I eventually copied the BIOS files to another folder & pointed retroarch to it via settings.
I did try the ftp route (
youtube.com/watch?v=uCl9zgqb0Jo) (
https://www.mediafire.com/file/bz4uwdj5enqq5om/UniversalFtpServer_1.4.4.0_Debug_Test.zip/file) and was able to connect to my Xbox with Filezilla, but after the internal folders were listed & I clicked on
LOCALFOLDER it threw a 451 error and I could not get any further. I was able to open all other folders though.
I can only assume the latest version (
RetroArch-msvc2019-UWP_x64) has some sort of read / write protection on system folders ?
Seeing as the official LibRetro advice is to put ROMs outside the internal folder structure (
https://gbatemp.net/threads/official-xbox-one-retroarch-thread.518329/page-80#post-9475535) I think I am correct, see video below:
I encountered another problem I have not seen before but was able to fix ..... after playing
Tekken on PSP I then tried a Dreamcast game, it crashed back to Retroarch with the error message "
Failed to load file_path/game_name (during copy read)". Had a browse of the internal folders and seen the following in LocalState:
As we know, there is an internal limit of 2GB. Doing some research I discovered that if a Cache folder is not specified, RetroArch extracts temporary files to the LocalState folder. Since I was loading large game files it was full after loading
Tekken.
After a fresh install, I then designated a Cache folder outside the RetroArch file system via the Directory settings:
I was able to play a PSP game, then a Dreamcast game, and when I checked the LocalState folder there was no temporary copy of either game (there wasnt in the new Cache folder I created either).
However, there is now a quirky behavior I was hoping someone could help me solve ....
Previously (using version
RetroArch-msvc2017-UWP_x64) I was able to play SEGA Naomi arcade games via
flycast emulator with no issues. Using the updated
RetroArch-msvc2019-UWP_x64 I tried to play
Asian Dynamite (asndynmt.zip), it crashed with an error message of "
Core does not support VFS". I then tried to open
Capcom vs SNK (capsnk.zip) and the game played with no issues. Both game files are in the same folder outside the internal xbox folder structure by the way .
Had a browse of the internal folders and in LocalState there was copies of both games (
asndynmt.zip and capsnk.zip). I was able to delete
capsnk.zip straight away but
no matter how many times I tired asndynmt.zip would not delete it took several attempts to delete
asndynmt.zip .
Any ideas why this is happening & how to fix ? All feedback is much appreciated as always !!
