>you used gens 9c, I couldnt find a 9c version, just test9a.
9a is the latest unofficial release. 9c is still in progress, but you can PM Jyzero (the guy who's coding it, see Gens forum) and he will send you the work in progress. It has a frame advance feature which is wonderful.
>Not only that I dont really know how to use the record functions too well, like re-record and all that. I've never really made a speed run before.

>But 1 thing that bugs me is if you mess up on one part, do you have to redo the whole thing? I just dont know enough about recording in general.
If you mess up on one part and redo it, you will lose everything made after that part. For example if you record levels 1 2 and 3 and find a mistake in the middle of level 2, you will lose the second half of 2 and all of 3.
Last but not least, make a lot of backups of your movie file as you make it. It's easy to accidentally press the wrong button, load an early savestate and erase everything made after that.
Let us know if you need any more help, but check the FAQ first and use the search function on the forum to see if anyone already asked. Good luck.
