I thought so at the beginning, but after lots of inspections, Borti's fix is pretty straightfoward I have checked every single connection of the addon board + the patch wire. No short.

This lead me to these questions :

1. Could this audio fix interfere with this game's behaviour if everything else is working perfect ?
2. What kind of hardware short would make it work with a patched unofficial firmware at 100% and not the official ones ?

My guess is the person who released this unofficial firmware changed something that is more coherent with this specific hardware setup.

I would like to have more people sharing the same trouble describe their setup.

phalanx67 is your sd2snes modded ?

My bet is a PSU issue...

I had several issues on my settings (1chip pal supercic enhanced and a sd2snes revE->revH) until I replaced the 7805 regulator by a 78s05 which supports 2A.


All issues gone!

that would mean both my snes which has different psus have the same problem ? I will test it on a non 1-chip snes to see what happens.

I still believe the secret is in some mysterious code in the patched unofficial firmware

No. The problem is in the sd2snes.... Its power consumption is over higher than a regular cart.

My snes was working perfect with all my carts, even with SMRPG, STARFOX 2 and SF Alpha, but the sd2snes had some issues that were solved with the new regulator.

Hmmm, I'm thinking Jose is probably right.

Archimage are you using the official Nintendo power supply brick per chance or a third party one?  :P

If you are using the official OEM Nintendo power brick do you have any other OEM Nintendo power brick's to test with your SNES Jr. console?
krikzz products I own: SD2SNES, Joyzz, Everdrive GB X7, Everdrive GBA X5, Mega Everdrive X7, Everdrive 64 v3, Everdrive N8, Turbo Everdrive v2, Master Everdrive X7.

the 1chip pal has an official brick and the JR has a third party one but both have the same problem.. I might upgrade the regulator.

But my attention is still focused on the unofficial firmware which means has a code that leads to a more efficient usage of the hardware. If it's true that it's a power issue it would mean the unofficial firmware draws less power.

EDIT : Tested on a third Snes which is non 1-chip, same problem, still hangs on the same spot. Ordered new voltage regulators to see what happens.
