nah, im developing for dreamcast, I had my game done in another language but it doesnt work as well as c++ on the dreamcast.

Ummm... Maybe you don't quite get it but... programming is programming. Languages and APIs are just tools. If you can do it in one language, you can do it in another. Making a game where a character can jump can be done in any language I can think of, and in most of them the methods used to make this happen are the same. It's just syntax and idioms that are mostly different. The core structure of it all stays the same.

What I'm really trying to say is learn how to program first. Properly program. I'm not trying to be rude, but really, I think you're getting ahead of yourself.

If you didn't do enough programming to know how to port it when you originally made it... well then I'd say it's time to get your hands dirty in learning how to properly program in some language you would like (starting from the basics). Otherwise it'll never happen.
