Nice! Goonies 2 was one of the first games I TASed, so it brings back memories. I'm guessing you've seen the run on SDA?
The 17:33 run contains several improvements over the published TAS, so you should carefully watch that run.
I hope you get the hang of using frame advance and all other emulator tools. I really, really, insist that you use frame advance instead of recording at a slow speed. I'll even go so far as to say don't even bother learning TASing at slower speeds, because you won't be using it. With frame advance you have total control of every action taken. It was thanks to frame advance that I could finish the first person sections that fast - I could take my time, carefully testing moving on each frame to find the fastest frame to move.
You should also make sure you are using the frame counter and input display. This way you can easily compare your frame counts to the published run as well as DJ FozzBozz's run.
I have some RAM addresses that should be useful, here.
If you're unfamiliar with RAM watching, there's an article about it here
. Watching RAM addresses when TASing is very useful, so it's something you want to learn after mastering the other tools.
I would be very interested in seeing your progress. You can upload your movie file here.
There are plenty of other articles about TASing here
, perhaps they can be an interesting read. Yeah, this was a lot of info to take in, but really, feel free to send me a PM with any questions you might have.
