Help with WDAT0000.bin #1

Open Sapphire645 opened 5 days ago

Sapphire645 commented 5 days ago

I am trying to edit the WDAT0000.bin file. However, trying to change blocks will make the save file not load. Is there some sort of checksum in PRMDAT.bin that could cause this?

Decompressing and compressing without changes will load. Changes make it not load.

Like in DQB2, DQB1 stores the chunks in layers of size 0x400. The size of blocks is of 1 byte instead of the 2 from DQB2. The Chunk Grid is stored at the very beggining. (0x0 to 0x1200). Chunk data starts at about 0x121C. Chunk count is 0x1204-0x1205.

Items are block ID 0xFF. Bedrock is 0x01, Earth is 0x02...

There is a checksum.

PRMDAT.BIN -> 0x08 - 0x0B

Sapphire645 commented 4 days ago

Chunk data starts at 0x120C*

I can't seem to figure out what the checksum is of...

I'll take a look.

probably could have done it
