Relief Pitcher (System 1, prototype) [anonymous, Dutchman2000, SynaMax]

set as draft until the real PROMs are dumped, because the graphics rely on them to look remotely correct. Was dumped from an actual PCB, owner wishes to remain anonymous.

also this is an entirely different game to the 1992 release, which is basically a sequel to this unreleased game

PROMS are correct, but for an earlier LSI board, the structure is similar to other SYS1 games and are NOT corrupted. The correct PROM files for the PS and BS are now in SynaMax's hands.

The PROM located at A7 is the same as all previous dumps, but the latest A5 dump is different (all upper nibbles are now 0xC0). However, when I load the new dumps to MAME, we still get corruption, though it does look slightly different than what I saw previously.

Thanks to Dutchman, the proper PROMs have been recovered. We'll wait for Haze to return so the inputs can be implemented.

I've added the correct PROMs.

I don't understand why the game hangs on 'please center joystick' though, or stalls in attract mode in a similar batting situation.

It doesn't seem to program the ADC (if it has one) in a way that generates interrupts, but maybe I'm just not understanding the ADC properly. Apparently this used hall-effect joysticks, like Road Runner, but using that hookup doesn't work.

There's no slapstic populated so it isn't a protection issue.

Undrafting for now so the correct ROMset can be merged anyway.
