of PikuGame was completely removed.)
