// ********************************************************************************
//   Game driver for "ESCAPE KIDS (TM)"  (KONAMI, 1991)
// --------------------------------------------------------------------------------
//
//            This driver was made on the basis of 'src/drivers/vendetta.c' file.
//                                         Driver by OHSAKI Masayuki (2002/08/13)
//
// ********************************************************************************


// ***** NOTES *****
//      -------
//  1) ESCAPE KIDS uses 053246's unknown function. (see video/konamiic.c)
//                   (053246 register #5  UnKnown Bit #5, #3, #2 always set "1")


// ***** On the "error.log" *****
//      --------------------
//  1) "YM2151 Write 00 to undocumented register #xx" (xx=00-1f)
//                Why???

//  2) "xxxx: read from unknown 052109 address yyyy"
//  3) "xxxx: write zz to unknown 052109 address yyyy"
//                These are video/konamiic.c's message.
//                "video/konamiic.c" checks 052109 RAM area access.
//                If accessed over 0x1800 (0x3800), logged 2) or 3) messages.
//                Escape Kids use 0x1800-0x19ff and 0x3800-0x39ff area.


// ***** UnEmulated *****
//      ------------
//  1) 0x3fc0-0x3fcf (052109 RAM area) access (053252 ???)
//  2) 0x7c00 (Banked ROM area) access to data WRITE (???)
//  3) 0x3fda (053248 RAM area) access to data WRITE (Watchdog ???)
