I have released a new version of kobopatch (along with patches v40) with some new assembly manipulation instructions.

The new features in this release are:

- New FindBaseAddressSymbol instruction: This finds the base address of a function. Use the demangled c++ symbol name (or the c symbol name). The advantage of this instruction is offsets of functions using this instruction do not have to be recalculated every firmware version.

- New ReplaceBytesAtSymbol instruction: This instruction combines FindBaseAddressSymbol and ReplaceBytes.

Examples:

Code:

# Making a setting always true (offset 53 is the toBool function call inside the setting getter).
# This example uses all the new assembly manipulation instructions from the last two versions to reduce the number of offsets to update every version from 3 to 1.
  - ReplaceBytesAtSymbol: {Symbol: "ApplicationSettings::readABookShown()", Offset: 53, FindBLX: 0x40491c, ReplaceH: 4F F0 01 00}

And other ones coming soon once I update them.
