Just got a Mario Bros board and it has no sprites. Tried plugging it into a Popeye and looked good except for no sprites. Any ideas?
 
Bump with more info:

I reburned all the roms and Im still having the exact same problem. Could it be a power problem? I am using a Popeye to test the board and noticed the power supply is different then a DK or DK Jr which most people use to covert Marios. Also reseated all chips. Any suggestions would be helpful. Thanks
 
If you're using a PP-900A in that Popeye test rig, then yes, power is probably the issue. I believe Mario Bros. requires +12v and -5v, and the PP-900A puts out neither.
