SMBX2pal is a preview build of SMBX2b4, with a mostly complete feature-set, that’s a little rough around the edges. Wait… the SMBX2mx3 build was already that, so what changed?
The SMBX2 MAGLX3 PAL release addresses various issues found within the basic MAGLX3 build. It’s also the version that will be used by the judges for judging the levels of the contest. If you are a participant and worry that your level has become unbeatable in the process: Don’t worry! We took care of that ahead of time. All the levels work as intended!
The specifications of the software can be found in the slightly-updated handbook included in the download. You can download SMBX2pal here. An elaborate list of updates can be found here. Please report any bugs you find either on the SMBX forums topic or directly in the codehaus discord server. Thank you and please enjoy!
