MIR2-NET works with Front-End, but since it requires a special EXE you must place the MIR2-NET exe into your Legend of MIR folder, and tell Front-End to use the EXE.
Step by Step:
1. Download the Mir2net exe to your Legend of MIR folder and call it MIR2NET.exe
2. Start Front-End
3. Open Server Settings
4. Choose a space from the list on the left
5. Enter MIR2-NET's IP: 82.137.38.254
6. Click 'Auto-FIll servername'
7. In DAT/EXE replace privatemir.dat with MIR2NET.EXE
8. Click Save, then exit
9. Click MIR2-NET on the Choose Server tab, viola
It doesnt put 'all server exes into one' like you said SCCraig, but by default uses privatemir.dat, which is the same as most pservers... hence why it works a lot. Therefore if a server doesn't work with privatemir.dat you have to download the EXE that works, and add it to frontend manually.
DeadorAlive, uses Privatemir.dat.
Me and Leo are currently working on the next FE, I even managed to get my old ServerSelector intergrated and updated into it (were calling it the '****e' interface lol)
