Frequently Asked Questions

DMB Frequently Asked Questions

 Q:  Am I able to use my old season disks with version 11?

Yes. We have always had a commitment to maintain your investment in season disks purchased from Diamond Mind. Every new version of the game includes a feature that converts season disks from older formats to the format used by the new version.

For version 11, any season disks that are in version 8, 9, or 10 format are automatically converted to the format used for version 11 when you first install them.

NOTE: If you have season disks in formats older than version 8, one option is to use your earlier version of DMB to convert them to version 8 first, then use version 11 to convert them the rest of the way.

We periodically upgrade our older season disks to add new players, add new statistics, add real-life transactions and lineups, and take advantage of new game features. If you own older seasons, you may be eligible for free or discounted upgrades to those seasons. See Season Disk Upgrades for details.

 Q.  What are the system requirements?

By today's standards, the system requirements are quite modest. DMB runs on Windows-compatible computers (including non-Windows computers that are equipped with Windows emulation software or hardware) that are equipped as follows: 

  • Windows95, Windows98, Windows NT 4, Windows XP, Windows 7, Windows 8, and Windows 10.
  • 32 MB of RAM 
  • 256-color monitor (16-bit recommended) at 800 x 600 or higher resolution 
  • any Windows printer (optional, as all reports can be displayed on the screen or saved as plain-text or HTML files) 
  • 30 MB of hard disk space plus a minimum of 2-3 MB for each season disk, which includes the space needed for full year-to-date statistics for all teams and players. You may need as much as 40 MB for a season disk if you turn on all of the options to save game-by-game stats, boxscores, scoresheets, and game logs. An additional 75 MB may be needed if you choose to generate a web site containing all possible reports for a large league. 
  • Internet Explorer version 4 or above (required only to view the extensive Help system that comes with the game) 
  • an active account with an Internet Service Provider (optional, needed only if you want to use the new NetPlay feature to play head-to-head over the internet)

Q. Am I able to play Version 11 over the Internet?

Yes. Built-in support for head-to-head play over the internet is a major feature of version 11. We don't provide access to the internet, however, so you'll need to have an active account with an Internet Service Provider to use this feature. For more information, see NetPlay.

Q. I'm in the middle of a season replay. Can I switch to version 11 before the season is over, and will I lose any information if I do?

Yes, you can upgrade during a season, and with one exception, version 11 converts all of the information compiled by the previous version, including statistics, transactions, injury reports, boxscores and scoresheets.

The exception involves unscheduled league games, which were supported in versions 1 through 7. Because many DMB features are date-based (weather, transaction processing, date-interval-based reports, and so on), it is no longer possible to play unscheduled league games. (You can still play exhibition games outside of a league context.) If you played a season using version 7 or prior without first creating a schedule, the real-life stats and ratings will convert successfully, but you will lose some of the information related to your DMB season in progress.

Q. I'm playing in a league that uses Diamond Mind Baseball. If some managers in our league upgrade to version 11, and some stay with the older version, can we still exchange statistics?

No, it is not possible to transfer stats, rosters and manager profiles between different versions of the game. That means your league needs to decide whether to stay with the older version or have all league members upgrade to version 11 before your next season starts. Your league can convert in mid-season if every league member converts to version 11 at the same time.

Q. What park images are available? Will you be doing park images for old-time stadiums?

Version 11 includes diagrams for all of the parks that have been used since 1972 and a sampling of parks from prior to 1972. We plan to continue adding diagrams for older parks. New park images are made available for free download via our Ballpark Images page.

Q. Is there a downloadable demo version of the game?

Sorry, we don't have a demo version available. We strongly suggest that you review all of the information available in our About the Game section for details on Diamond Mind Baseball

Q. Am I still able to run my emulator to play on the Macintosh?

Yes. Version 11 is a standard Windows application. If you have a Macintosh with hardware or software that enables you to run Windows applications, Version 11 should run on your computer. DMB cannot offer support for any Mac applications.

Pricing, Ordering, Order Processing, Shipping, Replacement Software

Q. How much does version 11 cost?

Version 11 is now available at the new lower price of just $29.95. (Previous owners of any DMB game version, contact DMB Info at for a $5.00 discount code)

Q. What are the shipping options?

We no longer offer "hard" (CD) copies of our products. Our products are sold via download only.

Q. What versions of Diamond Mind Baseball are available and supported?

 Versions 11 and Version 10 are supported.  However, DMB V10 is no longer offered for sale.

Q. Do you offer discounts for large orders?

We offer a 10% discount for orders over $100, a 20% discount on orders over $200, and a 30% discount on orders over $300. These discounts will not apply to specially-price complete sets of season or team collections.

These discounts apply to products for use by a single customer. They do not apply to orders covering more than one person. For example, a league commissioner cannot earn a 30% discount by placing an order for 24 copies of the current Season Disk for league members.

Contact dmb_support@imaginesports to receive your discount code.

