That's the problem you get when one person keeps all the knowledge to himself.
I would love to mode EM-5/Emergency 16.
sadly, there is no notes, information because the last person to mod the game didn't share any knowledge.
Modding isn't about your ego, or about who is best. Modding should be the community sharing their knowledge
so that people who want to take the time to mod can make the best mods we can.
I might look into modding this if I can find any information as to what is required.
Please, if you ever decide to mod, keep it a community effort and SHARE your work.
I've made mods since the 1990's ( for multiple games, from the sims 2/3, Swat 4, Ghost Recon, Operation Flashpoint,
Sports Car GT, NASCAR 2012, Janes Combat flights , Falcon 4, GTA San Andreas, GTA IV and on and on) and I never held back info.
Your not going to sell your mod, you can't. So holding back info is only hurting the community and make you look like an egomaniac.
