<ul>

<li><p>The bytecode gets written at the reset vector: [0xBFC00000 .. (???)]. No more than 2k instructions tho.</p></li>

<li><p>Execution time limit is 3 sec.</p></li>
|

<li><p>RAM is at [0x80000000 .. 0x80000100]. That's a whopping 256 bytes, just for you !!!</p></li>

<li><p>This thing is not fully implemented !!</p></li>
