Here I will put up all of the oncalc tools that I've written to help with the development of A:P and I think that some of them could be pretty useful if anyone decides to use mainly masked sprites of varying sizes Oh, and everything is written in Axe (source included) The included executable is nostub (use Asm() to run)

Sprite editors
Controls of all editors: 2nd: black, Alpha: gray, MATH: white, x^-1 transparent, Clear: quit, Enter: save sprite
Hex gets stored to OS Str1, 2, 3, etc depending on how many sprites you make per run.
All editors are masked 3 lvl grayscale designed for use with the Pt-Mask() Axe command.
And here is a good explanation of how masked sprites work if you don't know, because they are really cool : http://ourl.ca/4050/105395;topicseen#msg51271

8x8 sprite editor
Edit at 8x zoom
I think this only supports one sprite at a time, sorry
16 bytes per sprite

12x12 sprite editor
Edit at 4x zoom
Supports up to 4 or 5 sprites stored in Str1, Str2, Str3, Str4, etc. : tap enter to save a sprite, press 2nd to continue or any other key to quit.
64 bytes per sprite

16x16 editor
Edit at 4x zoom
Same as the 12x12
64 bytes per sprite

24x24 editor
Requires 1500 free RAM to run
Edit at 2x zoom
Supports 9 'frames' or sprites per running of the editor: intended for use for animations and such
144 bytes per sprite

32x32 editor
Requires 2400 free RAM to run
Same as 24x24, except at 32x32
256 bytes per sprite

thankee sir I knew they'd be useful for somebody

Nice, this should be useful

Are you planning to update the sprite editor located in the dl section with those? (It might be best to put them in one file, though)
