Received this Japanese version of Liquid Kids for a repair running on a different F2 hardware.
The game was playing fine but hadn’t any sounds.
Amplifier and preamps were good so I started to probe the sound circuit logic.
The Z80 sound cpu ram had some weak signals
After replacing it , the sound was restored.
This game had two problem:
Given the high unreliablity of Taito maskroms I immediately tested the ones marked in red which with no surprice some pins not connected internally
C49-04 restored the glitchy sound and C49-02 fixed the blocky gfx.
Replacements to be used are 27c400 (4mbit eproms with maskroms pinout)
Game 100% fixed
