PSX wireless receiver with PIC18F

Can you open the receiver and transmitter boxes and see what components are used ?

yes sir, the receiver was sealed, so i had to hard cut & open with blade...
the RF tx/rx module in both controller & receiver shows MAR105C-1 module.
i tried to find the datasheet but no success.

2.4G module, operating voltage of 1.9V ~ 3.6V, the maximum communication speed of up to 500K, the maximum transmit power is 1dBm, two-way communication, SPI communication pull interface.

I found this image of the MAR105
From that I believe the active component is a
CC2500 or NRF24L01, the crystal speed should tell you which it is.
Both items are hard to use without a code library.
If it is either chip, and you do get them working please let me know.
The NRF24L01 is very cheap and I'd like to use it myself

@ExperimenterUK
thanks dear.
that is what i was thinking of. i searched and found that there is no documentation for this module.
anyways, i shall buy "NRF24L01" and shall change in controller & receiver.
i have another module as well - MAR105P.
Do you think they might be pin compatible?

How will that help ?
Do you have software to use the NRF24L01 ?
i have another module as well - MAR105P.

Sorry I don't know.

@ExperimenterUK
what do you suggest?
i tried contacting the supplier. He told me to search on the internet and nothing else.
i think such modules need accurate timings, which can be analysed with Oscilloscope only. which i don't have .

Start by telling us what you want to achieve?
What exactly is the problem ?
With a lot of effort you might be able to use the transmitter you have with other receivers
but is it worth it ?
Serial bluetooth transmitters and receivers are cheap these days.

You don't need a Oscilloscope
First find out which chip is being used.
What crystal does it use. ?
Then get the data sheet and find out how the chip/ transmitter is controlled.
Then you could,perhaps, understand the full operation of the controller.
