I've got the same "File System error" problem and some games like The king of fighters 98 had a very cracking sound:
My initial situation was:
FW Rev: 0x03f3
FW Build: 0xa324
TOP file build: 0x4796
Menu Build date: Mar 24 2019
Menu build time: 11:24:13
I've udated top and flash together (lastest one) after clearing backup ram and deleting buff file then cleared ram and deleted buff again and updated the menu
From there I got the file System error and cracking sound (tried a couple of MVS boards)
I've solved downgrading ONLY the flash file to 20190402_r1040.zip then udating again to the last one. Maybe the problem is that I skipped an update.
Now everything seems to work even if I need more tests.
I hope it helps
I tried the suggested downgrade/upgrade method and still issues. I do not get the filesystem error anymore, but nearly all the games I still get the Rom error upon booting. There are notably more jumbled characters during the flashing process too. One game that does boot is 2020 Baseball, but as mentioned before, it has about 4-5 columns of white pixels on the far right of the image. It did not do this before.I did flash first, then top, then menu, all individually and separate boots. 100% deleted the buff each time. All three reported correctly. There's other feedback above, so I'll try those suggestions today and report back.what shows the section about? What did you update that made things go wrong? Flash.img? Top? Menu?
i second that - i would reformat the sd card with the SD Memory Card Formatter and the recopy the unzipped sm pack on the cardI have had the best results doing this...
Format, each and every time you change ANYTHING! Do NOT delete and recopy, I don't care if its only a single file, DON'T.
Do not unzip the SM-ROM pack directly to the SD card. Rather unzip it to a folder on the desktop first, then copy the ENTIRE thing to SD card.
Clear the NVRAM of the MVS before even inserting the cart, then again after.
Perhaps its all in my head, and none of this should matter, but I swear it makes a difference. #tinfoilhatenguage
Oh, also remember to check the menu version contained inside your SM ROM pack, you might have a older version.
If you unzipped to the desktop first as I suggested, just replace the menu BEFORE copying the entire package to SD (again don't delete and recopy ANYTHING on the SD card it self).
Not possible, by definition data in the backup RAM don't have a static state. Of course some bytes never vary but most of the problems are due to corrupted values in the variables.
Each time you write to the NVRAM add 2 bytes as a footer which is the checksum of the written data. Fletcher-16...Not possible, by definition data in the backup RAM don't have a static state. Of course some bytes never vary but most of the problems are due to corrupted values in the variables.
Not sure if possible since the BIOS writes data too for bookkeeping and play time.Each time you write to the NVRAM add 2 bytes as a footer which is the checksum of the written data. Fletcher-16...
If the checksum fail, it means that the the NVRAM cannot retain data.
