"You Must use the playoff ROM, since it has 99-minute overtime.
I have also set it up with playoff matchups. So you should be able to switch to 7-game playoff mode and play your series. The higher ranked team will be the home team to start."
I try before to play a 7-game playoff mode series on the net, but there was a bug with the original nhl94 rom, and with the Blitz rom too, at the end of the first game, when you return on the start screen and you choice "continue playoffs " to start the second match, the two teams are switched with other teams...
and it was impossible to finish the series, is that bug fix in this new rom ?
