So I'm having a really annoying issue. First Off: I have a SCHP-90006 PS2 Slim and a Bitfunx MX4SIO adapter. I installed FunTuna3.psu on my Memory Card as instructed and updated its OPL to 1.2.0 Beta 1979, which is the only one that worked with my MX4SIO so far. After that, whenever I made changes to OPL's configurations, it would create a OPL folder in the Memory Card's root folder and completely render useless my FunTuna.
After some hours, I realised a way around it, which is by deleting the OPL item from the OSDSYS and moving the ELF file to a folder inside /BOOT (so I created /BOOT/OPL and moved the ELF there), then I went back and recreated the OPL item in the OSDSYS and associated it with the new path for the ELF file. Great! Somehow, it worked!
Now the thing is: After that I created VMC files in the MX4SIO and after restarting the console... FunTuna would be down all over again and I have to do all over (I actually am using another Memory Card as a backup for whenever things work out, then I just use uLaunch.elf to the main one again). Then I tried to at least load the game from my MX4SIO in OPL and not use a VMC or anything... and my FunTuna is down, corrupted, again! Can anybody help me out here? What am I doing wrong?
