I think I saw someone who speedruns in a video have something like it for Mike Tyson's punchout. Basically the program is like live split and compares IGT times for a game. With a list of times for the stages and you can plug in a time you get during a run. And it adds to the right like -1.80 and +1.80 in green and red respectively. Please and thank you.

Ask here: https://speedrun.com/mtpo/forum

Edit: also check the "resources" tab. That's where you can get the splits you were looking for

I looked and didn't want it for that game, but just something like it for a different game. Say the game has IGT for stages and you type in live times and it auto totals the time. I'm surprised this kind of program doesn't exist.

You could ask the MTPO community how they made it. I know that the sonic community and the karlson 3D community use a similar timing method for their runs as well

Livesplit has an option for this

I think the component is Manual Game Time

Thanks now is there a way to make the manual game time split times actually show sum of best?

Edit: Never mind I found you just have to input every split time, but thanks diggity
