Years ago i estimated vulkan support to be 3-4 man-months of development (just for a poc), I guess that checks out with the knowledge build-up. But back then mesa was way behind, either way, good job. I still remember those dark pre-gl times too...

I wish my time estimates were that accurate, but yeah, about 10-15 hours a day for months. Pre-GL is before me (thankfully).

Am I doing something wrong?

I put my .3ds file into /switch/dekopon/roms/ like Dekopon tells me to, but Library never shows it ("No games found".)

I even thought it was because it was encrypted, so I decrypted it and even put the decryption files in /dekopon/sysdata, and it still isn't being detected.

Very confused.

Hmm.. It should be reading it. Can you put some random 3dsx homebrew in there or try renaming it to .cci to see if it's detected? Does Azahar on PC/Mobile detect the rom?

You are comparing someone who has caused trouble to us (that we still have to deal with) and been completely disrespectful with a project that's respectful and sane.

I'm not going to get caught up in useless drama

its a curse too, normally the rule is to take my time estimate x2

Btw if you join up retronx i'll assign you the patreon role if you want, lots of my people are excited for your stuff (and they make excellent testers) and i'll need to coordinate some vk stuff with you potentially, so hit me up if you want

Like the RetroNX Discord? I just joined there if that's what you meant. More testers is always needed because testing on my own isn't always the most thorough.

Tried a picross game and it worked perfectly. Any way to make both screens the same size in vertical mode like in melonDS?

There's no stretch mode because it tends to look pretty bad. The 3DS has asymmetrically sized screens unlike the DS. The closest there is is the sideways switch vertical mode which is almost like what you want and both screens are larger than in the standard view.
