i use caveshark.
it cant edit maps.. so you download a speedrun save and mod the weapons...
it can change the weapons youre using, change their ammo, their level, your life, your exp, your inventory items..
its really easy to use... probably the easiest one ive ever seen.
hey man when you learn how to make mods we can start a simple mod together.
i can mod maps, speech, sprites and some events.
im currently working on a little revive for the ballos story mod.. im gonna make some map changes.
