+ Cristaltec "Game Cristal" (MAME bootleg)
+
+ Skeleton driver by R. Belmont, based on taitowlf.c by Ville Linde
+
+ Specs: P3-866, SiS 630 graphics card, SiS 7018 sound, Windows 98, DirectX 8.1.
+
+ Input is via a custom COM1 port JAMMA adaptor.
+
+ The custom emulator is a heavily modified version of MAME32. If you extract the
+ disk image, it's in C:\GH4\GH4.EXE. It's UPX compressed, so unpack it before doing
+ any forensics. The emulator does run on Windows as new as XP Pro SP2 but you can't
+ control it due to the lack of the custom input.
