Unfortunately it doesn't work. Neither 2000 nor 2003.
But maybe i did it wrong way.
- got my 2000 and 2003 versions nro on sd card, recognized in hbl
- created a folder called "mame2000" and put m2000 compatible .zips (according to that github list). Games such as wwfmania.zip.
- created a folder called "mame2003" and put tekken3.zip, btoads.zip, sfiii3.zip and some more in this folder.
- launched mame2000, tried to launch games (load content → / → sd → switch → mame2000 → wwfmania.zip → load archive → switch crashes with 2162-0002)
- same goes with mame2003.
- i've tried to put mame2000\2003 folders in different paths, but it doesn't work.
Conclusion = doesn't work on real hardware yet.
