batch re-profiled nekop2 through pokemini. mupen64plus renamed to
mupen64plus_next. new profiles: nes, mupen64plus_next.
validation functions (_build_validation_index, check_file_validation)
consolidated in common.py — single source of truth for verify.py
and generate_pack.py. pipeline 100% consistent on all 6 platforms.
pure python GF(2^233) field arithmetic, binary curve point operations,
and ECDSA-SHA256 on sect233r1. verifies OTP CTCert against nintendo
root CA public key. zero dependencies. sign+verify round-trip tested,
n*G=O verified, wrong key/message rejection confirmed.
pure python RSA-2048 PKCS1v15 SHA256 for SecureInfo_A,
LocalFriendCodeSeed_B, movable.sed. AES-128-CBC + SHA256 for otp.bin.
keys extracted from azahar default_keys.h, added RSA/ECC sections
to aes_keys.txt. sect233r1 ECC not reproducible (binary field curve).
