well, scene-release - pirated software - those groups which brought the nice apps to the poor pupils and students. today the software houses learned their lesson and give out almost full working version for those just want to have aplay with their software
about the lightwave versions on the ftp, just try them step by step, they do all work
(except LW40a - needs dongle - but I added LW40y which works).
ftp -> /~Uploads/emu/Lightwave
I hope you can fix the chip ram issue, so you can have a play with the nice toaster software.
and try the older toaster versions - maybe v2.0 does work with less chip ram.
