Causes Error 800200D9 in MHFU (ULES01213), Vita games hang, PSP games disappear

Darthagnon commented 7 months ago

I was struggling for ages with error 800200D9. Full writeup of my issues on reddit.

Issue

PSP games in Adrenaline, or via Adrenaline Bubbles, would fail to launch with error 800200D9. I mainly observed this with MHFU (EU) ULES01213, pretty sure I also saw it with MGS Portable Ops EU. After a game had failed to launch this way, any further attempts to launch Vita games (not Adrenaline/PSP games) would hang on loading; basically the whole PS Vita was hung until reboot.
Sometimes, Adrenaline Bubbles and PSP ISOs for problematic games would disappear. I believe this is related.

Solution

This Russian forum says error 800200D9 is a plugin conflict error. I had minimal PSP plugins enabled (list, though a fair few Vita plugins (list). Lots of people seem to mention the GTA remastered controls plugin as problematic, so I disabled that and all its cousins. Left CheatDeviceRemastered enabled. Issue persisted. Disabled CheatDeviceRemastered, issue gone, games now work perfectly.

Strange that errors caused by CheatDeviceRemastered in PSP-space persist into Vita-space.

This issue is duplicate/related to #2, but is for PS Vita/Adrenaline, not PSP.

Version used: cheatdevice_remastered_v1.0f_29Dec2022

Just noticed there's an update out, I'll try that!

Well, only enable CDR if you want to use it really. There is still no fix, the plugin is simply waay too big. Some games can't handle that :|

Isn't there a way it could check for Game IDs of the various PSP GTA titles and disable itself otherwise?

I remember TheFlow0's GTANativeRes disables itself for GTA games other than Grand Theft Auto: Vice City Stories [ULUS10160] (v3.00) and Grand Theft Auto: Liberty City Stories [ULUS10041] (v3.00), maybe the same technique could disable this plugin for all games other than the ULUS/ULES IDs for compatible GTA?

Take a look at the code.. that's exactly whats already happening. Still, the plugin was loaded to memory at that point already. You can use ARK to load plugins per game but otherwise thats just how plugins work.