Q. Can I download my order immediately from your website?

Yes, the moment you submit your order and your payment has been accepted you can download the products you purchased.

Q. Why does Diamond Mind no longer offer a 30-day money-back guarantee?

We believe Diamond Mind is the most statistically-realistic baseball simulation, and we stand by our products. Because there is no way to "return" digital products such as downloaded software, any refunds are on the honor system. Unfortunately, some individuals started to abuse our 30-day money-back guarantee by downloading hundreds of dollars of software then immediately asking for a refund. As a result, we can no longer offer the money-back guarantee, and all purchases must be final.

Q. How can I view the status of my order?

A: Log in to "My Account" and view your Account Details. This page lists all your orders. Click on the Order# for further details of the order which you are checking.

Q: What if I need help with a product I purchased from you?

All Diamond Mind products are backed by free technical support by email. Contact for technical support.  We no longer offer phone support. 

Q.  I have some old season disks from the PTP days that you have improved. Do I have to buy them again?

Yes, we're afraid so. We do offer special upgrade prices to registered owners of season disks that were purchased directly from Diamond Mind since the company was formed in September, 1995. However, we are unable to do the same for those who bought season disks from PTP or other sources prior to that date.

Q. Can I back up my seasons?

Yes, and we recommend that you save a copy of the file to a CD or Cloud based backup site such as DropBox to provide you with a backup of the file.

Q.  My pc crashed - do I have to buy everything again?

 Yes.  DMB does not use any copy protection so it is easy to make backup copies of your software in case of a future emergency. Additionally, each purchase comes with a specific number of available downloads.  The bottom line is Back up your software!  However, if you wish to purchase replacement software at a discounted rate, contact

Q.  Is my account information secure?

We are committed to protecting your privacy. Diamond  Mind Baseball does not sell, trade or rent your personal information to others. 

Q. Where can I get player pictures to upload?

Due to copyright and trademark laws, we cannot provide pictures that contain player images or team logos or other copyrighted images, nor can we direct you to any repositories or databases of player images that may exist or that DMB customers may have. You may upload any picture or image to represent or symbolize a player, and any such use may be allowable under “Fair Use” and other legal concepts of non-commercial use.  As a commercial entity, however, we cannot provide them.   

Season Database Questions

Q. Do I need to order the Historical Ballpark Database to use your past seasons?

In most cases, no. Every past season includes all of the ballpark information you need to play realistic games with the teams from that season.

The Historical Ballpark Database has two roles. First, if you want to create a fantasy league of your own using some historical parks that you don't already have in your seasons collection, you can import parks from the historical database and use them in your league.

Second, if you wish to use DMB's player-creation feature, you can reference the park effects data in this database so your players will be created on a park-adjusted basis. (That's how we create players.)

Q. Can I play games among teams from different seasons?

Yes, you can do just about anything you want using standard features of the Diamond Mind Baseball game.

When you play an exhibition game, you can choose the teams, the ballpark, and the era from any season that you have installed.

If you want to set up a league using teams, parks, and players from different seasons, you can do that, too. Just open the DMB Organizer window and click on the Import button to gather the things you want into a single database. After you've done that, you can organize those teams into a league and assign home parks to those teams, release all players into free agency and run a draft, generate a new schedule for your league, and so on.

Q. How do park images fit in?

For three reasons, we do not include park images with past seasons.

First, many of the images you need are installed automatically when you install the Diamond Mind Baseball game, and the ones you don't have can be downloaded free of charge from our web site (assuming those images exist).

Second, most parks don't change from year to year, so it would waste space to store the same image over and over again.

Finally, park image files would increase the size of a season file by a factor of ten (e.g. from about 500KB to about 6MB for the 2001 Season).

Q. How do you do park adjustments for combined players?

If a player appeared on more than one team in a given season, we create one player record for each of his teams and one combined record that captures his overall performance for that season. The event table in each of his team-specific records is park-adjusted based on that team's home park. The event table in his combined record is a weighted average of those team-specific event tables, with the weights based on how much he played for each team.

Q. What are your future plans for expanding and/or improving your past seasons collection?

We plan to continue releasing Current Season in December of each year. We also will continue to release Dan Szymborski's ZIPS projection database around the beginning weeks of each season.

A non-profit organization called Retrosheet is doing an amazing job of compiling (and validating) play-by-play data for historical seasons. We used their data to create our 1972 through 1983 Deluxe Past Seasons. Retrosheet recently released data for some seasons from the 1940s to the1970s, and we will convert those seasons from the Classic category to the Deluxe category at some point in the future.

We will continue to work on upgrades to some of our existing Classic Past Seasons, and we will release those upgrades as they are completed.

The addition of new Classic Past Seasons from the pre-1926 period remains a much lower priority. It's clear from our sales records that our customers are much more interested in the years since World War II than they are in older seasons. We always try to spend our time on the projects that we think will provide the most benefit to the most customers, so we're focusing on the other projects just mentioned for the time being.
