I have set in step.rc:

LitestepDir c:\litestep\


The problem is, from my point of view, that lot of modules uses
LCOpen(NULL) to load the step.rc for processing with LCReadNextConfig,
etc. It worked for me in LS and pLS, so it seems like classical
compatibility problem.

I used steprc parameter that's passed into initModuleEx for opening
step.rc, which worked well in most cases:

FILE *f = LCOpen(steprc);

, but in some older builds of LS or pLS (honestly i don't remember
that exactly) this didn't worked. So I found that easiest and most
compatible way for module is to use LCOpen(NULL).

Since it doesn't work in Retro 0.0.5.10 as I learned in couple of my
modules, I had to go through and change it to:

FILE *f = LCOpen(steprc);
if (!f)
  f = LCOpen(NULL);

Now it works in Retro and in LS, pLS too.

Conclusion: I mean that if step.rc file has been found successfuly by
retro(litestep)-core in the beginning, it should be able to open it
again by calling LCOpen(NULL) in the code.
