RCO notes

Busy animation

It seems all the versions of system_plugin.rco (not checked fully) contains a page named "page_busy" which purpose is to display an animated icon at top-right corner of the XMB screen

In old firmwares (around 2.17) the "page_busy" animation was made with 2 images composed by an stripe of 30 frames each, "tex_busy.gim" are the main frames displayed on top (29x25 pixels each frame), and "tex_busy_shadow.gim" are the frames of his shadows (32x32 pixels each frame). The sprx crops the frames on runtime and displays them sequentially to create the animation. This animation is commonly knows as the waterdrop animation

There is a second version of the waterdrop animation (around firmwares 2.50 up to 2.80 or so) that works a bit different, the image "tex_busy" have a bigger frame size (32x32 pixels) and his frame order seems to be inverted, also the GIM settings of both images was modifyed from rgba8888 (lossless) to dxt5 (lossy) so are a bit more pixelated

In modern firmwares the waterdrop animation was removed, but the codenames and filenames inside the RCO was repurposed. The XMB represents the busy state with a visual effect generated by rotating the clock hands textures (tex_busy_l.gim and tex_busy_s.gim) at fast speed, and scaling up and down the clock sphere named "tex_busy.gim" (an icon of 36x36 pixels) together with his shadow named "tex_busy_shadow.gim" (an icon of 46x46 pixels)

The way how this 3 different styles used in the busy animation works internally are very different, the sprx had some changes related with this. It doesnt seems to be posible to "port" the old waterdrop animation to the modern firmwares
