Hi, and welcome

Most probably a cart problem. Check if the voltages to your Naomi are correct (5V, 3.3V), and check if you can access the test menu and if you can test the cart.

Also check this thread: http://www.sega-naomi.com/forum/viewtop ... ight=error

There have been reports that if you turn up the +5v too high (over 5.2 v) that you risk damaging the buffer chips.

I have a NAOMI 1 system here for testbed use and have replacement buffers in stock. If the buffers are bad, I can replace them.

what are buffer chips and ill go checck the voltages the cabinet was originally a soul calibur deluxe machine and i took out the game and swaped it for the naomi with the capcom i/o for it i hope i didnt inadvertantly cook it cause of my ignorance (i didnt know about this site till after i hooked it up)

thx for your help i apreciate it

ok i checked the voltages i hope i did it right heres what i got

[] [] [] [] are all ground (black wires)

0 0 0 0

[] [] []

3.31 5.19 11.73

brown red yellow

these reading were taken from the conecter that plugs directly to my naomi from the capcom i/o converter

hope this helps

Turn that 5.19 down to 5.10

Sounds like the buffers are cooked on the cart. They are a bunch of tiny surface mount chips with LOTS of hair like legs on them.

No. The buffer chips are surface mount components and need to be removed and replaced.

ok rj how how can we get them replaced im willing to ship it to u if u can fix it just let me know also is it worth doing or just find another cart as for the power supply it doesnt have adjustments on it would it be inside the casing?
