The mod when it was developed had to use the set physics of SEIV. That meant we needed to have all the ship hull classifications that SEIV standard had as a minimum. Now with 191 we do not.
After you play for a while if you want to adopt the rule set from another game to this mod by all means help yourself. Just please name it something else and include credit for any one elses mod work or images.
Have fun and sorry about the manual editing issue, we all must do it.
