A while ago, I had a pirate cartridge with problems, wich I asked for help here.
The game died for good, so, I'm trying to rebuilt it.
It uses an 1Mbit ROM for the PRG and a 256Kbit ROM for the CHR.
Since I only could get a 2Mbit and a 512Kbit flashes I decided to turn this 4 in 1 on a 8 in 1.
It uses a 74LS74 as a flip flop to change games.
I'll need one more bit to do 8 games switch.
I could only found an 74HC74, would it work fine if I simply duplicate the circuit an cascate it or do I need to do some slight modification with the HC part?
Thanks in advance.
