What are you playing on? A cab, a supergun?
Sounds like a ground issue or you're shorting something when both are pressed.
No if the game consistently crashes at one spot it would indicate corrupt program code.
Some of the avalaunch CPS2 games have weird issues like this - are you using their code?
If it's Phoenixed, could it be bad chips? Even if it's not Phoenixed, what does the memory test say?
Memory test all ok not phoenixed.. Reset the board.. Still doing 1 or 2 player side. Gonna move it to another machine to try and see if it's the cab but i doubt it. Probably just hunt down another board idk thanks for any input.
Ill reach out to him maybe I'll toss a back up board in and send it out thanks
