It seems I can't add a row in the spreadsheet? I wanted to add Agent armstrong.

Gotta wait till Hurricane sees this, so he can edit it. He's locked out the game list from editing, which is actually good thing, as someone could wipe it out otherwise in worst case scenario.

@dd-indeed @BobHarris I've added Agent Armstrong. If you see any other games missing just @ my name and I'll add them.

Man it's been demanding job to test the games haha, gotta ease off and play more. So far I've learned these things about the PS1 emulation:

Talking about the Double Resolution-option, it causes multiple different kind of issues with games. Mainly it's just very demanding for the whole system and games have some slowdown, audio cuts and jerking, but sometimes the games works really nicely with it and only have some minor graphical glitches, which usually happen with loading screens. I'm not an expert in terms of understanding the development of these things, but I really hope, that some game specific fixes would be introduced at some point or further develope and optimize this feature, as it really makes the PS1 games shine. Some games can be even concidered to look like their PC-port versions, when that feature is enabled.
The previous overclocking I had actually had significant impact to the overall performance. As soon as I slightly dropped them down, many games started to have some lag with DR-option Enabled. So to me, RPi 3 is capable of running PS1 games in full speed without any hiccups, if you are using proper cooling system for the RPi due the heavy overclock you have to do. I will improve the cooling of my current system and return back to the original, rather heavy overclock. I had to drop it a bit, as I realized that the whole system runs a bit too hot.
About some audio related issues with certain games, I dunno that is it about the audio driver or something else, but sometimes I hear these weird, low quality sounding sounds on the games. They remind me of 8 or 16-bit era sounds in some terms. One example of this can be heard in Crash Bandicoot 3 Warped, on the 4th level, Bone Yard. Walk up to the point, where you do this sort of U-turn and briefly you are in a sidescrolling angle. There is these lava-rivers behind you and their sound effect has this weird low quality crackling-sound. It could be like that by the game's design or something, but I would really wanna know, that do others hear that as well.
As for the DR-settings, I noticed, that you need to select the suitable speedhack option for each game, as the speedhack does some weird things sometimes, when it's on or off. Many games tend to have some sort of scaling conflict, especially in pause menus, that causes the backround to go haywire. Demolition Racer's pause menu is a good example of this, when the speedhack is off, there is slight vibration in certain places on the picture, but when putting the speedhack on, the whole screen goes absolutely nuts and is pretty good for getting motion sickness. :P
For video driver, I went for SDL Dispmanx over the stock GL. That is one key thing to make the DR-feature work better. Also, some games with stock emulation settings do work better with that as well, so you might wanna try it out, if you see some graphical issues with games.

no overclock is required to play psx games at full speed on a pi3. a pi2, even. your configuration is not right.

@dd-indeed The "double resolution" thing got me thinking of something else I've discovered that some people may already know but some may not. Using the "Enhanced Resolution (slow)" and the "Enhanced Resolution Speed Hack" functions to increase resolution on lr-pcsx-rearmed seems to make translucent-ish objects become completely invisible. In most cases like MGS using the Stealth Camouflage it doesn't make much of a difference, But in games such as Tomb Raider 1 where the save spots are translucent crystals, it makes it impossible to save in-game. Just something worth noting to those that don't know.

Are you really standing behind your words, that you don't need to overclock RPi 3 in order to run PS1 games in double resolution mode with stable full speed ? I seriosly doubt it.

I noticed this issue in Dino Crisis 2, the characters are transparent on cutscenes, if you use DR with Speedhack On. Disabling Speedhack makes them be somewhat blurry.

whoops, didn't see you mentioned enhanced resolution before (stop calling it DR!), but even then. you should ALWAYS have the speedhack option enabled when using the ER mode to get proper performance. the pi3 is fine with ER + ER SH. you can sometimes get away without the speedhack, but not often.

the enhanced resolution + speedhack has too many visual bugs for me to consider it more than a curio. things like doom are a mess with it on. i'd prefer a shader. you certainly shouldn't be using it when contributing to compatibility spreadsheets, but there you go.

@dankcushions

I still have a feeling, that you didn't read my message properly or didn't understand what I meant.

And shaders are only good for 8- and 16-bit consoles, since they give awful results on 3D-games of 32-bit consoles.

BobHarris

@dd-indeed How's that? The crt shader makes my ps1 games look exactly like I remember them (both 2d and 3d games). I wouldn't want to play them without it.

DD-Indeed

@bobharris

Yeah, well, some people like to play them as they were, I myself get a headache, if I would need to go back to that original look again due being used to modern TV's and image quality.

But anyway, had enough of this offtopic.

Tekken 3 will get slowdowns on an oc'd 1Ghz pi2 without any shaders or Enhanced Resolution. It's the only ps1 game I tried that ran too slow, but I would need to find a list of those higher native res games to verify it is that. I also haven't tested it in over 6months so I would need to re-test for any emulation speedups/fixes (if any) with it.

Found a rough list if anyone wants to test on an oc'd pi2 (or I can if I can remember): http://shmups.system11.org/viewtopic.php?f=6&t=54382

If a game runs too fast, should I list the game as 'has issues' or is there an easy fix for this somewhere in the settings?
Command & conquer runs 10-20% fast.

@bobharris I would consider it a bug

Final Fantasy 8 runs smoothly until I enter a battle - then it completely freezes, and I can't recover the game. Anyone have tips for this issue?

I'm running:
Rpi3B
RetroPie 4.2
5V/2.5A power supply
lr-pcsx-rearmed
SCPH-1001 (standard)

I've tried pcsx-rearmed with the same issue for FF8. FF7/FF9 don't have that issue whatsoever.

@brickle select + retropad X > options > InuYasha Sengoku Battle Fix > enable

brickle

@dankcushions That didn't work for me :(. Still freezes upon battle entry, and causes display and audio stuttering as well. Any other guesses?

Medievil = Unable to select between New Game and Load Game on the startup screen and the icons of those are broken.

+1 to that one. Initially, I thought that the cause was a corrupted rom, but after trying 3 different roms (PAL and NTSC), I consider it as an emulation glitch. Gameplay is not affected, so far, at least.

DD-Indeed

@tasosdio

And you used Enhanced Resolution when you tested it ?

BobHarris

@aengeon Is there a specific point in the game where this happens? (Tomb raider 2 freezes) I would like to try to replicate it. It has not happened to me so far.
