I just finish to test some stuff with DSTWO Linux Beta1.0 here is my feedback, dunno if it will be helpful 'cause it's seems to be an old thread here, but maybe it could be helpful for not waste time.
For this test, I used a DS Lite + an EZ Flash 3in1 (not sure if it's helpful or not I don't think so but in the doubt^^) + a DSTWO+ with a 32Go kingston sd class 10
For this first part, all the apps needs to be placed in the first GAME folder : sd root:\GAME
NATIVE EMULATORS
FBA320 V1.0
It works pretty good, a little bit slow sometimes but very playable, big games needs cache files (like cps2 or neogeo games) you can find the converter here :
http://dl.openhandhelds.org/cgi-bin/dingoo.cgi?0,0,0,0,115,150
Some games needs to be run by cache file (.fba) and other by zip file.
I'v tried different settings here is the one that seems the best I've found :
Dingoo Mhz : 396 Mhz
Video aspect : scale fast / scale normal for vertical games (for vertical games it seems you can change to scale fast after a first launch in scale normal)
Sound : On 24000hz

MAME4ALL V1.0
Slow but interesting for some games that have some freezing problems on MAME4ALL DSTWO

No freezing problems anymore with these games.
PSX4ALL
Well, what to say... impressive but slow & no sound, anyway it's a cool port!
I'v tried different settings here is the one that seems the best I've found :
Show FPS : OFF
Set NULL GPU : ON
Cycle Multiplier : 4
Games tested :
Blood Omen, FFVII, Crash Bandicoot, Disney's Hercules, Einhänder, Vagrant Story (save data corruption happens sometimes with this game, nothing to do, just overwrite the corrupted savegame and cross your fingers^^)
Dingux PicoDrive V 1.35 (openDingux optimized version)
Very playable when you find the correct settings but the music doesn't work
I'v tried different settings here is the one that seems the best I've found :
Renderer : 8bit fast (except for some games like hota for example but just press X in game to switch to the 8bit accurate renderer setting)
Frameskip : 1
Sound Quality : 22050hz stereo
A320 CPU Clocks : 396 Mhz
Games tested :
Cyborg, Demolition Man, Earthworm Jim, Flashback, Flink, Heart Of The Alien, NBA JAM, Pitfall, Popful Mail, Sonic, Spiderman, Terminator.
Note: with some games only the first stage seems to be playable even after convert .bin file to .iso file, .mp3 files and edited .cue file.
OpenBOR
It works fine, I've tested more than 50 games, actually it depends of the games and their size, the biggest game I've tested is about 163Mo, up to 163mo all the bigger paks I've tested doesn't seems to work but maybe I didn't find the good version of the games.
Midpath (java emulator)
Works fine with little game but little bit slow with bigger game otherwise the maximum file size that the emulator can launch seems to be 1mo. The config file menu need to be edited with notepad to run the emulator in english, you can find a great tutorial here :
https://boards.dingoonity.org/dingux-releases/midpath-4-dingoo-v0-1/
uNGP (Neo Geo Pocket)
Little bit slow but very playable & very compatible with the ngp games catalog.
I'v tried different settings here is the one that seems the best I've found :
Video Options
Frameskip : 4
Renderer mode : normal
show fps : off
Sync 60 fps : on
Sound Options
Emulator sound : on
Stereo sound : on
SampleRate : 22KHz
WSC (WonderSwan Color)
Slow without sound, setting menu and with a poor compatibility, WSC is not the best emulator but you can play few games, I've tried 15 games, it's playable and actually it's seems to be the only way to play wsc on ds lite.
DCASTAWAY (Atari St)
Great emulator with a cool interface menu (but menu freezes sometimes), works fine.
UAE4ALL (Amiga)
Good emulator with a cool interface menu, works fine.
NON NATIVE EMULATORS, TRANSCRIPTORS & GAMES
For this second part, all the apps needs to be placed in the second GAME folder : sd root:\GAME\GAME
EMULATORS
SDL-Vice & FrodoDingoo (Commodore 64)
It works fine but both are needed 'cause some games works on Frodo and doesn't work on SDL-Vice and vice versa, on SDL-Vice the "m" key & the "n" key are inverted on the virtual keyboard
Dingux int v1.0.0 (Intellvision)
It works fine but it's not enought to run all the full Intellvision romset, otherwise, the compatibility is still good you can play with a lot of games, if you install it, it's better to remove all homebrew roms that comes inside the archive, most them doesn't work.
Dingux-Vectrex
It works fine, a good emulator.
neo4ALL (Neo Geo cd & MVS)
A good emulator to play exclusive neo cd games (except kof96 doesn't work) and games that doesn't work on neoDS, but that's all, 'cause music doesn't work, only sounds. Like DCASTAWAY menu freezes sometimes actually you have less than 1mn to choose your game and settings, to get a little delay before menu freezes, run a game and go back to the menu by pressing R key, now you have time to do your settings.
I'v tried different settings here is the one that seems the best I've found :
Frameskip : 1
CPU Settings
68K CLK : over
Z80 CLK : over
Games tested :
Ironclad, Crossed Swords II, Futsal - 5on5 Mini Soccer, Last Hope, Neo DriftOut
TRANSCRIPTORS
cgenius (Commander Keen)
CZDOOM*
Duke3D
hheretic
HHexen
hota (Heart Of The Alien / Another World 2)
lotr (lord of the rings vol.1)
OpenJazz (Jazz Jackrabbit)
OpenTitus (Titus the Fox)
RAW320 (Another World)
rott (Rise Of The Triad)
*Note : CZDOOM can crash and corrupt files sometimes, especially when you launch PWADs, it's better to make a copy of the prboom, prboom.cfg, prboom.wad and prboom-game-server files somewhere else on your sd card then when CZDoom crash, you can remove the corrupted files and copy/paste the good ones by using DSOrganize, don't forget to remove prboom.log.txt & tranmap.dat files too when it's happen, don't worry, these files will be automatically regenerated by the prboom engine.
Note 2 : Before to apply the method above check your prboom.log.txt with DSOrganize, normally if you had a czdoom crash just before, the size of your prboom.log.txt should be 0.0mo, to fix the problem, open the file with DSorganize by pressing A to read the .txt file, then close the file, normally now after reading, your prboom.log.txt regained its original size and then you can launch again CZDOOM.

ISSUES
* sd card corruption (never happens to me for the moment)
* there is a sound problem with most of the apps, after few minutes the sound stops and you can't quit the app except by pressing R+Start
* sometimes dmenu.ini files can crash dingux, like CZDOOM, it's better to keep a copy somewhere else on your sd of the dmenu.ini file located in sd root:\LOCAL\dmenu and the dmenu.ini file located in sd root:\LOCAL\dmenu\backup, use DSOrganize to remove/copy/paste the files and fix the bug.
