Hello everybody ,
This is my first post at the forum and unfortunately I need to ask you people for help. I've been trying to make a reproduction cartridge of Ninja Commando of Puzzle Bobble. Before I get stigmatized I'd like to tell you that Puzzle Bobble itself was probably a reproduction because, one - boards are from different sets and, two - there were just 3 out of 8 original chips intact. The rest were the UV eproms.
First of all I checked if the board numbers of Ninja Commando matches the numbers of Puzzle Bobble. For that purpose I checked these sites:
https://www.mvs-scans.com/index.php/Main_Page
http://www.jamma-nation-x.com/jammax/mvsboardcodes.html
I picked up a roms dump from other website and checked if the roms numbers matches and what are the sizes of the roms. C1, C2, C3, C4, V1 and P1 were 1 MB so programmed them on M27C800 eproms using MiniPro programmer with the adaptor. Similarly I used M27C400 for V2 which is 0,5 MB and M27C010 for M1 and S1 which are 0,125 MB.
Next I changed the jumper configuration on PRG board according to the picture of Ninja Commando from mvs-scans.com.
Unfortunately the picture I get from the game is totally glitched and screwed . Some graphics are displayed correctly but vast majority is not (even the neogeo logo on the startup). Sound works fine though).
I tried to ruled out all the possible problems so I:
- Checked the tracks with continuity test;
- Tested different jumper configuration;
- Checked the soldering on the pins and reloaded them again;
- Cleaned the connector pins on the boards;
- Cleaned the boards themselves to ensure there is no random wire causing shortage;
- And of course before I unsoldered the Puzzle Bobble chips I checked if the game works (it worked perfectly).
Here is the link to how does the boards look like and what pictures do I get:

At the moment I'm completely clueless what I do wrong. Please help !
Is there something that I missed? I would appreciate any suggestions. Anything that may help really.
Thank you in advance.
