How to identify custom firmware

[pegasus2000]

Is there a way to identify that a custom firmware is currently
installed in a PSP ?

I have a program that enables network support on 1.50, but
when the user uses a PSP with custom firmware and 1.50
emulation, the program hangs itself.

So, I must choose the correct initialization procedure, on the
basis of the firmware that is currently installed.

I have tried sceKernelGetDevkitVersion, but when the firmware
is in 1.50 emulation, the code returned is 1.50 and the program
cannot recognize that it is a custom firmware and not a real
1.50 firmware.

Thanks in advance.

from SDK of the past OE/SE firmwares

if user has Homebrew Enabler running

Code: Select all

/**
 * Gets the HEN version
 *
 * @returns - The HEN version
 *
 * HEN D / SE-C :  0x00000400
 */
int sctrlHENGetVersion();

if user has Special Editions | Open Editions and NOT running HEN

Code: Select all

/**
 * Gets the SE/OE version
 *
 * @returns the SE version
 *
 * 3.03 OE-A: 0x00000500
*/
int sctrlSEGetVersion();

Read the file /vsh/etc/version.txt. It is always plain text, and version code is there. If is something different to the 1.50 code, it is probably a custom firmware.
