As started within the "decent hyppo" project (#140) now let's be a bit more specific and focus on this task here. Some HDOS virtualization is already done, however it should be extended for all currently implemented HDOS traps which is something to do with filesystem. Initially, probably the ones used by BASIC65.

HDOS functions used by MEGA65 'closed' ROM

(the original list with ROM syms and IDs are from BitShifter)

ROM NAME hdos func ID Xemu virtualization status
HYV_CHDIR chdir $0C
HYV_OPENDIR opendir $12 hdos_virt_opendir()
HYV_READDIR readdir $14 hdos_virt_readdir()
HYV_CLOSDIR closedir $16 hdos_virt_close_dir_or_file()
HYV_SETNAME setname $2E half-virtualized, since I always need to know the name set, but hyppo should, as well
HYV_FIND_DE findfile $34
HYV_DLOAD loadfile $36 hdos_virt_loadfile(0) argument is base-addr, since the same can be used for attic
HYV_MOUNT_0 d81attach0 $40 hdos_virt_mount(0)
HYV_UNMOUNT d81detach $42
HYV_MOUNT_1 d81attach1 $46 hdos_virt_mount(1)

MEGA65: add HDOS virtualized loadfile func. #331
9b24b98 
At this stage it's primarly useful for using closed-ROM's DLOAD"..",U12
feature, so with HDOS virtualization enabled, it's possible to load a
file outside of a D81 from BASIC65 directly.
