If you broke your castlevania cart, why not just use the mask roms from that and put them on the laser invasion board.

it also broke. mmc5 plate curiously not much information. I created several clones only as a hobby, but this is the first time I need it,and it is a strange pcb!

that's is the different about them? varies only in 5 holes, but for example there are 2 "/ CE" in the pcb 1 match, but where the other is connected?

  the pcb also has addresses A18 and A19 and my EPROM has until A17, I should do with A 18 and A19?

What the hell happened to this cart? Ruining a mask ROM isn't an easy task!

That's because the MMC5 supports up to 1MB of PRG, and you'r only using 256KB. Just don't connect anything to those holes.

I'm sorry but I'm a little sceptical. I've seen carts fall and not be damaged at all. I could understand the cart case being cracked, hell even the pcb would be doable...but to crack both mask roms would be really hard. On top of that...3 carts? Nes games are rather sturdy in my experience.

As you know already NES Mask ROMs pinout differ from standard EPROMs so you need to find out the Mask ROM pinout
You can use Mask ROM pinout to find out the pinout of the Mask ROMs to some extent
But for a complete pinout you need do some real work :

MMC5 pinout
Cartridge connector Pinout
Laser Invasion PCB Image

Remove the Mask ROMs from the Laser Invasion PCB
By using a multimeter, Cartridge connector and MMC5 pinout try to find out the Mask ROMs pinout as well as the Laser Invasion PCB hole pinout
Go to alldatasheet.com and search for the datasheet of your favorite EPROMs and find out its pinout
Compare the pinouts of your desired EPROMs with the pinout of the Laser Invasion PCB so that you will know what pin connects to what hole

By the way I want to see the picture of the destroyed cartridge, And don't get the wrong idea
I don't care weather you are a repro maker or not, I just enjoy seeing FC and NES stuff
Also it would be great if you post your finished work and Laser Invasion PCB hole pinout as a reference for future works
