Spikestuff is correct, if the gameplay is identical and the Playstation version is more accurately emulated (which it probably is), feel free to use that version.
Judgment notes will always be found at the bottom of the submission text, however I will be willing to restate it here. When looking at this submission I found improvements constantly over the course of the TAS by correcting minor mistakes. Some of the improvements I uploaded in a
userfile here but not all. I'd recommend using frame advance in order to better improve the TAS next time. If you find it more convenient, you can use a tool included in Bizhawk called TAStudio that many newcomers find more intuitive. Additionally I'd recommend finding RAM Addresses to help determine position etc. If you continue to use the N64 version you can use
this list I made to start off, but if you use the playstation version, you will need to find the values on your own. I would not recommend the latest release of Bizhawk, 2.3, as it is currently unstable and would recommend 2.2.2 instead for TASing.
