GFT-Exploit:Opera Notes

Here's a simple hack for using a modified opera.ini. So far, it seems to work, however it will occasionally pick up the old one if you exit opera and go back in too quickly.

First (one time only) start up opera and then via the shell do a:

cp /tmp/opera_home/opera.ini /mnt/data/Data/arcwelder

And cat/copy this into arcwelder as 'ophack' (chmod 777 isn't necessary as we're on fat32 which doesn't support permissions):

#!/bin/sh
while [ 1 ]
do

        # Wait for /tmp/opera_dir/opera.ini to exist
        while [ ! -e /tmp/opera_home/opera.ini ]
        do
                sleep 1
        done 

        cp /mnt/data/Data/arcwelder/opera.ini /tmp/opera_home/opera.ini

        # Wait for /tmp/opera_dir/opera.ini to disappear
        while [ -e /tmp/opera_home/opera.ini ]
        do
                sleep 1
        done
done

Run this in the background ( /mnt/data/Data/arcwelder/ophack & ). Modify your new opera.ini in Data/arcwelder to your heart's content. The first thing I did was enable the scrollbars (I *still* can't believe they turned them off). It looks like the proxy section is in there already as well.

Cool hack, although it causes the odd reset on my machine.

I tried mounting /usr/opera with write permissions and fiddling around with stuff there, but apart from changing stylesheets, fonts etc the only useful configuration you can do is to delete /usr/opt/opera_dir/urlfilter.ini, then you can browse your filesystem in Opera using url 'file:///' (It's a nice way to read those long config files)

In fact the opera.ini settings seem to be hardcoded into avos, here's a hexdump starting at offset 0x0096d170:

So unfortunately no opera:config, even after deleting urlfilter.ini
