Translation patch crashing on PSP
« on: July 27, 2013, 10:22:51 am »
The Suikogaiden Vol. 2 translation for PSX is well along, but the patched file is crashing after title screen on PSP (6.60 PRO-B9).  We've had no issues with Vol. 1 or the unpatched file.

Anyone have experience debugging this kind of issue?  I know several patches have had similar bugs, but I thought we were mostly in the clear on the newest firmware.

If the patch works fine on real hardware, then it's just the PSP doing funny stuff (quite unusual if the original works), otherwise you're having a memory alignment issue somewhere or broken delay slots & lazy jumps. The way the PSP emulator interprets PSX code is quite similar to the real hardware, so if you have one of the CPU issues mentioned it's bound to appear on both machines.

(6.60 PRO-B9)

No idea if it makes any difference, but I'm pretty sure the cfw you're using is a little outdated. If I remember correctly, the latest stable version is PRO-C2, with PRO-Nightly being slightly more recent.

Yeah, dead on.  It was a just a regular old misaligned halfword load, and I was wrong, it wasn't working on PSX either.  Thanks for the tip.

The only thing that really matters is the version number, not all of those funky suffixes CFW authors like to add for who knows really what reason. "6.60" is the important part, the rest is irrelevant.

Glad the old tip always works. :beer:

I'm on CFW Exploit 5.03. But I wanna play games that are on 6.xx. Should I update on that PRO-B10 or PRO-C2? Sorry if I'm a n00b on PSP FWs.
