I can't access the http://users2.tt-forums.net/ttdur/ttdur.htm%A0%A0.
I know the grfcrawler (it is good) , but not always point to the grf that works with OTTD.
I solved the problem with the resolution , I set the resolution to 640x480 (or something like that--the last one) and full screen.
I want a collection of grf set that work together well in OTTD 05.1 RC2 and do that :

1. renew the town buildings
2. new industry
3.to do all the above in tropical (if possible)

I used UKrenewal set and I want to use DBset but in the readme file from that one I saw that have some limitation.

Thank you for all your good advice.
