Finally got around to testing my "repaired" everdrive and still I get the v3.4 software error.

So after more testing I have concluded the issue isn't the power supply, I had 19v and 3amp feeding in and still it failed, thanks for the feedback fille1976, so I packed the system away and accepted (for now) that's just how its gonna be. My work around was to power the system on with the everdrive in, on error screen for a few minutes, then quickly power off and on, and it would start working. The reset trick didn't really help, think it must have just been chance when I tried that.

Until yesterday, when I decided there had to be a fix for this, I was thinking this had to be a capacitance issue (it starts working after a short time of power being applied). Looking around I stumbled on this post https://krikzz.com/forum/index.php?topic=6192.0  ??? (thanks Neto)

Investigated the POR for my PAL VA3 board and found this https://www.smspower.org/forums/post73474?highlight=#73474 (thanks MaxWar)

So, I replaced my C1 with a 0.47uf (thats all i had) and I had 50% more success, it even booted in 60hz mode for the first time, previously it never booted in 60hz mode, only 50hz.

I will be ordering some 0.1uf caps asap to test, but wanted to share this asap, maybe you're in a position to test yours now with a 0.1uf.

Some interesting things (for me at least) I'd like to share and may be of use.

So, I've been playing around a little longer as something started acting up again. I may have been too hasty posting my work around (apologies for that)

I have a PAL model 1 with bios v3.4 (only hang-on built in), for the record I did the switched version of the 50/60hz mod.

So far I've discovered if I try booting the cart in 60hz mode I get a 100% failure rate "Software Error", however, booting 60hz to hang-on works fine.

Then I "thought", when I boot the cart in 50hz, the first time it fails, if I turn off then on again with-in 5 seconds it boots fine. If I then turn off the system for more than 5 seconds and then on it fails again. This turns out to be inconsistent.

Just a thought, fille1976, what is the power rating of your power supply? 10v, 9v, 850ma, 1.2a? Mines the standard 9v 850ma, I see the U.S adapter is 9v 1a. Could that be our issue???

Try holding reset while powering on the SMS, that fixed it for me.
