help with software for original R4

Help please, i have an original R4 which has the software v1.18 which i believe was the last one in 2008. I am wanting to add new games onto a different micro sd but dont know what software will work for the newer games (Monopoly) and be compatible with the original R4. Can someone guide me in the right direction please as it is driving me nuts.Thanku. :)

wood R4 is the firmware to use now.
