I'm having trouble with my UMK3 board. It was working, but a week or so ago when I went to hook it up, the characters were snowy/grainy in the character select screen. It also crashed on the versus screen and restarted. I ran a board test and it came up that U54 and U63 were bad. I took them out and ran them on my reader and they came up a bad read there too (not bad data, bad chips). These chips were AMD27C040-150 and TI 27C040-10.
So I tried flashing the mame files um310u54 and um310u63 onto TI 27C040-12s. The board would not boot up at all. The DS1 light is now solid when it wasn't before. I thought maybe it was because I put 12s instead of 10s, but after flashing the same files onto known good 10s, it still does the same thing.
Am I flashing the wrong files? Is there something else I should test? I paid too much money for this board to begin with and now to not have it working is a pretty big bummer. Let me know and thanks in advance.
