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.

I agree, that the RBI editor and the arcade rom built for the Nestopia is in line with the NES stats, but if you look at the way the arcade rom is built there are differences, for example arcade the only errors are throws, no bops or fielding errors, there is also more carry on pop ups and flys, the line drives are also faster with the super power players imo.

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.

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.

It's terrible but I had to look up Willie McGee and Terry Pendleton. Thought 5 and 6 had both passed years ago.

Is SL the only team in which all players are still alive?

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.

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

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.
