Issues Dumping Galaxian (Japan) for NES

[LNRC]

Hello everyone!

I'm having difficulty dumping the game Galaxian (Japan). I think I just need a few alterations to my mapper settings, but I don't know how to make these changes on my own.

The cart reader correctly identifies my game as Galaxian. However, the given mapper settings don't seem to match what I find in the various online databases linked on the wiki.

This is what I get from the Sanni:
Galaxian (Japan).nes
MAPPER: 0
PRG SIZE: 16K
CHR SIZE: 8K
RAM SIZE: 0K

When I try to read the iNES rom, this is what I receive
CRC32... E5D11921 -> Not found

Looking at NesCartDB, the PRG and CHR sizes are listed differently
https://nescartdb.com/profile/view/1808/galaxian
PRG SIZE: 8K
CHR SIZE: 8K

Currently, I don't see an option to dump any PRG size smaller than 8K, at least for Mapper 0.

Looking at the NES header database, I get even more different information
http://nes.dnsabr.com/entity/view?id=811
PRG SIZE: 16K
CHR SIZE: 0K

I tried changing the CHR size to 0K since that was an option, and these were the results:
CRC32... 6BFE4FF1 -> Not found

Comparing the original dump (PRG 16K/CHR 8K) and the altered CHR dump (PRG 16K/CHR 0K), both files are 1.5x the size of the original rom. The header appears to repeat partway through. However, I'm not sure what portion of the data I need to cut out for my dump to match the original rom.

Please let me know if there's any further information I can provide. I hope someone can help!

NOTE: I have already cleaned this cartridge many times, it works fine on a physical NES, and my cart reader works fine on other cartridges

In the Cart Reader code the smallest size for PRG is 16K so it can't handle games with 8K PRG like Galaxian.
So it dumps: iNES-PRG-PRG-CHR
You need to delete the block from 0x10 to 0x200F.
