tiikerihai Your snide remarks were both unwelcome and unwarranted.
PPeX support comes from AAU, not Mini. The reason PPX files do not work with Mini in OP "out-of-the-box" is because - as you mentioned - the data file has the .pp2 extension. As soon as you switch from PP2 to PPx in the launcher it "disappears" for obvious reasons...and PPeX support was officially added in 1.6, anyway, whilst the Mini in OP sports 1.5.3. If you have the PPX version of the data file from...wherever..., Mini can detect, read and work with it just fine.
That is the reason I keep advising people all over the thread to switch to MiniPPX, if possible: if you have access to data.ppx, anyway, there is no point in using Mini outside of a very specific reason like a PP2 mod that was never ported over.
The problem I had with the statement of yours I quoted was that Mini actually CAN work with PPX. It is
impractical to achieve, not
impossible.
P.s. How you came to the conclusion that I assumed "both PP2 and PPX cannot be enabled at the same time" from the message you quoted is most certainly beyond me.
