PSX4droid V2 1.0.9 (most recent)
I will mention any tweaks used. I am a Nexus 1 on 2.2. Cycle multiplier seems to help on some games which work but feel a tad slow.
I bolded the games I personally have issues with
Let is be said if you use save states from old different versions of this app they are more prone to fail. Load from a memory card when trying new things.
Alone in the Dark-One Eyed Jack's Revenge: Works at full speed in V2 1.0.9
Alone in the Dark the New Nightmare: Runs good in V2 1.0.9
Alundra: Works just fine...should be a SNES game IMO
Arc the Lad 1-3: All 3 work for me
Azure Dreams: Works just fine
Baulder's Gate: Seems to run fine...this game is hard on the eyes on a tiny screen though
Beyond the Beyond: Works
Brave Fencer Musashi: V2 1.0.9 works. Older versions of V2 were giving me a terrible sound buzzing issue
Breath of Fire 3: Runs fine for me
Breath of Fire 4: V2 1.0.9 has no issues starting the game, no crashes in menus, and no invisible walls
Bushido Blade 1 and 2: V2 has definitely upped the speed on these. They are the only 3D fighting games i can find that run almost 100%
Castlevania SOFTN: V2 1.0.9 seems to run this fine. Increasing the cycle multiplier helped me on speed. A lot of people are picky on this one but in my opinion it is fast enough to play
Civilization 2: works fine
Command and Conquer: I have not encountered any issues
Dino Crisis 1 and 2: V2 1.0.9 the games run pretty good now. Dino Crisis 1 has stuttering sound but I can still understand them. I find that using DIV Root Counter and increasing the Cycle multiplier helps with the sound
Dragon Valor: No issues for me
Dragon Warrior 7: This game still will not work. the text will not show after I put my name in. Tried all combinations of tweaks and cycle speeds
Driver 1 and 2: No issues
Dune 2000: No Issues
Ehrgeiz: Still too slow to enjoy.
Einhander: works just fine
Eternal Eyes: runs good
Fear Effect 1: V2 1.0.9 is the best this game has ever run
Fear Effect 2: V2 1.0.9 is the best this game has ever run
Final Fantasy 7: Runs well enough for me and I verified that it no longer has submarine glitches
Final Fantasy 8: v2 1.0.9 works perfect the Garden will move and videos play. It may not be 100% but it is worth playing on your phone, even if you just want to play cards!
Final Fantasy 9: v2 1.0.9 I have confirmed that the Dali Airship crash is no longer present and that the crash points in disc 3 and disc 4 are safe as well. I assume that the others I had found previously are fixed as well
Final Fantasy Tactics: Works fine for me
Front Mission 3: Well I heard from Zodttd that this works on his Galaxy S phone. For me on my Nexus one everything works fine until I begin to fight with the first robot you encounter in training. At this point the game freezes. I have tried all tweaks and even tried turning the skip battle feature on in game options
Grandia: No problems
Gran Turismo: It is fun as is but could be a little faster
Gran Turismo 2: It is fun as is but could be a little faster
Hoshigami-Ruining the Blue Earth: Works and no one has heard of this game so why do I even bother
Hot Shots Golf: V2 works well. I sped up the cycle multiplier on this one a tad for best performance
Jade Cocoon: No issues for me
Legend of Dragoon: Seems fine to me
Legend of Legaia: Happy to say you can play 100% through this game a beat it without any skipping. There is a slow down in battles though when you perform special attacks but it is bearable
Lunar 1: Works fine
Lunar 2: works fine
Mech Warrior 2 31st Century Combat: Works good
Medal of Honor 1: No issues
Medal of Honor 2: no issues
Metal Gear Solid : I use the Integral version which runs about 90% speed and has near perfect audio
Metal Slug X: Still crashes when selecting a character.
Myst: Works well in v2 1.0.9
Parasite Eve 1: I have not had issues but keep in mind I have only done the first few battles in the game enough to test the mechanics as well as to make sure the videos done freeze
Parasite Eve 2: v2 1.0.9 Seems to run fine with Div counter tweak on
Rayman: CDDA not supported
Rayman 2: Runs good for me.
Resident Evil 1: Runs good for me
Resident Evil 2: Runs good for me
Resident Evil 3: Runs good for me
Riven: Runs good for me
Silent Hill: Runs good for me
Soviet Strike: Runs good for me
Star Ocean 2: Runs good for me. no longer has sound issues

Suikoden 2: Runs good for me
Tales of Destiny: Runs good for me
Tales of Destiny 2: Runs good for me
Tekken 3: Too slow to enjoy

Thousand Arms: This game is ALMOST playable. Basically the audio loads now but there are still graphical errors with the ground and text does not load in the text boxes.
Tomb Raider: CDDA not supported
Tomb Raider 2: CDDA not supported
Tomb Raider 3:Runs good for me
Tomb Raider 4-5:Runs good for me
Twisted Metal 2: Again Zodttd says this should run without issue but for me on my N1 it crashes at the main menu. I have tried all tweaks. This happened after the first release of V2 for me and has persisted. Anyone else have this issue? 1.7 still runs it fine for me so not a big deal
Twisted Metal 4: Runs good for me
Vagrant Story: Runs good for me
Valkryie Profile: Runs good for me. Game takes awhile to test but the intro no longer freezes

Wild Arms: Runs good for me
Wild Arms 2: Runs good for me
Wing Commander 3: Runs good for me
Wing Commander 4:Runs good for me
X-Com UFO Defense: Runs good for me
Xenogears: Runs good for me. Note if you try and load or access your memory card from the games main menu it will not work. It does work fine once you are actually in the game though. I just keep a save state right after the intro. This game is also a good way to copy/delete other games saves off your memory card.
