1 month ago Building my own MechaPwn.elf commenting out the logo stuff in drawLogoFrame() allowed me to get past the USB wait screen. (By the way, is the build usually non-working? I had to fix the bin2s stuff and some of the -l flags to get it to build and I ended up with a 5mb executable instead of a 700kb one.)

1 month ago My working branch on this console is at lina-bh/MechaPwn@noimg. Just realised I was working on master instead of LangPwn but oh well

doh, you just disabled the USB support totally. This sounds like very weird issue, ill take a look at it later.

1 month ago not MassCheck, I only put that on a button for testing. It's the graphics calls for drawing the map that I think is where it crashes.

1 month ago Hey, sorry for the delay, I was away for a bit. Same deal as before on my console, I just pulled LangPwn and built it and had the same black screen. Commented out the map screen drawing lines, it runs properly.

Describe the issue
I ran MechaPwn commit 303a7e7 and got an NVM backup, the next time I ran it I backed out of the options to patch for DEX and I reset the console. Now the executable hangs at waiting for USB drive, with whatever drive I try. PAL PS2 discs still boot. I dumped the NVRAM again with PS2Ident and I can see the MechaPwn payload in the hexdump
Ideally I'd like to ask if there is just a quick way to write the NVRAM backup back to the flash so I can get back to a known good state if possible.
