Alright thanks, so I played aroudn with theme editor and examined the source for a while, and the only part that seems useful is as follows (in C):
void hook_menu_handler(Button button, CallbackData button_data, EventCode eventCode)
{
if(eventCode == ENTER || eventCode == MOUSECLIC)
{
Config *conf = new_config();
char *filename = "/ThemeEditor.tns";
char *argv[] = {filename};
if (read_config(conf, 1, argv))
{
free_config(conf);
return;
}
if (conf->mode == 2)
conf->current_index = themeEditor(conf->current_index);
else
theme_editor_gui(conf);
write_config(conf);
free_config(conf);
}
}
static int32_t* new_menu = NULL;
void hook_menu ()
{
if(*((int*)HOOK_ADDR) == HOOK_VALUE)
{
int32_t new_menu_[] = {
1, 0xE5, 0xFFFFFFFF, 1, SYST,
2, 0xE7, 0, 0, SYST,
3, 0xEB, 0xFFFFFFFF, 2, SYST,
3, 0x16D, 0xFFFFFFFF, 3, SYST,
1, 0x176, 0xFFFFFFFF, 4, SYST,
1, 0x192, 0xFFFFFFFF, 5, SYST,
1, 0x5E, 0xFFFFFFFF, 6, SYST,
// sentinel 0x42133769 because we can't get absolute addressing in the declaration of a table
1, 0x34, 0x42133769, 0, SYST,
0, 0, 0, 0, 0
};
new_menu = malloc (sizeof (new_menu_));
unsigned i = 0;
unsigned n = sizeof (new_menu_) / sizeof (new_menu_[0]);
for (; i < n; ++i)
if (new_menu_[i] == (int32_t)0xFFFFFFFF)
new_menu[i] = (int32_t)MENU_CALLBACK;
else if (new_menu_[i] == 0x42133769)
new_menu[i] = (int32_t)hook_menu_handler;
else
new_menu[i] = (int32_t)new_menu_[i];
*((int32_t**)HOOK_ADDR) = new_menu;
puts("patched");
nl_set_resident();
}
I understand C fairly well, but I don't see where the code adds the "6: Theme Editor" to the Settings menu.. Any ideas?
