Hi guys, recently I modified my naomi to accept netboot and CF, so didn't need to mess with my gd-rom all the time which is pretty cool, so I was in one of those arcade repair week, fixed my sfa3, super buster bros, and Saturday Night Slam Masters.
So i decided to move to my CPS3, my security cart is model D, I burnt the superbios to the 29f that came in the cart, (desolder, erased, blank check, write, verify, resolder).
I have both 64mg RAM on the right and 4 128 from top to bottom on the left, scsi is not the orginal unit but seems compatible, it gets 5.01V, 12.1V on the HDD, PSU is brand new and very stable.
I have the board go trough a GBS 8220 v3, whic works ok with all my jamma goign to my NEC RGB input XM29plus.
So my problem is this,
- I insert the securty cart, no video shows up.. (no video signal msg from the GBS)
- I remove the cart, scramble columns graphics.
- I checked the continuity on the 29f bios legs and seems pretty stable across, I did seem to find a bridge which I'm fixing tomorrow. seems like there is no bridge at all under the magnifier, don't know if they are connected like on the 29f tsop for snes games.
- main IC and processors seems pretty good, no mayor or minor damage across the board.
- what are the symptoms of a busted mother board?
- I bought this already suicide, the cart doesn't have a sticker, it says S.f.3 on a sticker handwritten, so I guess it was one of the SF3 games. don't believe is relevant the type of cart if I already have 4x 128mg and 2x64mg right?
- any other piece of hardware that I can check?
thanks!.
