There was an exploit found in GTA LCS (none patched ver.) that Fanjita use to creat the GTA eLoader go to www.fanjita.org to learn more, throgh the eLoader you can run certin emus and other home brew.
edit_________________
if you buy GTA LCS make sure you buy it used, some gamestop clerks know about the eLoader, so they might kno whitch one you want.
If you still have your 2.0 just downgrade it! Don't bother buying LCS if you still have 2.0, you can downgrade or you can ust the TIFF exploit version of the eLoader, which doesn't require GTA. So if you have a 2.0 DON'T UPGRADE NO MATTER WHAT!!!
