Prog 100 error when trying to load sram

had this problem for awhile now but its only now coursing my saves to be wiped when i try to load a rom it will try to load the sram from the sd card and just fail and iv been turning the auto back sram option off in the settings but this has now made some games wipe there current saves

has anybody had this problem and been able to fix it? i had full formated the sd card ect but it only does it once in awhile.....

 

card reformat should help. try to set 32Kbyte cluster size while formatting, and use windows machine for card setup

 

done done and done but im still having this strange prog 100 error when i try and load a new rom from time to time this has only really started since i updated to OS 33 but in the mean time i can just manually save my sram files and hope in the future it gets fixed

thanks for the reply

 

i wonder if cart make save files inside of SED/SAVE folder, or cart make save files in root dir?

 

saves are going to the right place EDMD/SAVE and lucky enough i i found that manually loading my beyond oasis save up worked and i got that to work again but not mega man sadly.....

 

I´m also experiencing errors with the Auto SRAM Backup since v33...there was no response at all to my thread... :-/

 

try solution from my first message if you have error 100 also. error 100 mean that cart can't find save file in saves folder, it definatelly some damage of fat or card was formated by some weird device, like digital cam, or, sometimes, it may just a linux machine. i did not seen such problens with my cards, so i still can't understand where the problem. Usually full reformat under windows is helps. also you may try to change fat system from fat16 to fat32, or visa versa

 

Right iv done everything listed to try and fix the problem and still no joy but found out what also could be a possible course and might be worth looking into

when i load games with sram features such as sonic 3 it will auto save a 64kb .srm file ect but what im finding is games with no sram support say micro machines or rocket knight adventures are making sram files of 0kb?

could this be the reason for the error 100?

 

they have 0kb size cuz OS can not find and write anything in those files, so it is consequence of problem

 

But with games with sram support i dont get a error 100 when backing up the .srm file but when playing say sonic 1 then try and load sonic 3 it will fail to back up the sonic 1 .srm file yet that game doesn't have any save support?

as iv stated never had this problem with os 32 and below

 

so just return v32. Anyway v33 and v34 don't have any important updates. I can't fix the problem until i can't reproduce such problem on my test cart

 

Froggydarren nailed it right away. I've got the very exact same problem with the SRAM backup. From time to time the cart wants to build a .srm file from games which don't have any save feature at all... It seems like there is a bug in the save detection algorithm since v33.

 

it happens before flash erase/burning or after?

 

1. Load a new game into the flash. (Game with no save feature)
2. Turn off game.
3. Load another game into the flash.
4. Everdrive recognizes save which shouldn't. Tries to write to the sd card. Error 100.
5. Every other load fails because Everdrive get's error 100 while trying to write to sd card.

To circumvent this i manually created a .sram file to empty the F-RAM and to be able to continue to an other game. There is a file attached in my thread "SRAM broken in V33". Perhaps it helps to find the missing link.

current OS don't try to recognize sram, cuz some games has wrong headers. OS just look if sram content was changed and perform backup in case if something was changed. probably some games may write something in sram area by unknown reasons, but it definately not the reason of error100. may be you have too many files inside of SAVE folder? error100 should happen if you have more than 500 files inside of /EDMD/SAVE folder

 

I'm sorry. I have only 10 files there. This reason can be ruled out...

 

OS v33 and OS v34 don't work for me too... Prog 100 error all the time, no matter what. Creating the folder manually or not...
FAT? I've tried all possible format options available in both Windows XP and Windows 7; no dice.

OS v32 works fine using the same SD.

 

looks like i fixed it. try OS v35

 

nice work man downloading now!!!

 

Super! Gonna test it tonight! Thanks, chap!
