    Copied and pasted from a FB thread i made


    Hey guys, can you help me with this. I have a NeoSD which has worked fine on my Neo29 cab. Went to a meet up with my neosd and sg. When i boot up the cart it wouldnt let me go to the game selection screen.Even with the manual reset. So we didnt get to play anything besides Karnovs Revenge, which isnt a bad thing necessarily. Thought i messed up on a menu option so i changed the name of a folder that causes it to boot up to the game selection screen. Forget what exactly i changed but it fixed it.
    Now i stick it in to my 2 slot big red and im getting the same issue. Do i have to go through this every time i switch cabs/sg's?
    What gives?

    When you can enter the menu (just delete lastgame.cfg from the sd and it will automatically enter there on boot), check in the options menu if you have arcade mode enabled and disable it. If neosd fails to detect a sd card inserted, it won't let you enter the menu.
    Also remember that in a multi slot board, the 'hold start while booting' to enter the neosd menu only works when the neosd slot is first selected by the bios so you might need to hold start and hit the slot switch button a few times for it to work.

    Hi,

    Is there known issues between MV4FS and NeoSD?
    I do not have an OEM bios to test with but tested with Unibios 3.3 & 4 so I am not sure if this post should land in the Unibios thread instead.
    Anyway there is an "Exception Error Handling" after I launch the game. I can access the NeoSD menu, erase/flash a rom w/o issues.
    The 4 slots works well with original carts.
    Not a major issue for me since I mostly run the NeoSD thru a MV1-B but I'd still be interested to fix it.
    Thanks for the help

    There is one known issue I made neodev aware of a week or so ago. No idea if that is related to the issue from your picture though.

    Your backup battery is dead or the backup ram needs to be cleared or both.

    exception error could be down to compatibility/support issues. (program failed to execute)
    if the rom passes CRC32 checkum verifications, it's fine, just down to the devs to account for it's support.
    do a hash check of the dump, if it passes 100%, it down to the devs to account for compatibility.
    if the rom dump FAILS crc, it's one such answer, use the original/no-intro dump that matches verification tables.

    Thanks Raz, I'll wait for the devs to see if they can provide a solution.

    - The battery still retains the settings
    - Did the backup ram clearing
    - None of the roms loaded thru the NeoSD cleared the CRC check in the Unibios. I get double question mark instead of "OK". Could be due to the format of the rom.

    They will probably want more information like what game you had flashed when the error you posted happened etc. Also, why you you have it in SLOT2 and not SLOT1?

    So, the same cart and games work on a mv1b and doesn't on the mv4 ? The issue Raz mentions only happens with some combinations of flashed game and original cart in another slot, so I don't think that applies here.

    I suppose the ?? Instead of OK or NG means that unibios is not recognizing the game

    Yea, normally that would indicate the NGH found is not in the database.

    I've tried with different roms and from each slot (1 to 4). All other slots remained empty.
    I use the rom set from post #44.

    My PSU could be the problem here. Voltage measured at the Jamma edge connector 4.63v. I'll try with another PSU when possible.

    If that's the case then sorry for the false alarm

    That voltage is a bit low. I always have to raise my psu voltage a bit when plugging the 4 slots (and the mv1), they are very power hungry. For neosd, the safe zone is 4.8 and above

    I have been able to do another test with a proper PSU and ensured the voltage at the jamma connector has a stable +5v.
    The error still appears with any roms I flash but this time I can acknowledge and skip by pressing C button then get into the game.
    It is kinda weird but it works.

    not sure if anyone else has this issue but when my Neo SD is flashing it makes a high pitched squealing noise, what could this be, is this normal?
