12. See
Converting Hexadecimal to Decimal numbers to convert the master_version and version before configuring Kore.
Converting Hexadecimal to Decimal numbers
Master_version and server version collected from the login packets
are in hexadecimal number (base-16) and Kore expects a decimal number
(base-10), so converting those numbers are needed before Kore can read
them.
Converting can be made using Windows' calculator or any other site that has a hex to dec calculator.
1. Open Windows calculator
Start > Accessories > Calculator.
2. Go to
View on the upper menu and click on
Scientific.
3. Check the circle beside
Hex.
4. On the calculator, type the number that you got for
master_version and version. In the example, master_version hexadecimal
number is
10.
5. Check the circle beside
Dec.
6. After checking, the number shown should automatically be converted from hexadecimal to decimal.
- You must convert master_version and version.
- OpenKore Help A lot
