A Massive Custom Franchise - Real MLB Players from every Era 178 Batters and 121 Pitchers + Lonnie/cbreezy15 MLB Teams/Logos
By IronMan16Bit
Check out my other MVP Mod to get more details on how I built my players = https://www.mvpmods.com/files/file/12264-a-massive-custom-franchise-real-mlb-players-from-every-era-178-batters-and-121-pitchers/.
I used Lonnie Winter's MLB Teams/Logos along with cbreezy15's MLB Teams/Logos depending on which team logo, alt unis I liked more they both can be downloaded on this site.
Big thanks to them for adding these out here that is SOO much work and detail that would take me twice as much time as they spent to add.
A few notes just to call out a few things I've noticed that could use a little more tweaking/adding:
Seattle only has 3 alt unis Athletics only have 1 alt uni Rangers I changed up the colors a little bit, but another team I think could use a little TLC
Important Notes about my Players:
I wanted the announcer to say everyone's name in the game so I tried to pick from their list of names so someone like Barry Bonds = Barry Bond, etc. I created some extra teams to get a full 32, but every team is a State and mascot of used teams in SMB4. I tried to assign everyone a unique Stadium they're some that repeat as we only have 23 Stadiums; but same Divisions don't have a repeat. Most players have been matched for how they looked in their prime and I tried to match most batting styles/pitching styles, music and batting walk-ups etc are just random. All Players I've added are Age = 18 so they could be used in Franchise files and so I could quickly sort them out when creating them, etc. The Franchise file is meant to be Shuffled Drafted I don't think teams are anywhere close to being balanced! lol. If I was in a grove I would just keep adding in batters or pitchers only to some teams. Every MLB Player should have a Legend/Pro Career linked aka I had to go into existing teams find a Pro Career that kinda matched up year wise and duplicated their profile. It took a long time yes, I have OCD yes.

A Massive Custom Franchise - Real MLB Players from every Era 178 Batters and 121 Pitchers
By IronMan16Bit
The main goal or purpose of this was I just wanted to add in some of the best Baseball players I've grown up with and I wanted to create my own ratings/abilities based on performance/analytics(stats) over a certain period of time to see how different eras of players stack up and so I started my journey...
HUGE disclaimer - I did this for fun probably spent over 500+ hours offline researching, spreadsheeting, Googling and 200+ hour-ish adding/tinkering in game. I didn't think I would ever enjoy something like this as much as I did, but man did I get some immense enjoyment and dopamine spikes partaking, ha. That being said AGAIN this is all just for fun and I tried to rely just on the stats/numbers I've captured and biases aside; SO if you think someone is better than x or if you think this is wrong I understand completely. I'm just trying to share my experience because none of my friends wanna play with me, haha.
What is different this time??
Re-pulled in over 26k rows of data from Fangraphs. Grouped players up by Era (criteria below) and then by Primary POS (Fielding/Arm) and then ranked then with a Precentrank formula based on specific stats (below). Every total was then weighted over Best, Peak 3, Peak 5, Career subsets of data for that Player + Era. What that gave me was a clearer picture of who rose to the top for a specific time period/era. I would say Speed and Junk are still the weakest stat of them all.
Speed because we really don't have a great idea outside of Steals, BsR and Spd of how fast they were. BsR and Spd come from Fangraphs and it tried to come up with a value for how fast that player was it relation to base running, etc.
Junk because it's just a weird stat how can you tell how good their off-speed pitches were? Velocity is a little easier because naturally the harder you throw statistically the more Ks and less Hs you will have. It's already overlapping Velocity and Accuracy and in terms of how well these matched good pitchers I was ok with it.
Eras:
<=1919 = Dead-ball <=1941 = Live-ball <=1960 = Integration <=1980 = Expansion <=2000 = Modern >=2001 = Statcast
Skill Stats:
Batters Power = ISO, HR Rate, SLG and XBH Contact = AVG, K%, BABIP, H/PA Speed = SB, CS, BsR. Spd Fielding = TZ/DRS, FLD, DEF Arm = TZ/DRS, A per POS, CS% (C Only) Pitchers Velocity = K/9, SO, H Junk = K/9, BABIP, FIP Accuracy = FIP, ERA, BB/9
That being said they were all rated and normalized on a scale of 1-99 so I could enter those in as Skill Stats within the game.
