With the most recent patch to the GOG version, the IGT issue in the menu seems to be fixed and so we will allow it on the board. We are still recommending that you use the Classic REbirth patch for the quality of life features, but the base GOG version is perfectly fine. As always, running in Japanese will save minutes over other languages, so you should run on the Japanese version, but the LiveSplit autosplitter is set up to work with the English version as well.
