Prerequisites

Download files from Android Emulator

.\adb.exe -s emulator-5558 pull /sdcard/Android/data/com.xd.ro.roapk/files/Android/resources/pbbytes 'D:\Downloads\ROAPK\'
.\adb.exe -s emulator-5558 pull /sdcard/Android/data/com.xd.ro.roapk/files/Android/resources/script2 'D:\Downloads\ROAPK\'

1. Download AssetStudio from Github

https://github.com/Perfare/AssetStudio/releases/tag/v0.15.0

2. Use AssetStudio to extract all the .3d asset in pbtyes and scripts folder

3. Clone the following reop from Github

https://github.com/maodijim/pbtk

4. Convert all binary files to proto file

python <pbtk repo path>/extractors/from_binary.py <path to folder pbbytes asset extracted by AssetSutdio> proto

5. Install protobuf compiler

https://github.com/protocolbuffers/protobuf/releases/tag/v3.4.0

# or

go install google.golang.org/protobuf/cmd/protoc-gen-go@v1.25.0 

6. Generate proto file for go

cd <pbtk repo path>/extractors/proto
protoc -I . --go_out=proto_go .\*.proto
# Once Done copy all .pb.go file to ROMProject/Cmds

7. Clone this project

https://github.com/maodijim/ROMEncryption

8. Export Table_exchange, Table_Item, Table_Skill_ClsBranch_* from script2 folder using AssetSutdio

9. Use ROMEncryption to decrypt table_exchange.bytes into table_exchange.lua

#Visual studio is needed to compile the .cs file https://visualstudio.microsoft.com/
# Java https://www.java.com/en/download/

Build ROMEncryption\UtinyRipper first then
Build ROMEncryption
Create folder rawlua at the ROMEncryption.exe folder
Run ROMEncryption.exe

10. Run ./tools/main.lua against table_exchange.lua to get the json formatted exchangeItems.json

# Lua binaries
https://sourceforge.net/projects/luabinaries/files/5.4.2/Tools%20Executables

11. Change the variable in_files to table_item.bytes path and run ./tools/key_val_to_json.py to get json formatted items.json

12. Change the variable in_files to parent folder path of Table_Skill_ClsBranch_* with only Table_Skill_ClsBranch_* files inside the folder then run ./tools/key_val_to_json.py to get skills.json

13. Get access token from emulator

.\adb.exe -s emulator-5558 shell cat /data/data/com.xd.ro.roapk/shared_prefs/XDUserToken.xml

14. Build

$Env:GOOS = "linux"
$Env:GOARCH = "amd64"
go build -trimpath -ldflags "-w -s" .
