This includes all the collision stuff needed to spawn `target`, decompiles the sparticle code and adds some of the PC hacks needed for merc to run (it doesn't work quite right and looks bad, likely due to a combination of code copied from Jak 2 and the time of day hacks). There are a bunch of temporary hacks (see commits) in place to prevent the game from crashing quite as much, but it is still extremely prone to doing so due to lots of missing functions/potentially bad decomp. --------- Co-authored-by: water <awaterford111445@gmail.com>
