Does the HIB standalone DRM-free version also include the originals?
They are shown in the game menu, but I didn't manage to launch them (I get just black screen and it falls out with a bunch of errors). Let me check how the GOG version packages them. May be HB release just didn't package those games.
UPDATE: I checked. GOG release somehow embeds old games inside, but I don't see them, I guess they are somewhere inside resource files.
UPDATE2: The error is like this:
...parse_option: line 11, 0x87d3700,0x87d3700 = g_joystick_type = 0 (g_joystick_type = 0) len:19
...parse_option: line 12, 0x87d3700,0x87d3700 = g_cfg_rom_path = res/sys/bttricode (g_cfg_rom_path = res/sys/bttricode) len:34
Read: 131072 bytes of ROM
Open card ROM file bards_tale/diskII.prom failed: -1 err:2
UPDATE3: I see there are iibt1.bin iibt2.bin and iibt3.bin which are zip archives. I guess those are original games. These files differ between GOG and HB releases. I tried to put GOG ones instead those shipped with HB, but it fails all the same. Files are password protected, so you can't easily extract them to use with other emulator (whatever that has to be). I guess it's a form of DRM there, hehe :)
