-  TODO
+  VT02/VT03 systems go in here
 
-  Add more Famiclone roms here, there should be plenty more dumps of VTxx
-  based systems floating about.
-
-  Make sure that none of the unenhanced sets were actually sold as cartridges
-  instead, there is a lack of information for some of the older dumps and
-  still some dumps in nes.xml that might belong here.
+  - 2KB RAM
+  - VT03 adds alt palette style (not available on VT02?)
 
   NON-bugs (same happens on real hardware)
