Has anyone ever run the RBI arcade version under a Rom Editor to read the player stats similar to the nes stats?

The editor has been down since the server move, but yeah all the stats were sussed out. I never put them on the arcade page, probably should have done that at some point. They gotta be somewhere on these forums in a text file.

Probably in one of the Fantasy RBI draft threads

Here is the nes version of the arcade rom. I'm not sure if there is a way to export the stats but you can manually find them in the hex code.

Did some digging and found it in a thread from 2005.

Thanks everyone for the feedback. I couldn't find what I was looking for, so I spent all day having Chat GPT Reverse engineer the RBI arcade Rom to extract the players stat values.  Attached is a spreadsheet of my findings. Would welcome anyone taking a look and provide any feedback on the ratings.

I should also mention that in my quest to find the arcade attributes the ranges for power, contact speed are different from the nes.  The arcade used 140 as a floor and 255 as the max value for power, the max contact was 220 shared by 4 players, on nes the lower contacts are better, but in arcade the higher the better. max speed was 220 shared by coleman and henderson.

Here are some rankings lists for the players. I included:
POWER
CONTACT
SPEED
CONTACT + POWER COMBO
PITCHERS

I remember the power/contact numbers being the same in arcade as in the NES version, I have a feeling the AI is calculating them in a different way. Maybe it's a two byte number for power instead of one or something like that. Maybe for contact it does a subtraction at some point.

BeefMaster

My recollection is that the data is formatted weird, like some of the bytes appear possibly backward. I think power is stored in a two-byte field, and that might be the deal with the flipped bytes - the original RBI editor, RBI Manager, saw that power numbers appeared out of whack (low-power guys with what looked like high numbers) and called one of the bytes the "groundball attribute" to explain it.

The text file BeastMode posted is correct, and the numbers are in line with the NES.
