    G.I. Joe  (c) 1992 Konami


Change Log
----------

AT070403:

tilemap.h,tilemap.c
- added tilemap_get_transparency_data() for transparency cache manipulation

video\konamiic.c
- added preliminary K056832 tilemap<->linemap switching and tileline code

drivers\gijoe.c
- updated video settings, memory map and irq handler
- added object blitter

video\gijoe.c
- completed K054157 to K056832 migration
- added ground scroll emulation
- fixed sprite and BG priority
- improved shadows and layer alignment


Known Issues
------------

- sprite gaps (K053247 zoom fraction rounding)
- shadow masking (eg. the shadow of Baroness' aircraft should not project on the sky)
