Super Famicom Box confusion

I believe there's still some confusion(even if it's only on my part) regarding the Super Famicom Box ROM-dumps out there.
In a nutshell, I dumped a couple of ROMs, but not all of them.



ROMs inside Super Famicom Box:

• KROM 1, status:undumped(I missed this)

ROMs inside cartridges:

PSS-61:

• ATROM-4S-0, status:dumped
• ATROM-4S-?, status:undumped(alt. version of sfc box menu, owner contacted)
• GROM1-1, status:dumped
• SHVC-FO-1, status:dumped
• SHVC-MK-0, status:dumped
• SHVC-4M-1, status:dumped

PSS-62:

• GROM2-1, status:dumped
• SHVC-2A-1, status:dumped
• SHVC-GC-0, status:dumped

PSS-63:

• GROM3-1, status:dumped
• SHVC-8X-1, status:dumped
• SHVC-T2-1, status:dumped

PSS-64:

• GROM4-1, status:undumped(?)
• SHVC-8X-?, status:?
• SHVC-M4-?, status:?

To clarify: I own a Super Famicom Box with cartridges PSS-61(containing ATROM-4S-0) and PSS-63 and have dumped all contained ROMs except for KROM 1. PSS-64 has not been dumped by me and AFAIK not by anyone else. This cartridge contains a unique GROM and (probably already otherwise dumped) game ROMs.
Judging from Youtube-videos linked above, there appears to be a PSS-61 cartridge out there with a newer menu ROM(probably ATROM-4S-1)
The Super Famicom Box consists of Super Famicom hardware and a yet unspecified system used to superimpose text onto the SFCs video output.

My current understanding is that KROM 1 is the boot-ROM of the latter, ATROM-4S-x is the boot-ROM and menu of the Super Famicom and GROMx-1 contains game-specific data for the superimposing system.

If you own PSS-62 or PSS-64 and want their contents dumped or if you have comments or corrections regarding the above, please contact me at matt [at] dforce3000.de
