Hi, I believe this was fixed in https://github.com/mmitch/gbsplay/commit/af783619b45d0def5824976b0af151bf2a3edc4e but we haven't gotten around to making a newer official release yet.
In the meantime you could try cherry-picking this commit (and maybe a060526a51bf6b1d3e7d0472fc61971ba1ee7b00 as well to fix the rand_long warning). Cheers, -- Tobias PGP: http://8ef7ddba.uguu.de
