I have wrote a hex for the ps3 and im willing to post the hex and the sourcecode written in mikroC but it doesnt use the r1 button it works with a tactile switch and a transistor. works with COD online gameplay also.
Ive also written multimode codes as well just to test my self but what im realy struggling to do is make a R1 button only chip. i can make it so it makes all the RH or LH buttons rapid but what i cannot do is single out a button and its realy doing my head in

i thaught it had something to do with the values of resistors used for the buttons. i couldnt find my multimeter to check them so i found a pic but it says that X [] ^ X and R1+L1 are 10k resistors and R2 + L2 are 7k but i think im gonna go buy a multimeter this weekend and check this for my self.
there is people out there with R1 rapid kits only as there selling them on ebay i bought 1 to try and it does only work on the R1 button and can be installed on ne of the 6 types of wireless ps3 sixaxis controller.
if ne 1 has ne ideas or can help plz post as im starting to loose sleep over it

lol
when i get this working i will post it as open source
