How very thoughtful of you!!
About time someone did an application like this for PSP...The sprite developing community is pretty big too, you know! Very nice & very cool. I hope you don't mind if I modified the script a little bit for myself...I'm currently working with "big boss caracter type" of sprites, the smallest being 122x97...I like this application very much and when it comes to sprites, it's much faster than working with Photoshop, Gimp or Paint on a PC...at least for me.
**Here's a tip for everyone using this application**
It's much faster and more enjoyable if you run Lua player under another homebrew application called IR shell...Not only can you soup up the cursor's speed by setting the PSP to 266mhz or higher, but you can also listen to music while making your sprites. :D
Can't wait to see what you'll write down for the next release.
