Vulcan Venture/Gradius II in MAMEUI .152

I've updated MAMEUI to .152, and after testing my games out, I've come across a weird visual error for Vulcan Venture, otherwise known as Gradius II.
Essentially, whenever I play it, I keep seeing this:
A few more examples here.
Compare that to the images on this page.
Now, I realize that this particular game has been changed lately, which might explain it. Yet, I've tried versions of the ROM from four different sources, and I still get the same problem.
This is the message I get whenever I try to audit the game, and I think it's related:
Code:
vulcan : 785f15.p13 (524288 bytes) - INCORRECT CHECKSUM:
EXPECTED: CRC(5bd239ac) SHA1(9c96f6069d06a1d80c04650ed56bc5e1508db657)
FOUND: CRC(af96aef3)
vulcan : 785f17.p16 (524288 bytes) - INCORRECT CHECKSUM:
EXPECTED: CRC(4e7a7b82) SHA1(520b5ebd400954042d55cf243842a6d6b6d10210)
FOUND: CRC(8fbec1a4)
vulcan : 785f16.p15 (524288 bytes) - INCORRECT CHECKSUM:
EXPECTED: CRC(95c6b8a3) SHA1(0a906af72d08993fd83f23d72ffb919801aa17af)
FOUND: CRC(b858df1f)
vulcan : 785f18.p18 (524288 bytes) - INCORRECT CHECKSUM:
EXPECTED: CRC(3f604e9a) SHA1(c5e0b6f6dd506209e8c07cbae89c821828f488ff)
FOUND: CRC(50d61e38)
So, is anyone else having this problem? I'm not really sure how to correct the checksum, if that is the problem; am I just not using the correct ROM file?

You need the ROMs that were formerly part of the clone "gradius2".

Thank you for the quick replies!
Based on your answers, I replaced the incorrect-checksum files from vulcan.zip, with the analogous files in gradius2.zip. That ended up fixing the problem!

I found this, too....

and found it interesting it even worked. However, I knew it was a problematic set because the UI build I use tells you that roms is bad by [blank] icon type.

Scifi frauds. SF illuminates.
