PS2 [Open PS2 Loader] Game Bug Reports

There might be a different story with Super Dragon Ball Z...
This game has been broken since OPL 1191 through HDD:
https://www.psx-place.com/threads/super-dragon-ball-z.22921/#post-162854.
Through SMB and USB it should be playable (without any modes) as far as I remember.

As for GTA Vice City through SMB what about mode 1 (or 1+3+6)?
However something is differently not right if mode 2 has started to block this game from loading
while everything was fine in older builds with it...

I seems to remember GTA Vice City doesn't require any MODE from other devices, so it could be a SMB only problem, but most probably there's some relation.

Try the game from USB if you want to check the compatibility (GTA games plays the same from any device being streamed by little chunks of data).

I've always just assumed that at least modes 3+6 were necessary because of reports of freezes during gameplay, but you're right, the game boots up just fine with no mode enabled at all. I just didn't test it myself with these two modes disabled for longer periods of gameplay, since I've never had an issue with those enabled in the first place.

As for mode 2 though, the game always had the studder issue for me when this was not enabled. I also think this is a game specific issue and not an SMB speed related one since games work fine for me with Mode 2 enabled or disabled corresponding to compatibility lists. I tested with SCPH-70001 (which tends to be slower over SMB because of the remaining MIPS R3000 processor as I learned here, but the latest OPL versions seem to work a lot better, so OPL might have already been optimized for this specific model) and an SCPH-77004.

For now, I just keep the working OPL build around and start this one up if I want to play the game smoothly with Mode 2 enabled. But of course, it's nice to aim for an all-in-one solution, where such an issue is resolved if possible :)

Sorry, I didn't post that I've already worked through the relevant, different mode combinations. I've tested with Mode 1 only and Mode 1+3+6 and the game boots up fine with these enabled, but the studder issue unfortunately always remains for me and only disappears with Mode 2 enabled in the old build.

As a matter of fact, the Mode 2 loading issue seems to affect the other two games of the trilogy as well. GTA III and San Andreas both hang on the title screen with it enabled but I didn't test it as deep as Vice City. So I can't say for sure if those two also stopped working with the build mentioned in my previous post or even earlier/later.

I wanted to share this with you guys since you have the insight and might figure out, what goes wrong here, so I try to be as specific as possible.
 
GTA SA has the stutter/micro-freezing problem from internal HDD (MODE 2 maybe relieves it a little, but I can't say it for sure since the heaviness of the problem varies at random. Very rarely it can even happen the game stops for a second or more).

The issue isn't present from USB (I don't remember from SMB) and I seems to remember there's a noticeable difference between PAL and NTSC versions. I remember 100% that PAL version is perfect from USB (never tried PAL version from HDD).
Device speed can easily affect compatibility in many different ways (some times is better more speed, other times less is better).

I never enabled any MODE on GTA 3 and GTA Vice City (either from USB and HDD). But it's been a long ago since last time I played them. I'll check with newer OPL builds.

Just curious, but did you try to see if GTA:SA still stutters while being played via HDD with Mode 1 (Accurate Reads) switched on or in lower DMA modes? I remember reading somebody around here float the idea that some games may exhibit performance issues if data gets streamed in faster than intended, but I don't think there was any actual evidence being posted at the time

I think I tested it in any possible way.

I remember I noticed some subtle differences in some cases, not even related to gameplay. For example, this screen:

241522-grand-theft-auto-san-andreas-playstation-2-screenshot-title.jpg


from HDD without MODEs, it freezes a little when appearing, then reach full brightness (it should fade in progressively).
It fade in perfectly smooth (if my memory serves me right) with MDMA 0 (you can notice similar behavior on many games).
Btw in game I didn't noticed appreciable differences (maybe it's still too fast?).

Maybe (just maybe), enabling MODE 2 or MODE 1 or lowering the DMA help avoiding the (rare) heavy freezing (one or 2 seconds long freezing), since the time it happened to me I was playing with default settings (no MODE, UDMA 4), it never happened that huge freeze i.e. when using MODE 2.

However it could be a coincidence, 'cause I played many other times without any mode but I got that kind of heavy freezing only one or (maybe) two times.

Anyway I think that HDD speed is useless on GTA SA. This game strictly respects some reading timing/speed apparently.
Indeed you can see the initial loading takes about the same time regardless of the device. So you don't lose anything lowering the DMA or setting MODE 1.

