        @BloodDragoon Ok I got this game. It runs smoothly. Do you have a comparison using another emulator?

                @hex Hey, i saw your issue with the game Tower Bloxx on Github, tried it, there is no text on my screen, only select language screen in a white background and blue text, then it just shows the game's name and some kids in the background.

                    @hex Here it is, also for some reason it also makes a small window in the top-left corner, didn't happen in ShadowWalker.

                            In case you need J2ME games, that's the biggest database i was able to find.

                                  I'm getting an error when building the project on Ubuntu 16.04:

                                  The log continues with more errors, but I believe they are all related to these ones. I have installed the libopenjfx-java package, but that doesn't seem to help. Anyone has got any hints on how to build it in Ubuntu?

                                    @mardy On desktop you might not need the JavaFx build. You can edit the build file to skip javafx build and use the AWT build.

                                    Delete this code from build.xml file

                                      Compiling on a Raspberry Pi 3, getting this:
                                      https://hastebin.com/uqosiyopeb

                                      My guess is that I'm trying to compile using a JVM/JRE that's too old and thus flips out at more modern code? (it's OpenJDK 7, so that shouldn't be the case...)

                                      EDIT: Never mind, just realized there's install instructions for the Pi in the package folder.

                                      EDIT 2: Okay, now I'm getting:

                                      on the libretro core, in all games.

                                      Using oracle-java8-jdk.

                                      EDIT 3: Okay, installing the openjdk-8-jre package fixed this. The core works now!

                                      In case you can't compile it yourself, the libretro core can be found in the packages folder in this pre-compiled version on Sourceforge, courtesy of @recompile. From there, you should be able to follow retropie.txt, also present in the packages folder.

                                        @hex Hi, I know this topic is super old, but I was having some trouble with FreeJ2ME and thought I'd start here instead of github. I'm trying to get Resident Evil Degeneration running, and it IS running, but I'm not able to get past this screen. The program isn't accepting any keystrokes, though if I hit escape I am able to get to the game options menu. As far as I can tell all the info in my config file is correct. At a bit of a loss here! ![alt text](Screenshot 2021-08-18 202246.png Screenshot 2021-08-18 202207.png image url)

                                          Where can I find "freej2me_libretro.dll"? (in short, the Retroarch core for Windows). I know it exists somewhere but all I found searching the web left and right were some mentions on random Github codes. Help plz

                                            @9cento it's not in the buildbot so it's likely it's not automatically built: https://buildbot.libretro.com/nightly/windows/x86/latest/

                                            possibly because it doesn't build on windows at all: https://github.com/hex007/freej2me/issues/92
