Just posted this a while ago over at the frontpage.
It's a screenshot plugin from Fany_rakion, which can do screencaps on VSH, GAME, and POPS.
Changelog ScreenShotPNG Speedy Plugin v0.30:
- The ability to specify a file name.
- A signal that can be displayed after the end took a screenshot.
- Fixed a bug that was captured in a frozen state if the display turns off.
Ah. Also, this plugin has been upgraded to support CFW 5.00 M33-6. The previous version was only compatible up until M33-3.
