ZSNES only supports formats which have an open-source, portable, and easy-to-use library. The 7z and RAR formats do not yet have libraries that fill those criteria. If you want the best compression ratio for your SNES ROMs, you should use JMA. Currently, the only publicly available program that can compress and decompress with JMA is NSRT. ZIP deflate64 lacks a decompression library which ZSNES can use, but rumor has it that Nach is working on one.
