What are you trying to do?
What is the problem with Famicom Jump II?
There is a note about the game here: https://www.nesdev.org/wiki/INES_Mapper_153
When booting with WRAM filled with zeroes, Famicom Jump II will freeze with a black screen. Simply soft-resetting the console will then always run the game properly unless WRAM is zeroed out again

@paulb-nl Yeah, I have found the problem.
Whatever I have done with RAM initiation, the ROM of "Famicom Jump II - Saikyou no 7 Nin (J) [!].nes" will not work.
I think the core is not done with any other special handling.
Then, I use "Famicom Jump II - Saikyou no 7 Nin (J).nes" without [!] , it works.
Could you explain what is the difference between [!] and no-[!]? and [hFFE]? [a1]? [b1]? [o1]?
Thank you very much.
from nes_mister.
[!] means verified good (header can still be wrong) , [a1] is alternate I think, [b1] bad, [o1] over (too big).
I think the ROMs that are not working are set to the wrong mapper number in their header. You should check it.

@paulb-nl Oh, I see.
I check the header of [!] ROM, which is ines[6]=0x02 and ines[7]= 0x10. The header is wrong.
But I don't know this difference, wast my time to debug...bad ROM.
Moreover, what's that meaning of [hFFE] ?
Thank you very much.
