Need help with CRC32 not found for SNES Xenocrisis and MD Romeow and Julicat

Hi everyone,
I have a V5 reader and would like to dump the two mentioned games from the title.
Here are the log files:

OSCR HW5 V14.0

[+] Mega Drive/Genesis

[+] Game Cartridge

bramCheck: 0000

and

[+] SNES/SFC cartridge

Saving to SNES/ROM/XENOCRISIS/36/...
[*******************]
Checksum... 3AD1 -> OK
CRC32... FE5B38F0 -> Not found

What am I supposed to do? Do I need to update e.g. the SNES.txt file manually?
Any help is highly appreciated. Thank you!

Hi.
Yes, both games are currently not into the txt files, so CRC32 check doesn't success.

About Xenocrisis, can you take a picture of the PCB ? I heard there is a special enhancement chip inside, so even if the rom dump is complete, you probably won't be able to run it elsewhere.

For Romeow and Julicat, can you force the rom size to 16 MBits and let us know the CRC32 ?

looks like PCB using « Raspberry Pi SC0914 »

Yeah regarding XenoCrisis, the devs said:
"A framebuffer wouldn't be possible for fullscreen with multiple palettes on a SNES. We had to rework all the sprite/tile/map VRAM allocations, DMA etc for the game to fit within the SNES limits.
C compilers for SNES were also just too limited or flakey - if we had the time for a full assembly rewrite there is no reason why it wouldn't have been feasible.
So we leverage the co-processor to execute the core logic and push the data to fit within those limits. A LOT more time was spent trying to rework the game data to fit within the SNES's VRAM limits."

So in essence I think it is just pumping A/V data to the SNES and reading its controller inputs. I might be a little off, but I've always thought of this release as more of a parlor trick than 'Look what the SNES can do'. Not down on anyone having fun playing it, but it's more of a device than a SNES cart haha.
They also said anti-dumping was a major point of it, cause they didn't like how much the other versions were pirated. I think fans will support them, pirates wouldn't pay anyway, and they'd make more if they could do ROM sales for people that emulate, but what do I know? lol
