Time Crisis 2/3 Timing issues with some BIOS revisions

[ghost]

PCSX2 version: 1.5dev 2400

PCSX2 options: All default, speedhacks off

Plugins used: All defaults

Description of the issue: The games "Time Crisis 2" and "Time Crisis 3" fails to load on some BIOS revisions (Tested on 2 differents PS2 slim BIOS)

• PAL 2.0 (rev 14/06/2004) load them fine
• USA 2.2 (rev 10/02/2006) fails to load them with the following error: sce1394SbEui64(): failed -1

Note: set the EE cyclerate to -3 allow the games to work on the 2.2 BIOS.

How to reproduce the issue: Load Time Crisis 2 or 3 on a 2.2 BIOS (or other than 2.0).

Not a regression

PC specifications: AMD fx8350 GTX 1060 Windows 10 64bits

Looks like this is caused by a lack of BIOS .nvm section as mentioned here: https://forums.pcsx2.net/archive/index.php/thread-38332.html

sce1394SbEui64 seems to be an IOP function related to I/O likely used during Guncon enumeration.

Humm, maybe it's not related because when I boot the game with EE cyclerate -3, this error still appear but is not fatal.

And by the way I extracted booth BIOS with the same dumper so the .nvm should be fine.

Can you retest this with latest master by any chance? There were changes to timers since then, maybe it is fixed now.

This is a firewire issue, not a timing issue
