What order to put GRFs in grf.cfg file?????

[walpoo]

Hello All, I trust it is in order to post a long question. I have a basic knowledge of the GRFs in TTDLX, but I cannot find a "rule" for what GRF alters or deletes another GRF. Or in other words, what grf must be put after another grf.

I have put here my grf.cfg, in case I have an error. Any help welcome

Thanks in advance, Wayne (aka Walpoo)

Unless otherwise mentioned (in the READMEs), put it in an order that makes sense to you.

You appear to have 2 copies of the BRSet. This may cause problems.
You have both LVv2 and LVv3. This may cause problems.
You have the DBSet twice. This may cause problems.
You appear to have some DOS grfs (usually ones without the trailing W). If so, this will cause problems.
You have 3 copies of P:GS. This will cause problems.
You have TropicSetw.grf, TTRS2w.grf, and USStatsw listed twice. This may cause problems.
You have both TTRSv1 and TTRSv2. This will cause problems.

In general, put complete replacements (eg DBSet[XL], TempSet, TropicSet, ArcticSet, CargoSet, USSet, LV) before small and single-vehicle sets.
