I don't know if it's possible, but if you could make a Replay Mod version for 1.8.9, that would be GREAT. I know there's already a 1.8, but the reason I want this is because of
1) 1.8 runs a lot slower on my computer than 1.8.9
2) It's more convenient to not have to switch versions every 2 seconds.
3) Many people use 1.8.9 still, so making a Replay Mod for this version will let that majority of people play on the most recent version before the update most consider to be horrible.
Even if you can't implement the mod into 1.8.9, I thank you for your time! :)
The 1.8 versions are practically the same. You can even join 1.8.9 servers, with 1.8, so I don't think a 1.8.9 version would be that useful. The only things it had, are bug fixes. (Actually, some of them are pretty good fixes. For example, I couldn't use the @ sign in minecraft, because of a bug in 1.8)
I always used the Replay Mod to go back into PVP rounds I played on servers and get some nice screenshots for youtube thumbnails. The problem here is that 1.8 got a bug that causes people to stay invisible for a few seconds after they died and that is a big problem in PVP. That's the reason why I prefered 1.8.8 or 1.8.9 and also the reason I stopped using Replay Mod. I really would appreciate a version for 1.8.8 or 1.8.9.
