If you do NOT have v.2.56 of the Arcade installation, do NOT proceed.
Instead, go here, and apply the four previous updates, and possibly the optional snapshots file: Arcade Update 1/2022. (Updates MUST be applied in sequence) As always, you should perform a backup using your normal PC backup, just in case. (NOT the arcade backup scripts in the installation.)
In the future, you can always just jump to the Arcade Updates category to check whether you may have missed any updates. The version that you currently have, whether console or ext hdd, may be checked at G:\version.txt. I can’t remember, but I think if you have v.2.40, there possibly may be no version.txt. In the console version, it should report the version number while loading, as long as it’s more recent than v.2.40.
Now that that is all over, here is the download link for the latest Arcade Update file: Arcade Update 2.56-2.58.
One note to mention, is that I added a 2 way joystick config for Clowns. By default, if you check the game’s TAB menu, you will notice that Clowns may be set to Paddles. You may have to set that to your system as well. I prefer to take a pic of the settings before I change things on those menus. These 2 and 4 way joystick configs are most useful if you use an 8 way joystick.
This update also adds a funtion to backup a couple critical 3DArcade directories.
