I have added VT03/VT09 support to my private build of Nintendulator. Download it
here. It runs all games that EmuVT 1.36 runs, plus a few copy-protected OneBus images that EmuVT cannot run. As far as I know, it is also first in running the VT09 ROMs such as Classic Max Lite and VG Pocket/Mini/Tablet. Furthermore, it emulates the additional sound channels that EmuVT does not emulate. In addition to .NES files, it also runs OneBus .UNF, .BIN and .WXN files natively, as long as they're not copy-protected.
Being still a work-in-progress, VT03 modes are only supported in the actual emulator, not the "Debug->Video" window. Copy-protected OneBus images cannot be run in .BIN or .UNF format, because the copy protection type needs to be specified. The .NES 2.0 header's submapper field is used for that.
Also, do not try to run .WXN files converted to .NES or .BIN format; use the
original .WXN files instead. (If you must run .WXN files converted to .NES, then most Waixing games use Mapper 176, while most other games use mapper 256, submapper 1.)
