Hello guys,
I don't know if this is an ok post because it's about a reproduction cart, and surely hope you guys could gimme some help.
I just made a TSS cart for me using a donor cart that had some busted maskroms. Did it for learning and to grow a little my collection (atm 82 games and only 3 bootlegs/repros). Since it's and expensive cart I give it a shot, and after some days working on it I finally managed to make it run almost flawlessly. Sound is 100%, but as you can see in the pictures I got a strange graphical glitch on the life bars, everything else is ok.
I Used 2 27c322 (C1 and C2), 2 27c800 (C3 and C4), 27c1001 (M1) and 27c010 (S1).
I tried to change some jumpers but it only gets worse. Its not the board (tried others from my own collection), and not the romset (all roms matching CRC).
I really don't know how to fix this.
Here's the page I used as a guide http://www.wolfgangrobel.de/mvs/twinspri.htm
