I was browsing the scores for the Athlon II 240 and I came across these scores:
http://hwbot.org/community/submission/960976_pipejarcore_wprime_32m_athlon_ii_x2_240_12sec_265ms
http://hwbot.org/community/submission/960987_pipejarcore_wprime_1024m_athlon_ii_x2_240_6min_31sec_609ms
He/she is using wPrime 2.x, that is not allowed is it?
