60 MB? Okay, not that surprised, even DJGPP stuff uses a lot these
days, but it seems overkill for a few MB of data.

I set up DOS 7.1 with Virtualbox because this was more intuitive than
having to restart the comp every time to get around issues.

Yes, of course.

This virtualization **** is kinda cool, the only disappointing thing is the
fact that I can't browse my regular OS from it. The only way I could
copy files to the virtual DOS is making a CD ISO of the directory with
my app and loading from there.

You may be able to use MS NET and/or an FTP server. Check
lazybrowndog's networking guide. (Or if you later try VMware, then try
Eduardo's VMSMOUNT tool.)

This has failed, though. There is no sound and the emulator freezes
the moment I tried to load a game. How do you set color depth on
Virtualbox btw? It says its on 32-bit and needs 16-bit but I don't see
such option anywhere.

Yeah, VBox has quite a few bugs in DOS emulation. If your cpu has VT-X
(which I guess not, sadly), it should work okay though. Too bad more
cpus don't support it.
