The final map_regions is 768 by 468 pixels, map_heights is 1537 by 937. I have changed the descr_terrain file.

I haven't altered map_heights or ground_types so I am certain all cities are in good positions, not so sure yet about ports (as far as I can tell the map_regions does not exactly overlap map_heights, I am working to change that).

I will try a map_features with no rivers etc. tonight. Is there a maximum size map that the game can handle?
Problem one - Yes maximum size for RTW/BI is 510 x 510 map_regions which equals 1021 x 1021 map_heights. Maximum limit is on dimension not area, so your 1537 length is much too long! That will be problem number one.

Problem two - as you haven't mentioned that you spent hours doing it I assume you haven't.. when you re-size map_regions.tga you will have increased the size of the cities and ports as well, they can only be 1 pixel size, so you'd need to edit them back carefully using the surrounding region or sea colour to overwrit e the additional area. (the expansion will have caused problem to map_features as well as rivers can only be 1 pixel wide or CTD, but having black version will fix that for now)

Problem three - if you do, do smaller version but aim at 1021 long map_heights, I think you might find you have problem with the size of the sea in the bottom left corner, too large a sea can CTD the game, to make sure that isn't issue initially you can just put a block of extra land in there in map_heights.tga - it won't need a city on it so don't worry about including it in map_regions, it will just default to nearest regions ownership.

Possible problem four - now you know you can't double the size of the map, if you decide to multiply it up by smaller percentage so it reaches 1021 you need to make sure you are using a resize method that doesn't invent new merged colours around borders between colours. Use nearest neighbour in photoshop or pixel resize in paint shop pro.

Good news one - no having greater than 50 tiles (pixels on map_regions.tga I think) doesn't cause CTD, it might just mess up AI movement a bit.

Good news two - you should find you can now edit your posts here, please try and do that instead of posting multiple times in a row.

Good luck.....
