Summary	09185: pwrshovla: HDD image is corrupted
Description	pwrshovla is described in taitotz.cpp to appear to have "some differences in drive content, but identifies as the same revision, is it just user data changes??". According to mokonaXVI, the disk associated with that (power shovel ver.2.07j.chd, with SHA1 of 05410d4b4972262ef93400b02f21dd17d10b1c5e is actually corrupted, where the SYSROM file has the same corruption as present on raizpinj (subject of this PR: https://github.com/mamedev/mame/pull/13779 ) and high score graphics are missing if the SYSROM is forcibly replaced and then booted on a real hardware. pwrshovl's HDD (pwrshovl.chd, with SHA1 of 360f63b39f645851c513b4644fb40601b9ba1412) is reported to work properly.
