			<content:encoded><![CDATA[<p> yay&#8230;<br />
i had some free minutes and wanted to catch up some changes i always wanted to make.<br />
and since a friend was hacking around with 32bit ARM opcodes using stupid<br />
&#8220;.dd E1234567&#8243;-opcodes, i knew its time to fix this. :)</p>
<p>it took some hmm 10 hours to implement nearly(!) the whole ARM32 instruction set.<br />
now you can code like this:</p>
<blockquote><p>.sub useless<br />
.org 0xDEAD1000<br />
.inj 0&#215;00001000<br />
.imp some_call 0xDEAD0100<br />
.code 32</p>
<p>MOVCSS R0, 0xDE000000<br />
@loop:<br />
ADDCS R0, R0, 0x00AD0000<br />
TST R0, R0 LSR 2<br />
BEQ @loop<br />
BL @some_call</p>
<p>.end</p></blockquote>
<p>this example would  inject the generated ARM32-code at offset 0&#215;1000 into the loaded file,<br />
doing some nonsense-operations and after that it will call the function &#8216;some_call&#8217; at address 0xDEAD0100.<br />
since the code is told to be at 0xDEAD1000 (the &#8216;.org 0xDEAD1000&#8242;), the BL will automatically<br />
get calculated to jump about 0x0E00 bytes backwards, where the function &#8216;some_call&#8217; is said to be.</p>
<p>now its not just useful for hacking firmwares, but also very good for crack..erh customizing e.g. symbian apps.</p>
<p>just one note&#8230;<br />
ARMada sometimes crashes when typing too long. i dont know why &#8211; that happens during the GUI update,<br />
but i really cannot figure out why. but simply use a notepad to code in a clean style, then copy paste it into ARMada ;)<br />
i will try to fix in an upcoming release in which i will also include the last two missing opcodes (coprocessor data and register transfers)</p>
<p>to download, click Projects-&gt;ARMada</p>
