A new version of the Super Mario 64 level editor, Toad's Tool 64, has been released. 0.5.9 beta fixes a couple of bugs. Here's what VL-Tone had to say:
Version 0.5.9b attempts to fix an issue with checksum verification that would happen on Japanese and other asian Windows systems. Opening an already correctly extended ROM should now work on Japanese systems.
Note that this DOESN'T fix the problem with the ROM Extender on Japanese systems. This problem will require a partial rewrite of the app.
The problem with the ROM Extender is from the Binary IO Xtra. This Xtra enables very fast reading and writing abilities to Director MX. It's fast because it loads the binary data in ASCII string variables, instead of converting them to lists variables (arrays). The problem is that on Japanese systems, Director seems to have a different internal representation of string variables, which corrupts the binary data read into those strings. To fix it I'll need to use another Xtra, and read/write large amount of data with some conversion to list variables, and that will make it much slower. I'll probably have to split the program in two version, so that the fast, but less compatible version is still available.
There is also a new version of the SM64 ROM Extender, which you need to use with your SM64 ROM before loading it into the editor.
