[VITA] JiffyDOS do not work for PsVITA

[16mpx]

I have all the necessary bin files in system vice directory but when I activate JiffyDOS option, nothing happens, vice boots to normal OS, not to JiffyDOS.

I have checked my bin files with the Retroarch Windows version and they are perfectly fine, system boots to JiffyDOS.

Weird, these rows should not be there at all, because those drive ROMs are embedded in the core, and thus they don't need to be searched as files, which does not happen with my systems:

[libretro INFO] DriveROM: 1541-II ROM image not found. Hardware-level 1541-II emulation is not available.
[libretro INFO] DriveROM: 1571 ROM image not found. Hardware-level 1571 emulation is not available.
[libretro INFO] DriveROM: 1581 ROM image not found. Hardware-level 1581 emulation is not available.

Edit: Eh those are repeated later on, meaning that the warning is the same, since it is actually trying to load the JiffyDOS variants already at that point.

And I'm guessing the reason VICE does not find this is because it has a tree letter drive letter:

[libretro ERROR] C64MEM: Couldn't load kernal ROM 'ux0:/data/retroarch/system/vice/JiffyDOS_C64.bin'.

It might be tricky to make it work since those changes can't be tested and confirmed with desktops..

It could be some issue with upper/lower case letters in filenames on Vita. I had issues with that before. Did you transfer the .bin files via FTP? Is the spelling 100% correct including upper and lower case letters?

It is normal file copying with VitaShell cable connected, and I also double checked the spelling including upper and lower cases and it is correct.

Would you please also check the situation if you still have a Vita ?

I tried it on my Vita using latest nightly, and it doesn’t work. You are right, it is not a problem with the files. Core information says they are present. MD5Sums are correct.

My log shows the same errors as yours.

Any idea what version worked before? Pretty sure those VICE side ROM loading things haven't been changed though..

I think worth testing would be:

• If vicerc is read from the same directory (empty dummy file is enough), since it goes through archdep_path_is_relative() like content launching, but sysfile_load() does not seem to
• What happens with first 3.5 commit and last 3.3 commit