This I would say is my best iteration yet; minus the PERKS! The perks were entirely built off making every single one of the batters/pitchers OP no matter what. If this isn't your cup of tea just ignore the perk assignment stuff. But if you do like that kind of stuff it was based on skill stat caps, archetypes and a little research on if the player was clutch, were they feared?, etc.
Archetype Handling - I built some flags to help me bucket players together based on stats.
Batters Elite Bat = >=180 Power + Contact OR Power/Contact >=90 Elite Power = >=90 Elite Contact = >=90 Offensive Athlete = >=240 Power + Contact + Speed Elite Defense = >=180 Fielding + Arm
This created 10 Archetypes and helped me see if everything was coming together properly:
Elite Bat, Offensive Athlete, Elite Defense = Complete Dominators Elite Bat, Elite Power, Elite Contact = Pure Bat Legends Elite Bat, Elite Power = Power Bat Titans Elite Bat, Elite Contact = Contact Bat Masters Elite Bat, Offensive Athlete = Offensive Force Offensive Athlete = Pressure Engine Offensive Athlete, Elite Defense = Dynamic Two-Way Elite Bat, Elite Defense = Two-Way Technician Elite Defense = Defensive Anchor Nothing = Role Player
Pitchers Elite Pitch = >=180 Velocity + Junk OR Velocity/Junk >=90 Elite Velocity = >=90 Elite Junk = >=90 Elite Accuracy = >=90 Elite Arm = >=240 Velocity, Junk, Accuracy
This created 8 Archetypes and 14 Base Identities (mainly for Pitch Arsenals) and helped me see if everything was coming together properly:
Elite Pitch, Elite Arm, Elite Velocity, Elite Junk, Elite Accuracy = Era Aces Elite Pitch, Elite Arm, Elite Velocity, Elite Accuracy = Complete Aces Elite Pitch, Elite Velocity, Elite Arm = Velocity Titans Elite Pitch, Elite Velocity = Velocity Enforcers Elite Arm = Complete Craftsmen Elite Accuracy, Elite Arm = Control Savants Elite Accuracy = Precision Operators Nothing = Craft Veterans
I won't go through all the Base Identities, but I wanted different pitching profiles for arsenals so the best thing was to do was to create a few different profiles for each Archetype and with that I was able to create 23 different Pitching Arsenals I assigned to all my pitchers. The best example of this is I wanted high velo arms to have more fastballs and high junk arms have more off-speed pitches. NOW this did produce pitches that a specific player did not even pitch, but the grumble I have with the game is sometimes you get a SP with 2/3 pitches and that is just not a fun experience imo. Every SP got 5 pitches base, RP got 4 and CP got 3 regardless of what they actually pitched with. That would add on so much more time that I really was just ok with assigning an overall identity to them based on their stats/archetypes. You can easily just not use any of that so there is that.
The perk order I approached everything with, which can easily be changed based on what you consider a better perk.
Batters Power: >=93 - Pow vs RHP, Fastball Hitter, Off-speed Hitter, Bad Ball Hitter >=88 - High/Low/Outside/Inside Pitch, Pow vs LHP >=82 - First Pitch Slayer >=78 - Big Hack Contact: >=93 - Con vs RHP, Fastball Hitter, Off-speed Hitter, Bad Ball Hitter >=88 - High/Low/Outside/Inside Pitch, Con vs LHP >=82 - Mind Gamer >=78 - Little Hack Speed: >=95 - Distractor >=90 - Base Rounder >=85 - Sprinter Defense (Fielding/Arm): >=90 - Cannon Arm >=80 - Dive Wizard >=70 - Magic Hands Utility was assigned based on Archetypes and if they played more than 1 POS. If they played more than 50ish games at a POS I added it as a Secondary POS Perks assigned by lore/theme/stats: Clutch Ace Exterminator RBI Hero Stealer Rally Starter Tough Out Pitchers Velocity: >=90 - Elite (4F, 2F, CF) Junk: >=90 - Elite (CB, SL, CH, SB, FK) Accuracy: >=90 - Composed >=80 - Gets Ahead Perks assigned by lore/theme/stats: Elite Pitch Types K Collector Rally Stopper Clutch Specialist / Reverse Splits Workhorse Durable / Consistent
They're approximately 178 batters and 121 pitchers I pulled in and created in game. I might of missed someone here or there, but I tried to grab the best of every era.
