Companies that didn't want their games pirated, that's who. It made sure bootleggers couldn't copy the data and make their own copies. It's crude, but it's worked in a lot of cases.
I'm actually very surprised Team Europe managed to remove the epoxy like this, I didn't think it was possible to remove it with a heat gun without damaging the components (then again I am fairly ignorant on how this stuff works!)

The method was effective or else bootleg versions of the just-for-fun gambling product might have been found/supported by this time in MAME. The current working version of Merit's Dodge City (a newer version) uses a somewhat different hardware arrangement.

GAME( 1988, dodgecty, 0, meritm_crt250, dodgecty, driver_device, 0, ROT0, "Merit", "Dodge City (9131-02)", MACHINE_IMPERFECT_GRAPHICS )
