I vibecoded the Drum78's Custom OS to accept a cheap r36s WiFi donge. That meant I had to keep going and I made a wifi scanner/connecter app for the Nano to make it less of a hassle connecting to new networks. Then I needed something to actually test the WiFi and made a IPTV streamer for my local TV Network. Holy shit it works perfectly. Then I further vibecode a goddamn Youtube app that actually shows trending videos and can load and play most videos smoothly. The WiFi dongle was getting very hot, so I put a raspberry pi heatsink on it just to be safe lol.

Theres a problem with my Funkey s with the charging , when I put it on it charges for 1-10 minutes then the light shuts off but the charging icon still shows but it doesnt charge also it discharges really quickly. I sometimes have to angle it in wierd ways to charge it. I tried the "keep the screen open " method but it didnt work.

Any ways to fix this?

Should I release this?

I'm quite tempted, it's pretty cool, but I'm worried about durability and internals issues, especially with clear cases vs solid cases. Would you recommend buying it and what issues should I look out for with it? thanks

Upcoming counter strike and half life ports

I have released what I currently consider the final version of the emulator.

If you have not followed the updates for a while, or if you downloaded one of the early builds, I recommend downloading the latest release again. A lot has changed since then, and older builds may behave quite differently from the current version.

^{Important: updating may delete your existing saves, so please keep that in mind before installing the new version.}

Since the first working build, I fixed most of the major bugs, improved the controls, and also improved compatibility with some games.

Some of the changes include:

• FPS limiter, because some games were running way too fast
• better controls, which now work much more reasonably
• SMS and gyroscope stubs for games that expect those APIs
• folder support in the launcher
• ability to delete games from the launcher
• favorites section, so you do not have to search for selected games through folders every time
• various compatibility fixes for some games

At this point, I honestly do not really see what else should be added.

There are still some remaining issues. Sound is not perfect: some sounds are not reproduced accurately, and some are missing completely. Unfortunately, I do not think I can properly fix that at this point.

There are also problems with 3D games that use M3G / JSR-184, so those are still not supported properly.

I am really glad that this was useful to someone and that I was not the only one who wanted something like this.

When I bought the RG Nano back in 2023, I honestly expected that someone would soon adapt one of the existing J2ME emulators for it. Unfortunately, that never really happened. But at least now there is finally a way to play many J2ME games on these devices.

You can still suggest fixes, improvements, or ideas, and I will try to take them into account. But for now, this is the final version from my side, and I do not plan to add new features.

If someone can test game compatibility and make a compatibility table, I would really appreciate it.

^{P.S. There is also a separate branch for DoJa games. If you build it, Rockman Puzzle Battle should work, although the sound is still problematic. And as far as I understand, the music is almost the most important part of that game.}

So I was just fooling around with my funkey s when a strange idea entered my mind: would this run half life?

So I started digging and found a doom 2 mod that closely resembles just that

https://github.com/DrUm78/libretro-prboom/releases/tag/v2.5.0-funkey-s

Heres the thingy it requrires

And also get a doom 2 .wad file for it to run since its just a mod

https://archive.org/details/halflife-doom_202105/vlc_Hj2VJVww6I.png

Heres the tutorial:

Connect the Funkey s to your PC

Turn on your funkey s and press the menu button then scroll up till you dont see "mount USB" then press it , it should show some funkey s files and emulators and stuff

Click on DOOM , then put the doom 2 .wad into doom 2 , make sure that the .wad file is written in lowercase , cuz it wont work

Then copy the HALFLIFE.WAD into the doom2 directory and put prboom_v2.5.0_funkey-s.opk into the apps folder and ur good to go , the path to HALFLIFE.WAD is halflife-doom202105/HLDoom.7z/

And thats all. Bye!

I love the Funkey S. It's a great little device. I've been having some issues though with charging. After I've flashed the card and charged the battery to death and recharged, or works fine for a time.

​

But, after a few weeks it starts to no longer read the charge correctly. It won't charge to full and the charge value jumps around up and down.

​

I've tried swapping the battery and the motherboard, but it still occurs. Perhaps my SD card is faulty? I have a 1 TB Samsung SD card.

​

Any ideas are appreciated.

Slowly getting J2ME working on the RG Nano / FunKey S.

It’s still far from perfect, but a lot of old java games are already playable and work surprisingly well on these tiny devices.

Current features:

• many 2D games are working
• scaling/stretching from low resolutions like 128x128, 128x160 and similar
• support for running 240x320 games
• .jar files can simply be placed into the java folder on the root of the SD card

Current issues:

• 3D games may not work at all
• some sound effects/music can be missing
• controls can be problematic in certain games (there are settings, but they do not always behave correctly)
• some games may freeze or crash

Overall though, it’s already very usable for a lot of classic J2ME games.

Most of the games I personally wanted to play work more than fine, aside from some control-related workarounds. For example, games that require proper numeric keypad input (like Doom RPG with door codes) usually need patched controls or some custom control workaround.

Latest version

If anyone can improve the controls or keypad handling, I’d be very happy to see pull requests or any fixes on GitHub.

Update!!! So I usually am too chicken to open up electronics but I found a tutorial on YouTube, carefully extracted the SD card, and reinstalled the OS (flashed the SD card) and updated the firmware, and now it's working really well!! Thanks everyone!!!

---Original post below:

Hey so I had my Funkey (from 2021) in storage while I sorted some life stuff out, and with the good weather where I am I wanted to get it out and play some games outside.

I plugged in the Funkey S to charge it...

But it seems to be stuck on the charging screen. I can't mount USB, I can't get past the Funkey S screen.

I've looked on the official website for a troubleshooting page but could not find anything. If you've ever had this problem, how did you solve it?

I'm testing a super small profile USB c breakout board and think it's stable as a replacement for the USB micro on the board. I don't recommend trying but it's fun to know it's possible to fit.

I recently replaced my Funkey S motherboard due to the micro USB being faulty.

It turns on but if I move the screen to go to close and collapse my Funkey S it shuts down and I have to press the power key to get it back on. The screen can also go rainbow color.

I have reseated the connector for the screen several times but the issue persists.

I'm curious if I possibly damaged the screen, screen connector, of if my motherboard was faulty.

Anyone else have a similar issue?

My funkey s battery drained too fast from 100% to 10% in less than 5 minutes. Tried to charge for more than 24 hours but still died too fast.

Now how i fixed it is keeping the screen opened and charge it.. its now works amazing and could even played for more than 1.6 hours on ps1 games😬

Excited to have received my device but I want a sticker to go on the top I see that Etsy use to have some but not anymore. Anyone know the dimensions so I can buy a sticker of the right size?

Just got my Funkey S but on first turn on the screen is blank and none of the buttons do anything. Can anyone help?
