    That's my vid :-)

    To those affected I think at least try to reflash as you have nothing to lose.

    Haha, man, the group of people online who are interested in hacking the mini is incredibly small!

    Probably a good idea to wait to hack it, though, unless you can afford to possibly mess it up and need it fixed later!

    I can confirm if you've flashed it and you have the control/calibration issue using the external pad works

    Have you tried reflashing it see if that fixes it?

    You do know you can already take all the games and emulators you don't want on there (edit the vendor.img with winimg) and put your own games on you want (check my vid)?

    So for now reflashing original firmware is not possible?

    Correct. The only one that can currently be flashed to the system is the hacked Japanese version that was released.

    Ok, big thanks for info ;) I will be tuned to read this thread for progress. I like Neo Geo tittles, currently I only have hacked Neo Geo X nice system with arcade stick and even handheld have microswitches - shame that NG not added it to Mini - but you could search Ben Heck portable mod of Mini witch microswitches by Ben Heck on YouTube.

    In my case, I've flashed several times and it's exactly the same each time. The joystick registers a left push almost without touching it, and it doesn't register a right push until you move it as far as it can go. Makes it very difficult to play a lot of the games. I wonder if the joystick calibration info can even be changed in software, because it doesn't really make any sense for this to happen otherwise.

    Too bad :( yeah doesn't make sense considering the problem is random and seems worse on that other guy video than yours..

    Hi,

    Skipped from my GP32 to hacking my Neo Geo Mini,

    I am now trying to find a pattern for the calibration issue before i take the risk of flashing my INTL appearing mini.

    I watched a few stills on youtube and checked all screenshots from sites where i can read the type number on the back of the systems that claimed to have succesfully hacked the mini.

    I assume that the chinese/foreign video's dont have the calibration issue (i cannot understand chinese but i guess you don't post the result when you system glitches.),
    i see the following (non?) pattern;

    Seemingly working (flashed):
    FM1I1X1800 INTL Appearance
    FM1J2X1800 JP Appearance
    FM1I1X1800 INTL Appearance
    FM1I1X1800 INTL Appearance
    FM1I1X1800 INTL Appearance
    FM1J2X1800 JP Appearance
    ? INTL Appearance
    ? JP Appearance Mr. Tea (Youtube and this forum)

    Not working (flashed):
    ? JP Appearance Tootyuk (Youtube, and this forum)
    ? INTL Appearance Subcon959 (this forum)
    ? ? Appearance TheSnke (this forum)

    I Own (not flashed):
    FM1J1X1800 INTL Appearance

    I deliberately say INTL APPEARANCE since the I of J in after the FM1 might say something about the internals.
    F.e. my system appears INTL but has a J in the code.

    Maybe Tootyuk , Subcon en TheSnke can post their type numbers?

    Interesting but not sure it's the pattern, we need indeed these guys to confirm their codes. Mine is jap and is FM1J2X1800 but I didn't flash it (yet)... Maybe all JAP are FM1J2X1800 ? Need the others to confirm or not

    There's a pic of mine showing the number on page 2 of this thread. I don't think it's a reliable pattern to use.

    Right... Is it possible that guys damaged the stick while removing the bottom of the case? Doubt it but who knows

    Hi,

    @subcon959 Thanx, so you also own a FM1J1X1800. So for now:

    Not working (3x):
    1x FM1J1X1800 Intl.
    1x ?
    1x ?

    Working (5x):
    3x FM1I1X1800 Intl.
    2x FM1J2X1800 Jap.

    Could Tootyuk and TheSnke also have a FM1J1X1800?

    The damange to the stick, no according to this youtube reply and assuming he didn't damage the controller twice:

    Jacob Schaefer 1 week ago
    I am pretty sire it IS anissue with the firmware flash. After flashing my first unit, I went to Gamestop, bought a second unit, tested and confirmed the joystick was working perfectly, immediately flashed it, and the same exact issue manifested. Hopefully this can be fixed in future firmwares, luckily my second one developed it a little less severely, and is still playable, but my first unit is literally unusable at the moment.

    Hi

    Mines a - FM1J2X1800 JPN version

    — Posts automatically merged - Please don't double post! —

    The best test to prove/disprove this would be to have a flashed non working unit and to swap the controller PCB out for a known either flashed or non flashed unit, that way you will know 100% if its the flashing thats caused the controller issue or if we have somehow damaged to the controller pcb (possible)

    I can't speak for other people but I'm pretty sure mine's not a hardware problem. I've had mine open and in bits a lot of the time to do various mods and there has never been any effect on the joystick calibration. I've actually been searching around to see if there are any replacement parts but nothing. If I ever get another one then the first thing I would do is to swap in the control pcb to see what happens.

    As already mentioned, if you plug in a joypad it works as intended, so maybe there is a convoluted way to fix it by taking connections from the usb port. That would be pretty silly though and I'm sure there is probably a way to do it in software that we are unaware of yet.

    Ah too bad. Thansk for the information though guys, now I'm definitely waiting before I flash it, the jap unit is harder to get for me to risk it.

    Mine is FM1J2X1800.

    I'm happy I got mine working with the games I wanted when I did as sadly my laptop has died so I've currently got no pc to use for editing images and roms. Hopefully sorted within the next few weeks though.
