Ok, I have some to add - I just tested my entire PSX game collection.
I found that psx4pandora was very crash-happy at 850MHz (which is the highest stable speed my Pandora can handle, as far as I'm aware), so these were all tested at 700MHz.
Title: Bust-A-Groove
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Playable
CPU Speed: 700MHz
Comments: The game's FMVs run too fast. However, the game itself, and the music, is a bit too slow.
Title: Crash Bandicoot
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz
Comments: The speed of the game and the music seems to fluctuate quite a lot. The ground looks strange in places.
Title: Crash Bandicoot 3
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz
Comments: The speed of the game and the music seems to fluctuate quite a lot. There are some rendering errors on some of the 3D models - some polygons that would appear behind others on real hardware, are appearing in front here, and vice-versa. There are also some minor glitches in some of the special effects.
Title: Croc: Legend of the Gobbos
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz
Comments: The publisher and developer logo FMVs are too fast, and the in-game speed seems to fluctuate wildly (it sometimes runs too fast). Cutscenes are not played. There are some strange lines along the edges of some polygons, which should not be present.
Title: Croc 2
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: The publisher and developer logo FMVs are too fast. The game's boot-up introductory sequence begins but is then skipped automatically, so it is never played. There are some strange lines along the edges of some polygons, which should not be present. When the game's intro begins after choosing to start playing, the game's cinema-style widescreen bars drop in as normal, but then move back upwards again, leaving the display showing the place where the intro should start, but with nothing else happening. After this, nothing else ever happens. I hope you enjoy looking at that empty beach chair and umbrella!
Title: Heart of Darkness
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: The FMVs are too fast. The game seems to begin as normal, but after the introductory sequence, the game drops back to the title screen - if you press start again now, it will show an FMV from a bit later in the game, and then drop back to the title screen again. Pressing start again now will cause it to display an old screenshot with the caption "HEART OF DARKNESS DEMO" at the bottom, and after this the controls cease to respond.
Title: Klonoa - Door To Phantomile
Region: PAL
Format: bin
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz
Comments: The FMVs are too fast, and in-game the speed seems to fluctuate (though it is generally slightly on the sluggish side). The music seems to speed up and slow down, too. Some sprites/2D elements have alternating lines that appear to be shifted to the left or right, making them look as if they're underwater.
Title: Klonoa Beach Volleyball
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Playable
CPU Speed: 700MHz
Comments: The game and its music run a bit more slowly than they should.
Title: Lomax
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well

Comments: There is currently no background music due to this game using redbook audio, and the game runs slightly too fast.
Title: Mega Man Battle & Chase
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz
Comments: The speed of the game and of the music seems to fluctuate quite a lot.

Title: MegaMan Legends
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well

Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)

Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well

Region: NTSC-U
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well

Title: Tail Concerto
Region: NTSC-J
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: The game's FMVs run too fast. Some sprites/2D elements have alternating lines that appear to be shifted to the left or right, making them look as if they're underwater. Whilst you can press start to skip the opening FMV, the game controls do not respond when you reach the title screen.
Title: The Adventure of Little Ralph
Region: NTSC-J
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Works well
CPU Speed: 700MHz

Title: The Misadventures of Tron Bonne
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: The boot-up FMVs are too fast, and get a bit mangled and corrupted. The ground looks strange in places. The game and its music fluctuate in speed a bit. The game will get stuck in a loop as soon as the first line of dialogue is spoken - this can be broken out of by pressing start, and then pressing start repeatedly until the status information in the top left-hand corner of the screen scrolls in. The same must be done every time the game attempts to go into dialogue, or else control will not be handed back to the player. Pausing the game causes it to drop to a black screen and never recover. Reaching the spot where a cutscene ensues prior to the first boss causes the game to drop to a black screen and never recover.
Title: Tombi!
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: The game's FMVs are too fast. Some sprites/2D elements have alternating lines that appear to be shifted to the left or right, making them look as if they're underwater. When in-game, the speed of the game and the music are too slow, the text is unreadable because it appears as corrupted red blocks, and when the first conversation in the game is over, the display does not get updated, even though the game can be heard as working in the background.
Title: Wild ARMs
Region: PAL
Format: bin/toc
Emulator Version: First Beta (Fixed version from Pandora app-store)
Status: Not working
CPU Speed: 700MHz
Comments: Trying to start this game instantly crashes the emulator.
EDIT: Whoops! I just realised that I forgot to test Mega Man 8 (PAL). I expect it will be the same as Rockman 8 - Metal Heroes, but I will test it tomorrow, to be certain of this.
