PSP Homebrew developer Bubbletune has released a new version of Slim Waves Patch, which has been appropriately renamed to Slim Colors Patch.
In case you missed the previous release, this app "slim-inizes" your PSP Phat by matching its XMB waves with the Slim's. This version lets you choose among the Slim's background colors as well.
This version is also compatible with the latest firmware update. Here's the changelog from Bubbletune:
Changes:
* Now supports 3.90, 4.01 and 5.00
* Name changed to 'Slim Colors Patch'
* Abandoned full version of the plugin
Instructions:
* Obtain 13-27.bmp(added at the bottom, unzip and flash it!) and flash it to flash0:/vsh/resource. (this file changed in 5.00)
* Copy slim_colors.prx to the seplugins folder and enable it in the recovery.
