I think using SHA-1 hash, to better core’s bug report.
rhash.c/.h in libretro-common are seems I looked for.
(But useful interfaces are static implemented.)
I force to use it, but I got imcorrect result hash…
For gamer, Checksum&Hash are important to management games.
CRC32, MD5, SHA-1, SHA-2, SHA-256, etc.
Please these function will be implement nicely.
I want to use the OpenSSL functions if possible.
