I'm not sure if anyone realizes this but if they upload a Beta14 inp file and select it's Beta13, when they "Say" it's Beta14 in the text box: The file name generated on submit time will say Beta13, EVEN AFTER you change it back to Beta14 when it becomes selectable.(posted 9469 days ago)So when users download a couple of different inp.zips, their filenames may say bbh_railroad_9837472_m36b13.zip when the recording was actually made in m36b14 and even after the entry is changed to say the inp was recorded in m36b14.
I think it would be courteous to hold off of new beta uploads untill the beta selection is in tact.
This is sort of a bug in the site, downloaded filename don't necessarily correspond to the mame version used... but zwaxy is way to busy i think to fix this.
