Partially I've been busy and partially I just don't know what to say, since only one of your messages was actually a question and not random. On the cry issue, I was at work when I saw it and meant to reply when I got home but forgot.
When it comes to editing cries, you probably won't be able to make it sound exactly like Chikorita. That's because in Gen 1 and 2, each Pokemon doesn't have its own individual cry stored as a sound file. There are a handful of "base cries" and different effects are applied to them. So in data/cries.asm, you will see a bunch of random-looking 3 byte values. These tell the game:
1) Which "base cry" to use
2) How to adjust the pitch
3) How long to stretch the cry out
And that's really it in Gen 1. Gen 2 added more base cries, and added a few other parameters such as setting an Echo and (if I remember correctly) letting you stretch the length and pitch to greater values. So if Chikorita uses a different base cry that wasn't in Gen 1, or some of the other parameters (I don't remember if it does or not) there would not be any simple way to make it sound like Chikorita, as I don't think adding new base cries and such has been very well explained yet.
However, I know that there is a copy of pokered that has Crystal's audio engine in it, and I would assume that it handles cries using the Gen 2 method as a result of that (I would need to double check). I know that base hasn't been updated in a while, but Danny-E 33 said he would be updating it when he got the chance. If you hadn't done too much complicated stuff, you might want to consider using that as a base instead, since you could give the Gen 2 Pokemon their own cries.
Also, keep in mind that in order to add Pokemon past Gen 2 (well technically just to have more than 255 Pokemon) it will take a lot of work, because you would have to change everything that deals with Pokemon IDs to use 2 bytes instead of 1. It's a really tedious process. Shanty Town already has a branch of pokered with that functionality added though. Depending on how outdated your copy of Pokered is, it might or might not be hard to merge it in if you know what you're doing with Git. But those are just things to keep in mind when adding new Pokemon.