EDIT 1:
I've updated everyone's Chemistry based on their Primary Perks as I wanted a better range of all 5 Chemistry personalities.
Little quirks here and there:
I wanted the announcer to say everyone's name in the game so I tried to pick from their list of names so someone like Barry Bonds = Barry Bond, etc. I created some extra teams to get a full 32, but every team is a State and mascot of used teams in SMB4. I tried to assign everyone a unique Stadium they're some that repeat as we only have 23 Stadiums; but same Divisions don't have a repeat. Most players have been matched for how they looked in their prime and I tried to match most batting styles/pitching styles, music and batting walk-ups etc are just random.

2025 MLB - All Teams, All Players, All Logos, 90 Free Agents
This is for the SMB4 Community!
This is a collection of great MLB logos and Rosters from 2025 of all 30 MLB teams, made by various creators.
I have compiled a lot in order to achieve the best possible result. I have also created one or two logos based on original templates from the internet or/and made some finishing touches to other logos. Overlay technique, so to speak.
I also finished the previously missing 14 rosters with 2025 MLB players according to the specifications of Elder_III. It took me about 200 hours in total as I also created 90 Free Agents, including some of the best 2026 prospects.
It was a huge effort from all who have worked on it so far. Therefore, I would like to expressly thank everyone.
I decided to upload it because the community has been longing for it and I hope no one minds. It is not my intention to upset anyone but to make the community happy. Thank you for your understanding.
I wish everyone a lot of fun with this league.
A BIG THANK YOU goes to
Rocket-man15 aka cbreezy15,

BETA v1.0 Super Mega MLB (2025 Rosters)
By ViiperBoxer
With the 2025 MLB roster ratings made by Reddit user Elder_III and the alot of the uniforms and logos made by Reddit user Rocket-man15. I have spent the time putting everything together and this is just the teams that if the MLB were to make the MLB posteseason 16 teams these would be the teams in the playoffs. The images are what the 16 playoff would look like and the 2025 World Series teams.
I am working on getting the other 14 teams completed as well as some free agents (mostly players that didn't make the rosters) and when the rest of the teams are complete I will be releasing everything on MVP mods I just wanted to get kinda like a teaser out since SMB4 is dead and we'll never see a real Super Mega MLB game hopefully this will scratch that itch.

MLB Legends 20 Team Expansion League
By elderiii
This is an expansion I had made for my own personal usage. Now that there is a way to share custom teams/leagues with others, I decided to upload it here.
This league includes the 8 default Legends teams (and Free Agents), and an additional 12 teams based on real Historical players, for a total of 20 teams in the league. The teams are roughly from these time periods and/or settings.
1800s Negro Leagues Only 1900-1933 1 1900-1933 2 1934-1966 1 1934-1966 2 1965-1985 1985-2005 2000-2020 NPB 1 (Japan) NPB 2 (Japan) Sentimental Favorites (from my youth)
Since the default Legends teams are nearly all from the 1960s-onward, I wanted to add more players from earlier time periods, as well as some more players from recent times. The only rules are that they all be retired players, and that teams be as balanced as possible within the same numerical framework as the default SMB teams have always been. The ratings are all based on Career statistics, NOT on Peak seasons. I used the general Excel equations that I have used in my annual MLB roster releases (which can be found on Reddit each year for the past 9 years). For older players I also relied heavily on OOTP for defense ratings.
I am not good at making uniforms or logos and I just plain don't enjoy that part of the process at all. Feel free to change anything you like. I did have to move teams around to different stadiums than I typically use since I don't want something to break if someone does not have all the stadium dlc. As is, this league only uses default game stadiums.
