Hi Erel,

I'm trying to read some data from a game (like speed, rpm, etc) and then send to a remote server.

Hi dilettante,

I'm not doing a hijack, the api provided by developers uses shared memory.

Yes,
that would be nice.
I am trying to implement the same.
CGP, I suppose the you are talking about Falcon BMS, no ?

Erel,attached, is the h. file used to map the memory addresses.
It would be awesome to implement such a library. Could it be done ?

Hello,
I have found a Library that does that, but i cant use it in B4A or B4J.
Can anyone do a wrapper for it ?
Please :)

Regards
