You're right Hammy! I just desoldered the key-cus and now cosmo gang play fine! I can also start F/A , add credits but it resets when start button is pushed (i guess it's because of the missing key-cus).
Here are my 2 Nettou! Gekitou! Quiztou rom boards. Both are working fine with original Nettou! Gekitou! Quiztou rom set installed. Both are stuck in self test if i try your hacked rom sets (whatever the game i try, even cosmo gang).
If you want, i can send you a rom board if you want to study...
Hi! Hammy thanks for your work!
I tried to convert Nettou! Gekitou! Quiztou (NA-2 with NA E4M8(B)ROM PCB long board with C365 Keycus) to Fighter and attacker but it doesn't work... The game is stuck on the self test (ram, palette...). I tried with cosmo gang and i'v got the same issue...
Do...
