About TA-082 SoftDown

encounters some difficulties in the programming :(
diligently to solve :)
Please wait :P

when "TA-082 SoftDown" Release
it can support FW2.71(Original FW2.50)
if your PSP is "Original FW2.50"
feel free update to FW2.71 :)

HowTo add Kernel access under FW2.50/2.60 VSH (eLoader-TIFF)

sample
Download-Link : 25_26_VSH_KA.zip

main.c
add line extern void kernel_ent(u32 Temp);
and write Kernel access in a function
use kernel_ent((u32) &your_function) to call it

// -------------------------------------------
// Kernel access under FW2.50/2.60 VSH
// use Noobz's eLoader(TIFF) 0.9.8
// -------------------------------------------
// Game mode Kernel access by hitchhikr / Neural.
// VSH mode Kernel access by moonlight
// Mod. by 0okm
// -------------------------------------------

drawing, this program performs a series of
operations to load another module, get module
information and execute the module which just
displays a simple message.


<Files>

main.c : Main program
pot.c : Pot drawing routine
pot_main.c : Pot drawing initialization
program
print_msg.c : Program which displays a
message in the debugger

overlay

<Description of Sample>

This program uses the libc shared PRX module to implement the
actions of loading and executing the pot, stars, and skin modules
one at a time from the main program module.

<Files>

Makefile : Make file
main.c : Main program
pot/Makefile : Make file which uses the libc shared PRX
pot/main.c
pot/pot.c
pot/texture.h
skin/Makefile : Make file which uses the libc shared PRX
skin/main.c
skin/skin.h
skin/texture.h
stars/Makefile : Make file which uses the libc shared PRX
stars/main.c
stars/startex.h

<Startup Procedure>

% make -f Makefile

After compilation, the program is started from the debugger.
The executable file name is overlay.prx.

<Controller Operations>

SELECT button : Terminates the program

<Notes>
Processing for the libc shared PRX is switched for the pot, skin,
and stars source programs according to the USE_PRX macro.
