I was wondering ive been using an expension pack and i just read that it slow down the menu or something. Would it save me a couple seconds if i had a jumper pack instead? I can feel it the menu is a bit slow but does it really make a difference?

I don't have a jumper pack but i have a friend that would probably borrow me his if it worth some seconds.

Hello! Yes, the expansion pack does slow down the game by a couple of seconds. I don't have the exact total on me, but it is enough to warrant top runners to be strictly using the jumper pack!

I’ll take a closer look later when I’m home, but I looked through your 9:46 PB mariokart, and your out of game time was 1:39. There were 2 extra restarts that cost 3-4 seconds each, and other slightly suboptimal menu’ing which probably only cost a couple seconds total. Without soft resets, a good out of game time with a jumper Pak is ~1:15, so I believe the Expansion Pak lost approximately 10-15 seconds

3 years later haha!! thank you @Nami im not a big speedrunner of the game, just did it for fun since i wasnt bad at the game, i was gonna work on details such as menu, and couple splits which i needed to learn to save big time ( school and mineapolis) and try to get a better run. The one i summited was just ok but noway near my best splits. sadly i got lost into call of duty and didn't play THPS anymore since then. I was just recently thinking about practicing it and at least get a sub 8 run, which imo is respectable for someone who don't really speed run the game. Im reallylooking foward to play this masterpiece again soon and ty again for the specification on the time save i could get!!
