Sadly at this point I have no accurate idea based on my work schedule and the time it is taking. I am around 7X% done upscaling everything and about 6X% fiddling with the code to integrate all the new changes. While it sounds like I am super close I only have a few hours to work on it every day which is why it is taking so long. I do not want to give a number anymore because I am really bad at estimating my workload but I can see it being easily at least 2 weeks+ more due to how long each upscale takes and the time it takes.
For short reference there is about 1150~ animations to upscale (yes, the game will balloon to a stupid size, near 4GB from this even with compression, also no if you're wondering if I am making a build without animations lol, unless people really want it I guess but that is quite an ordeal to go back and edit out all the animation lines) the only saving grace is I already have the seed/animations just need to upscale.
