Hi! I'm investigating Happy Home Designer data by using HxD. Here's my progress! Feel free to help me identify Unknown Data.

First of all, I'm using this thread to fix 'takumi.dat' after editing data with HxD: WulfyStylez's ACRehash.

Please, read my document:

• Unknown Data - 0 > 19F.

• House Length (Full) - 1F6 > 1B3EAB // Note: Empty houses are named "School" as placeholder. The whole 'House Length' could be the blocks reserved for all houses available to build in the game. Example: 1076 (One house block length) - Start: NPC name, for example SZO = Digby. End: Probably house name (for online upload). Extract ROMFS using Citra emulator and check NPC folder. Preview each .bcres file using Ohana Rebirth.

• Facility Length (All) - 1B3ECE > 1BFC1C // Note: One building block length: 111F. Start: Building type. Example: 'Hospital'. End: Building name (The custom name you write for online upload in update 2.0). Custom online name usually found at the end of each facility block. First facility starts at 1B3ECE. Next one is 'Hospital' (1B5008). Last one is 'Hotel' (1BD9C8). Unused data at the end of the block: Check '1BEB00'. Check complete facility list on 'FILE05'.

• Pattern Length (Full) - 1BFC58 > 1FF0D7 // Note: Copy & paste 'FILE01' values to revert 'Pattern list' to default. One pattern block length: 870. Start: Pattern name, Author and Town (1BFC58 > 1BFCA8).

• Keyboard Data - 1FF0F9 > 1FF151.

• Player Name - 1FF152 (7 letters MAX) // Note: Remember to write each letter with '00' values in between.

• Item Data - 1FF164 > 1FFD0F // Note: Filling this block will '00' values will empty your Costume list & Furniture list. Filling this block with 'FF' values will fill your Costume list & Furniture list completely with all items available in the game. House / Furniture upgrades are also affected.

• Unknown Data - 200874.

• Emotion list - 200940 > 2009AD // Note: Reverting block values to default will empty your emotion list. You can still create new houses and start to fill emotion list again. Copy & Paste 'FILE02' values.

• Book Data (Villager list) - 2009CC > 201D56 // Note: Reverting block values to default will empty your villager list. You can still use 'Amiibo Phone' to call a Villager and build the house again in order to reappear in the Book. Copy & Paste 'FILE03' values.

• One Villager (Book Data) - 2009CC > 2009D7 // Note: Check 'FILE04'.

• Unknown Data - 201F60 > 205B9C.

• Unknown Data - 205ED0 > 206629.

• Unknown Data - 20E5E0.

• Event Data - 2BDB50 > 2BDB54. Available options (for 2BDB50): 00 = Name & Gender Scene; 01 = First Meeting Scene; 07 = Dressing Scene; BF = Goldie Scene; FF = Normal (Glitch). Available options (for 2BDB50 > 2BDB54): FF FF FF FF FF = No Event Day (Check 'Amiibo Phone Data' as well); FF 3F 40 7F 00 = Only Isabelle is enabled; FF BF 6F FF 1F = Only Digby is enabled.

• Scene Data - 2BDB46. Available options: 01 = Selecting Facility (Crash); 03 = School; 04 = Inauguration (Crash); 05 = End of Inauguration.

• House (Edit) Scene - 2BDB40. Available options: 01 = House Placement Map; 02 = House Size Menu; 03 = House Edit.

• Amiibo Phone Data - 2BDB53. Available options: 00 = Disabled; FF = Enabled.

• Time Data - 2BDB68 > 2BDB69. Available options: 01 FF = Morning; 02 FF = Afternoon; 03 FF = Night; 04 FF = Midday.

• Unknown Data - 2BE318 > 2BE640.

• Unused Data - 2BE7EC > 2BE923.

• Extra: 2BDB40 (Same effect as 'Scene Data').

• Extra: 2BDB3A > 2BDB43. Copy & paste value '06 00 A0 01 03 03 03 03 0B 03' to enable Edit Mode on any part of the game. If you enable this code, puppet00.bcres will load on the stage. This puppet is not inside NPC folder, so the first Villager on the list is ant00.bcres.
