- Super Contra / Thunder Cross
+ Super Contra (GX775) (c) 1988 Konami
+ Thunder Cross (GX873) (c) 1988 Konami
+ Gang Busters (GX878) (c) 1988 Konami
driver by Bryan McPhail, Manuel Abadia
K052591 emulation by Eddie Edwards
+ These three games run on very similar boards, to the extent that
+ Thunder Cross and Gang Busters share the same schematics with
+ callouts ("USED ONLY GX873" or "USED ONLY GX878") to indicate the
+ per-game differences.
+
+ Super Contra uses an external latch for program ROM banking
+ instead of the builtin banking of the Konami custom CPU,
+ and is the only one of the three games that uses sprite shadows.
+
+ Thunder Cross has no 007232 sound chip, and has a 052591 PMC,
+ a programmable custom chip also used by S.P.Y. and Hexion.
+ Here it's used for collision detection.
+
+ Gang Busters uses the 052526 custom CPU instead of 052001, and
+ has slightly different tile ROM addressing.
+
- There was a set in MAME at one time that was given the setname (thndrxja)
which is supposedly a later revision of the japanese set currently in MAME.
No roms were ever sourced for this set, so the GAME macro no longer exists.
