hi guys,
currently i try to built a Zelda ancient stone tablets cartmod from my german translation. I test some different thing with tsop and Eprom/maskrom games.
Like any of you know it Zelda AST a four week Game which was releases vom St. Giga for BSX. The guys from BSZelda Team has change a lot of things the last 10 years.
After the release of Zelda AST i want to built a cartmod with a 4 way switch.
I uses a DIP Switch with 2 pins.
My question is, what i have to do, to enable and disable the eprom/tsop that i can play week1 (activ) week2,3,4 (inactive)
I have try to set /OE to 5V to set eprom/tsop to inactive).
This works, but if i connect 2 tsop adapter or 2 eproms and set /OE @ eprom1/tsop1 to +5V and eprom2/tsop2 to GND or reverse nothing happen.
Could anyone advice the soldering?
greetz and thanks
