Modification of FEXP

Hello guys, i don't know if you guys know about this: http://forums.bwdyeti.com/index.php?showtopic=433

It's a fire emblem battle system written on RMXP by bwdyeti. (Yeah, i love the gameplay of Fire Emblem, but i don't want to use the whole system without any creation). But for now, i'm really confuse @@ Just look at the whole demo, as tsukihime said that before, it's over 20k lines of scripts and really show me how helpless i am...

As for me, i want to make a funny game about school with that script like this:

- The stat are: Strength Attack, Strength Defense, Smart Attack, Smart Defense, ASP (ASP work just like the demo, so it's alright) and a table which show scores of 10 subjects below.

- There are 10 subjects: Math, Chemistry, Physics, Literature, Foreign Language (Smart Subject) and Swimming, Soccer, Basketball, Fencing, Running (Strength Subject).

- The subjects score will be randomized (about this, i can use random variables so the scores table in stat should be showing the variable which i can edit for each characters).

- Here's the main point: Every turn (after 1 player turn and 1 enemy turn), the system will random and show 1 of 10 subjects as a turn subject. If it's a Strength Subject, all attack of that turn will only use Strength Attack and Strength Defense, and vice versa. And, for example, if turn subject is Swimming, all stat will be affect by the subject's scores. If it's 0 score, all stat of that unit will be counted as 0% of the stat. If it's 50, unit stat will be counted as 100%, and if it's 100, unit stat will be counted as 200%. So i should say, 2% of the stat for each 1 subject score.

- Some weapon may damage HP of the user at a cost to use.

- Some weapon can only use at specific terrain.

- Some weapon will do damage to multiple target in an area of effect.

- Each unit can be promoted 3 times, first at lv 5, then 10 and 15 instead of just 10.

Ah, i tried to contact bwdyeti, too. But it's look like they won't support this scripts anymore TT.TT
