Spaceworld Demo Datamining

Posted by: OldNewComputers

Based on a small datamining tool I wrote for Generation 1, I adapted it to the Spaceworld demo based on some Gen II base stats info from Bulbapedia. I attached a CSV (well, not sure how to attach a file so I just inserted it as code) with the base stats info I've gotten out of the ROM. (No idea if this is the right place to put this topic). While I found tons of stuff on the sprites from the Gen 2 beta, I didn't find the basestats anywhere. Now, here is what I learned about the Pokemon Base Stats data structure from the Gen 2 betas. I've only attached the new Pokemon and I'll also insert the program code.

- Bulbasaur begins at 0x50f10
- The format is largely the same as Generation II
- Each Pokemon is 31 bytes long, instead of 32 bytes like the final game (not sure what is cut out yet, may be egg info or one of the TM flag bytes)

As with your previous program, it doesn't provide anything new, but seems like it was a good coding exercise that could be adapted for a good few necessary scripts in the future. :)

As with your previous program, it doesn't provide anything new, but seems like it was a good coding exercise that could be adapted for a good few necessary scripts in the future. :)


Thanks for your input, you do have a point that the basestats data is found elsewhere and so is the general program, but what necessary scripts are you potentially referring to?

I don't know what they might end up being. I'm just saying it's good to have another technically-minded member interested in contributing.
