Two things I can think of:(posted 9576 days ago)1. (The best solution) Send a copy of the new recording to Zwaxy, explain the situation to him, and ask him to replace the old one by the new one.
2. Specify a different version of MAME (which would result in the resulting filename being different) and, in the remarks for the upload, specify what the real version was you used.
Cheers, Ben Jos.
