Hm, didn’t know about this. Thanks. You can swap the ps1_rom.bin (BIOS) in flash to another PS1 BIOS to completely fix this issue. The game’s problem is due to Sony’s “optimizations” to the internal PS3 BIOS, and Midway’s poor coding of this game.
You can get a perfect 4:3 aspect ratio when...
I see what is going on. When I tested, instead of saving after the first level, I would select continue instead. This command somehow fixes the freeze after saving, but not the continue freeze. Potentially timing with the cdr Pause command will need a greater or lesser change than that bit performs.
Nice find! I tried a good chunk of tests myself but could never make any progress.
It maybe needs something else in tandem with that command, maybe a cmd -1 bit. It crashes mid-game?

EDIT: Seriously, GBATemp likes to only update the thread after I reply. Did not see Ronnie’s post above.
Not too sure.
By the way, PCSX2 has the same exact issue with this game. Maybe that can help the debugging process. We were never able to find a fix for this one. Looking back at my history, this is what I have:
This is all speculation based on debugging from PCSX2. I usually have no idea...
Well, almost all of the config commands have been reversed and documented by kozarovv here: https://www.psdevwiki.com/psp/POPS
This is how we have been cooking the custom configs that are added automatically to the EBOOT when converted with pop-fe.
Yup, it should be set for both PSP and Vita. Command 0xFF bit 13 would have to be ORed into the game’s config, or a config created if there is no config for a game. You can also look at Tekken 2’s config in the current pspconfigs to see exactly how it should look.
That would be great!
Yup, could not have said it any better! Kozarovv reversed that cdda_enabler and cmd 0xFF bit 13 inside of POPS essentially hit the same branch. There is not really any harm in enabling it at all times, but pop-fe can maybe enable this bit for the “Use CDDA, not AT3” checkbox instead to ensure...
I have attached the config that fixes this issue. Please test to make sure everything works fine!
No worries! I believe 99% of PS1 library should be compatible on PSP 6.61/Vita 3.6x when all is said and done.
They should be pretty close. Compatibility may be a bit different in some instances, mainly due to the differences in sound emulation. “POPS for Vita” has added config commands and additional parameters for existing commands that can fix issues that are “unfixable” on PSP (for example, Star...
@wad11656 Yeah, pretty much what @Webardo said. I have just been manually been moving over the reports slowly.
After adding the rest of the entries, it will become very clear which games still need to be fixed, which is pretty nice to visualize. I think we can get the list down to very few...
Well, I would suggest something more akin to “POPS on PSP/Vita - Config Research” or something. This thread is a lot less about SetRegion nowadays because of the better and truer methods of fixing games with configs.
Use pop-fe to convert your game for PSP/Vita. It includes automatic fixes.
Thank you for testing and verifying that.
@ronniesahlberg You can replace the Valkyrie Profile configs in the repository with the corrected ones that are attached.
The issue at least seems to be stemming from the added 0x0B command that fixes the audio crackling. The Vita config value may just need to be altered if PSP works fine…or both. Maybe I can do some tinkering with it this weekend.
Hi, yeah I was the one that started moving everything over to the wiki, but I never finished the migration. Maybe I will finish this weekend.
For any changes that you see need to be made, please make the edit and I will approve it. I will update that entry for Jackie Chan with this information!
