I have a classic PC i use for retro gaming and i would love gog more if i can buy and get original games! (Some do work outside of DOSBOX on DOS and Windows 9x! But some like Wingcommander III can not!!)

Dual Intel Pentium III 800MHZ
512MB SDRAM PC100
ATi Radeon 9800XT + 2x 3DFX Voodoo 2 12MB SLI PCI
Soundblaster AWE64 32MB + Roland SC-88Pro
120GB HDD EIDE Windows ME Custom Modded DOS/9x + MS-DOS 7.1 (FAT32)
64GB CompactFlash to IDE Card Windows XP SP3 for NT based games (FAT32)
500GB FAT32LBA Modded Storage drive

Games like Blake Stone are OK! :)

GOG's DOS games can be used on real DOS hardware with a bit of tinkering; see Mau1wurf1977's series on Installing GOG.com games. This should work for any DOS game on GOG.

Note that a few classic games on GOG are actually native remakes (as with Raptor: Call of the Shadows 2010 Edition and The Chaos Engine) so you can't get the original DOS files from these versions.

The native Windows games are more problematic since GOG's fixes are intended for XP and later.
