Is it possible to transport the project to some popular open source handheld based on rk3566 (ARM64-A53) or rk3326(ARM32-a35?) with Jeos or arkos ?

These retro game consoles based on Rk3566 (ARM64-A53) or rk3326(ARM32-a35?) with Jeos or Arkos handheld are veay popular, have many models and shapes style , high performance and low cost(below 100$). So if it can transport to these platform, it will be a big superise for the kids who are interesting in makecode arcade.

Hi @whmzsu,

Thanks for your interest in McAirpos and nice ideas for other popular and handheld systems to be supported! Sorry also for my late reply.

In general, McAirpos, which is only a launcher with some help for setting up controllers, could be compiled to any system, since the source files are here and e.g. the uinput-mapper module runs in Python.

The compatibility for different systems, lies in the MakeCode Arcade executable .elf game file itself, which has these properties: arcade-jumpy-platformer.elf: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 2.6.26, BuildID[sha1]=1345002c7e1eb0f7585105314513524afbaf24dd, stripped

This means that these MakeCode Arcade .elf game files in theory should run on any ARM 32-bit Linux system/distribution(Also on 64-bit systems, if you include the 32-bit runtime, which I do for the Batocera installation, which is 64-bit).

One important and known requirement is that Alsa sound is included and positioned as the first available audio device, position 0:0.

If not ARM or Linux based, you have to check out other options for support: https://arcade.makecode.com/hardware

PS: It would be nice to hear back from you about what you have found out about this subject!

Hi @Vegz78 ，Yestoday I finally have some time to try installing the project on my small handheld game console by following the "Manual installation for RetroPie/RPi OS", and the result of course is "Failed". But I got some progress: 1 I only can start the game under remote ssh console like "sudo ~/McAirpos/McAirpos/launCharc/launCharc no map ~/RetroPie/roms/makecode/gamefile.elf" with "nomap" parameter, I think maybe it's relative to the "[uinput-mapper]" because there no install steps about this in the "Manual installation ". 2 I confige the key map by edit the /sd/arcade.cfg file by getting the key code with evtest. 3 I only can start the game with "sudo" command like above or got error. 4 After start the game by the remote console command , the games appeared run OK but with flicker screen because the emulationstation UI is still there, controller working on both UI and the game at same time. 5 The manual keymap seems worded , and the sound seems worked too. 6 Launch the game from the emulationstation not work with the same cmd line in the "es_system.cfg" file . Black screen or back to Emulationstation wait about 15 sec.

So I will try the install process on this weekend and log the error messages to post on this subject.

I got a quick log of the test process 。The game can launch without root privilege on the remote ssh console.
