Does it still exist? If not what is there now for finding scenarios/mods?

These sites are still active..

Thank you!

For mods and some maps and scenarios there is http://cmx1mods.greenasjade.net/mods

You have to register but if you can't find a skin here it probably hasn't been made.

I know this is an old thread but if you find this today is your lucky day. I am a Combat Mission FANATIC. Go here:

https://community.battlefront.com/topic/139429-comprehensive-cmx1-collection/

You will find the links for every mod AND scenario ever MADE for CMBO CMBB AND CMAK. About 14 GIGS worth. Sadly the greenasjade website appears to be no more as of a few days ago. All the mods he had are available in the links you will find from the battlefront link above though. AlternateWars uploaded EVERYTHING to archive.org God bless him. He's my hero. Just go to the battlefont link and you will be directed from there. btw if you want fullscreen 1080p for any of these three games in GOG Galaxy just go to additional executables - Direct X Settings - display mode same as desktop -Presentation fullscreen- Aspect Ratio Correction DISABLED (most important) - Scaling method screen fit. Get to these options by clicking the button that looks like two small arrows to the right of the PLAY button for each game on the GOG Galaxy screen for your game. Simple. You're welcome.

Muchas gracias por esta información. Impresionante trabajo el de compartir todos esos mods y escenarios de un juego que disfrutamos tanto.
