This romset comes from a bootleg single board modified Taito F3 System, the only known bootleg/hacked game of this system.
Differences are:
Date in copyright string removed
part of background layer corrupted or missing (as I have seen in arcade).
The audio section was totally modified.
It lacks 68000 and Ensoniq chips,these surely due to availability problems and to hold low production costs.
Some musics are missing,too.
Sound volume regulation output is gained via common analog operational and power ic amplification (LM324 and 1241).
In test mode,digital regulation hasn't effect, due to obvious reason.

update 20080826: redump
