I have installed RetroArch on my nexus 7, and I was wondering how to get cave story to work. I tried coping the data folder, and the executable from my cave story install on my pc to my nexus 7. I navigated to the exe in RetroArch, but I just get a black screen. Even after waiting 10-20 minutes.
I was wondering if I am doing something wrong, or if anybody has had success doing this.
THANKS!
There are certain data files that the libretro port needs that are not in your PC version (such as a custom font bitmap and other things - it’s not just a straight port).
Grab the data files from here instead -
Grab the entire ‘datafiles’ folder, put it on your Android device and then run Doukutsu.exe in there - that should do it.
Thanks! Worked great!
Is there anyway i can just get the NXengine.apk? and is there a way to make it full screen? i got the xperia play 2.3.4
You can set the Aspect Ratio to whatever you want in settings.
And no, it isn’t possible to make it standalone. Although if you have root access and you need to make room on your internal storage, you could remove the other cores if you don’t need them.
BTW, a fix is being pushed later today that will fix a critical bug that happens later on in The Labyrinth.
how do i get into settings? i can bring up the screen with the save state and slow motion etc, but i dont see where to change the aspect ratio? sorry i justt really wanna make it full screen
In the menu where you get to select your ‘ROM’ - there is an icon that you need to press or something - it should show up a popup menu. Select ‘RetroArch Settings’ - go to ‘Video Settings’ - change ‘Aspect Ratio’ there.
BTW - this is all in the Manual that I even link to in the app - it’s there for a reason.
ok i got the pdf file thank you 
and when that crritical bug gets fixed in the labyrinth will it just update the app? or is there something im gonna have to do?
Just update the app and you can finish the game as intended. Going to be pushed today.
Im definitely giving 5 stars and donating, THANK YOU!
Hi, im new here and am really happy with the emulator! great work guys! However, I am having a problem with the saves on Cave story. I am using a jailbroken Iphone 5. I downloaded the datafiles folder as recommended and started the game, I used the initial save point in the starting area but it doesn’t seem to save. whenever I re-start the game it just starts from the intro. Any ideas what I need to do? Also what are peoples preferred control overlay for cave story? Thanks in advance
RetroArch only writes the saves to file when you exit cleanly. Are you exiting via the menu or by just hitting the ‘home’ button to go back to your homescreen?
There is also an autosave option in RGUI that can write to file every few seconds that can alleviate the problem.
I don’t think savestates are working on NXEngine, Well they didn’t for me on android anyway. Just use Cavestory’s internal save system as it works fine.
Thanks for the tips, unfortunately it’s not working. I activated the auto save on exit and I also made sure to exit properly from the system menu. When I save from the initial screen it says save slots available and says game saved. But when I die I press load from the start screen, it just starts the intro again and all the save slots are still empty.
Edit: yeah the save states are definitely not working as it says failed to save, but the actual save game saves aren’t working either.
Thanks guys, hopefully it’s something they can fix.
Update: I just tried to do the same on my iPad2, installed retroarch and transferred the datafiles folder as recommended, unfortunately the same problem persists with the in game saves not being recognised or being recorded.
