downloads
This page has any downloads you may need for SMB1R. (This runs in SMBX, so download SMBX from the link below first, then put the folder that was in the .zip into the 'worlds' folder). Also, more recent versions tend to appear closer to the bottom.
All of these run on SMBX 1.3, but I will eventually release a version for SMBX 1.4.4 and 2.0.
