Ookm: Could you change the program that automatically starts HEN C to make it automatically start eLoader 099 when you turn on your psp?

>> taco
BUT eLoader099 didn't patch reboot.bin
when exit eLoader099 it will reboot than back to eLoader099 !!
so don't do that

hi everybody, i'm new in this and i have a question. my psp has the numbers IC 1003 and IC 6001 written under the UMD, so I don't know if it's a TA 082 or not. the FW is 2.71. can i downgrade it? how? thanks

It switches buttons on the PSP. Pretty interesting.

Oh, and 0okm didnt make HENC. That was Dark_Alex. 0okm made the HENC auto boot so that it start when you turn you PSP on. Pretty convenient for me. Thanks for that.

Hi. I also have a "Hen(C) TA-082 2.71" but heard that 0okm has stopped downgrading them :(

Can I use this ButtonHook? Also would it keep the button layout, even during a hard reset?

Hi 0okm.

I have a little problem with You ButtonHook. Compiled prx in archive works good, but when I'll try compile a source code then I have a error :/

That I get when I comilie old or new ver. of ButtonHook:
/usr/local/pspdev/bin/psp-gcc -I usr/local/pspdev/bin/../psp/sdk/include -W -Wa
ll -G0 -fno-pic -mno-abicalls -w -S main.c -o main.s
make: /usr/local/pspdev/bin/psp-gcc: Command not found
make: *** [main.bin] Error 127

I don't have any idea what could be wrong. I don't do any modyfications of source code. Otherwise I don't have problems with compiling "Prx Test" from PSPSDK folder for example.

>> Grizzly_cf
path Error
change path in Makefile
to where your psp-gcc's location

^_^ sometimes i don't know where my mind wanders of to when i try to solve easiest of problems ;)
