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

@An0nymouse said in DraStic (Nintendo DS emulator) OUT NOW for pi2/3!:

The one where after running drastic once, run command no longer functions

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:
https://retropie.org.uk/forum/topic/7435/drastic-nintendo-ds-emulator-out-now-for-pi2-3/53

@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.

joyrider3774

btw drastic supports 7z files (confirmed i tested this) and might support rar files as well. (not tested but did see something about this on the drastic forum) . So you change any romlisting to adopt for this it's not only *.nds and *.zip as the wiki said although i think the wiki shows info specific for the dsemu emulator .

Is there a workaround for the emulator not restoring the framebuffer ?

The author posted a progress report here yesterday for anyone who is interested.

AlexMurphy

@mediamogul That is great. I think DraStic is a fantastic emu... for a closed source project. Hopefully a few bugs will be sorted. Exophase seems like he wants to put the time and effort into really making it work on the Pi.

@AlexMurphy

I wish it was open-sourced myself, but the thing runs circles around everything else and it's hard to complain when such a great piece of software is being offered up for no cost. I actually bought the android version about two years ago and it was well worth it for all the entertainment it's given in that time.

AlexMurphy

@mediamogul Yeah, I've tried lr-desmumeit barely runs at 5-10 fps. DraStic is a brilliant addition to RetroPie. The more encouragement Exophase gets to keep supporting it the better. i tortured him on the DraStic forum and asked for a Pi specific sub. Hopefully that will happen and we can get book-mode and mic support added.

I poured sugar in his gas tank and asked for 3DS support. All I got was a restraining order.
