Neo Geo Mini

All jap are FM1J2X1800 so seems it's not the culprit

My issue could be fixed by increasing the deadzone. I really hope such a setting is hidden away somewhere waiting to be discovered.

Hi,

Thanx everybody. There seems to be no pattern indeed.
Only thing i can see is that FM1J1X1800 is not seen succesfully hacked.

Not working (3x):
1x FM1J1X1800 Intl. (Subcon959)
1x FM1J2X1800 Jap. (Tootyuk)
? ? Appearance (TheSnke)

Working (6x):
3x FM1I1X1800 Intl.
3x FM1J2X1800 Jap. (1x MrTea)


@Tootyuk;
I may not be needed to research if the controllers were broken in the process;

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.

So Jacob bought 2 consoles which both died after flashing.. seems to me that cannot be a coincidence.

When this was released I checked videos and The firmware being flashed seemed to be the original Japanese one (same games and menus) which is why I was happy risk running the modified image it on my Japanese model.

With no known source it is a bit of a risk running code we have no idea really where it came from or how to recover if it was bad? Hopefully not too long till we get some answers?

I wouldnt consider mine as broken or non-working. Its definitely still 90% playable. I guess its even stranger that the joystick issue is so variable.. in fact, I really dont understand whats going on :/

It could of course be that there are slightly different controllers in different console production batches with slightly different calibrations.
The manufacturer then has to adjust the calibration setting per batch, and inject a slightly differtent firmware / controller setting into that console batch.


When you overwrite the calibration settings with the hacked firmware (and thus other calibration settings), it could decalibrate because of that.

Yes, that seems logical but the problem is we can see all the files we're flashing and there doesn't appear to be any with joystick calibration data.

There are other partitions that haven't been dumped yet that could contain it, but then how can they be affected when we aren't overwriting those files :/

Imho the best option is to try and get the original fw back.

Does someone know how to contact the author ?

Just a heads up for anyone messing about with this stuff. After tons of successful flashes, I finally had one fail and the mini appears to be bricked as it won't show up on PC anymore and just stays black screen. I think it got to around 40% and flaked out so just be aware this isn't a totally safe method.

That sucks. Any idea what happened ?

Surprised though though the boot loader wasn’t touched by the image.

I havent had time to look into it much. All I know is the flashing failed around 40% and the app no longer detects it. The only thing I edited that particular time was some cover art so it wasnt the files.

When I get a chance I'll try a few more things like drivers etc (Windows did update a couple time that day).

A quick update.. it was actually just the usb cable that died not the console

Managed to re-flash my image with turf masters instead of top players golf..

How do you replace the games on the main screen?

Do you have flashing setup? It's easy to semi brick the console if you don't have a fully compatible usb cable and drivers working properly already.

I can probably come up with a little guide to swap out a game like I did for the Playstation classic.

Yup. I flashed it once already successfully with the iso in the youtube link I posted.

no joystick issue?

Nice to hear! so the risk is only limited to having a decalibrated joystick

I didn't seem to have one, but I have a Japanese mini.

I hope there will be an update because I also have a problem with the joystick

Jap model or international?
