Edit: @smegforbrain: What I'm starting to wonder is if switching the BIOS region to PAL is bypassing a specific type of copy-protection. Hmm. Well, I finally got around to testing Tomba! 2 a bit last night. I'll try and get around to fiddling with it some more this evening with your bypass method to see what happens. I'm pretty sure that somewhere on the internet, there is a decent list of the copy-protections being used in PS1 games and their regions. Yeah, I've got one list I try and work from. But I'd like a little bit more details, since this is one list, and there seems there may be several types of protections out there. |

Sorry this can't be the comprehensive post you wanted, smegforbrain, but at the very least, I recall there being several different versions of LibCrypt (1-3?), which was one of the more used protections in PAL games.

Yeah. Just going over the list there has been some success in getting PAL copyright protected games to run in 1.7 and 1.8, but without knowing a lot about copyright protection, I can't really make heads or tails of it.
I'll try and do some more research on it, see if there's anything I can find that might shed some more light on this.

Tomba! 2 with PAL bios worked wonderfully. I've made a note of this on my list.
BoF4 I wanted to check, but I forgot that what I have is a patched copy of that one. Blah.
Legend of Dragoon with PAL in v1.8, as Gamesoul already reported, also works wonderfully. The fact that this game still needs some sort of bypass, even with subcode reading, obviously ties pinto why we need more info on what types of copyright protection are out there. Still, the game works now. At some point I'd like to go back and test with older versions, just to make sure.
Wild Arms 2
It turns out I had this game after all.
Tested in v1.7 and 1.8, no need for any command line options that were from what I've played so far - through the opening area of rescuing the hostage with the New Recruit character.
But during the fight with the big creature after the hostage stuff, the thing went to use Laser Breath, and the camera panned around, and then nothing else happened. Music still played, character movements just looed. I'd used the Shot Weapon right before that.
This one also works with using a PAL bios in v1.6. And after trying to kill that boss again, no problems getting through it.

I'd like to add here the point in Final Fantasy IX (US) where it freezes after an ATE event in the monster-free area of the Evil Forest (toward the beginning of the game)... using a PAL BIOS gets around that freeze too, and might very well get around a couple other random freezes that people have reported with the game. The freeze apparently doesn't occur in v1.6 and earlier, so I tested v1.7 and v1.8 using the original game disc (I was too lazy to extract it as I usually would).

Might it be an idea to get this thread stickied, GM? I keep finding myself referring people to it, and just before making this post, it was sitting at the bottom of page 7 of the Help & Support section.

First post has been updated with a few more tests. I also agree that this thread could use a sticky, as it's slowly growing into something interesting...

I hope noone minds a 'newbie' question, so if I want to run Metal Slug X in Psxfin, I should search google for a patch for it, and if I do, run command line to get it running?
So 'other' emulators like EpsxE do not emulate the protection of a Playstation? Because I'm pretty sure I got it running in another emulator, and I am in no means critisizing any emulator, I am just curious from a technical standpoint what is going on when the emulators try running the game...
And yes, I know it is in MAME, but I like having legal ports of games and have been interested in playing the legal Playstation ports on my PC, as I spend more time playing games on my PC than my girlfriend's Playstation or my Playstation 2...

No, paratech, pSX and other emulators try to emulate the ability of a Playstation to play protected games; however, since the ways a Playstation achieves this have never been properly documented, different emulator coders have taken different approaches. Just as some games will run in other emulators that won't run in pSX, so pSx can run several games that other emulators can't. The difference is that pSX is still under active development (some other Playstation emulators _are_ still in development, but none very actively) and still has the prospect of succeeding in running many more games.
As far as Metal Slug is concerned, it doesn't appear to be copy protected, so a) looking for a patch won't help and b) the reasons why it won't run aren't around copy protection. If you want to get it running, first read Things to Remember when Posting Reports prominently displayed at the top of this and every other page in the forum - which you should have read anyway before posting, but clearly haven't. Search the forum for your game to see if anyone else has posted on it, and then consider whether to bump their thread (if it's about your game and contains information that's useful and can be added to) or to start a new thread in the appropriate forum. In this case that would be Game Compatibility - and give the required information, plus as much information as possible about how you're running - or trying to run - it.

Seems to have been stickied! And Wild Arms 2, which wasn't playable without a patch (or PAL BIOS) until pSX Author incorporated subcode reading into v1.7 or 1.8 and then became eminently playable, has stopped playing again as of, I think, v1.10. A new member called rebirth has confirmed this. I'm fairly sure I posted something to this effect at the time, but can't find the post... Anyway, it now goes to a copy protection screen instead of just stopping. However, PAL BIOS to the rescue! Still plays fine with scph-5552.  Edit: just to clarify, going to a copy (or mod) protection screen is what I meant by "has stopped playing again as of, I think, v1.10." |

I thought Metal Slug X was on the list, I wasn't trying to ask how to get it running as much as trying to understand if it was protected, what was going on, I thought it was protected. I'm sorry it went off topic... No, paratech, pSX and other emulators try to emulate the ability of a Playstation to play protected games; however, since the ways a Playstation achieves this have never been properly documented, different emulator coders have taken different approaches.

As I said, if you'd read Things to Remember when Posting Reports, you'd have seen the links to two Playstation copy protection lists. Any game that's known to be copy (or mod) protected should appear there. But the real reason I pointed you to Things to Remember when Posting Reports was so that you'd know where and how to make a report on your game - which you should, since unless it's also known as 'Metal Slug: Super Vehicle 001,' it hasn't been reported before. Even if it is the same game, no report's been made since v1.6 of the emulator.

WILD ARMS 2 PROTECTIONI'll try to check v 1.9 and 1.10 at some point to establish when it happened. Edit: as I said, though, it works fine with a PAL BIOS. Edit: Ok, pSX 1.8 was the last version that ran Wild Arms 2 with an NTSC (scph1001) BIOS; versions 1.9 and 1.10, like v 1.11, go to the copy/mod protection screen. I tried with a .ccd/.img/.sub image and with the Playstation CD - same results for either in each version. All versions run the game fine, image or CD, with a PAL (scph5552) BIOS. FWIW, playing from a CD gives the same output in the DOS window in all cases: and then the 1: 00000000-0003585a line repeats until it's crowded everything else out of the window. No output in the DOS window using an image, in all cases. Most of this was done only with disc 1; trying the disc 2 image in v1.10 and 1.9 gives the same results; I didn't try the second disc in other versions or with the second CD at all. Ultima: That's three double-posts I've corrected for you in the last day so far

The Legend Of Dragoon can run with scph7502.bin (E) BIOS. I have no sounds and talking issue. But then again there might be some problems other wise. pSX 1.11
