PS1/2 OPL stuttering

[OldGnashburg]

I just recently installed a 500GB HDD (it was a PS3 HDD) with SATA MOD, I transferred Final Fantasy XII onto my Hard Drive using WinHiip after formatting with HDDManager and Launching OPL once, but I still have small but noticeable stuttering. Do I need a faster HDD (I am using an official PS3 HDD probably 7 years old), or did I install it wrong (different configs)? Can anybody point me to recent guides, I want to have the setup with the best performance/compatibility.

Sometimes you have to activate certain modes to get games to work better, use this compatibility list

Final Fantasy XII SLES_543.54
SLUS_209.63 DVD5 892_DB HDD / SMB 6 YES HDD=50 YES SMB: the only Issue is on FMVs, they freeze sometimes, but you can jump them. 12/31/2016

The problem is it's talking about using SMB which is through ethernet for this, but you could try it with HDD, activate mode 6. Also it's not 100% perfect on some games they never perfected the compatibility, although it's pretty good overall. Unless there's something wrong with the hard drive or it's from china it's probably fine if it's working at all.

Thank you so much! New to PS2 Modding, I'm on a quest to hack 'em all, I only have 2 consoles remaining. Nice to have help, especially considering how old the console is.

First try turning on Mode 1. If this does not fix the issue, turn Mode 1 off, and set the DMA mode to UDMA0, or even slower. If neither of those options work, then turn on both Mode 1 and use the slowest DMA mode (MDMA0 I think?).

The issues with more modern HDDs (and later versions of OPL) is that data is being sent "too fast" and you need to slow it down.

How do I turn on and off Modes?

Highlight the game in OPL. The look near the bottom of the screen to see which button to press to modify the game’s settings (may be theme specific).

If anyone's interested, I'm conducting my own tests which games are most compatible on a USB thumb drive via OPL, you can find a list of games that are running with no FMV stuttering without changing a game configuration on my blog along with a few configuration guides, although I haven't updated it for a few months now, but will add more games on the list on a later date.

Tested In: 0.85 version OPL (Haven't Updated to the 1.00 Version Yet), and PS2 Fat Models SCPH 10000 and SCPH 35000 and a Sandisk USB Thumb Drive.
