Final Fantasy Hacktics

Wasn't exactly which board to post this in since it covers such a strange issue. I've been using the same patch I saved since the beginning and everything has been going fine. But just recently, I edited a few more things in said patch, and I'm having a strange problem with my emulator/ISO/keyboard. Occasionally, when I press a key while playing it wont register that I pressed anything. It takes a few more presses before it will register. OR I'll press the key once and it acts as if I'm holding it down. It only started doing this a couple days ago, so my question is simple:

Does anyone have any idea what is happening? Is there a limit to how many edits you can make in a single patch? Could it be a problem with my emulator or ISO? Any help would be much appreciated.

Thanks in advance. 

I've searched the boards but was unable to find anything that clearly answered my questions.

1: How do I make Destroy Sword's Ruins unevadable? I made them 0 CT and free, but I dont know how to make them hit 100%.

2: How can I keep Mighty Sword's attacks stay as they are but be able to cause damage to monsters and humans with no equipment/maintenance? Basically I want them to cause damage even if the target has nothing equipped (monster/human with no equipment in said slot) or has maintenance. Is this possible?

Thank you as always in advance for any help you can offer.   

As the title says, I'm wondering if you can change the unit's portrait using ENTD. I know how to change the sprite and job of a unit in a specific battle but the portrait doesnt change. I replaced one of the generic male squires in the first battle at Gariland Magic City to Zalbag, and everything worked fine except the portrait was still that of the male squire. If its possible to fix this, I would be very thankful to find out how. Thanks!

            Hello, I'm new here and I wasnt sure where to post this question. Here goes; it was years ago that I used Gameshark to mod FFT in order to add the Beoulve family. Using specific codes I was able to replace generic characters with the special ones. How it worked was like this; say I had generic male unit in spot 2 in the formation screen, I was able to replace him with Zalbag, base job of Arc Knight included, without removing Squire from everyone else's Job Wheel. My question is this; can I do the same with FFTPatcher? I want to add the Beoulves again while only changing thier respective base jobs. Also, I was wondering if I can add Balbanes and create a custom job the same way, without sacraficing a generic job? I know this is a long post, but any help would be greatly appreciated. Thanks in advance!

P.S. Sorry again if I posted this in the wrong section.
