Mega Man II SNES (infidelity) on cartridge without any success

[Kayumba]

Hi,
I have ROM of game "Mega Man II SNES (infidelity)" that I tried to program on my Homebrew PCB to play on my SNES without any success.
Someone else tried to do the same and succeeded ?

Game parameters :
16Mbit LoROM / SRAM 0 battery
EPROM used 27C160

Thanks for help

That's not a lot of info for us to help...
What kind of donnor did you use ?
Are you 100% sure of the rewiring (from the EPROM to MaskROM) you have done ?

Some additionnal pictures of your repro would be useful.

Hi Yolt1,
Thanks for your answer.

I using not donnor PCB but my own Homebrew.
My PCB's are all working with other normal official games and normal SNES hacks.
All my game tests with my PCB I do with sockets that allow me to do many tests.
For this game, I programmed three different EPROMS to be sure that problem came not from my programming.
All three eprom's are not working (black screen).

This game are not normal hack, like others SNES hacks games. This game was manually reprogrammed from NES system to SNES.
Here is "Manifest viewer"


When I see "Manifest fewer" , that shows "mask: 0×8000"
Normally that means it's for game's that using SRAM 64k
I maybe wrong but this Hack do not need any SRAM.
So all of my tests that I've done was without SRAM.
Can it cause the problem ?
