No, you don't. You'll be able to find a Linux on windows patch at https://www.speedrun.com/undertale/resources (posted by OceanBagel. Just scroll down patches and it should be there. This guide by Shayy is also really helpful https://www.speedrun.com/undertale/guide/exjem .
can you do sgs on windows?? lol I didn't know~ feel free to correct me if I got anything wrong~
And on Linux, you can do sgs (sea grass skip) which save a decent amount of time too.
Stupid question but do you think changing the colour of sprites will ever be legal. Do you think changing the colours and not the size of the sprites can be legal? Or would that make speed runs 1: too hard to verify and 2: cheating easier to a certain extent? It would be really cool to do a genocide run with Chara's sprite instead of Frisk's. thx for your time~
Does language affect anything? Can I submit a run in another language?
when i try to apply the data.win patch the outcome is always "This patch is not intended for this rom!". what do I do? what did I do? (the patch for the runner worked I think)
thx~
Another dumb question: how do i tell if im running Undertale PC or Linux?
Does early burnt pan work on microsoft ver or is it a Linux thing?
