Here's a small app called n4ru Flash Loader, a successor to JaicraB's Loader, I made in a few minutes. It's completely untested as I have no access to a PS3 until Monday and thus may not work at all, so feedback would be appreciated.
Download: n4ru Flash Loader SRC / n4ru Flash Loader PKG File
It uses the SynaPS3 library, even though it only uses 1 function from the library. No harm in self-advertisement for my (baby-stage) library?
Jaicrab's Loader was made when we still had to use peek/poke to remount directories. We now have syscall8 (hermes) and syscall35 (PL3) for remounting directories. This makes things much easier.
This loader is universal and works with both Hermes and PL3. Create a folder called "cfw" on the root of your device and place the "dev_flash" folder inside it. Then create another folder called "cfw" INSIDE your "dev_flash" folder.
It supports CFW on your harddrive, so once you have a "finalized" build of your CFW, just throw it on hdd0 and run the app on start!
Along with mounting your dev_flash, this app will also dismount your cfw the next time you run it.*
It checks for the "cfw" folder on the following devices (in this order, meaning bottom devices take priority):
usb00x (1 through 7)
Source is of course included, and so is a compiled .pkg
*If any part of the app is broken it's probably this.
