Essentially I cannot for the life of me find a way to convert perfectly openable .rblx to a proper and usable rblx file in any of the current and snapshot builds of Novetus and with the LPC... The outputs strangely work well with the moderne, current version of Roblox Studio. Is there any feasible way this can be remedied? I'm trying to basically port games that haven't been supported for ages (games from around 2009-2012, nothing too demanding) so that they can be played on any optimal client of roblox in Novetus.

If anyone can help out, please feel free to lead the way in fixing this!! Thank youuuuu
