+TODO:
+- dip switches and input ports for Gridiron and Tee'd Off
+
+NOTES:
+- Samples MUST be on Memory Region 4
+
+Additional notes (Steph 2002.01.14)
+
+Even if there is NO "screen flipping" for 'tehkanwc' and 'gridiron', there are writes
+to 0xfe60 and 0xfe70 of the main CPU with 00 ...
+
+About 'teedoff' :
+
+The main problem with that game is that it should sometimes jumps into shared memory
+(see 'init_teedoff' function below) depending on a value that is supposed to be
+in the palette RAM !
+
+Palette RAM is reset here (main CPU) :
+
+5D15: ED 57 ld a,i
+5D17: CB FF set 7,a
+5D19: ED 47 ld i,a
+5D1B: AF xor a
+5D1C: 21 00 D8 ld hl,$D800
+5D1F: 01 80 0C ld bc,$0C80
+5D22: 77 ld (hl),a
+5D23: 23 inc hl
+5D24: 0D dec c
+5D25: 20 FB jr nz,$5D22
+5D27: 0E 80 ld c,$80
+5D29: 10 F7 djnz $5D22
+....
+
+Then it is filled here (main CPU) :
+
+5D50: 21 C4 70 ld hl,$70C4
+5D53: 11 00 D8 ld de,$D800
+5D56: 01 00 02 ld bc,$0200
+5D59: ED B0 ldir
+5D5B: 21 C4 72 ld hl,$72C4
+5D5E: 01 00 01 ld bc,$0100
+5D61: ED B0 ldir
+5D63: C9 ret
+
+0x72c4 is in ROM and it's ALWAYS 00 !
+
+Another place where the palette is filled is here (sub CPU) :
+
+16AC: 21 06 1D ld hl,$1D06
+16AF: 11 00 DA ld de,$DA00
+16B2: 01 C0 00 ld bc,$00C0
+16B5: ED B0 ldir
+
+But here again, 0x1d06 is in ROM and it's ALWAYS 00 !
+
+So the "jp z" instruction at 0x0238 of the main CPU will ALWAYS jump
+in shared memory when NO code seems to be written !
+
+TO DO :
+
+ - Check MEMORY_* definitions (too many M?A_NOP areas)
+ - Check sound in all games (too many messages like this in the .log file :
+ 'Warning: sound latch 2 written before being read')
+ - Figure out the controls in 'tehkanwc' (they are told to be better in MAME 0.34)
+ - Figure out the controls in 'teedoff'
+ - Confirm "Difficulty" Dip Switch in 'teedoff'
