Daemon Tools lite will still load images in windows 10 it just cant use a SCSI virtual drive. Reinstall DTL4 and add only a DT virtual drive. Go to RocketLauncherUI global->settings->virtual drive set use SCSI to false. Also switch any disc based system scsi settings to "use default"
With these settings SSF (sega saturn) and UNZ (fm towns) mount images with DTL4
ePSXe (playstation) requires SCSI and wont work. BUT you can disable virtual drive setting and load images directly. I know this is not the greatest method but all my favorite games loaded just fine
PCSX2 (playstation 2) couldnt mount images but disabling virtual drive worked
disc based systems that dont need mounting:
NEC pc engine cd
turbografx cd
neo geo cd
sega cd
3do
cdi
gamecube
wii
jaguar cd
amiga cd32
dreamcast
so yeah all my systems work except those i ran with Demul (Naomi, Atomiswave). Demul crashes so spectacularly I have to reboot everytime.
And Taito Type X (I am so over setting up that system I dont even feel like troubleshooting it)
Besides having to possibly wait for a new version of Demul I would say Windows 10 is worth the upgrade.
