I want to remake 1997 SUPER HIK 8 IN 1 EW-800
Games order in PRG and CHR are :
PRG :
1 HEROES ICE HOCKEY --> STA $6800 | A : D8 : 1101 1000
2 VOLLEY BALL (MENU) ---> STA $6800 | A : C9 : 1100 1001
3 HEROES GOAL 3 --------> STA $6800 | A : EA : 1110 1010
4 BASKET BALL ------------> STA $6800 | A : FB : 1111 1011
5 HEROES FIGHTING -----> STA $6800 | A : CC : 1100 1100
6 DODGE BALL ------------> STA $6800 | A : DD : 1101 1101
7 HEROES STORY ----------> STA $6800 | A : EE : 1110 1110
8 SPORTS MEETING --------> STA $6800 | A : FF : 1111 1111
CHR :
1 VOLLEY BALL (MENU) --> STA $6800 | A : C9 : 1100 1001
2 HEROES ICE HOCKEY --> STA $6800 | A : D8 : 1101 1000
3 HEROES GOAL 3 --------> STA $6800 | A : EA : 1110 1010
4 BASKET BALL ------------> STA $6800 | A : FB : 1111 1011
5 HEROES FIGHTING -----> STA $6800 | A : CC : 1100 1100
6 DODGE BALL ------------> STA $6800 | A : DD : 1101 1101
7 HEROES STORY ----------> STA $6800 | A : EE : 1110 1110
8 SPORTS MEETING --------> STA $6800 | A : FF : 1111 1111
I think multicard mode registers should be like this :
x x P18 x x x P19 P18 P17
x x C18 C17 x C19 C18 x
7-6-5-4-3-2-1-0
[XXXX XPPP]
[XXXC XCCX]
So far I know I need to use these chips :
AT27C080 DIP32 --> PRG
AT27C080 DIP32 --> CHR
AX5202P DIP40 --> MMC3
I have a plan to use some TTL chips in this order :
138 --> 30 --> 174 --> 157
138 --> to check the state of three data line and three address lines
30 --> to check if it really executing STA $6800 and one of valid A value
174 --> to latch signals of Data (or address lines) for A17, A18, A19
157 --> helps menu to run correctly it will have two mode
Any idea?
