Here you are:
Dungeon_A1

Dungeon_A2

Dungeon_A4

Or, if you're like me, and don't like the random black patches in the walls...

Dungeon_A5

Dungeon_B (This is the one I've been using for a while, so they may not be as high quality as the others. If you notice anything weird on something specific, then let me know.)

Dungeon_C (Same applies to Dungeon_B. If you noticed some pixels out of place somewhere, let me know and I'll fix it.)

Outside_A1

Outside_A2

Outside_A3

Outside_A4 (And now this is really really big and I'm not sure how to fix it...)

Outside_A5

Outside_B (like the Dungeon_B tile, these might need some work. Lemme know if you notice anything weird.)

Outside_C (Same as Outside_B--might be weird, lemme know if you notice anything.)

Inside_A1

Inside_A2

Or, if the half-missing trims on blue carpet bothered you as much as it bothered me, here's the alternative I made.

Inside_A4

Or, the no-black-hole version if you're like me and don't like the random and out of place black hole.
Inside_A5

Inside_B

Inside_C
World_A1

World_A2 (those freaking trees took waaay to much energy)

World_B

!Door1 (These are technically tilesets, yet not, so...)

And I made a green door for myself, so if you're interested, then go for it.

!Door2

!Door3

!Chest

!Chest Recolours (I needed for my game)

!$Gate1

!$Gate2

If the Forum Wizards like Shaz or Archeia say that posting these are against the forum rules for whatever reason, I'll take this post down as soon as I can.
Terms of Use
Credit would be nice, but not necessary (seeing as I'm just enlarging the RTP Tilesets, as opposed to making them from scratch). However, it is worth noting that unless you've bought a copy of VX Ace and the agreement that comes with it, then it isn't legal to use these. If you have VX Ace already, you're fine, but otherwise I'd advise not using these until you do.
