Well the main two are TWINR ( cracked ) and Cabalrider. Currently TwinR is not working. Cabalrider is working though, you have to download V. 1.06.
I'll give you the website to Cabalrider but there is none for the cracked version of TWINR.
EDITED -
I forgot to mention that this CabalRider is for North America. Not EU, or SG.
