DraStic (Nintendo DS emulator) OUT NOW for pi2/3!

jcarhat

All of those bases are covered, except im not too sure about the first one. I havent changed any settings related to the SD card so I think I'm safe.

It'sjust odd because the games work. I shot down the system, back up my image, current image still works fine, but when I re image the pi certain psx games dont work. so the issue I htink has to be with the way im backing up my image, but cant narrow down the problem because the process is so simple.

@jcarhat
I guess it could be the software you're using to backup your SD card or it could be the card reader you're using on your PC/Mac.

I'm use Windows for this and I've heard that it's best to first format the SD card before flashing an image on it. I use SD Card Formatter 4.0 and then after formatting I use Win32 Disk Imager to flash the image to the SD card.

Also if you have another SD card reader, maybe try that one and see if you have the same issues.

It's usually a little trial and error before we discover the culprit ;-)

Most games Ive tested seem to run very well! Using a ps3 controller- mapped the stylus to the Lstick and am using the R2 button for clicking. Works great! Shame Zelda Phantom Hourglass instantly crashes :/

Has anyone found a way to configure/bypass MIC-requirements in game? Games just end/return to emustation when it is waiting for MIC input.

Please scream out loud when Drastic is moved to main packages, and please add to the compability list if touch input, mic or accelerometer :) is required to play the game.

Thank you for your awesome work! Looking forward to Retropie 4.2 :)

do you know if backgrounds are working with this version? (2.5.0.3)

I know Drastic run background as kind of overlay but I can´t find the "background folder" in rpi or some variable in drastic.cfg.

Anyone know if there's a solution or fix yet to run command issue mentioned earlier in the thread?
The one where after running drastic once, run command no longer functions (can still run more ds games but black screen for anything else) and one basically has to fully restart the system to get it back?

I did a little testing and have noticed that the runcommand is still fully functional, just covered by the exiting image of DraStic. As a temporary workaround, could this be cleared using a command executed from the runcommand-onend.sh script? I don't know the bare bones operations of RetroPie, but I made a Kodi addon not too long ago for OSMC that would launch the Lynx web browser and in the script I had to clear a certain virtual terminal for Lynx to show itself. Would adding a similar command to runcommand-onend.sh work here until an update is released?

This could work but I didn't find the name or PID for the process causing the "black screen" issue. I tried sudo killall drastic but that didn't work and it wasn't running anyways.

@backstander

When I made the Lynx addon for OSMC, I had to use the following line to clear the virtual terminal at different points:

sudo openvt -c 7 -s -f clear

I don't know if it would apply here as well, but I believe you have to know the virtual terminal number, which was obviously seven in the example above.

The emulator needs fixing to restore the framebuffer correctly. Bugs should be reported to the developer.

Arcuza

You pros who know things, do you think we will ever see a lr-drastic?

BuZz

@Arcuza not unless the author creates a libretro port of it - it's closed source. Also being closed source he would have to build the libretro core for each platform etc. I would say it's unlikely.

@lilbud I had this happen, but found out if i click on the opposite screen where i wanted to click on the actual screen that should be clicked...it worked. i think only the bottom screen works for touch.

I'm really digging this emulator a lot. I've been messing about with games that don't require a stylus, those of us that don't have a mouse or want to map the analog stick. Yeah, i know, the point of the DS was the touch screen but for emulation purposes here is a small list of games running great and require no styles at all to play -

Contra 4
De Blob 2
Kirby: Super Star Ultra
Mario Kart DS
Mr. Driller: Drill Spirits
New Super Mario Bros.
Sonic & Sega All-Stars Racing
Tetris DS
Super Mario 64 DS (Does require stylus initially to start the game)

Is there a dev blog for drastic?

Hi,

I've gotten the emulator to work by editing the config but does anyone have the problem that whenever you want to see the menu that all you see is a black display ? I can play games fine but whenever i try to go to the ingame menu my screen goes black.

Not sure if it matters but the screen i use in my picade has a maximum resolution of 800x600 if i remember correctly, i'm just not sure if resolution is changed when going to the emulator's build in menu.

If somone had the same problem what did you do to work around it ? thanks

I downloaded Drastic from RetropieSetup (after updating the script, the core packages, everything), put my roms in the right folder, but I just can't see it anywhere. it doesn't show up in ES (even if I modify the es_systems.cfg file) and I honestly have no idea on how to start the emulator. What can I do? Raspberry Pi3.

That is a known issue with 4:3 displays (800x600) and no one has found a workaround but I would contact the original developer about this here:

@qfoxp
I'm not sure which es_systems.cfg you're editing but have a look at the one at /home/pi/.emulationstation/es_systems.cfg and maybe add it manually like from this post:

@backstander I did exactly that, which seems to be wrong by the way, as ES wouldn't start if I left that %$, which I fixed using

%ROM%</command>

unfortunately it still doesn't show up, I even tried putting ROMs in various places, like on a retropie-mount based usb drive, and directly on the SD. no luck.

sorry, forgot when I copy text from nano that long lines will end with '$' so I have fixed my original post adding %ROM%</command>

RetroPie's NDS Wiki says that DraStic supports .ZIP files but all of mine I have unzipped with the .nds extension and placed them in /home/pi/RetroPie/roms/nds

I'm not sure if the install script already does this now but I originally had to copy both drastic_bios_arm7.bin and drastic_bios_arm9.bin into the /home/pi/RetroPie/roms/nds/system/ directory manually.
