RBI Baseball / Re: Help with modifying ProYak...

Last post by ProfessorW - 09/18/25, 03:37:58 PM

I forgot. The IP Patches I mentioned were downloaded from this site (use Google Translate)

http://www.ttttom.website/Mayuemp/Famista/Patch/Patch.html

Basically are zips with a lot of IPS patches, including a README in japanese. The description of some patches in the README did not make too much sense to me, but probably the same README file was used in all the packs for all the different FamSta games.

@NoroNoro, I was more interested in what the README says for some of the patches, that was I tried to wrote in the previous post.

Many of them break the game, but a couple of them are interesting: DH, Uniform_94 (including screenshot of this one when applied to the game). I want to test the 2P one, which if I understood the file, allows second player to pause the game.

It would be awesome to modify some of the famista games with RBI rosters. I can't recall which game it is but it has a box showing the batters statistics for game

Welcome ProfessorW and NoroNoro, who (I think) is our first Japanese member! Do not worry about your English, we understood you 100% and if there are any mistakes we will help you.

Any sort of work on FamSta is certainly welcome, though I have to admit I didn't do much if any work on it back when I studied the code and the the "two player pause" and "pick the same team" ROM hacks.

Thanks for the welcome.

Hello. I am Japanese and I am interested in developing tools and making modifications for Famista (RBI Baseball), and that's why I joined this forum.
However, my English is not very strong, and my understanding of assembly is still limited.

Even so, I would like to learn here and hopefully contribute little by little. Thank you for having me.

-----
I think the paga document you referenced is from the time when the purpose of offsets 0E and 0F was still unknown.
As far as I know, offset 0F is now understood to store the pitcher's pitch distribution data.
So it may not be suitable to use it directly as the 5th character of the player's name.

I'm still learning assembly, so my knowledge is limited, but I hope this helps.


===============================================================

こんにちは。私は日本人で、ファミスタ（RBI Baseball）のツール開発や改造に興味があり、ここに参加しました。
ただし、私は英語があまり得意ではありません。また、アセンブラについてもまだ理解が浅い状態です。

それでも、このフォーラムで学び、少しずつでも貢献できればと思っています。どうぞよろしくお願いします。

-----
参考にされた paga の資料は、オフセット 0E と 0F の用途がまだ不明とされていた頃のものだと思います。
私の理解では、オフセット 0F には投手の投げ分けデータが格納されていることが分かっています。
そのため、選手名の 5 文字目としてそのまま使うのは適切ではないかもしれません。

私はまだアセンブリを勉強中で知識も限られていますが、少しでも参考になれば幸いです。

Well, since my main language is not english (I'm spaniard, living in Mexico), and I understood you quite fine, you can be sure your english is quite fine also.

Thanks for the info about the last byte of pitcher data, I did not know that.

Ok I can probably help here as an RBI editor myself. Here are a couple questions:

1. Do you just want to apply the 5-letter patch or the patch and be able to change the player and team names?
2. Do you have the rom(s) you want to edit?
3. Do you know the hex location for where the names are on the rom?

Please let me know about the above stuff and then I will see what I can do. Thanks!

Thanks for the help. Answering your questions:

1. Yes, I'm currently working on the data, and I want to standarize this rom (and ProYakyuu 87) with the rest of FamSta NES games which uses 5 characters. It would make things a bit easier.
2. Yes, I have them, are from the NoIntro packages. I can post them here if needed.
3.
It's a headered rom:

teamNumber starts at $10.
16 bytes per player, 16 players. So next team starts at $110 and so on, until $A0F.

BOTH HITTERS AND PITCHERS
Byte 00 - playerNumber.
Bytes 01 to 04 - Name.

The structure is quite similar to RBI Baseball, if you need the full structure it I can post it.

Since last byte of pitcher data is already used (as NoroNoro said), the next proposal would be storing the extra data in an empty or unused section in the rom (unfortunately I don't know how to properly identify it) of 160 continuous bytes, one per player, and calculated:

Offset + ((teamNumber * 16) + playerNumber)

Both teamNumber and playerNumber starts counting at 0.

If more info is needed, let me know.

If you have the full rom hex layout that would be amazing please send
Also, please send the roms, just so I know I have the right ones
One question: what does the patch u mentioned earlier do and is the one you posted on your original message the name patch or something else?

My understanding of assembly is still limited, so I'm not sure how much I can do. But if there's anything I can help with, I'll be glad to try.

アセンブラについてもまだ理解が浅いので、どこまでできるか判りませんが、私にできることであればお手伝いさせてください。

Things have changed a bit, around 6 or 7 years, Grupo Multimedios, an important media network here acquired shares of the club (at the same time they lost the economical favor of one of the local soccer teams), and since then, the marketing of the team has improved considerably. You can find caps in supermarkets and flea markets, unconceivable 7 years ago. Those guys literally sell shit in their produced shows, but they're incredibly good at selling them.

Also, they are more worried making money of using the (right now called) Walmart Park for musical shows than the team winning championships.

Pasé dos meses en MTY hace 8 años (creo), cerca de barrio antiguo. Buen pedos los regios... I didn't see the Sultanes though, buddy took me to the Rayados - like you said everyone is soccer crazy there.

I have been living for a few years in a mexican city with the oldest baseball team (Sultanes de Monterrey) still around, since I got sick of local sports media talking only of soccer (football) I got hooked with baseball.

Thanks for the info about offsets $0E and $0F in PY and PY87 pitcher data. For what I understand these values cannot be calculated from real stats like struckouts or ERA, so it's better to not touch them. And also explains some weird behaviour in my earlier experiments, when I modified those offsets thinking it was harmless.

Can I also request your help with some IPs patches I found on another FamSta japanese site? I have trouble understanding what effect some of them have on the game.

I feel relieved that my English was understood, and I'm really glad that a Spaniard like you has such interest in Japanese baseball — thank you for that!

About the offset values $0E and $0F: these are the data used for the COM's pitching variation, and they are referenced randomly.
If the value is $80, the pitcher aims straight down the middle.
If it's $75, he aims at the left corner of home plate, and if it's $8B, he aims at the right corner.

It seems the two values define the "range" of where the COM will randomly aim, and that's how the game expresses each pitcher's characteristics.
However, in many Japanese ROM hacks of "Pro Yakyuu - Family Stadium" and "Pro Yakyuu - Family Stadium '87", these bytes were not well understood, so they were often reused for names or other unrelated purposes.

=======================================================

私の英語が通じて安心しましたし、スペインの方が日本の野球に興味を持ってくれていることにとても感謝しています。ありがとうございます！

オフセット 0E と 0F についてですが、これはCOMが投げ分けを決めるためのデータで、ゲーム中にランダムで参照されます。
仮に、値が $80 のときはど真ん中を狙います。
仮に、$75 の場合はホームベースの左隅を狙い、$8B の場合は右隅を狙います。

この2つの値によってCOMがランダムに投げる範囲が決まり、投手の個性が表現されているようです。
しかし、多くの日本人による 『プロ野球 ファミリースタジアム』 や 『プロ野球 ファミリースタジアム 87年度版』 のハックROMでは、この仕組みが十分に理解されておらず、名前など別の用途に流用されているケースが多いようです。

Forgot to tell.

The values in the table used for names in FamSta roms range from 00 to 57, so don't be surprised when these values appear at the hex location of names.