For example on GTA LC Stories the loading time is completely different depending on the device. It loads in a blink of an eye from HDD in UDMA 4.

Out of curiosity I set up a USB-Stick to check whether Vice City runs better and without micro studdering every few seconds. Just as you assumed the game runs smoothly with no compatibility mode enabled. It's even possible to run the game with Mode 2 off of USB, it doesn't freeze on the loading screen like it occurs with SMB (but it's not necessary at all since the game runs fine without any mode, in fact it's even counterproductive since this seems to make the loading a little bit slower ingame). GTA III and San Andreas also work fine with or without Mode 2 over USB, no freeze at the loading screen or hickups ingame. All tested with latest OPL Beta Build.

So, it seems this is really an issue with how OPL handles the games over SMB.

Thank you for the test.

About GTA SA the micro-freezing issue is always been present also from HDD.
GTA 3 and Vice City may have SMB specific issue. I'll check the games from HDD with the last OPL build this evening.

I forgot I haven't GTA 3 and Vice City installed on my current HDD (I was confusing with LC and VC stories).
However I tested GTA San Andreas:

I had it set with MODE 1+2. I leaved it so and tested with OPL v1.1.0-Beta-1629-453052c

Everything was fine, the micro-freezing is actually lighter than I remembered.
It stutters a little only when there's much happening on screen (and btw GTA SA Ps2 don't perform very well on the first place). When the screen is not too full, the movement is 100% smooth when moving the camera.

I noticed only one difference (comparing to rev. 1319 I was using) when performing IGR:
On beta 1.1.0 I got BSOD (so I had to hard-power-off the Ps2, since after IGR the Ps2 power button doesn't work).
On rev. 1319 the IGR works as it should (sending me back to OPL gamelist), so even if power button doesn't work I can soft-power-off from OPL.
 
Dog's Life SLUS 21018 it chokes my 39001 on the second introduction FMV, I've tried Accurate Reads and Disable IGR but nothing

SATA HDD

OPL v1
 
Fuun Super Combo (slps_257.81) does not work via HDD... works via USB, anyone knows if its working with some specific version of OPL
 
Could anyone test the "PADEMU-Fix" on incompatible games, or those with issues?

I wonder if it is limited to the BDM3-Build, or if it works on the official build as well.


Just activate PADEMU for a game which usually has issues and please report, when and if it changes anything anywhere.

official network adapter

can you try the game on your setup please

@Carloss, i tested the game Fu'un Super Combo with the internal HDD and works perfect using Mode 6,
this game don't like the IGR.

Next time try all the compatibility Modes and combinations of them before report a game.

Best regards.
 
i know that... i use modes 1 + 3 + 6 for all my games.. only a couple need mode 3 off, and recently i started testing mode 2, and i found out some differences in pop-in with Vice City

tried with the latest version, tried with .9.3, tried with some old betas.. no luck

i get BSOD right off the bat

i think it has something to do with the online support on this game, with other neo geo online titles i use the custom elf option to boot straight to the game selection menu, fuun super combo doesnt have the SELECT.ELF so i cant fast boot, instead there is a MOVIE.ELF that boots the all the logos until the intro movie, if you press start to skip the movie then it loops again to the logos

@Carloss, what a nonsense using modes 1+3+6 for all games.
Modes are only for the games which they need them, and it is needed to try them first one by one,
and not using combinations by default.

I repeat, for this game is needed only Mode 6, and pass the black screen.

This is not a problem about the online support and your way of loading the game using
the custom elf, another nonsense.

Game works perfect with OPL v1.0.0, i played both games of the recopilatory and they work flawlesly.

If not works for you, it is because you don't have the original adapter with an IDE HDD.
There are also clone IDE network adapters, chinese clone them like the SATA ones.

Or do you have some any other problem, but it is a problem from your side, it is not a problem
from the game and not from the OPL.

Best regards.
 
is it wrong to try to run OPL in a "cleaner" way?

the custom ELF is nice to use with compatible game for faster boot... is it wrong to do that?

there is probably something wrong with my setup if the game does not work via HDD, im using official network adapter.... wherever

te deberias de cambiar tu nik a "ELMANIAS".. haha, estas medio malito
