Frequently written memory

Problem

Some variables are written often by the program (and therefore also read soon after they are written), f.e. the position in a racing game

Solution

Patch the position update function. This is done in

daytona2
scud
srally2

This is easier in an emulator that allow memory breakpoints, f.e. model3emu, because that allow finding the function

In ArtMoney setting "Options → General → Freeze time" to the lowest value "1 ms" work, f.e. in srally2, when

• it read the position (on finish) more than 1 ms after writing it

doesn't work when

• it read the position (on finish) less than 1 ms after writing it
• it read the position from a function rather than a variable
