I know that this probably won't interest too many people, but whoever wants to make more guns, I think I discovered a method. All weapons have a "graphic" and a "palette". So if you want more guns, you can change the Sword families of the C and D graphic. All the other swords will fail. Change any C or D graphic Sword to 2D and change the palette for different colors. I am still not 100% sure it always works, but pretty sure. I changed 2 C Swords, the Broad Sword and the Sleep Sword into guns and they work perfectly in game, for example. So here is a list so far of what swords can be changed, their family in ()'s, and this list will be updated because I am making a gun patch:
Broad Sword (C)
Long Sword (D)
Sleep Sword (C)
Ice Brand (D)
I'm pretty sure they do that all the time. I've always wanted to try it too. Patcher has so many utilities it amazes me.
Only C and D families work so far, the others make a weird glitch instead of a gun.
I've learned a lot from you this week Jon. XD
