<br>
the error on the custom-built OSE version high likely comes from<br>
two revision checks we have in our code, specifically in DevHDA.cpp /<br>
hdaLoadExec():<br>
<br>
if (SSMR3HandleRevision(pSSM) >= 116273)<br>
<br>
As the OSE version has a different SVN revision than our official<br>
versions, this code path won't be taken and therefore the loading fails.<br>
<br>
I'll see if I somehow can work around this.<br>
<br>
