Model 2 games stopped working

[sega_mad]

Please help......

First off I lost the blue onscreen color. I stupidly suspected that the video card. I changed out the card and mother board before realizing that it was the monitor.

But now no Model 2 games work. All MAME games run fine. (it's a dedicated SCUD Racing cabinet, so only run about 10 games).

If i try to load the Rom manually it wont run...but if I remove the HDD and install it in my desktop, I can run the Rom (manually) perfectly....WTF!!

Please help....I really miss playing Daytona  

Have included my Model 2 ahk and ini file + mame command file (but I don't belive these are the issue)

Thanks in advance

Solved 

I was testing model 2 games on my computer VGA screen. Turns out that model 2 games wouldn't display (but would work on my desktop)...this was what was tripping me up.

Once I repaired the Arcade screen (just replaced the neck board, as I figured the blue transistor had died)......it all worked perfectly again.

Had me stumped

But happy now, as I can play Daytonaaaaaa!!
